Data Security Transmission Based on DHT route Protocol

The route protocol based on distributed hash table (DHT), in cableless adhoc system (CASYS), has realizes the scalability of route discovery by avoiding flooding mechanism. The safety of route protocol on the basis of DHT is count much, and solving the security problem of route protocol based on DHT can avoid business interruption, reduce excessive consumption of flow and decrease loss of data in the meshwork. Aiming at a few common safety problems, the present text put forward a new route protocol based on DHT, which uses figure sign and Customer’s belief to realize the secure exchange of logical identifier. Belief between nodes is based on familiar customers and first-sight feelings. Experimental data show that the protocol is effective in standardization overhead, improvement percentage and packet delivery rate.
