Abstract: Mobile Ad Hoc networks, composed of mobile wireless nodes, are particularly vulnerable due to their features of open medium and dynamically changing topology. Trust management is the scheme for building trust between nodes in mobile Ad Hoc networks and it is the security base of mobile Ad Hoc network. The state of the art in trust management of mobile Ad Hoc networks was surveyed. Firstly, the characteristics of trust relationship in mobile Ad Hoc network and different types of trust management in mobile Ad Hoc network were analyzed. Secondly, some typical trust management schemes were reviewed. A comparison and discussion of their respective merits and faults was made at the same time. Finally, the challenges worthy of further research in this area were presented.
