This book is to design, implement, test and cryptanalyze three stream ciphers that are based on the multi-map orbit hopping mechanism (Mmohom), a generic method to design stream ciphers. Mmohocc, multi-map orbit hopping chaotic cipher: chaos has been connected to cryptography due to its confusion and diffusion, the two important properties of a secure cipher. We apply Mmohom to multiple chaotic systems to construct Mmohocc, which greatly accelerates chaos behavior and makes chaos more suitable for cryptographic purposes. The keystreams have passed two batteries of the most popular and...
