Near Collision Attack Against Grain V1
Daniel Patrick Collins, Subhadeep Banik, Willi Meier
A near collision attack against the Grain v1 stream cipher was proposed by Zhang et al. in Eurocrypt 18. The attack uses the fact that two internal states of the stream cipher with very low hamming distance between them, produce similar keystream sequences ...
2023Zero-Knowledge IOPs with Linear-Time Prover and Polylogarithmic-Time Verifier
Interactive oracle proofs (IOPs) are a multi-round generalization of probabilistically checkable proofs that play a fundamental role in the construction of efficient cryptographic proofs. We present an IOP that simultaneously achieves the properties of zer ...
SPRINGER INTERNATIONAL PUBLISHING AG2022Tweaking 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, Cham2020Bidirectional 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 ...
