A certificate based authorization and protected application layer protocol for IoT
T. Premalatha, S. Duraisamy · 2017
Safety communication is very important in emerging intelligent constrained world. In order to enhance secure communication, it is essential to enhance the unreliable Constrained Application Protocol(CoAP) by adding compressed Datagram Transport Layer Security(DTLS) Protocol based on 6LoWPAN standard. The purpose of Compressed DTLS is to minimize the length of packet and to prevent from disjunction. Along with this, the certificate based authorization encryption mechanism is added for enforcing authorized access to keep away from Denial of Service (DoS) Attacks. Finding report illustrate that CoAPs with certification afford secure message communication between the dissimilar multi vendor surroundings in intelligent world and the impact of Denial of Service Attack is reduced.
