摘　　要：为了解决船舶自组网应用条件下的消息认证问题,利用门限代理签名体制和双线性对性质,设计了一种不依赖于可信认证中心和防篡改设备的签名方案。通过双重代理密钥的设计和门限签名机制的应用,使船舶节点通过多项式时间的计算完成消息签名,并运用随机预言模型证明了方案的安全性。分析表明,该方案在保证正确性的前提下能满足强代理签名的性质,并具有较低的计算开销和通信开销。In order to solve the problem of message authentication under the conditions of the ship ad-hoc network(SANET),a signature scheme that does not depend on trusted certificate authorities and tamper-proof devices(TPD)was proposed by using the threshold proxy signature scheme and the properties of bilinear pairings.The proposed scheme used the dual-proxy key and the threshold signature mechanism to enable the ship nodes calculate the message signature in polynomial time.Moreover,the security of the scheme was also proved under the random oracle model.The performance analysis results show that the proposed scheme can meet the requirement of strong proxy signature under the premise of guaranteeing correctness,and has lower computational cost and communication cost.
