Chameleon hash function based on SM3 and its applications
网络与信息安全学报The immutability of blockchain technology was known to ensure that once data was added to the chain, it could not be altered, which meant that any harmful information uploaded would continue to exert serious negative impacts. To ensure that on-chain data

Cryptographic Hash Functions in Groups and Provable Properties
, 2011 We consider several "provably secure" hash functions that compute simple sums in a well chosen group (G,*). Security properties of such functions provably translate in a natural way to computational problems in G that are simple to define and possibly also hard to solve.

Sarmal: A cryptographic hash function
, 2020 Recent years witnessed the continuous works on analysis of cryptographic hash functions which reveal that most of them are not as secure as claimed. Wang et al. presented the first full round collisions on MD4 and RIPEMD using a new attack technique on hash functions which is based on differential cryptanalysis.

Analysis of cryptographic hash functions
, 2012 The National Institute of Standards and Technology (NIST) launched in 2008 a public competition, called the SHA-3 competition, aiming at definining a new standard for hash functions. We study here the algebraic properties of some of the candidates to this contest. Among the functions analyzed, is the Keccak algorithm, which was recently announced to be
