(Quantum) Collision Attacks on Reduced Simpira v2
IACR Transactions on Symmetric Cryptology, 2021 Simpira v2 is an AES-based permutation proposed by Gueron and Mouha at ASIACRYPT 2016. In this paper, we build an improved MILP model to count the differential and linear active Sboxes for Simpira v2, which achieves tighter bounds of the minimum number ...

Optimizing Fast Near Collision Attack on Grain Using Linear Programming [PDF]
IEEE Access, 2019 In 2018, an attack named fast-near-collision attack (FNCA) was proposed, which is an improved version of near-collision attack (NCA) on Grain-v1, one of the three hardware-oriented finalists of the eSTREAM project.

Horizontal Collision Correlation Attack on Elliptic Curves [PDF]
, 2014 Elliptic curves based algorithms are nowadays widely spread among embedded systems. They indeed have the double advantage of providing efficient implementations with short certificates and of being relatively easy to secure against side-channel attacks.

Random Plaintext Collision Attack Against AES Algorithm with Reused Masks [PDF]
Jisuanji gongcheng, 2022 The topic of side-channel attacks is popular in cryptographic research. As an important branch of side-channel attacks, collision attacks can effectively extract information related to intermediate values from energy leakage.

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 ...
