Secure message transmission scheme in wireless sensor networks

Wireless sensor networks (WSNs) have been the subject of intensive research in past few years and backbone most maximum present information technology. WSNs employed various applications such as track monitoring battlegrounds military fields patients’ medical requirements civilian field. The wireless are always randomly distributed an open area (hostile), pervasive environment, media channel. Thus, vulnerable to several species attacks. Moreover, messages may be easily intercepted or altered because transmission is not secure, hence effective key management scheme strongly needed reduce risks. Cryptography methods a crucial aspect reach security goals. In this paper, we propose efficient secure message that combines Knapsack algorithm with Diffie-Hellmann process encrypt messages. results analysis show proposed it achieves goals providing high privacy security. It also resilient against some well-known
