Abstract

One way hash functions are a major tool in cryptography. DES is the best known and most widely used encryption function in the commercial world today. Generating a one-way hash function which is secure if DES is a "good" block cipher would therefore be useful. We show three such functions which are secure if DES is a good random block cipher.
