SECURE COMMUNICATION FOR LAN AND WAN IN WIRELESS SENSOR NETWORKS INTO INTERNET OF THINGS

Abstract – A secure channel between a sensor node and internet host is created, hence new security challenges arises and wireless sensor networks is integrated into internet of things. We use heterogeneous online/offline signcryption scheme so that secure communication is provided. We use bilinear diffie- hellman inversion problem in random oracle model, it provides indistinguishability against adaptive chosen ciphertext attacks and existential unforgeability against adaptive chosen messages attacks. This scheme has the following advantages: First, it achieves confidentiality, integrity, authentication, and non- repudiation in a logical single step. Second, it allows a sensor node in an identity-based cryptography to send a message to an Internet host in a public key infrastructure. Third, it splits the signcryption into two phases: i) offline phase; and ii) online phase. In offline phase heavy computations are carried out and in online phase light computations are done. This scheme is suitable to provide security solution for integrating WSN into the IoT. We use this scheme and perform an industrial application
