Side-channel analysis of isogeny-based key encapsulation mechanisms and hash-based digital signatures
Current cryptographic solutions will become obsolete with the arrival of large-scale universal quantum computers. As a result, the National Institute of Standards and Technology supervises a post-quantum standardization process which involves evaluating ca ...
EPFL2024Power Yoga: Variable-Stretch Security of CCM for Energy-Efficient Lightweight IoT
Damian Vizár, Reza Reyhanitabar, Emiljano Gjiriti
The currently ongoing NIST LWC project aims at identifying new standardization targets for lightweight authenticated encryption with associated data (AEAD) and (optionally) lightweight cryptographic hashing. NIST has deemed it important for performance and ...
RUHR-UNIV BOCHUM, HORST GORTZ INST IT-SICHERHEIT2021Orthros: A Low-Latency PRF
We present Orthros, a 128-bit block pseudorandom function. It is designed with primary focus on latency of fully unrolled circuits. For this purpose, we adopt a parallel structure comprising two keyed permutations. The round function of each permutation is ...

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 ...
2020Tweaking 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, Cham2020Beyond Conventional Security in Sponge-Based Authenticated Encryption Modes
The Sponge function is known to achieve 2c/2 security, where c is its capacity. This bound was carried over to its keyed variants, such as SpongeWrap, to achieve a min{2c/2,2 kappa} security bound, with kappa the key length. Similarly, many CAESAR competit ...
SPRINGER2019Provably Secure Authenticated Encryption
Authenticated Encryption (AE) is a symmetric key cryptographic primitive that ensures confidentiality and authenticity of processed messages at the same time. The research
of AE as a primitive in its own right started in 2000.
The security goals of AE wer ...
