Secured Light Weight Methodology for Wireless Sensor Network

Abstract

Restriction-specific wireless sensor networks need secure and efficient communication mechanisms. In this document, we propose a Light Security methodology that meets both requirements. It provides authentication and authorization of sensor nodes with a simple scheme of secure exchange of keys. It also provides data confidentiality and protection mechanism against intrusions and anomalies. To address security vulnerabilities in a wireless sensor network, this document proposes a safe lightweight methodology that takes into account the limitations of sensor networks. With the help of a base station, a hierarchical network topology is formed that allows end-to-end communication between the sensor nodes. It also supports the identification and isolation of aberrant sensor nodes
