  State-of-the-Art and Challenges for the Internet of Things Security
                    draft-irtf-t2trg-iot-seccons-04

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 for IoT are well-recognized 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.  Next, we document the
   various security threats to a thing and the challenges that one might
   face to protect against these threats.  Lastly, we discuss the next
   steps needed to ensure roll out of secure IoT services.

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