       State of the Art and Challenges for the Internet of Things

Abstract

   The Internet of Things (IoT) concept refers to the usage of standard
   Internet protocols to allow for human-to-thing and thing-to-thing
   communication.  The security needs are well-recognized and and many
   standardization steps for providing security have been taken, for
   example, the specification of Constrained Application Protocol (CoAP)
   over Datagram Transport Layer Security (DTLS).  However, security
   challenges still exist and there are some use cases that lack a
   suitable solution.  In this document, we first discuss the various
   stages in the lifecycle of a thing.  We then look at the security
   building blocks available for securing the different layers of the
   Internet protocol suite.  Next, we document the various security
   threats to a thing and the challenges that one might face in order to
   protect against these threats.  Lastly, we discuss the next steps
   needed to ensure roll out of secure Internet of Things services.

   This document is a product of the IRTF Thing-to-Thing Research Group
   (T2TRG).
