Store and sSearch of trust evidence in MANET

Trust based security control and resource schedule are an emerging research direction, providing powerful closed loop control compared with traditional mechanisms based on static parameters. Trust relations are built based on some evidences produced by the previous interactions among entities which involve a protocol. However, the crucial challenges are coming to make trust evaluation in the scenario of mobile ad hoc networks, which forms spontaneous formation of a network of nodes without infrastructure. In this paper, we focus on the issues of storing and searching trust evidences in MANET, aiming at improving security and decreasing cost.
