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.
