This paper continues the study of password-based protocols for authenticated key exchange (AKE). In 2000, Bellare, Pointcheval, and Rogaway proposed the formal model on AKE. In this paper, we propose new security notions on AKE, based on the non-malleability of session keys. Then we prove that those security notion are equivalent. Furthermore, we show that there is a protocol secure in the random...

In this paper, we propose a scheme of an aggregate signature which has additional functionality allowing any holder of a signature to designate the signature to any desired designated-verifier.
