A Single-Board Computing Constellation Supporting Integration of Hands-On Cybersecurity Laboratories into Operating Systems Courses

Integration of relevant hands-on cybersecurity content into laboratories supporting our required operating systems course helps to provide all computing students a baseline level of cybersecurity knowledge, even if those students never enroll in a dedicated cybersecurity course. However, these hands-on laboratories often require rebuilding of kernels, capturing network traffic, running offensive cybersecurity tools, so that they either require dedicated computer infrastructure, thus increasing the costs in budget-strapped higher education institutions or frequent administrative actions in case of shared infrastructure. To address this problem, we have developed a low-cost single-board computing constellation and support infrastructure as a cost-effective means of delivering both instruction in traditional operating systems topics and related cybersecurity concepts, such as two-factor authentication and isolation via virtualization. Use of physical infrastructure instead of virtualized laboratory infrastructure has several advantages. The computing constellation offers simplified configuration and management, flexibility, isolation, deployment of diverse laboratory assignments, and uniformity of user experience. The use of physical infrastructure built upon a low-cost single board computer makes the computing constellation scalable to address rising enrollments. This paper includes an overview of the security-focused laboratories added to the operating systems course, and the construction and operation of the computing constellation infrastructure so that other educators may replicate the infrastructure and integrate similar hands-on cybersecurity laboratories into their existing computing curriculum.

A Correlation-Preserving Fingerprinting Technique for Categorical Data in Relational Databases

Fingerprinting is a method of embedding a traceable mark into digital data, to verify the owner and identify the recipient a certain copy of a data set has been released to. This is crucial when releasing data to third parties, especially if it involves a fee, or if the data is of sensitive nature, due to which further sharing and leaks should be discouraged and deterred from. Fingerprinting and watermarking are well explored in the domain of multimedia content, such as images, video, or audio.The domain of relational databases is explored specifically for numerical data types, for which most state-of-art techniques are designed. However, many datasets also, or even exclusively, contain categorical data.We, therefore, propose a novel approach for fingerprinting categorical type of data, focusing on preserving the semantic relations between attributes, and thus limiting the perceptibility of marks, and the effects of the fingerprinting on the data quality and utility. We evaluate the utility, especially for machine learning tasks, as well as the robustness of the fingerprinting scheme, by experiments on benchmark data sets.

An Optimizing Protocol Transformation for Constructor Finite Variant Theories in Maude-NPA

Maude-NPA is an analysis tool for cryptographic security protocols that takes into account the algebraic properties of the cryptosystem. Maude-NPA can reason about a wide range of cryptographic properties. However, some algebraic properties, and protocols using them, have been beyond Maude-NPA capabilities, either because the cryptographic properties cannot be expressed using its equational unification features or because the state space is unmanageable. In this paper, we provide a protocol transformation that can safely get rid of cryptographic properties under some conditions. The time and space difference between verifying the protocol with all the crypto properties and verifying the protocol with a minimal set of the crypto properties is remarkable. We also provide, for the first time, an encoding of the theory of bilinear pairing into Maude-NPA that goes beyond the encoding of bilinear pairing available in the Tamarin tool.

Towards Coordinated Autoscaling and Application Brownout at the Orchestrator Level

Modern cloud applications are expected to continuously provide adequate performance, withstanding changing workloads, heterogeneous hardware, and unpredictable infrastructure failures. Autoscaling can automatically provision resources to match performance goals but may suffer from slower reaction times and risks of over-provisioning. Brownout mechanisms, on the other hand, empower applications with the ability to quickly dim out optional features, freeing computational resources to serve core functionalities with the desired performance level. However, modifying an application to include brownout capabilities may require invasive changes to the codebase and the need to expose ad-hoc interfaces to coordinate the interaction of the brownout dimmers and autoscaling actions, avoiding interferences that may destabilize the system. In this paper, we report on our preliminary results on the design of an application-agnostic control theoretical solution to integrate scaling and dimming capabilities at the orchestrator level. We implemented a prototype of our controller on top of Kubernetes and HAProxy to empower generic applications with coordinated autoscaling and brownout capabilities by dynamically controlling the number of active replicas and per-user access to optional API endpoints.
Research on Remote Attestation Technology Based on Formal Software Behavior Measurement

The traditional static measurement method based on data integrity measurement can only prove that the software has not been tampered with, and cannot describe the software behavior status. Dynamic measurement can measure the software behavior in real time, but there is no doubt that it requires a lot of computing resources. In this paper, we propose static measurement architecture PMA, which using formal method to abstract and verify software behavior. In PMA, formal language abstracts software behavior, formal specification describes security policy, and software behavior measurement problem is transformed into formal proof. We also have implemented the corresponding code according to the PMA design principle. The experimental test verifies the feasibility of the PMA architecture.

An Interactive Augmented Reality Volume Rendering Mobile Application

Throughout the past several years, the new technologies and enhancements related to medical visualization has been more than fascinating. In this study, we discuss a proposed idea of a handheld or a mobile Augmented Reality (AR) application. This application will ease the process of medical visualization. The criticality of a faulty medical imaging diagnosis could lead to severe consequences and outcomes to patients’ health. This criticality is what ignites new ideas to improve medical imaging. The proposed AR application will help doctors and radiologists in their daily basis. Still most doctors, surgeons, and radiologists use two-dimensional (2D) slices to visualize patients’, which is quite hard to image and map the 3D structure of a human anatomical structure with just 2D plain images. This process requires a lot of experience which sometimes might not be enough. It will help physicians by visualizing patients’ scans such as Computed Tomography (CT) or Magnetic Resonance Imaging (MRI) to be rendered as a three-dimensional (3D) object and not as a 2D object. Using the AR technology makes it much more straightforward in observing the rendered object. The proposed application reads a medical image file(s) such as CT or MRI files and renders its data as a 3D model in real world space, by using a volume rendering technique called ray-tracing. This technique works by reading data from a selected file or dataset. After reading a file, the technique traces a ray into object space from each pixel. Afterwards, it accumulates and calculates the color and opacity values of pixels along each ray. The Final step is to assign the values to its corresponding pixels. By completing this process, a selected dataset is rendered as a 3D object into real world space. With AR technology, seeing and interacting with the 3D object is much easier for the users. The expected outcomes of this study are to improve the process of pre-surgery medical images visualization. With interactive buttons and controllers included in the application and the use of several options like decreasing opacity, clipping, zooming, rotation, threshold … etc. will give more control to the users. Moreover, the proposed application enables users to customize his views to get the best of the 3D object for better visualization. This study discusses the in development mobile AR application that could be used as a new, more facilitating method of visualizing medical images. The application will deliver a more feasible way of interacting with visualized medical images, with buttons and sliders and virtual joysticks creating a better user experience (UX).

Update Method of Cost Function to Learn Robust Policy Parameters

Because robotic experiments are often expensive in time and/or money, it is a common idea to use simulations instead of real robot experiments to have a robot acquire a motion through reinforcement learning. However, simulation models inevitably have some modeling errors, because of which the solution can be an inappropriate one for the real robot. As a solution to this problem, additional learning processes will be performed using the real robot in many studies, but for some robots and tasks, it will be difficult or infeasible. Therefore, learning methods that can find a robust solution without real robot experiments are desirable. This paper proposes a novel method to update the cost function so that the minimization of the cost will lead to a robust solution, only using simulations. As the method only modifies the cost, the convergence to a solution will not be a problem, unlike the existing method that is based on a similar idea. The validity of the idea is tested by simulations.
Point matching algorithm based on machine learning method

Point matching is an important issue of computer vision and pattern recognition, and it is widely used in target recognition, medical image, pose estimation, etc. In this study, we propose a novel end-to-end model (multi-pointer network) based on machine learning method to solve this problem. We capitalize on the idea of multi-label classification to ameliorate the pointer network. Instead of outputting a member of input sequence, our model selects a set of input elements as output. Considering matching problem as a sequential manner, our model takes the coordinates of points as input and outputs correspondences directly. Using this new method, we can effectively solve the translation of the whole space and other large-scale rigid transformations. Furthermore, experiment results show that our model can be generalized to other combinatorial optimization problems in which the output is a subset of input, like Delaunay triangulation.
Software development documenting – documentation types and standards

Due to the rapid development of various software products, applications and information systems developed for government and commercial sectors as well as for common users there is the need to write a large amount of technical documentation describing the created product from various perspectives.The reasons for such documentation -«internal» and «external» ones are presented in this paper.The types of documentation: requirements documentation (defines the expectations for the software, including functional requirements, hardware requirements, compatibility and limitations); architecture documentation (defines the high-level architecture of the system: the components, their functions and the data and control flow); technical documentation (written for technical audience, describing the code, algorithms and interface); user manuals (there are several types of user documentation: tutorial, how-to guide and reference guide); marketing documentation are described.Documentation standards (free and paid) are given as well.
A Research on the Detection of Fog Visibility

The existing video visibility algorithm uses the apparent brightness of the target object from the image acquisition instead of the inherent brightness of the target object, which affects the accuracy of the visibility detection. Therefore, this paper designs a new visibility detection algorithm, which based on the digital camera response curve fitting. Experimental pictures are taken on the uniformity white diffuse surface with a fixed aperture, different exposure time. The average gray value of the pictures are calculated using the middle part of the experimental pictures. The double logarithmic curve is fitted of the pixel value of the image and exposure time. Then according to this curve, the value $$ \upgamma $$ can be obtained, which is the conversion coefficient between the brightness and inherent brightness. The atmospheric extinction coefficient can be calculated by the inherent brightness, resulting in atmospheric visibility values. The algorithm chooses the pavement as a marker to solve the problem that the target is not easy to find on the road. The distance between the target point and the camera is calculated by the inherent lane mark line and the camera self-calibration method. Experimental results show that the proposed visibility detection algorithm has high accuracy and low cost. It is very suitable for the fog visibility monitoring on the high speed road.
Cryptocurrencies: Some Remarks from the Perspective of Polish Employment and Tax Law

Abstract In view of the fact that technological progress is in a constant state of change, current research efforts are directed towards blockchain technology and cryptocurrencies. Starting with the description of the way blockchain technology operates, the notions of decentralisation, proof-of-work consensus, and practical immutability are explained. Further, the article examines the possibility of using cryptocurrency in order to pay remuneration, realise partial non-cash payment of remuneration or grant an award to an employee. This article presents evidence that demonstrates that remuneration in the framework of the employment relationship in Poland cannot be paid in cryptocurrency, which contributes to the performance of the protective function of labour law. The article concludes that a collective labour agreement could include a clause allowing the employer to realise partial non-cash payment of remuneration in cryptocurrency. Similar provisions could be introduced in labour law, but the Polish legislator has never adopted such a measure. The authors highlight, however, that an award can be paid in cryptocurrency even in the full amount. Next, the authors research the new tax regulations in force in Poland since 1 January 2019 and explain why it is conceptually more convincing to classify revenues from cryptocurrency trading as revenues from money capital and revenues from capital gains than as property rights. The article presents a definition of the disposal for valuable consideration of a virtual currency. The purpose of this article is also to study how high is the income tax on income earned from the disposal for valuable consideration of virtual currencies. Moreover, an overview of the legislation related to tax-deductible expenses is provided. Finally, some reflections on the cryptocurrency trading in the context of the pursuit of an economic activity are given. The review especially highlights the Council Directive 2006/112/EC of 28 November 2006 on the common system of value added tax, and the judgment of the CJEU of 22 October 2015 ( Skatteverket v. David Hedqvist [2015], case C-264/14), which has impacted the approach to the VAT problem in Poland.
