Engineering Breakdown Probability Profile for PDP and DCR Optimization in a SPAD Fabricated in a Standard 55nm BCD Process
Edoardo Charbon, Claudio Bruschini, Ekin Kizilkan, Pouyan Keshavarzian, Francesco Gramuglia, Myung Jae Lee
CMOS Single-Photon Avalanche Diodes (SPADs) have broken into the mainstream by enabling the adoption of imaging, timing, and security technologies in a variety of applications within the consumer, medical and industrial domains. The continued scaling of te ...
2021QAIR: Practical Query-efficient Black-Box Attacks for Image Retrieval
Shaokai Ye, Yuan He, Hang Su, Jinfeng Li
We study the query-based attack against image retrieval to evaluate its robustness against adversarial examples under the black-box setting, where the adversary only has query access to the top-1 ranked unlabeled images from the database. Compared with que ...
IEEE COMPUTER SOC2021Time-Synchronization Attacks against Critical Infrastructures and their Mitigation
Marguerite Marie Nathalie Delcourt
This work focuses on the security of critical infrastructures against time-synchronization attacks (TSA). A TSA can impact any network that relies on the dynamic analysis of data, by altering the time synchronization between its nodes. Such attacked networ ...
EPFL2021Integrity and Metadata Protection in Data Retrieval
Secure retrieval of data requires integrity, confidentially, transparency, and metadata-privacy of the process. Existing protection mechanisms, however, provide only partially these properties: encryption schemes still expose cleartext metadata, protocols ...
EPFL2021Towards a secure and trustworthy imaging with non-fungible tokens
Touradj Ebrahimi, Evgeniy Upenik, Davi Nachtigall Lazzarotto
Non fungible tokens (NFTs) are used to define the ownership of digital assets. More recently, there has been a surge of platforms to auction digital art as well as other digital assets in form of image, video, and audio content of all sorts. Although NFTs ...
2021Malware in the SGX supply chain: Be careful when signing enclaves!
Rafael Pereira Pires, Pascal Felber
Malware attacks are a significant part of the new software security threats detected each year. Intel Software Guard Extensions (SGX) are a set of hardware instructions introduced by Intel in their recent lines of processors that are intended to provide a ...
2020A Distributed Cyber-Attack Detection Scheme With Application to DC Microgrids
Giancarlo Ferrari Trecate, Mustafa Sahin Turan
DC microgrids often present a hierarchical control architecture, requiring integration of communication layers. This leads to the possibility of malicious attackers disrupting the overall system. Motivated by this application, in this article, we present a ...
2020X-Attack: Remote Activation of Satisfiability Don’t-Care Hardware Trojans on Shared FPGAs
Mirjana Stojilovic, Dina Gamaleldin Ahmed Shawky Mahmoud, Wei Hu
Albeit very appealing, FPGA multitenancy in the cloud computing environment is currently on hold due to a number of recently discovered vulnerabilities to side-channel attacks and covert communication. In this work, we successfully demonstrate a new attack ...
2020Symmetric Asynchronous Ratcheted Communication with Associated Data
Following up mass surveillance and privacy issues, modern secure communication protocols now seek strong security, such as forward secrecy and post-compromise security, in the face of state exposures. To address this problem, ratcheting was thereby introdu ...
Springer, Cham2020Security-aware Routing and Scheduling for Control Applications on Ethernet TSN Networks
Today, it is common knowledge in the cyber-physical systems domain that the tight interaction between the cyber and physical elements provides the possibility of substantially improving the performance of these systems that is otherwise impossible. On the ...
