“…Hummen et al [16] deal with the constraints of IoT objects and processing the certificate-based DTLS handshakes. They propose three ideas that are based on a pre-validation, a session resumption and a handshake delegation to reduce computation and memory overheads.…”

“…Figure. Nevertheless IPv6 address space of up to 3.4×1038 will accommodate as many as 4,000 addresses for every individual of the world; the added functionalities like automatic address configuration are also going to make scalability easier. In the process of securing IoT and making it compatible with Internet, IPv6 over Low-Power Wireless Personal Area Networks (6LoWPAN) [5], Routing Over Low-power and Lossy networks (RPL) [6], Datagram Transport Layer Security (DTLS) [7], Constrained Application Protocol (CoAP ) [8] have surfaced as approved lightweight variants to IPv6, IP Routing Protocols, TLS and HTTP respectively [9]. Such variants are making constrained IoT devices capable of using IPv6 and creating a smooth communication process between IoT and Internet domains.…”

Internet of Things has become a buzzword. It refers to networking of simplest mundane objects not just for human to machine or human to human interactions but for independent thing to thing interaction as well. Such interconnected or smart environment can do wonders but at the same time poses numerous threats to human lives. The ordinary and less powerful objects from day to day life are holding sensitive and private data from humans and trying to transport that through the insecure world of Internet. This new phase of Internet or Internet of Things (IoT) is yet in its infancy and does not have a security support mechanism of its own. The Internet and World Wide Web deal with interconnection of powerful devices like computers or smart phones and are well supported by standard Internet protocols ensuring optimum security and protection. The lightweight versions of the existing Internet protocols are backing the operations of IoT to a large extent but the security needs are not met completely as of yet. Many research organizations and individual researchers are working to make existing protocols and infrastructure applicable in IoT. This paper highlights the threats posed by uncontrolled proliferation of Internet of things and discusses major protocols that have been or that are being designed to overcome the security issues raised by Internet of things Index Terms: Internet of Things (IoT), DTLS, COAP, IPSec, MQTT, SDN.

“…In this paper, we reduce the overhead of DTLS for the IoT by employing 6LoWPAN header compression mechanisms. In another work [13], we propose design ideas to reduce the energy consumption of the two-way certificate-based DTLS handshake. We suggest (i) pre-validation of certificates at the trusted 6BR, (ii) session resumption to avoid full rehandshake, and (iii) handshake delegation to the owner of the resource-constrained device.…”

The Internet of Things (IoT) enables a wide range of application scenarios with potentially critical actuating and sensing tasks, e.g., in the e-health domain. For communication at the application layer, resource-constrained devices are expected to employ the constrained application protocol (CoAP) that is currently being standardized at the Internet Engineering Task Force. To protect the transmission of sensitive information, secure CoAP mandates the use of datagram transport layer security (DTLS) as the underlying security protocol for authenticated and confidential communication. DTLS, however, was originally designed for comparably powerful devices that are interconnected via reliable, high-bandwidth links. In this paper, we present Lithe-an integration of DTLS and CoAP for the IoT. With Lithe, we additionally propose a novel DTLS header compression scheme that aims to significantly reduce the energy consumption by leveraging the 6LoWPAN standard. Most importantly, our proposed DTLS header compression scheme does not compromise the end-to-end security properties provided by DTLS. Simultaneously, it considerably reduces the number of transmitted bytes while maintaining DTLS standard compliance. We evaluate our approach based on a DTLS implementation for the Contiki operating system. Our evaluation results show significant gains in terms of packet size, energy consumption, processing time, and network-wide response times when compressed DTLS is enabled.
