abstract = "The design of non-cryptographic hash functions by
means of evolutionary computation is a relatively new
and unexplored problem. In this paper, we use the
Genetic Programming paradigm to evolve collision free
and fast hash functions. For achieving robustness
against collision we use a fitness function based on a
non-linearity concept, producing evolved hashes with a
good degree of Avalanche Effect. The other main issue,
efficiency, is assured by using only very fast
operators (both in hardware and software) and by
limiting the number of nodes. Using this approach, we
have created a new hash function, which we call
gp-hash, that is able to outperform a set of five
human-generated, widely-used hash functions.",
