For solving the security issues of directed diffusion in wireless sensor networks
a secure directed diffusion protocol based on random key predistribution model was proposed
which extends the security of directed diffusion protocol and provides node-to-node secure data communication by setting up secure gradients and applying cumulative message authentication code and multilayer encryption. Security analyses show that the proposed protocol can ensure the security in interest propagation
data propagation
routing setting and path reinforcement phases of directed diffusion
and defend against attacks launched by compromised nodes efficiently.
