基于快速公钥签名的自组网QoS多播路由认证

提出了一个新的具备安全功能的Ad hoc网多QoS约束的多播路由协议NSQMRAN。该协议采用新型公钥签名算法NTRUSign作为密码机制为路由报文签名，加强了安全性。NSQMRAN为Ad hoc网QoS多播路由协议增加了源认证机制，从而提供了QoS多播路由报文的来源真实性、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，在Ad hoc网中，与采用RSA公钥算法的协议相比，采用NTRUSign的NSQMRAN协议网络性能较好，产生较少的端到端延迟。

QoS Multicast Routing Authentication for Ad Hoc Networks Based on Fast Signing with Public Key

A novel secure multiple QoS guaranteed multicast routing protocol for Ad hoc networks NSQMRAN is presented, which uses NTRUSign as cryptographic mechanism to sign the route massages. NSQMRAN enhances the security with source authentication mechanism and provides such security services as reality, integrity and non-repudiation for the QoS multicast route messages in Ad hoc networks to guard against the attacks caused by malicious nodes. And the main simulating on results based on NS2 shows that compared with other protocols which use RSA as public key cryptographic algorithm, the performance of NSQMRAN protocol based on NTRUSign is better and it causes less delay of end to end.
