    Encryption AXI Transaction Core for Enhanced FPGA Security

    Get PDF
    The current hot topic in cyber-security is not constrained to software layers. As attacks on electronic circuits have become more usual and dangerous, hardening digital System-on-Chips has become crucial. This article presents a novel electronic core to encrypt and decrypt data between two digital modules through an Advanced eXtensible Interface (AXI) connection. The core is compatible with AXI and is based on a Trivium stream cipher. Its implementation has been tested on a Zynq platform. The core prevents unauthorized data extraction by encrypting data on the fly. In addition, it takes up a small area—242 LUTs—and, as the core’s AXI to AXI path is fully combinational, it does not interfere with the system’s overall performance, with a maximum AXI clock frequency of 175 MHz.This work has been supported within the fund for research groups of the Basque university system IT1440-22 by the Department of Education and within the PILAR ZE-2020/00022 and COMMUTE ZE-2021/00931 projects by the Hazitek program, both of the Basque Government, the latter also by the Ministerio de Ciencia e Innovación of Spain through the Centro para el Desarrollo Tecnológico Industrial (CDTI) within the project IDI-20201264 and IDI-20220543 and through the Fondo Europeo de Desarrollo Regional 2014–2020 (FEDER funds)

    “Legal Form and Legal Legitimacy: The IHRA Definition of Antisemitism as a Case Study in Censored Speech”

    The challenge posed by legal indeterminacy to legal legitimacy has generally been considered from points of view internal to the law and its application. But what becomes of legal legitimacy when the legal status of a given norm is itself a matter of contestation? This article, the first extended scholarly treatment of the International Holocaust Remembrance Alliance (IHRA)’s new definition of antisemitism, pursues this question by examining recent applications of the IHRA definition within the UK following its adoption by the British government in 2016. Instead of focusing on this definition’s substantive content, I show how the document reaches beyond its self-described status as a “non-legally binding working definition” and comes to function as what I call a quasi-law, in which capacity it exercises the de facto authority of the law, without having acquired legal legitimacy. Broadly, this work elucidates the role of speech codes in restricting freedom of expression within liberal states

    B.O.G.G.L.E.S.: Boundary Optical GeoGraphic Lidar Environment System

    Get PDF
    The purpose of this paper is to describe a pseudo X-ray vision system that pairs a Lidar scanner with a visualization device. The system as a whole is referred to as B.O.G.G.L.E.S. There are several key factors that went into the development of this system and the background information and design approach are thoroughly described. B.O.G.G.L.E.S functionality is depicted through the use of design constraints and the analysis of test results. Additionally, many possible developments for B.O.G.G.L.E.S are proposed in the paper. This indicates that there are various avenues of improvement for this project that could be implemented in the future
