Security Strategy of MANET Based on Identity-Based Cryptosystems

Mobile Ad hoc Network (MANET for short) is a new type of wireless network. It is a self-configurable and autonomous network which consists of several independent nodes, and is different from the traditional wireless network because its characteristic of non-central administration. Those nodes participate with each other to share the network responsibilities. (t, n) threshold secret-shared cryptosystems, Identity-Based cryptosystems and session key between the nodes are used in this paper to provide a new but safe strategy for Mobile Ad hoc Network. Under the premise of network communication efficiency, the information in common communication channel is well encrypted. By this way, the information has been protected effectively. This paper realizes the safe communication in the MANET.
