We present a provably secure tree based authenticated group key agreement protocol in dynamic scenario. Bilinear pairing and multi-signature are at the heart of our protocol. We p...
—A key agreement protocol is a protocol whereby two or more communicating parties can agree on a key or exchange information over an open communication network in such a way that...
We investigate a number of issues related to identity based authenticated key agreement protocols using the Weil or Tate pairings. These issues include how to make protocols effici...
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...
In this paper a `fair' key generation and certification protocol for Diffie-Hellman keys is proposed, which is intended for use in cases where neither User nor CA are trusted...
