Abstract

When downloading software from websites located somewhere on the globe, doubt is in place on authenticity and integrity of the software obtained. Fortunately, cryptologic experience has shown that concepts based on digitally signed message digests can ensure integrity and authenticity in web-based software distribution applications. It is the purpose of this contribution to introduce a novel approach for generating secure hash values (message digests) computed from input data dependent pseudo-random permutations. Essentially, input messages are processed sequentially using bytes of input data as keys to discrete chaotic Kolmogorov systems which permute an initial message digest in a cryptographically strong manner heavily depending on the input stream.
