An Ultra-High Throughput AES-Based Authenticated Encryption Scheme for 6G: Design and Implementation
Andrea Felice Caforio, Subhadeep Banik
In this paper, we propose Rocca-S, an authenticated encryption scheme with a 256-bit key and a 256-bit tag targeting 6G applications bootstrapped from AES. Rocca-S achieves an encryption/decryption speed of more than 200 Gbps in the latest software environ ...
Springer International Publishing Ag2024Analyzing and Protecting Communication Metadata
Most communication systems (e.g., e-mails, instant messengers, VPNs) use encryption to prevent third parties from learning sensitive information.However, encrypted communications protect the contents but often leak metadata: the amount of data sent and the ...
EPFL2021Secrecy by Design With Applications to Privacy and Compression
Secrecy by design is examined as an approach to information-theoretic secrecy. The main idea behind this approach is to design an information processing system from the ground up to be perfectly secure with respect to an explicit secrecy constraint. The pr ...
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, Cham2020Exact Preimages of Neural Network Aircraft Collision Avoidance Systems
François Fleuret, Kyle Michael Matoba
A common pattern of progress in engineering has seen deep neural networks displacing human-designed logic. There are many advantages to this approach, divorcing decisionmaking from human oversight and intuition has costs as well. One is that deep neural ne ...
2020Building Security Protocols Against Powerful Adversaries
As our sensitive data is increasingly carried over the Internet and stored remotely, security in communications becomes a fundamental requirement. Yet, today's security practices are designed around assumptions the validity of which is being challenged. In ...
EPFL2016Clever Arbiters Versus Malicious Adversaries
When moving from known-input security to chosen-input security, some generic attacks sometimes become possible and must be discarded by a specific set of rules in the threat model. Similarly, common practices consist of fixing security systems, once an exp ...
Springer Berlin Heidelberg2016Signature Schemes Secure Against Hard-to-Invert Leakage
Side-channel attacks allow the adversary to gain partial knowledge of the secret key when cryptographic protocols are implemented in real-world hardware. The goal of leakage resilient cryptography is to design cryptosystems that withstand such attacks. In ...
Springer2016Boosting OMD for Almost Free Authentication of Associated Data
Serge Vaudenay, Damian Vizár, Reza Reyhanitabar
We propose pure OMD (p-OMD) as a new variant of the Offset Merkle-Damgård (OMD) authenticated encryption scheme. Our new scheme inherits all desirable security features of OMD while having a more compact structure and providing higher efficiency. The origi ...
Springer2015OMD: A Compression Function Mode of Operation for Authenticated Encryption
Serge Vaudenay, Damian Vizár, Reza Reyhanitabar
We propose the Offset Merkle-Damgård (OMD) scheme, a mode of operation to use a compression function for building a nonce-based authenticated encryption with associated data. In OMD, the parts responsible for privacy and authenticity are tightly coupled to ...
