Hardware Trojan Detection Technique Using Frequency Characteristic Analysis of Path Delay in Application Specific Integrated Circuits
Authors: Tran Ha Thai , Hoang Phuc Van , Do Tuan Ngoc , Nguyen Duong Hai
Published: November 2021

Abstract—  Since the last decade, hardware Trojan (HT) have become a serious problem for hardware security because of outsourcing trends in Integrated Circuit (IC) manufacturing. As the fabrication of IC is becoming very complex and costly, more and more chipmakers outsource their designs or parts of the fabrication process. This trend opens a loophole in hardware security, as an untrusted company could perform malicious modifications to the golden circuit at design or fabrication stages. Therefore, assessing risks and proposing solutions to detect HT are very important tasks. This paper presents a technique for detecting HT using frequency characteristic analysis of path delay. The results show that measuring with the frequency step of 0.016 MHz can detect a HT having the size of 0.2% of the original design.Tóm tắt— Từ thập niên 2010, Trojan phần cứng (HT) đã trở thành một vấn đề nghiêm trọng đối với bảo mật phần cứng, do xu hướng thuê sản xuất mạch tích hợp (Integrated Circuit - IC). Khi quá trình chế tạo IC trở nên phức tạp và tốn kém, ngày càng nhiều nhà sản xuất chip lựa chọn phương án thuê lại một phần hoặc toàn bộ thiết kế IC. Xu hướng này tạo ra lỗ hổng trong bảo mật phần cứng, vì một công ty không đáng tin cậy có thể thực hiện các sửa đổi độc hại vào trong mạch nguyên bản ở giai đoạn thiết kế hoặc chế tạo. Do đó, đánh giá rủi ro và đề xuất giải pháp phát hiện HT là một trong những nhiệm vụ hết sức quan trọng. Bài báo này trình bày một giải pháp phát hiện HT sử dụng phân tích đặc tính tần số của độ trễ đường truyền tín hiệu. Kết quả cho thấy, thực hiện khảo sát với bước tần số 0,016 MHz có thể phát hiện được HT có kích thước 0,2% so với thiết kế ban đầu.

Published: November 2021

Abstract—   Computer keyboards are often used to enter data for a computer system, data could be normal information or confidential information such as password, key. Keyboards use electronic components so they will generate electromagnetic radiation that can reveal information. This article presents the acquisition of electromagnetic emanating from the PS/2 keyboards through different paths (in space, through power line or via LAN cable). After acquisition we develop a program on MATLAB to recover the keystroke signal from data which is obtained in the near field of PS/2 keyboard. The result of this side channel attack is recovered an average of more than 70% of the keystrokes in near field of PS/2 keyboards.  Our best attack can recover up to more than 90% of the keystrokes. From this result, we conclude that PS/2 keyboards generate electromagnetic radiations which can cause the loss of information and they are not safe to use when entering confidential information. Tóm tắt—   Bàn phím máy tính thường được sử dụng để nhập dữ liệu đầu vào cho một hệ thống máy tính, các dữ liệu có thể là văn bản thông thường hoặc thông tin cần được bảo mật như mật khẩu hay khóa.

A Novel Points of Interest Selection Method For SVM-based Profiled Attacks
Authors: Quy Tran Ngoc , Quang Nguyen Hong
Published: November 2021

Abstract—Currently, one of the most powerful side channel attacks (SCA) is profiled attack. Machine learning algorithms, for example support vector machine (SVM), are currently used to improve the effectiveness of the attack. One issue of using SVM-based profiled attack is extracting points of interest (POIs), or features from power traces. Our work proposes a novel method for POIs selection of power traces based on the combining variational mode decomposition (VMD) and Gram-Schmidt orthogonalization (GSO). VMD is used to decompose the power traces into sub-signals (modes) and POIs selection process based on GSO is conducted on these sub-signals. As a result, the selected POIs are used for SVM classifier to conduct profiled attack. This attack method outperforms other profiled attacks in the same attack scenario. Experiments were performed on a trace data set collected from the Atmega8515 smart card with AES-128 run on the Sakura-G/W side channel evaluation board and the DPA Contest v4 dataset to verify the effectiveness of our method in reducing number of power traces for the attacks, especially with noisy power traces.Tóm tắt—Hiện nay, tấn công mẫu được xem là một trong những tấn công kênh kề (SCA) mạnh. Các thuật toán học máy, ví dụ như máy vector hỗ trợ (SVM), thường được sử dụng để nâng cao hiệu quả của tấn công mẫu. Một thách thức đối với tấn công mẫu sử dụng SVM là cần phải tìm được các điểm thích hợp (POI) hay các đặc trưng từ vết điện năng tiêu thụ. Công trình nghiên cứu này đề xuất một phương pháp mới đề tìm POI của vết điện năng tiêu thụ bằng cách kết hợp kỹ thuật phân tích mode biến phân (VMD) và quá trình trực giao hóa Gram-Schmidt (GSO). Trong đó, VMD được sử dụng để phân tách vết điện năng tiêu thụ thành các tín hiệu con còn gọi là VMD mode và việc lựa chọn POIs trên VMD mode này được thực hiện dựa trên quá trình GSO. Dựa trên phương pháp lựa chọn POIs này, chúng tôi đề xuất phương pháp tấn công mẫu sử dụng SVM có hiệu quả tốt hơn các tấn công mẫu khác ở cùng kịch bản tấn công. Các thí nghiệm tấn công được thực hiện trên tập dữ liệu được thu thập từ thẻ thông minh Atmega8515 cài đặt AES-128 chạy trên nền tảng thiết bị tấn công kênh kề Sakura-G/W và tập dữ liệu DPA Contest v4, để chứng minh tính hiệu quả của phương pháp của chúng tôi, trong việc giảm số lượng vết điện năng tiêu thụ cần cho cuộc tấn công, đặc biệt trong trường hợp các điện năng tiêu thụ có nhiễu.

Some results on new statistical randomness tests based on length of runs
Authors: Linh Hoàng Đình
Published: November 2021

Abstract— Random Sequences and random numbers play a very important role in cryptography. In symmetric cryptography primitives, a secret key is the most important component to ensure their security. While cryptographic protocols or digital signature schemes are also strongly dependent on random values. In addition, one of the criteria for evaluating security for cryptographic primitives such as block cipher, hash function... is to evaluate the output randomness. Therefore, the assessment of randomness according to statistical tests is really important for measuring the security of cryptographic algorithms. In this paper, we present some research results on randomness tests based on the length of runs proposed by A. Doğanaksoy et al in 2015. First, we show that some probability values for tests based on lengths 1 and 2 are inaccurate and suggest editing. Secondly, we have given and demonstrated for the general case the runs of any length k. Finally, we built a randomness testing tool and applied evaluations to true random sourcesTóm tắt— Các dãy và các số ngẫu nhiên đóng một vai trò rất quan trọng trong mật mã. Trong các nguyên thuỷ mật mã đối xứng, khoá bí mật chính là thành phần quan trọng nhất nhằm đảm bảo tính an toàn của chúng. Trong khi đó, các giao thức mật mã hay lược đồ chữ ký số cũng phụ thuộc nhiều vào các giá trị ngẫu nhiên. Ngoài ra, một trong các tiêu chí để đánh giá tính an toàn cho các nguyên thuỷ mật mã như mã khối, hàm băm… là đánh giá tính ngẫu nhiên đầu ra. Do đó, việc đánh giá tính ngẫu nhiên theo các kiểm tra thống kê thực sự rất quan trọng đối với việc đánh giá tính an toàn của các thuật toán mật mã. Trong bài báo này, chúng tôi trình bày một số kết quả nghiên cứu về các tiêu chuẩn kiểm tra loạt dựa trên độ dài đã được đề xuất bởi A. Doğanaksoy cùng đồng sự năm 2015. Đầu tiên, chúng tôi chỉ ra rằng một số giá trị xác suất cho các loạt độ dài 1 và 2 là chưa chính xác và đề xuất chỉnh sửa. Sau đó, chúng tôi đã đưa ra và chứng minh cho trường hợp tổng quát các loạt có độ dài kbất kỳ. Cuối cùng, chúng tôi đã xây dựng một công cụ kiểm tra tính ngẫu nhiên dựa trên độ dàicác loạt và áp dụng đánh giá cho các nguồn ngẫu nhiên thực sự.

Published: November 2021

Abstract— The Layer 2 network security has shown many advantages compared to Layer 3. However, the structure of Layer 2 does not indicate the size of data packet, it makes the difficult to capture the data packet, especially in the case the packet is captured by hardware. Also, there are limitation of using software to capture the packet. In addition, when the size of the packet is not defined, it will be difficult to handle the packet with inserting cryptographic parameters that exceed the permissible length. In this paper, a technical solution for capturing Ethernet packet directly from FPGA is presented, organising data to ensure transparent communication capability to implement Layer 2 packet security, to overcome the limitations when capturing packet by using software.Tóm tắt— Bảo mật mạng Layer 2 đã thể hiện được nhiều ưu điểm so với bảo mật Layer 3, tuy nhiên do cấu trúc của gói tin Layer 2 không cho biết kích thước gói tin nên gây khó khăn cho việc bắt gói tin, đặc biệt khi bắt trực tiếp bằng phần cứng, trong khi nếu sử dụng phần mềm thì có nhiều hạn chế. Hơn nữa, khi không biết kích thước sẽ gây khó khăn trong việc xử lý gói tin khi chèn các tham số mật mã vượt quá độ dài cho phép. Trong bài này trình bày một giải pháp kỹ thuật bắt gói tin Ethernet trực tiếp từ FPGA, tổ chức dữ liệu đảm bảo khả năng truyền tin trong suốt cho phép thực hiện bảo mật gói tin Layer 2, khắc phục được những hạn chế khi bắt gói tin bằng phần mềm.

Artists Depicting Balchik.The Seaside City as a Source of Inspiration for the Bulgarian Artists from the Twentieth Century
Authors:   National Art Academy, Bulgaria, Basseva Silviya
Published: November 2021

The immense interest that architecture has on bulgarian artists justifies its place among our paintings. One of the prime locations, which inspired artists to draw architecture is Balchik. By following the compositions, inspired by our seaside town, we can discover representatives of all the generations of bulgarian artists, including some of the most renowned names. The inextinguishable interest in Balchik is a phenomenon in itself. The dispersed combination of vegetation in an urban environment, along with the close proximity of the sea, gives many opportunities for establishing artistic goals, determined by the nature and attitude of the individual painter. The picturesque nook of Bulgaria provokes creativity and leads to diverse artistic achievements. As a result, we possess a qualitative and various arrangements of art pieces, which give a strong foundation for assessment and artistic analysis. The development of landscapes with a Balchik-inspired subject throughout the years is demonstrative of the improvement of painting in Bulgaria, including some of the most influential and original bulgarian artists.

Article deals with some personal visual research during motion on the line of mind and time. The author rides a bicycle and led the discussion in a particular direction from personal experiences to common insights for art and life. The bicycle is an individual means of transport. There are many meanings in the definition of “individual” – the choice of a bicycle is based on the height of the bike, the terrain to which it will be used, the BEAUTY of the frame and the components of the extra equipment. Apart from the utilitarian, the bicycle has an aesthetic and ecological importance for the people. He also has an emotional presence.
“Everyone has their own reality”. “Realism” – topicality in the East and in the West at the end of the 1950s and the 1960s
Authors:   BAS, Bulgaria, Genova Irina
Published: November 2021

In the decade up to 1968, “realism” was a key ideological notion on both sides of the Iron Curtain. It was not unambiguous; it expressed misunderstandings and contradictions, and gave room for manipulative interpretations and diversion of meanings. The visions of “reality” and “realism” were often conflicting in national artistic milieus, as was the case in France. The Neo-avant-garde communities did not stay away from the dispute over the notion and Pierre Restany even appropriated it by using it to name the art group which he unified as an ideologist in 1960. The complex dynamics of the ideas in “the opponents’ field” was closely followed both in the East and the West. At international art forums the notion of “realism” played a role in different critical discourses. The opposing ideologies, through mediation and transfer, mutually modelled both its use by critics and the art practices themselves.
Signs of Non-Objectivity in Bulgarian Sculpture
Authors:   University of Architecture, Civil Eng. and Geodesy, Bulgaria, Nikolchev Ilko
Published: November 2021

The non-objective work of art is unrelated to real-world objects. The essence of non-objective art is that the work completes in the mind of the viewer, and he creates his own interpretation. In this sense, the viewer is involved in the creative process and interacts with the work of art. The expressive means and techniques of nonobjective sculpture are at the heart of some of the most avant-garde art movements, such as minimalism, land-art, site-specific art and environmental art. Some examples of non-objective sculpture flow from symposium sculpture, which later evolves into urban spaces. The first international symposiums, where Bulgarian authors work with their foreign colleagues and get acquainted with various artistic practices, influence the Bulgarian sculpture. The non-objective sculpture has its manifestations in Bulgarian art, though later. The works of some Bulgarian authors play an important role in the changes in the Bulgarian sculpture and in the integration into the world processes.
Art and Еsthesis. Ontologization and deontologization of the sensations
Authors:   ", Totlyakov Atanas ,   St. Cyril and Methodius",   University of Veliko Tarnovo
Published: November 2021

This article discusses the problem of overcoming the stereotypical patterns imposed by the aesthetics of modernity. The idea of separating an interdisciplinary field of knowledge, including science and artistic practice, is defended. Interdisciplinary connections are based on the sensory study of being and the immediate exploitation of the sensations and sensory sensations of the human body, interpreted as a kind of artistic material in an extended (multisensory) field. Equality of all sensory channels in the creative act is upheld, including the tactility, smell, taste neglected by aesthetics.
The Emancipation of the Intermediary. The Other Reality of the Architectural Form in the Work of Peter Eisenman
Authors:   National Art Academy, Bulgaria, Danailov Anton
Published: November 2021

The report examines the work of the American architect Peter Eisenman (b. 1932), focusing on his critical approach, presented as a process of emancipation from the conventional grounds and relationships, defining the architectural form. The creative searches of Eisenman are represented by some of his landmark architectural projects, and considered also in the context of the critical controversy, which it causes. The development, although dedicated to a theme relating to a particular practice in architecture, sheds light on a wider discourse around the idea of the form and its self-reflection in the plastic arts.
Untimely Reasoning about Two Monuments. Between Architecture, Sculpture and Site
Authors:   National Art Academy, Bulgaria, Danailov Anton
Published: November 2021

The report compares the form-formation principles, key to the architecture of the Wexner Center for the Visual Arts (1983/89) Columbus, Ohio – of the American Peter Eisenmann – with some of the techniques used in the spatial – compositional solution of the destroyed Sofia monument “1300 Years Bulgaria” (1980/81–2017). The text refers to the 80’s of the twentieth century and the creative approaches, distinctive for some of the lastest „large-scale monuments“ realized in Bulgaria. These approaches are considered in the light of one opened architectural theory, absolutely oppositional to the one typical to our country at this time. The comparison aims to are to expand, within this date, the scope of the spatial-artistic analysis, committed to the relationship between the architecture, sculpture and the surrounding environment.
The Black Scuare – from Alle to Malevich
Authors:   National Art Academy, Bulgaria, Gyoshev Alexander
Published: November 2021

The study observes some of the most important details hidden in Kazimir Malevich’s abstract painting “Black Square on a White Background” (1915). Of central concern for the more adequate understanding of this intriguing piece of art is the tracking of its supposed relationship with the work of Alfons Alle – French writer known for his extravagant style and ideas. The differences between Alle’s painting entitled “Negroes Fighting in a Cellar at Night” and Malevich’s composition, both sharing similar themes, are analyzed in their specific historical and cultural context. Finally, there is a hypothesis about “Black Square on a White Background” as a work marked with a psychological projection that unfolds itself through the dark figure of the square, as an iconic image that still has an impact on the contemporary art and may serve as a key to some symbols of the present.
Interaction between the Viewer and Object of Minimalism
Authors:   University of Architecture, Civil Eng. and Geodesy, Bulgaria, Nikolchev Ilko
Published: November 2021

With the emergence of abstract art, the process of communication between the work and the viewer changes. The artists take advantage of other means of expression to influence the viewer’s mind. They are of a new nature; they are the carriers of new visual and social messages. The minimalists strive to break down the traditional notions of art and to eliminate the differences between painting and sculpture by focusing on creating three-dimensional objects. The meaning of the object is not essential, but the essence is the interaction of the viewer with the object. There is a new emphasis on the physical space in which the works are located. This is the reason to investigate these processes. The text analyzes the main features of minimalism, distinguishing them from the previous trends in visual arts. The theoretical and practical contributions of some of the founding authors of this movement, such as Frank Stella, Robert Morris, Donald Judd, Dan Flavin, Richard Serra and their signature works characterized by the viewer’s inclusion in the space of the site. Researchers of minimalism, highlighting the research problem, subject of the article, are quoted.

Some of the most impressive architectural masterpieces of the past, such as the Cologne Cathedral or the Cathedral in Milan, have taken several centuries for their creation and have involved thousands of people. Today, a glossy office building in Dubai has been built or rather printed in just 17 days, with 29 workers involved. Three-dimensional printing has been identified as the Fourth Industrial Revolution and is increasingly replacing traditional construction methods. There is no doubt that 3D printing will affect the design and production of buildings. Does the fact that 3D printing can be used means that it should replace analog with digital construction?
Les Icônes Miraculeuses du Monastère de Zographe
Authors:   ", Dontchev Georges ,   St. Cyril and Methodius",   University of Veliko Tarnovo
Published: November 2021

Parmi l’énorme héritage d’icônes du monastère de Zographe du Mont Athos, en Grèce, ses icônes miraculeuses sont d’une importance spiratuelle, historique et culturelle non seulment pour monastère de Zographe et le Mont Athos, mais d’une façon générale pour la Chrétienneté Orthodoxe. Elles présentent un intêret non seulment du point de vue culture, estétique et d’histoire d’art, mais sont en même temps un centre d’atraction de pèlerinage et de vénération d’un grand nombre de pèlerins bulgares et de tout le monde orthodoxe. Quand on parle d’icônes miraculeuses, il faut souligner que toute icône en son essence est miraculeuse à une condition bien sûr, que l’on ait une foi assez forte, pour le constater. Il y a des icônes que l’on définit comme miraculeuses à cause du fait qu’il en coulent des larmes, du sang ou d’huiles saintes. D’autre part, l’épithète “miraculeuse” est atribuée aux icônes, liées aux récits où d’une manière inéxplicable elles répondent aux prières des fidels, les guérissent, les sauvent, viennent les aider, mais d’une façon inimitable et qui échappe à la logique humaine. Un nombre impressionnant d’icônes miraculeuses se trouvent dans les monastères du Mont Athos. Elles sont d’une grande importancennon non seulment dans l’histoire des monastères à travers les siècles, mais certaines jouent un rôle important décisif dans le service religieux de tous les jours. D’autres encore, ont un rôle prépondérant dans la foundation et le nom du monastère. Dans le monastère de Zographe il y a six grandes icônes miraculeuses. Trois d’entre elles sont consacrées à St. Georges et trois à la Vierge. Les icônes de St. Georges sont: St. Georges Acheiropoiitos, St. Georges de l’Arabie et St. Georges de Moldàvie. Les icônes de la Vierge sont: St. Vierge Proagellomeni, St. Vierge Epakoousa et St. Vierge Esfagmeni. L’icône la plus vénérée et la plus importante est cette de St. Georges Acheiropoiitos. D’après la légende c’est l’autoportrait de St. Georges lui-même, ce qui explique le nom de monastère Zographe, ce qui en grec signifie “peintre”. Elle présente un très grand intérêt avec ses qualités artistiques au même titre que l’autre icône de St. Georges de l’Arabie. Cette dernière icône de son côté est a double face et présente un grand intérêt avec la très rare representation de St. Archange Michel à cheval.

The article deals with the scenes of “Torture of Sinners” in Blagoevgrad churches: “St. Elijah” in the village of Selishte, “St. Dimitar” in the village of Palat, “Nativity of the Virgin Mary” in the village of Velyushtets and “St. St. Constantine and Helena” in the village of Krustiltsi. These temples were painted by the later representatives of the Bansko Art School Mihalko Golev and Dimitar Sirleshtov and their assistants in the last decades of the XIX and the first decade of the XX century.

Projection of the Imaginary
Authors:   ", Spassov Radko ,   St. Cyril and Methodius",   University of Veliko Tarnovo
Published: November 2021

This is a concept related to the creation of a mental image at speculative space below surface of the picture plane. As non-representational and incompatible with it, the radical idea is might be defined as conscious infinite extension of three-dimensional field in which the matter exist. As a matter of fact it is evocation of space that is not void, but consists of multifold speculative creations from a myriad of perspectives. As a result appears a flat abstract image elicited on the picture plane. This projection breaking through the surface and reveals the essence of the imaginary objects without distortions. As a visible expression the metaphoric image preserves the identity of the things in their difference.

The Aspect of “Time” in an Artistic Work (on Selected Examples of Polish Conceptual Art, Own Work and Student Works)
Authors:   Akademia Sztuk Pięknych im. Władysława Strzemińskiego, Łodz, Polska, Chrzanowski Artur
Published: November 2021

Attempting to visualize concept of “time” has a great tradition in contemporary art, in particular in conceptual art in the 20th century. The starting point for that consideration are conceptual activities in Polish contemporary art and their influence on the didactic program of teaching photography – the topics and selections taken for the visual structure of the work. Discussion on the example of selected works of Polish conceptual art of the 20th century, including the effects of the didactic process of the Photography and Multimedia Activities Studio that I run at the Academy of Fine Arts in Łódź. As a part of research and didactic observations, for many years students have been given the task of creating a visual work that shows the passage of time. The selection of photographic pictures and the method of working should be treated as an attempt to create a personal commentary on the surrounding reality. Students are choosing a theme, planning and recording over for a long period of time, for example a few weeks or months, the natural variability of the motif with particular emphasis on the type of light resulting from the time of day and the environment. The collections are presented in the form of a slide show, and the rhythm of the appearing photographs can be variable, consciously used as an additional artistic element. In the initial phase, the students discuss the selected issue and chosen artistic convention, while the technique and artistic form are free. In my own artistic work, too, the aspect of the “time” is an important factor. In many art works and art projects it is an important semantic element. Years later, I return to the same themes or places to reinterpret them and relate to the past. It concerns both the topic, issues and the composition of the visual implementation. Examples of artistic projects implemented over many years are cycles regarding the identity of the home city, for example “Postcards from Łódź”, “genius_lodzi” or “The Origin”.
