摘　　要：提出了一个基于身份的多消息多接收者的签密算法,新算法可同时为多个接收者对多个消息进行签密。根据此特点,提出了适用于Ad Hoc网络的基于多接收者签密算法的门限密钥更新协议,并对新算法和协议进行了分析。分析表明,该算法具备机密性和可认证性,且具有较高的性能;密钥更新协议不但具备算法的特性,而且还可以抵抗共谋攻击。An ID-based multi-message and multi-receiver signcryption algorithm was proposed,which could simultaneously signcrypt lots of messages for lots of receivers.Based on it,a threshold rekeying protocol was proposed to be applied in Ad Hoc networks,and the new algorithm and protocol were analyzed.The analysis indicates that the algorithm achieves authenticity and confidentiality while being of high efficiency,and that the rekeying protocol not only possesses the characteristics of the mentioned algorithm,but also can resist collusion attacks.
