Key Management and Authentication in Ad Hoc Network based on Mobile Agent

摘要: Key management and authentication is important to security of Mobile Ad Hoc network (MANET). Based on the (t, n) threshold cryptography, this paper introduced mobile agents exchange private key topological information with nodes in network. This method avoids a centralized certification authority distribute public keys certificates, thus enhances security. Carrying some state variables, navigate according visitsbalance policy, namely, node least visits would be first visited by agent. Any t can cooperate perform an upon new wanting join Experimental results show that agent performs very well for improving success ratio enhance while reducing communication overhead resource consumption.
