Summary:
We review some of the recent work on chaos-based cryptography. We argue that if a chaotic map f is used in cryptography, then it should be implemented as a bijection FM : D → D, where D is a finite set with cardinality M, such that, for large M, FM ‘approximates well’ the chaotic map f . Several examples, including chaotic block cypher and chaotic public-key encryption algorithm, are given.
