New Two-Party Identity-based Authenticated Key Agreement Protocol without Random Oracles

摘要：

Design of identity-based key agreement protocols which are efficient and provably secure withoutrandom oracles (in the standard model) is suitable for applications. Based on Waters identity-based encryption scheme, we propose a new identity-based authenticated key agreement protocol, which can be used in either escrowed or escrow-less mode. The security is proven without random oracles and rests on the hardness of the decisional Bilinear Diffie-Hellman problem. Compared by the known protocols that are secure without random oracles, the performance is similar with respect to computational and communication efficiencies. Moreover, the protocol used in escrowless mode is secure against a malicious private key generator.
