摘　　要：针对移动自组网(MANET)信任数据存储分散和获取困难的问题,提出一种信任数据自存储模型.采用数字签名技术保证信任数据的真实性和完整性,并提出相应的协议,确保节点诚实存储其信任数据,防止节点不存储较差的评价.探讨针对本模型的攻击方法,包括否认、伪造和篡改.采用GNY逻辑,间接证明所提出协议的安全性.在存在恶意节点的MANET环境下进行实验仿真,结果表明:该模型占用网络带宽较少,具有良好的收敛性,并能够较好地保证信任数据的准确度.A self-arehiving model of trust data was proposed to solve the problem of distributed trust data storage and retrieval difficulty in mobile ad hoe network （MANET）. Digital signature technology was used to ensure the authenticity and integrity of trust data. And corresponding protocols were proposed to ensure that nodes can store its own trust data honestly, avoiding the behavior that nodes do not store poor trust data. Several attack methods aimed at this model were discussed, including negation, forgery and manipulation. Furthermore, GNY logic system indirectly demonstrated that the proposed protocol was secure. Finally, simulation was carried out in MANET with the existence of malicious nodes. The results indicated that the proposed model takes up less network bandwidth, gives good convergence and can ensure trust data accuracy.
