Original Kurzfassung:
Cryptographic hash functions are security primitives that
compute check sums of messages in a strong manner and this way are
of fundamental importance for ensuring integrity and authenticity in
secure communications. However, recent developments in cryptanalysis
indicate that conventional approaches to the design of cryptographic
hash functions may have some shortcomings.
Therefore it is the intention of this contribution to propose a novel way
how to design cryptographic hash functions. Our approach is based on
the idea that the hash value of a message is computed as a messagedependent
permutation generated by very special chaotic permutation
systems, so called Kolomogorov systems. Following this systems theoretic
approach we obtain arguably strong hash functions with the additional
useful property of excellent scalability.
