摘要
提出了对HORSE算法的改进算法HORSEI2.与HORSE相比,HORSEI2在不失去相同安全强度的前提下降低了签名验证的计算复杂性和签名传输的通信负荷.在此基础上,还提出了一个新的具备安全功能的Ad hoc网络满足多QoS约束的按需距离向量(AODV)路由协议SAODVQOS,它采用HORSEI2作为密码机制为路由报文签名.理论分析表明SAODVQOS协议机制为AODVQOS协议增加了源认证机制,从而为Ad hoc网络节点提供了来源真实性、数据完整性和抗否认等安全服务以抵御恶意节点的攻击.基于NS2的仿真结果表明SAODVQOS网络性能良好.
An improved algorithm HORSEI2 was proposed based on HORSE.Compared with HORSE,HORSEI2 reduced the computational complexity of verifying a signature and the communication overhead caused by transmitting the signature without drop in security.After that,a novel secure quality of service for Ad hoc on-demand distance vector(AODV) routing protocol SAODVQOS was presented using HORSEI2 as cryptographic mechanism to sign the route massages.The analyses of theory on SAODVQOS indicate that the novel protocol enhance...
