DFAulted: Analyzing and Exploiting CPU Software Faults Caused by FPGA-Driven Undervolting Attacks
Mirjana Stojilovic, Dina Gamaleldin Ahmed Shawky Mahmoud, David Dervishi
Field-programmable gate arrays (FPGAs) combine hardware reconfigurability with a high degree of parallelism. Consequently, FPGAs offer performance gains and power savings for many applications. A recent trend has been to leverage the hardware versatility o ...
2022Six shades lighter: a bit-serial implementation of the AES family
Subhadeep Banik, Muhammed Fatih Balli, Sergio Roldán Lombardía
Recently, cryptographic literature has seen new block cipher designs such as PRESENT, GIFT or SKINNY that aim to be more lightweight than the current standard, i.e., AES. Even though AES family of block ciphers were designed two decades ago, they still rem ...
2021Tweaking Key-Alternating Feistel Block Ciphers
Tweakable block cipher as a cryptographic primitive has found wide applications in disk encryption, authenticated encryption mode and message authentication code, etc. One popular approach of designing tweakable block ciphers is to tweak the generic constr ...
Springer, Cham2020The Area-Latency Symbiosis: Towards Improved Serial Encryption Circuits
Andrea Felice Caforio, Subhadeep Banik, Muhammed Fatih Balli
The bit-sliding paper of Jean et al. (CHES 2017) showed that the smallest-size circuit for SPN based block ciphers such as AES, SKINNY and PRESENT can be achieved via bit-serial implementations. Their technique decreases the bit size of the datapath and na ...
2020Bidirectional Asynchronous Ratcheted Key Agreement with Linear Complexity
Serge Vaudenay, Fatma Betül Durak
Following up mass surveillance and privacy issues, modern secure communication protocols now seek more security such as forward secrecy and post-compromise security. They cannot rely on an assumption such as synchronization, predictable sender/receiver rol ...
