Trust-Based Distributed Authentication Method for Collision Attack Avoidance in VANETs
IEEE Access, 2018 A vehicular ad hoc network (VANET) is a collection of mobile vehicles that aids roadside communication through vehicle-to-vehicle and vehicle-to-infrastructure operation modes.

Efficient Collision Search Attacks on SHA-0 [PDF]
, 2005 In this paper, we present new techniques for collision search in the hash function SHA-0. Using the new techniques, we can find collisions of the full 80-step SHA-0 with complexity less than 239 hash operations.

Cache-Collision Timing Attacks Against AES
, 2006 This paper describes several novel timing attacks against the common table-driven software implementation of the AES cipher. We define a general attack strategy using a simplified model of the cache to predict timing variation due to cache-collisions in the sequence of lookups performed by the encryption.

SHA-256 Collision Attack with Programmatic SAT
Cryptographic hash functions play a crucial role in ensuring data security, generating fixed-length hashes from variable-length inputs. The hash function SHA-256 is trusted for data security due to its resilience after over twenty years of intense ...

New hash function based on C-MD structure and chaotic neural network
网络与信息安全学报, 2023 In recent years, widely used hash algorithms such as MD5 and SHA-1 have been found to have varying degrees of security risks.The iterative structure of the SHA-2 algorithm is similar to that of SHA-1, making it vulnerable to attacks as well.Meanwhile ...

Revisit two memoryless state‐recovery cryptanalysis methods on A5/1
IET Information Security, 2023 At ASIACRYPT 2019, Zhang proposed a near collision attack on A5/1 claiming to recover the 64‐bit A5/1 state with a time complexity around 232 cipher ticks with negligible memory requirements.

NMPC-Based Cooperative Strategy For A Target Pair To Lure Two Attackers Into Collision [PDF]
IEEE Control Systems Letters, vol. 7, pp. 496-501, 2023, 2021 This paper presents a cooperative target defense strategy using nonlinear model-predictive control (NMPC) framework for a two--targets two--attackers (2T2A) game. The 2T2A game consists of two attackers and two targets. Each attacker needs to capture a designated target individually.

IACR Transactions on Symmetric Cryptology, 2020 Fast Near collision attacks on the stream ciphers Grain v1 and A5/1 were presented at Eurocrypt 2018 and Asiacrypt 2019 respectively. They use the fact that the entire internal state can be split into two parts so that the second part can be recovered from the first one which can be found using the keystream prefix and some guesses of the key materials.
