Research On Distribution CRL Combined With Routing Mechanism For Ad Hoc Network

A mobile Ad Hoc network is a new-style mobile multi-hop wireless network which has many different characters from traditional wireless network. They connect networks and send data by self-organizing and self-managing, without the help of the infrastructure, such as base stations or access points.Introducing PKI (Public-Key Infrastructure) security system into the framework of the Ad Hoc network can resist tampering, forgery, eavesdropping and other network attacks, and improve the security of the network. On this basis, this paper make deeply research on and CRL (Certificate Revocation List), and describe the Ad Hoc Network regular routing protocols. Then the distribution scheme of CRL combined with routing mechanism is given: CRL is multicast by the LDAP (Lightweight Directory Access Protocol) server in the form of periodic release. If some terminals separately request CRL table or delta to the LDAP server, unicast transmission is used, and route discovery is similar to what multicast do.Experimental data show that: the system can achieve the security to store CRL and meet the user's query and downloading the CRL, which reach the requirements of the designed system.
