Advanced Secure Architecture for the Internet of Things based on DTLS Protocol

Abstract: This study presents an authentication security scheme for implementation on the Internet of Things (IoT). This scheme is reliant on the prevailing Internet standards, particularly on the Datagram Transport Layer Security (DTLS) protocol. The reliance of this scheme on an existing standard facilitates the reuse of the existing engineering techniques, implementations, and security features in the new scheme, thereby enabling easy security uptake. The scheme proposed in this study is based on RSA, which is the commonly used public-key cryptographic framework. Its design supports execution over the standard communication stacks that offer UDP/IPv6 networking for 6LoWPANs. In this study, DTLS was implemented from the perspective of a systems framework. The feasibility of the scheme in terms of high interoperability and low overheads is also proven via several evaluations on a suitable hardware platform for IoT.
