Development of the Hash Function Using Modified Skew Tent Map to Improve Blockchain Technology

Ibn Al-Haitham Journal for Pure and Applied Sciences
Using SHA256 in the Blockchain system for security purposes, as it is important in linking blocks and preventing tampering efficiently and securely. In order to further confirm the security of SHA256 and protect it and increase its susceptibility to ...

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.

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.

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
