The Internet of Things (IoT) is next generation technology that is intended to improve and optimize daily life by operating intelligent sensors and smart objects together. At application layer, communication of resource constrained devices is expected to use Constrained Application Protocol (CoAP). Communication security is an important aspect of IoT environment. However closed source security solutions do not help in formulating security in IoT so that devices can communicate securely with each other. To protect the transmission of confidential information secure CoAP uses Datagram Transport Layer Security (DTLS) as the security protocol for communication and authentication of communicating devices.
