pySRUP - Simplifying Secure Communications for Command & Control in the Internet of Things

Andrew John Poulter, Steven J. Johnston, Simon J. Cox

Abstract: Devices connected as a part of the Internet of Things, and other connected devices, require secure mechanisms to facilitate the propagation of Command & Control messages to enable the remote management of the devices. The Secure Remote Update Protocol (SRUP) provides a mechanism to facilitate the formation of secure messages for transmission using common techniques. This paper describes the details of, and motivations behind, the creation of a Python wrapper for SRUP: and describes a worked example of usage. By using pySRUP a developer can integrate SRUP into their projects: with minimal additional effort, and requiring them to write less code than traditional unsecured alternatives.
