description: This paper presents the results of several successful profiled side-channel attacks against a secure implementation of the RSA algorithm. The implementation was running on a ARM Core SC 100 completed with a certified EAL4+ arithmetic co-processor. The analyses have been conducted by three experts’ teams, each working on a specific attack path and exploiting information extracted either from the electromagnetic emanation or from the power consumption. A particular attention is paid to the description of all the steps that are usually followed during a security evaluation by a laboratory, including the acquisitions and the observations preprocessing which are practical issues usually put aside in the literature. Remarkably, the profiling portability issue is also taken into account and different device samples are involved for the profiling and testing phases. Among other aspects, this paper shows the high potential of deep learning attacks against secure implementations of RSA and raises the need for dedicated countermeasures.

Decomposition driven interface evolution for layers of binary mixtures: {II}. Influence of convective transport on linear stability

description: We study the linear stability with respect to lateral perturbations of free surface films of polymer mixtures on solid substrates. The study focuses on the stability properties of the stratified and homogeneous steady film states studied in Part I [U. Thiele, S. Madruga and L. Frastia, Phys. Fluids 19, 122106 (2007)]. To this aim, the linearized bulk equations and boundary equations are solved using continuation techniques for several different cases of energetic bias at the surfaces, corresponding to linear and quadratic solutal Marangoni effects. For purely diffusive transport, an increase in film thickness either exponentially decreases the lateral instability or entirely stabilizes the film. Including convective transport leads to a further destabilization as compared to the purely diffusive case. In some cases the inclusion of convective transport and the related widening of the range of available film configurations (it is then able to change its surface profile) change the stability behavior qualitatively. We furthermore present results regarding the dependence of the instability on several other parameters, namely, the Reynolds number, the Surface tension number and the ratio of the typical velocities of convective and diffusive transport.

description: We have performed ultrafast pump-probe spectroscopy studies on a series of InAs/GaSb-based short-period superlattice (SL) samples with periods ranging from 46 Åto 71 Å. We observe two types of oscillations in the differential reflectivity with fast ($\sim$ 1- 2 ps) and slow ($\sim$ 24 ps) periods. The period of the fast oscillations changes with the SL period and can be explained as coherent acoustic phonons generated from carriers photoexcited within the SL. This mode provides an accurate method for determining the SL period and assessing interface quality. The period of the slow mode depends on the wavelength of the probe pulse and can be understood as a propagating coherent phonon wavepacket modulating the reflectivity of the probe pulse as it travels from the surface into the sample.

Towards Globally Optimized Masking: From Low Randomness to Low Noise Rate

Publisher: name: IACR Transactions on Cryptographic Hardware and Embedded Systems
Year: 2019

description: We improve the state-of-the-art masking schemes in two important directions. First, we propose a new masked multiplication algorithm that satisfies a recently introduced notion called Probe-Isolating Non-Interference (PINI). It captures a sufficient requirement for designing masked implementations in a trivial way, by combining PINI multiplications and linear operations performed share by share. Our improved algorithm has the best reported randomness complexity for large security orders (while the previous PINI multiplication was best for small orders). Second, we analyze the security of most existing multiplication algorithms in the literature against so-called horizontal attacks, which aim to reduce the noise of the actual leakages measured by an adversary, by combining the information of multiple target intermediate values. For this purpose, we leave the (abstract) probing model and consider a specialization of the (more realistic) noisy leakage / random probing models. Our (still partially heuristic but quantitative) analysis allows confirming the improved security of an algorithm by Battistello et al. from CHES 2016 in this setting. We then use it to propose new improved algorithms, leading to better tradeoffs between randomness complexity and noise rate, and suggesting the possibility to design efficient masked multiplication algorithms with constant noise rate in F2.

description: At finite density parity can be spontaneously broken in strong interactions with far reaching implications. In particular, a time-dependent pseudoscalar background would modify QED by adding a Chern-Simons term to the lagrangian. As a striking consequence we propose a novel explanation for the dilepton excess observed in heavy ion collisions at low invariant masses. The presence of local parity breaking due to a time-dependent pseudoscalar condensate substantially modifies the dispersion relation of photons and vector mesons propagating in such a medium, changing the $ρ$ spectral function and resulting in a potentially large excess of dileptons with respect to the predictions based in a `cocktail' of known processes.

description: Voltage fault injection is a powerful active side channel attack that modifies the execution-flow of a device by creating disturbances on the power supply line. The attack typically aims at skipping security checks or generating side-channels that gradually leak sensitive data, including the firmware code. In this paper we propose a new voltage fault injection technique that generates fully arbitrary voltage glitch waveforms using off-the-shelf and low cost equipment. To show the effectiveness of our setup, we present new, unpublished firmware extraction attacks on six microcontrollers from three major manufacturers: STMicroelectronics, Texas Instruments and Renesas Electronics that, in 2016 declared a market of $1.5 billion, $800 million and $2.5 billion on units sold, respectively. Among the presented attacks, the most challenging ones exploit multiple vulnerabilities and inject over one million glitches, heavily leveraging on the performance and repeatability of the new proposed technique. We perform a thorough evaluation of arbitrary glitch waveforms by comparing the attack performance against two other major V-FI techniques in the literature. Along a responsible disclosure policy, all the vulnerabilities have been timely reported to the manufacturers.

description: In the littlest Higgs model with T-parity (LHT) the mirror quarks induce the special flavor structures and some new flavor-changing (FC) couplings which could greatly enhance the production rates of the FC processes. We in this paper study some bottom and anti-strange production processes in the LHT model at the International Linear Collider (ILC), i.e., $e^+e^-\rightarrow b\bar{s}$ and $γγ\rightarrow b\bar{s}$. The results show that the production rates of these processes are sizeable for the favorable values of the parameters. Therefore, it is quite possible to test the LHT model or make some constrains on the relevant parameters of the LHT through the detection of these processes at the ILC.

Analysis and Improvement of Differential Computation Attacks against Internally-Encoded White-Box Implementations
Creators: name: Rivain, Matthieu
name: Wang, Junwei
Publisher: name: IACR Transactions on Cryptographic Hardware and Embedded Systems
Year: 2019

description: White-box cryptography is the last security barrier for a cryptographic software implementation deployed in an untrusted environment. The principle of internal encodings is a commonly used white-box technique to protect block cipher implementations. It consists in representing an implementation as a network of look-up tables which are then encoded using randomly generated bijections (the internal encodings). When this approach is implemented based on nibble (i.e. 4-bit wide) encodings, the protected implementation has been shown to be vulnerable to differential computation analysis (DCA). The latter is essentially an adaptation of differential power analysis techniques to computation traces consisting of runtime information, e.g., memory accesses, of the target software. In order to thwart DCA, it has then been suggested to use wider encodings, and in particular byte encodings, at least to protect the outer rounds of the block cipher which are the prime targets of DCA.
In this work, we provide an in-depth analysis of when and why DCA works. We pinpoint the properties of the target variables and the encodings that make the attack (in)feasible. In particular, we show that DCA can break encodings wider than 4-bit, such as byte encodings. Additionally, we propose new DCA-like attacks inspired from side-channel analysis techniques. Specifically, we describe a collision attack particularly effective against the internal encoding countermeasure. We also investigate mutual information analysis (MIA) which naturally applies in this context. Compared to the original DCA, these attacks are also passive and they require very limited knowledge of the attacked implementation, but they achieve significant improvements in terms of trace complexity. All the analyses of our work are experimentally backed up with various attack simulation results. We also verified the practicability of our analyses and attack techniques against a publicly available white-box AES implementation protected with byte encodings –which DCA has failed to break before– and against a “masked” white-box AES implementation –which intends to resist DCA.

description: Implementing the masking countermeasure in hardware is a delicate task. Various solutions have been proposed for this purpose over the last years: we focus on Threshold Implementations (TIs), Domain-Oriented Masking (DOM), the Unified Masking Approach (UMA) and Generic Low Latency Masking (GLM). The latter generally come with innovative ideas to cope with physical defaults such as glitches. Yet, and in contrast to the situation in software-oriented masking, these schemes have not been formally proven at arbitrary security orders and their composability properties were left unclear. So far, only a 2-cycle implementation of the seminal masking scheme by Ishai, Sahai and Wagner has been shown secure and composable in the robust probing model – a variation of the probing model aimed to capture physical defaults such as glitches – for any number of shares.
In this paper, we argue that this lack of proofs for TIs, DOM, UMA and GLM makes the interpretation of their security guarantees difficult as the number of shares increases. For this purpose, we first put forward that the higher-order variants of all these schemes are affected by (local or composability) security flaws in the (robust) probing model, due to insufficient refreshing. We then show that composability and robustness against glitches cannot be analyzed independently. We finally detail how these abstract flaws translate into concrete (experimental) attacks, and discuss the additional constraints robust probing security implies on the need of registers. Despite not systematically leading to improved complexities at low security orders, e.g., with respect to the required number of measurements for a successful attack, we argue that these weaknesses provide a case for the need of security proofs in the robust probing model (or a similar abstraction) at higher security orders.

Reducing a Masked Implementation’s Effective Security Order with Setup Manipulations

description: Couplings are a type of physical default that can violate the independence assumption needed for the secure implementation of the masking countermeasure. Two recent works by De Cnudde et al. put forward qualitatively that couplings can cause information leakages of lower order than theoretically expected. However, the (quantitative) amplitude of these lower-order leakages (e.g., measured as the amplitude of a detection metric such as Welch’s T statistic) was usually lower than the one of the (theoretically expected) dth order leakages. So the actual security level of these implementations remained unaffected. In addition, in order to make the couplings visible, the authors sometimes needed to amplify them internally (e.g., by tweaking the placement and routing or iterating linear operations on the shares). In this paper, we first show that the amplitude of low-order leakages in masked implementations can be amplified externally, by tweaking side-channel measurement setups in a way that is under control of a power analysis adversary. Our experiments put forward that the “effective security order” of both hardware (FPGA) and software (ARM-32) implementations can be reduced, leading to concrete reductions of their security level. For this purpose, we move from the detection-based analyzes of previous works to attack-based evaluations, allowing to confirm the exploitability of the lower-order leakages that we amplify. We also provide a tentative explanation for these effects based on couplings, and describe a model that can be used to predict them in function of the measurement setup’s external resistor and implementation’s supply voltage. We posit that the effective security orders observed are mainly due to “externally-amplified couplings” that can be systematically exploited by actual adversaries.

The unstable behaviour of tensor perturbations is derived in a very simple way in Hwang's covariant and gauge-invariant formalism developed for extended theories of gravity. A simple interpretation of this instability as the effect of an "antifriction" is given, and it is argued that a universe must eventually enter the expanding phase.

Multi-Tuple Leakage Detection and the Dependent Signal Issue
Creators: name: Bronchain, Olivier

name: Standaert, François-Xavier
Publisher: name: IACR Transactions on Cryptographic Hardware and Embedded Systems
Year: 2019

description: Leakage detection is a common tool to quickly assess the security of a cryptographic implementation against side-channel attacks. The Test Vector Leakage Assessment (TVLA) methodology using Welch’s t-test, proposed by Cryptography Research, is currently the most popular example of such tools, thanks to its simplicity and good detection speed compared to attack-based evaluations. However, as any statistical test, it is based on certain assumptions about the processed samples and its detection performances strongly depend on parameters like the measurement’s Signal-to-Noise Ratio (SNR), their degree of dependency, and their density, i.e., the ratio between the amount of informative and non-informative points in the traces. In this paper, we argue that the correct interpretation of leakage detection results requires knowledge of these parameters which are a priori unknown to the evaluator, and, therefore, poses a non-trivial challenge to evaluators (especially if restricted to only one test). For this purpose, we first explore the concept of multi-tuple detection, which is able to exploit differences between multiple informative points of a trace more effectively than tests relying on the minimum p-value of concurrent univariate tests. To this end, we map the common Hotelling’s T2-test to the leakage detection setting and, further, propose a specialized instantiation of it which trades computational overheads for a dependency assumption. Our experiments show that there is not one test that is the optimal choice for every leakage scenario. Second, we highlight the importance of the assumption that the samples at each point in time are independent, which is frequently considered in leakage detection, e.g., with Welch’s t-test. Using simulated and practical experiments, we show that (i) this assumption is often violated in practice, and (ii) deviations from it can affect the detection performances, making the correct interpretation of the results more difficult. Finally, we consolidate our findings by providing guidelines on how to use a combination of established and newly-proposed leakage detection tools to infer the measurements parameters. This enables a better interpretation of the tests’ results than the current state-of-the-art (yet still relying on heuristics for the most challenging evaluation scenarios).

Implementation of a coherent Lyman-alpha source for laser cooling and spectroscopy of antihydrogen
Creators: name: Michan, Juan Mario
Publisher: name: University of British Columbia
Year: 2014

description: This dissertation describes two related projects: the development of a coherent Lyman-α source and the implementation of a supersonic hydrogen beam. A two-photon resonance-enhanced four wave mixing process in krypton is used to generate high power coherent radiation at ωLy_α ⇒ 121.56 nm, the hydrogen Lyman-α line, to perform spectroscopy and cooling of magnetically trapped antihydrogen (1s − 2p transition). This is a tool to directly test both the Einstein Equivalence Principle and Charge, Parity, and Time inversion symmetry. The former can be tested by measuring the gravity interaction of matter and antimatter. Inversion symmetry can be tested by comparing the spectroscopic properties of hydrogen and antihydrogen. Both experiments require optically cooled antihydrogen. Under the current trapping conditions, optical cooling could be performed with nanosecond long pulses of 0.1 μJ of Lyman-α radiation at a repetition rate of 10 Hz. The process to generate Lyman-α radiation uses two wavelengths (ωR ⇒ 202.31 nm and ωT ⇒ 602.56 nm), which are mixed in a sum-difference scheme (ωLy_α = 2ωR−ωT ) with a two-photon resonance at (4s²4p⁵5p[1/2]₀ ← 4s²4p⁶(¹S₀) ). The source implemented produces 1.2 μW at the Lyman-α line and this was confirmed by performing spectroscopy of hydrogen. The design, implementation and characterization of the source are discussed in this dissertation. In the second part of the dissertation the implementation of the hydrogen beam and its characterization are discussed. The atomic hydrogen is generated with a thermal effusive source and it is entrained by an expanding noble gas. This process generates a cold beam of hydrogen atoms. Hydrogen is separated from the noble gas with a Zeeman bender that uses the forces generated by the Zeeman shift of low field seeking states of hydrogen and engineered magnetic field gradients. The hydrogen beam was characterized with a quadrupole mass spectrometer. The seed noble gas beam was characterized by colliding it with ultra-cold rubidium atoms in a magneto-optical trap. The trapped atoms loss rate resulting from these collisions can be used to measure the density of the atomic beam. This measurement demonstrates the potential of using magneto-optical traps as absolute flux monitors.

description: The ATLAS Collaboration recently reported strong modifications of dijet properties in heavy ion collisions. In this work, we discuss to what extent these first data constrain already the microscopic mechanism underlying jet quenching. Simple kinematic arguments lead us to identify a frequency collimation mechanism via which the medium efficiently trims away the soft components of the jet parton shower. Through this mechanism, the observed dijet asymmetry can be accomodated with values of $\hat{q}\, L$ that lie in the expected order of magnitude.

description: Secure report is the problem of a client that retrieves all records matching specified attributes from a database table at the server (e.g. cloud), as in SQL SELECT queries, but where the query and the database are encrypted. Here, only the client has the secret key, but still the server is expected to compute and return the encrypted result. Secure report is theoretically possible with Fully Homomorphic Encryption (FHE). However, the current state-of-the-art solutions are realized by a polynomial of degree that is at least linear in the number m of records, which is too slow in practice even for very small databases.
 We present the first solution that is realized by a polynomial that attains degree independent of the number of records m, as well as the first implementation of an FHE solution to Secure report. This is by suggesting a novel paradigm that forges a link between cryptography and modern data summarization techniques known as coresets (core-sets), and sketches in particular. The key idea is to compute only a coreset of the desired report. Since the coreset is small, the client can quickly decode the desired report that the server computes after decrypting the coreset.
 We implemented our main reporting system in an open source library. This is the first implemented system that can answer such database queries when processing only FHE encrypted data and queries. As our analysis promises, the experimental results show that we can run Secure report queries on billions records in minutes on an Amazon EC2 server, compared to less than a hundred-thousands in previous FHE based solutions.

description: Using a full spectral scan of an active region from the Extreme-Ultraviolet Imaging Spectrometer (EIS) we have obtained Emission Measure EM$(T)$ distributions in two different moss regions within the same active region. We have compared these with theoretical transition region EMs derived for three limiting cases, namely \textit{static equilibrium}, \textit{strong condensation} and \textit{strong evaporation} from \cite{ebtel}. The EM distributions in both the moss regions are strikingly similar and show a monotonically increasing trend from $\log T[\mathrm{K}]=5.15 -6.3$. Using photospheric abundances we obtain a consistent EM distribution for all ions. Comparing the observed and theoretical EM distributions, we find that the observed EM distribution is best explained by the \textit{strong condensation} case (EM$_{con}$), suggesting that a downward enthalpy flux plays an important and possibly dominant role in powering the transition region moss emission. The downflows could be due to unresolved coronal plasma that is cooling and draining after having been impulsively heated. This supports the idea that the hot loops (with temperatures of 3{-}5 MK) seen in the core of active regions are heated by nanoflares.

description: We present high-resolution ($0\farcs2$) near-infrared images of the area surrounding the Herbig Be star LkH$α$ 234 taken with the Coronagraphic Imager with Adaptive Optics (CIAO) and the adaptive optics on the Subaru Telescope. The near-infrared ($J$, $H$, $K$, $L'$ and $M'$ bands) images reveal circumstellar structures around LkH$α$ 234 in detail. Eight young stellar object (YSO) candidates (Object B, C, D, E, F, G, NW1, and NW2) were detected at 2$\arcsec$--11$\arcsec$ from LkH$α$ 234. Objects B and C are likely variable stars, which is consistent with a young evolutionary status. Three objects (LkH$α$ 234, NW1, and NW2) were identified in the 11.8 $\micron$ (SiC) and 17.65 $\micron$ images obtained with the Long Wavelength Spectrometer (LWS) on the Keck Telescope. NW1 and NW2 are thought to be embedded young stars. We suggest that NW1 and not LkH$α$ 234 is the source illuminating the reflection nebula west of LkH$α$ 234, although Object G may be another candidate. In our images, these objects are located at the center of the 2 $\micron$ polarization, and NW1 resides at the center of a monopolar cavity. The SED of NW1 suggests that it is a YSO with a spectral type of B6--7. Object F and G were discovered by our observations at $1\farcs9$ and $2\farcs3$, respectively, from LkH$α$ 234, and their proximity to LkH$α$ 234 suggests that they may be its lower-mass companions.

description: ? Eucytherura boomeri n.sp. Fig. 2 A-D Etymology. For Dr lan Boomer in recognition of his innovative work on deep-sea Ostracoda. Type material and dimensions. Holotype, AMF 91141, adult left valve, length 0.25 mm, height 0.12 mm. Paratype: AMF 91142, adult right valve, length 0.24 mm, height 0.13 mm. Both specimens are from the type locality and horizon. Type locality and horizon. Western flank of Lord Howe Rise, present day water depth 1340 m, Sonne core 36- 61, interval 12-13 cm, Late Pleistocene. Diagnosis. ? Eucytherura with convex dorsal margin, low longitudinal ridges and intercostal reticulation in posterior half. Reticulation grades to dense punctation distally. Weakly alate posteroventrally. Median hinge element smuous. Description. Very small, subovate in lateral and dorsal view, shell moderately well calcified. Anterior margin convex; posterior margin short and convex. Dorsal margin convex, weakly undulating; ventral margin gently biconvex. Weakly inflated, slightly longitudinally swollen posteroventrally. Diffuse longitudinal ridges through posterior half with intercostal reticulation bounding well rounded fossae and secondarily reticulate, grading to fine, dense punctation distally. Adductor muscle scars large, four in a subvertical row anteroventral of valve centre, frontal scar subreniform, just ahead or dorsomedian adductor scar; normal pores, simple and well distributed, internally emergent at base of large pits. Antimerodont hinge: finely crenulate, flexured median element; in RV, terminal elements finely denticulate, narrow and elongate, tapering under ends of median element. Inner lamella moderately broad anteriorly, with small crescentic vestibulum, narrow ventrally with narrow vestibulum. Few radial pore canals, 4 -5 true anteriorly, 3 posteroventrally. Comparisons. The species can be distinguished from ? E. polydictyota n.sp. by its more curved dorsal margin, less distinct ridges and reticulation, and lack of an alar ridge. It is placed only tentatively within Eucytherura due to its lack of normal pore clusters. Distribution. Found only in the Late Quaternary of the type locality.

AuCPace: Efficient verifier-based PAKE protocol tailored for the IIoT

description: Increasingly connectivity becomes integrated in products and devices that previously operated in a stand-alone setting. This observation holds for many consumer applications in the so-called "Internet of Things" (IoT) as well as for corresponding industry applications (IIoT), such as industrial process sensors. Often the only practicable means for authentication of human users is a password. The security of password-based authentication schemes frequently forms the weakest point of the security infrastructure.
 In this paper we first explain why a tailored protocol designed for the IIoT use case is considered necessary. The differences between IIoT and the conventional Internet use-cases result in largely modified threats and require special procedures for allowing both, convenient and secure use in the highly constrained industrial setting. Specifically the use of a verifier-based password-authenticated key-exchange (V-PAKE) protocol as a hedge against public-key-infrastructure (PKI) failures is considered important. Availability concerns for the case of failures of (part of) the communication infrastructure makes local storage of access credentials mandatory. The larger threat of physical attacks makes it important to use memory-hard password hashing. This paper presents a corresponding tailored protocol, AuCPace, together with a security proof within the Universal Composability (UC) framework considering fully adaptive adversaries.
We also introduce a new security notion of partially augmented PAKE that provides specific performance advantages and makes them suitable for a larger set of IIoT applications. We also present an actual instantiation of our protocol, AuCPace25519, and present performance results on ARM Cortex-M0 and Cortex-M4 microcontrollers. Our implementation realizes new speed-records for PAKE and X25519 Diffie-Hellman for the ARM Cortex M4 architecture.

The petrology and petrogenesis of the Ren carbonatite sill and fenites, southeastern British Columbia, Canada
Creators: name: Ya'acoby, Avee

description: This thesis explores in detail the petrology and petrogenesis of the Ren carbonatite sill and associated fenites, located in the Monashee mountain range of British Columbia. The carbonatite body and fenites have been significantly deformed and metamorphosed, which has provided a unique petrological research opportunity, since only a few other carbonatite occurrences worldwide have been described from highly metamorphosed orogenic settings. This work aims to address knowledge gaps pertaining to the petrology, petrogenesis and economic exploration of comparable carbonatites in similar geotectonic settings. The effects of amphibolite facies regional metamorphism and progressive deformation are apparent throughout the carbonatite body and adjacent fenites. Many of the rocks display remobilized, passively mixed components, boudinaged structures, and rheomorphic bands, as well as foliation and porphyroblastic textures. Recrystallization of minerals at peak metamorphic conditions (580–730 °C) is indicated primarily in undifferentiated calcite for which metamorphic solvus temperatures (~690 °C) were derived. Other minerals related to metamorphic recrystallization include rims of monazite-(Ce) around earlier fluorapatite, interstitial REE-silicates, and Ca- and Mg-amphibole forming late in the paragenetic sequence, after primary silicates. Despite the metamorphic overprint and alteration, many petrological features pertaining to the igneous paragenetic record have been preserved, such as textures of primary minerals, compositional trends in phlogopite, clinopyroxene and amphibole, and whole-rock geochemistry of rock units. Solvus temperatures (~760 °C) of calcite, higher than peak metamorphic conditions, highlight preservation of the igneous component. The carbonatite is inferred to be a product of primitive mantle melts(s) that did not undergo significant fractionation processes, and intruded the crustal environment relatively undifferentiated. The whole-rock compositional trend of the fenites and partially fenitized host rocks suggests sodic-potassic alteration of the country rock during emplacement of the carbonatite sill. The Nb-Ta and REE mineralizations of the Ren occurrence are both insufficient for economic extraction. Nevertheless, rare and new mineral candidates, (Fe,OH)-analogue to västmanlandite-(Ce) and (Mg)-analogue to biraite-(Ce), discovered in the deposit by the author, emphasize its petrological and mineralogical significance.

This species is closely similar to the Pacific Eucytherura batalaria n.sp. but differs from that species in having a posterodorsal tubercle and less rugose ornament. The specimen illustrated by Whatley & Coles (1987) displays a rather weakly developed posteroventral tubercle and is here considered to be a variant of this species. Ruan & Hao (1988) illustrate a very similar form found in Quaternary sediments of the Okinawa Trough which, although it has an unusally high anterior hinge ear for this species, is probably conspecific. Distribution. Found in this study in the Late Pleistocene of Tasman Sea cores Sonne 36-61, 1-86/6GC3 and Coral Sea DSDP core 209.

description: Using information-theoretic tools, this paper establishes a mathematical link between the probability of success of a side-channel attack and the minimum number of queries to reach a given success rate, valid for any possible distinguishing rule and with the best possible knowledge on the attacker’s side. This link is a lower bound on the number of queries highly depends on Shannon’s mutual information between the traces and the secret key. This leads us to derive upper bounds on the mutual information that are as tight as possible and can be easily calculated. It turns out that, in the case of an additive white Gaussian noise, the bound on the probability of success of any attack is directly related to the signal to noise ratio. This leads to very easy computations and predictions of the success rate in any leakage model.
