Energy Efficient PKI Secure Key Management Technique in Wireless Sensor Network Using DHA & ECC

Sensor Network are used for variety of application, such as emergency rescue, disaster relief but this is vulnerable to attacks. To make conversation confidential to the adversary so that not able to forge the data. so to provide the security for data exchange between sensors and base station energy consumption should be minimum . For secure communication in sensor network having many resource constrained, symmetric methods are preferred, because of its friendly nature of low resource consumption. But In this paper we propose an energy efficient secure pubic key algorithm that proves the authentication and also provides secure communication among sensor in such a way that energy consumption minimizes.
