摘要：Mobile AdHoc Network (MANET) endures wide number of security issues in discovering services. Furthermore, different services require different level of security. For instance commercial applications necessitate less security compare to military applications. Thus, evolving an efficient service discovery mechanism in view of above criteria is a complicated work. 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, we show that the proposed mechanism provide better security against attacks with reduced packet drops.
