短签名技术与安全匿名源路由S2ASR设计

摘要

提出一种改进的、无需可信第三方的数字短签名技术,解决了无线自组织网络的密钥委托问题,理论分析表明:该签名能够有效抵抗各种伪造攻击,提高了通信安全和执行效率;基于改进的短签名技术和双线性映射陷门构造方案,实现了源目节点的强匿名和双向认证,无需PKG在线支持,减小了通信延时,提高了网络扩展性.%The paper provides an improved digital short signature technology without the trustworthy third party, avoids the key commission on MANET. A serial of analysis indicate that it can counteract availably all kinds of attacks of forgery sign, and enhances sign efficiency and communication security. Furthermore, the paper gives bilinear map trapdoor scheme for route messages, and realizes strong anonymity and two way authentications between the source and target nodes based on short signature and bilinear map trapdoor scheme, decreases network delay without real-time trustworthy third party and provides the extensibility for networks.
