A Chosen Ciphertext Attack on a Public Key Cryptosystem Based on Lyndon Words

Ludovic Perret

Abstract

In this paper, we present a chosen ciphertext attack against a public key cryptosysten based on Lyndon words \cite{sm}. We show that, provided that an adversary has access to a decryption oracle, a key equivalent to the secret key can be constructed efficiently, i.e. in linear time.
