P2P network has been widely used because of advantages such as efficient use of network bandwidth, saving of computing resources, and quick information exchange. In particular, the infra that manages each nodes centrally in P2P network does not exist and each node is a structure performing the sender and receiver roles. The service applying P2P technique in MANET is increased because this structure is very similar to the structure of MANET. However, the reliability may be lower by providing an erroneous service from malicious nodes because the supervision of management for nodes participating in P2P does not perform. In this paper, we propose hybrid trust evaluation technique based on Trust Zone structure to improve the reliability between nodes. TZM node is elected for trust evaluation of member nodes internal each TrustZone. The certificate of member nodes is issued in the elected TZM and the information is stored in TZMT. The data transmission of malicious nodes is blocked by limiting the data transmission of nodes that do not issued the certificate. The reputation-based trust management technique was applied to perform the fair file transmission of nodes and block the behavior of selfish nodes. The excellent performance of the proposed technique in this paper was confirmed through experiments.
