Clone resistant mutual authentication using two broadcast encryption

Sun-nam Lee; Hak-soo Ju; Bong-seon Kim

This paper provides a clone resistant mutual authentication between Secure Digital (SD) memory cards and host devices. The existing mutual authentication using one broadcast encryption can not resist cloning attacks. Therefore, a new clone resistant mutual authentication is proposed by using two broadcast encryption with the traitor tracing algorithm.
