Abstract: The Internet of Things (IoT) is a rapidly growing network of connected devices that are changing the way we live and work. Security is a critical issue for IoT deployments, as these devices are often vulnerable to attack. This paper provides an overview of the efforts in the Internet Engineering Task Force (IETF) to standardize security solutions for the IoT ecosystem. The paper first reviews the standard security protocols that can be used to secure IoT communications, with a focus on the Constrained Application Protocol (CoAP) and Datagram Transport Layer Security (DTLS). The paper then discusses the latest standardization efforts to adapt and enhance DTLS for IoT applications. This includes the use of raw public keys, extending DTLS record Layer to protect group communication, and profiling DTLS for embedded devices. The paper also reviews compression schemes that are being proposed in the IETF to mitigate message fragmentation issues in DTLS. The paper concludes by discussing the challenges and opportunities for securing IoT communications.

Keywords: Communication security, compression scheme, end-to-end security, Internet of Things (IoT), machine-to machine communication, standardization.
