摘要：Cryptographic hash functions (CHF) represent a
core cryptographic primitive. They have application in digital
signature and message authentication protocols. Their main
building block are Boolean functions. Those functions provide
pseudo-randomness and sensitivity to the input. They also help
prevent and lower the risk of attacks targeted at CHF. Cellular
automata (CA) are a class of Boolean functions that exhibit good
cryptographic properties and display a chaotic behavior. In this
article, a new hash function based on CA is proposed. A
description of the algorithm and the security measures to
increase the robustness of the construction are presented. A
security analysis against generic and dedicated attacks is
included. It shows that the hashing algorithm has good security
features and meet the security requirements of a good hashing
scheme. The results of the tests and the properties of the CA used
demonstrate the good statistical and cryptographic properties of
the hash function.
