Abstract :
Using commutative cryptosystems is a way to obtain efficient mental poker protocols which do not require using a trusted third party (TTP). However, the security of such protocols depends on the particular cryptosystem used. We show that a TTP-free mental poker protocol using an ElGamal-like commutative cryptosystem is insecure.
