摘要：

Most available identity-based authenticated key agreement protocols require that both protocol participants are from the same PKG(Private Key Generator) environment. However, safe communication is requisite between protocol participants that are from different PKG environment in practice. In this paper, a new identity-based AKA (Authenticated Key Agreement) protocol is proposed in multiple PKG environment, which makes use of a new technique called twin Diffie-Hellman problem. Moreover, the security of the proposed protocol can be reduced to the standard CDH and BDH assumption in the eCK model, which makes use of the trapdoor test" technology proposed by Cash et al in Eurocrypt 2008."
