Provably Secure Identity-based Authenticated Key Agreement Protocols in Multiple PKG Environment

摘要

摘要: 目前大多数基于身份认证密钥协商协议需要参与协议双方在同一个PKG环境下，而实际应用中需要在不同PKG环境下的用户之间也能进行安全通信。该文结合twin Diffie-Hellman问题提出了一个全新的不同PKG环境下的基于身份认证密钥协商协议。利用Cash等人在2008年欧密会上提出的trapdoor test技术在eCK模型中将新协议的安全性规约到标准的CDH和BDH 假设。

Abstract: 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.
