In this paper, we present a novel wireless authentication protocol
with providing mobile users anonymity and untraceability. Our scheme
is based on smart card and public key cryptosystems, and mobile users
only do hash operation and symmetric decryption. In our protocol,
mobile users change their passwords freely and securely without the
help of the corresponding home network or the visited network, while
also providing secure mutual authentication. The most significant
feature is that provides perfect confidentiality to mobile user's
identity and the session keys even though the secret parameters in
smart card have been leaked completely. Finally, the performance
of our scheme is analyzed.
