### Paper: Pitfalls in public key cryptosystems based on free partially commutative monoids and groups

Authors: Maria Isabel Gonzalez Vasco Rainer Steinwandt URL: http://eprint.iacr.org/2004/012 Search ePrint Search Google At INDOCRYPT 2003 Abisha, Thomas, and Subramanian proposed two public key schemes based on word problems in free partially commutative monoids and groups. We show that both proposals are vulnerable to chosen ciphertext attacks, and thus in the present form must be considered as insecure.
