SecOPP-a low-cost energy secure multi-hop routing protocol for wireless sensor networks

In this paper we are proposing an efficient secure solution to the data centric routing protocol One Phase Pull diffusion which permit multi-hop routing of sensed data. SecOPP provides both Group and Pairwise key distribution with the possibility of rekeying as well as security services: integrity, authentication and confidentiality of exchanged messages. All these are obtained without using a key distribution center or messages adjunction. Security analysis shows that SecOPP protocol can withstand several possible routing attacks in the network. Scalability and low energy consumption are well checked via implementation for TinyOS using NesC and simulated under TOSSIM.
