摘要
在探究无线移动Adhoc网络中以门限机制为基础的分布式CA安全认证机制的优势与缺陷的基础上,分析研究了整合身份与门限机制的分布式无线移动Ad-hoc网络密钥管理模型。该模型以基于身份的加密签名机制为基础,结合基于Lagrange插值的门限秘密共享方案,适应于无线移动Ad-hoc网络环境中拓扑变化、资源有限等特点,可以实现安全高效的无线移动Ad-hoc网络认证系统。
Traditional security authentication mechanism such as PKI is no longer applicable to Mobile Ad-hoc NETwork (MANET), and therefore the distributed CA based on threshold secret sharing mechanism is introduced into MANET. After discussion of the distributed CA's advantages and disadvantages, A detail analyses is given to a MANET distributed key management model integrated both identity cryptography and threshold mechanism based on Lagrange interpolation. The analysis shows that the model is capable to realize a wonderful MANET security authentication system with high efficiency.
