Mobile Ad-hoc NETwork (MANET) endures wide number of security issues in discovering services. Furthermore, different services require different level of security. In this paper, a trust based security mechanism for service discovery in MANET is proposed. This mechanism computes confidence or trust value for each node considering its interaction and behavior in the network. The trust model designates different protection level for services. Based on this protection level of the services, secure communication is offered. Further, the secure communication channel is established among nodes by sharing secret keys. By simulation results, the authors show that the proposed mechanism provides better security against attacks with reduced packet drops.
