基于身份的Ad Hoc网络门限密钥发送协议

目前已提出的多个基于身份的密钥发送协议,由于Ad Hoc网络的特性现有协议都不适用.针对这一问题,提出了一个基于身份的Ad Hoc网络门限密钥发送协议,采用门限秘密共享技术实现系统私钥的分布式生成,并且利用盲签名机制有效地实现了通过公开信道进行密钥的安全发送.本协议中任何网络节点不能假冒用户去获得用户私钥,而且能够抵抗重放攻击、中间人攻击和内部攻击,适宜在Ad Hoc网络中使用.

Identity-based threshold key issuing protocol for Ad Hoc networks

Key issuing protocol is an important issue in identity-based cryptography. At present there are some key issuing protocols in ID-based cryptography;but those protocols are not applied due to the properties of the Ad Hoc networks.An identity-based threshold key issuing protocol is proposed for Ad Hoc networks, in which secret sharing is deployed to realize the distributed generation of the system's private key;and it makes use of the blind signature to ensure the secure issuing of the private keys of nodes in public channel. In proposed protocol, neither node can impersonate the users to obtain the private keys and is secure against replay, man-in-the-middle and insider attacks;and it suits for Ad Hoc networks.
