We introduce the concept of attribute-based authenticated key exchange (AB-AKE) within the framework of ciphertext policy attribute-based systems. A notion of AKE-security for AB-A...

Abstract. Algorithmic progress and future technology threaten today’s cryptographic protocols. Long-term secure protocols should not even in future reveal more information to aâ€...
Abstract— Converting a secure group key agreement protocol into password-based setting is not a trivial task. The security of a password-based scheme hinges on preventing diction...
Video-on-demand (VOD) is a very promising multimedia application of the near future. In order for such a service to be commercially viable, efficient storage and retrieval schemes...
Abstract. Recently we showed how to justify a Dolev-Yao type model of cryptography as used in virtually all automated protocol provers under active attacks and in arbitrary protoco...
