Cryptanalysis of the Chor-Rivest cryptosystem

Serge Vaudenay
1998
Conference paper
Abstract

Knapsack-based cryptosystems used to be popular in the beginning of public key cryptography before being all broken, all but the Chor-Rivest cryptosystem. We show how to break this one with its suggested parameters: GF(p24) and GF(25625). We also give direction on possible extensions of our attack.
