       State of the Art and Challenges for the Internet of Things
                      draft-irtf-t2trg-iot-seccons-02

Abstract

   The Internet of Things concept refers to the usage of standard
   Internet protocols to allow for human-to-thing or thing-to-thing
   communication.  The security needs are well-recognized and and many
   standardization steps have been taken, for example, specification of
   CoAP over DTLS.  However, security challenges still exist and there
   are some use cases that lack a suitable solution.  This document
   first provides an overview of security architecture, its deployment
   model, security needs in the context of the lifecycle of a thing, as
   well as the state of the art on IoT security.  Then, we discuss the
   concept of security profiles for the successful roll-out of secure
   IoT applications and describe remaining security challenges in the
   IoT.
