摘要： 着重研究了无线自组网络上基于身份的密码体制的密钥生成问题,设计了一个分布式的密钥生成协议。该协议不需要预先分发任何秘密信息,不需要假设用户间存在安全信道和可信第三方,在设定系统参数后,自组网络的各站点运行该协议,就可以安全有效地生成与自己身份相对应的用户私钥,从而有效地使用基于身份的密码体制实现自组网络内部的端到端认证和保密通信。

Abstract: This paper proposes distributed protocols to solve the problem for identity-based(ID-based) cryptography.The protocols do not assume any prior distribution of keys,security channels,or trusted third party.With the protocols and some proper parameters,every station in the ad-hoc network can efficiently compute his own private keys for ID-based cryptography mechanisms,so as to apply them to provide end-to-end authenticityand confidentiality.
