IEEE Access, 2022 In this paper, we propose and evaluate a method for generating key-dependent feedback configurations (KDFC) for $\sigma $ -LFSRs. $\sigma $ -LFSRs with such configurations can be applied to any stream cipher that uses a word-based LFSR.

Yoneda Hacking: The Algebra of Attacker Actions
ACM Transactions on Cyber-Physical Systems, 2022 Our work focuses on modeling the security of systems from their component-level designs. Towards this goal, we develop a categorical formalism to model attacker actions. Equipping the categorical formalism with algebras produces two interesting results for security modeling.

Algebraic and Slide Attacks on KeeLoq [PDF]
, 2008 KeeLoq is a block cipher used in wireless devices that unlock the doors and alarms in cars manufactured by Chrysler, Daewoo, Fiat, GM, Honda, Jaguar, Toyota, Volvo, Volkswagen, etc [8,9,33,34]. KeeLoq is inexpensive to implement and economical in gate count, yet according to Microchip [33] it should have "a level of security comparable to DES".

A generic operational metatheory for algebraic effects [PDF]
, 2010 We provide a syntactic analysis of contextual preorder and equivalence for a polymorphic programming language with effects. Our approach applies uniformly across a range of algebraic effects, and incorporates, as instances: errors, input/output, global ...

Algebraic Attacks on Summation Generators [PDF]
, 2004 We apply the algebraic attacks on stream ciphers with memories to the summation generator. For a summation generator that uses n LFSRs, an algebraic equation relating the key stream bits and LFSR output bits can be made to be of degree less than or equal to \(^{\lceil\log_2 n \rceil}\) using ⌈log2 n ⌉ + 1 consecutive key stream bits. This is much lower

Possibility of decryption speed-up by parallel processing in CCA secure hashed ElGamal.
PLoS ONE, 2023 In order to prove the ElGamal CCA(Chosen Ciphertext Attack) security in the random oracle model, it is necessary to use the group where ICDH(Interactive Computational Diffie Hellman) assumption holds. Until now, only bilinear group with complex algebraic
