Popis:	In this paper, we propose a new keyed one-way double-block-length hash function by using Non-linear Cellular Automata (CA), named as NCASH. The structure of NCASH mainly follows the Wide-Pipe construction, which is a modified Merkle Damgard construction along with the concept of Hirose double-block-length one-way compression function. Our design exploits the random evolution of the CA, as well as a simple regular structure to construct the compression function. The analysis shows that NCASH family is secure against the related known attacks.
