2016. Lightweight Authentication for COAP Based IOT. Proceedings of the 6th International Conference on the Internet of Things. :167–168.
Security of Constrained application protocol(COAP) used instead of HTTP in Internet of Thing s(IoT) is achieved using DTLS which uses the Internet key exchange protocol for key exchange and management. In this work a novel key exchange and authentication protocol is proposed. CLIKEv2 protcol is a certificate less and light weight version of the existing protocol. The protocol design is tested with the formal protcol verification tool Scyther, where no named attacks are identified for the propsed protocol. Compared to the existing IKE protocol the CLIKEv2 protocol reduces the computation time, key sizes and ultimately reduces energy consumption.
