Secure-EEDR: Dynamic Key Exchange Protocol Based on Diffie-Hellman Algorithm with NOVSF Code-Hopping Technique for Wireless Sensor Networks

Secure data transmission and data routing are critical in designing cluster based sensor network. This paper presents a secure energy efficient dynamic routing scheme (SEEDR) for wireless sensor networks. SEEDR uses a symmetric cryptography algorithm to support security. The dynamic key exchange protocol based on DH (Diffie-Hellman) algorithm is proposed, with non blocking OVSF codes. Our analytical model and the security analysis prove that SEEDR increase data communication security and consume less communication energy.
