On complete one-way functions

On complete one-way functions Complete constructions play an important role in theoretical computer science. However, in cryptography complete constructions have so far been either absent or purely theoretical. In 2003, L.A. Levin presented the idea of a combinatorial complete one-way function. In this paper, we present two new one-way functions based on semi-Thue string rewriting systems and a version of the Post correspondence problem. We also present the properties of a combinatorial problem that allow a complete one-way function to be based on this problem. The paper also gives an alternative proof of Levin’s result. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Problems of Information Transmission Springer Journals

Abstract

Complete constructions play an important role in theoretical computer science. However, in cryptography complete constructions have so far been either absent or purely theoretical. In 2003, L.A. Levin presented the idea of a combinatorial complete one-way function. In this paper, we present two new one-way functions based on semi-Thue string rewriting systems and a version of the Post correspondence problem. We also present the properties of a combinatorial problem that allow a complete one-way function to be based on this problem. The paper also gives an alternative proof of Levin’s result.
