Practical Algebraic Attack on DAGS [PDF]
, 2019 DAGS scheme is a key encapsulation mechanism (KEM) based on quasi-dyadic alternant codes that was submitted to NIST standardization process for a quantum resistant public key algorithm. Recently an algebraic attack was devised by Barelli and Couvreur (Asiacrypt 2018) that efficiently recovers the private key.

Revisiting the Computation Analysis against Internal Encodings in White-Box Implementations
Transactions on Cryptographic Hardware and Embedded Systems, 2023 White-box implementations aim to prevent the key extraction of the cryptographic algorithm even if the attacker has full access to the execution environment. To obfuscate the round functions, Chow et al.

Entropy, 2015 Since Advanced Encryption Standard (AES) in stream modes, such as counter (CTR), output feedback (OFB) and cipher feedback (CFB), can meet most industrial requirements, the range of applications for dedicated stream ciphers is decreasing.

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.

Algebraic Side-Channel Attacks [PDF]
, 2010 In 2002, algebraic attacks using overdefined systems of equations have been proposed as a potentially very powerful cryptanalysis technique against block ciphers. However, although a number of convincing experiments have been performed against certain reduced algorithms, it is not clear whether these attacks can be successfully applied in general and ...

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".

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

Searching for an Efficient System of Equations Defining the AES Sbox for the QUBO Problem
Journal of Telecommunications and Information Technology, 2023 The time complexity of solving the QUBO problem depends mainly on the number of logical variables in the problem. This paper focuses mainly on finding a system of equations that uniquely defines the Sbox of the AES cipher and simultaneously allows us to
