Routing and Data Security Scheme Based on Double Encryption in Mobile Ad Hoc Networks

Considering the results from routing attack, this paper proposes a routing and data security scheme based on double encryption in Mobile Ad Hoc Networks. After building the route, the end-to-end routing test and verification ensures the validity of the route with asymmetric encryption and data encryption ensures the safety of data on this route with symmetric encryption. Additional, the symmetric encryption key is encapsulated in routing test and verify packet and then is asymmetrically encrypted together to be sent to destination node. The simulation results show that the scheme has a better performance in complexity and system overhead. And it can protect routing and data security at the same time.
