一种新的域间基于身份认证密钥协商协议

目前对于密钥交换协议的研究越来越多,如基于Diffie-Hellman的密钥交换协议。但是对于密钥的认证却没有很好地解决,如何保证参与方的认证？例如在Diffie-Hellman密钥交换协议中,如何防止中间人攻击。目前的方案需要可信的第三方TTP（Trusted Third Party）的支持;密钥的更新和管理有困难,不同的域无法完成密钥交换。现提出一种新的域间基于身份认证的密钥交换协议,一方面使得在不同域间的用户也可以交换密钥;另一方面用户使用基于身份的密钥产生方案可以对用户进行认证。

New Inter-Domain Identity-based Authenticated Key Agreement Protocol

At present, more and more search of secrete key exchange Hellman key exchange. But a key agreement protocol that does not provide ble to man - in - the - middle attack, e.g. , but, a trusted third party is required in the Diffie -Hellman key exchange. have been proposed, such as Diffie- authentication of the parties is vulnera- Some protocols -have been presented; schemes. It is difficult to update or manage the secrete key if in different domains, the secrete key cannot be completed. A new inter- domain identity based authenticated key exchange protocol is proposed. Users in different domains can exchange the key; besides user authenticate other user with key generated by identity based scheme.
