MESSAGE AUTHENTICATION AND SECURE TRANSMISSION IN WIRELESS SENSOR NETWORKS USING GLOBAL ELLIPTIC CURVE CRYPTOGRAPHY METHOD

Abstract: Message authentication is used to stop unauthorized and corrupted messages from being in Wireless Sensor Networks (WSNs). Message authentication schemes have two approaches: public-key based and symmetric-key based approaches. To address these issues, this research work proposes a scalable authentication scheme based on Global Elliptic Curve Cryptography (GECC). The proposed scheme allows any number of messages to transmit in intermediate node authentication. In addition, the GECC scheme can also provide message source privacy and multiple base station environments. The proposed GECC scheme enables the intermediate node authentication so that all corrupted message can be detected and dropped.
