标准模型下可托管的基于身份认证密钥协商
Escrowable Identity-Based Authenticated Key Agreement in the Standard Model
摘要
Abstract
In recent years,a few escrowable ID-AKA protocols have been proposed,but none of them are provably secure in the standard model while simultaneously having strong security.The main issue is how a simulator is able to deal with reveal-queries without the help of random oracles.In this paper,we presented a method incorporating a built-in security trapdoor function in an es-crowable ID-AKA protocol.The security of our protocol relied on the hardness of the decisional Bilinear Diffie-Hellman Inversion problem.Meanwhile,we extended the security game of ID-AKA protocols to resist stronger adversarial powers,which allowed our security game to capture additional security properties such as perfect forward secrecy,ephemeral secrets reveal resistance and so on.Assuming that no adversary can obtain the master secret key and each party in the protocol has at least one uncompromised se-cret,our scheme is secure.关键词
