Name systems provide easy communication in large networks and relieve the network users and administrators from remembering long network addresses. But mobility, limited lifetime of user nodes and dynamic situations of MANETs make it impossible to use conventional NAME systems such as DNS on these kinds of networks. Numerous name systems are designed and proposed for MANETs, but most of these system are insecure and do not provide secure name services for upper layers. Name resolution is one of the main operations of that are conduct by client nodes to achieve the requested bindings from name systems. Vulnerability of MANETs to various security attacks, make it clear the need for a secure and reliable name resolution to protect the users against different security threats. In this paper, we present a solution to provide users with secure binding information that can use for secure name resolution. This solution is not dependent on any name systems and can be used with any previously designed naming scheme to enhance the security of name resolution even in offline state and link failures.
