A Secure Authenticated Key Agreement Protocol for Application at Digital Certificat (original) (raw)

To establish secure channel for network communication in open and distributed environments, authenticated key agreement protocol is an important primitive for establishing session key. So far, a great deals of identity-based protocols have been proposed to provide secure mutual authentication and common session key establishment in two-party setting for secure communications in the open environment. Majority of the existing authenticated key agreement protocols only provide partial forward secrecy. Therefore, such protocols are unsuitable for real-world applications that require a stronger sense of perfect forward secrecy. In this paper, we present a secure twoparty identity-based authenticated key agreement protocol with achieves most of the required security attributes. We also show that the scheme achieves the security attributes include known-key secrecy, perfect forward secrecy, PKG forward secrecy, key-compromise impersonation resilience, unknown key-share resilience, no key r...
