Ad hoc网络中一种基于身份的可度量分布式信任模型方案的探析

Ad hoc网络是一种新型无线移动网络，由于无线链路的不可靠性和拓扑结构的多变性等原因，它面临着许多安全挑战。本文设计了一种基于身份的可度量分布式信任模型方案，将密钥管理和认证与信任评估机制有机地结合起来。密钥管理是信任评估的基础，信任评估机制又为密钥管理的正确实施提供了有效的判别和补充，从而有效保证了系统的私密钥不被恶意节点利用和攻击。

A Study of the Ad hoc Networks Which is an Identity-based Measurable Distributed Trust Model Program

Mobile ad hoc network（MANET） is a new type of wireless mobile network. While MANET is faced to various security challenges because of many factors, such as the unreliable character of wireless link and the variability of topology. In this paper, an identity-based measurable distributed trust model program has been designed, which is combined the key management with authentication and trust evaluation mechanisms organically. And the key management is the foundation of the trust evaluation, meanwhile the trust evaluation mechanism provides effective identification and complement for the correct implementation of the key management. In that case, the system could be effectively guaranteed that the private key not to be used and attacked by malicious nodes.
