Lightweight DTLS implementation in CoAP-based Internet of Things
Vishwas Lakkundi, Keval Singh · 2014
Security is emerging as a key area of focus in the Internet of Things. Lightweight implementations of the required security features are the need of the hour considering the resource constrained nature of the underlying nodes and networks. At the same time, it is essential to ensure that such implementations are robust, reliable and efficient. This paper addresses this need by providing a framework for implementing a lightweight version of the Datagram Transport Layer Security protocol in the Internet of Things. In addition, a real-world application scenario incorporating this lightweight security approach is included for illustration in this position paper. It also sheds light on the ongoing standardization activities in the security domain and relevant future directions to help practitioners keep abreast of all the related developments.
