Compact Object Security for the Internet of Things

Abstract: The Internet of Things is coming. With it comes security challenges not present on common, more capable, devices such as desktop computers or servers. We argue that traditional channel security needs to be complemented with object security to cope with the constrained nature of small devices and Low Power Lossy Networks. The main reason for a partial transition to object security being heavy use of asynchronous communication. This thesis explores the feasibility of OSCoAP, a novel draft for an object security solution for CoAP, on constrained devices. It also evaluates the performance of OSCoAP compared to the well known channel security standard DTLS.
