In this paper we present a lightweight security scheme for authentication and key management to establish a secure channel for Intelligent Transportation System (ITS) for an IoT (Internet of Things) application. We choose Constrained Application Protocol (CoAP) as lightweight application layer protocol. Low overhead security is still an open challenge for CoAP. We propose a payload embedded low cost symmetric-key based robust authentication and key management mechanism on CoAP. This minimizes the security overhead by eliminating expensive handshaking and ciphersuite agreement of standard TLS and DTLS. We propose some unique modification in the CoAP header to invoke its secure mode in an optimized manner. Further, we propose a secure channel with adaptive reliability which reduces the overall communication cost. Such a low overhead security scheme for CoAP is hitherto unexplored. The efficacy of our proposed scheme is demonstrated through laboratory experiments in an emulated environment.
