       Security Considerations in the IP-based Internet of Things
                      draft-irtf-t2trg-iot-seccons-01

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.  Although the security needs are well-recognized, it
   is still not fully clear how existing IP-based security protocols
   should be applied to this new setting.  This Internet-Draft first
   provides an overview of security architecture, its deployment model
   and general security needs in the context of the lifecycle of a
   thing.  Then, it presents challenges and requirements for the
   successful roll-out of new applications and usage of standard IP-
   based security protocols when applied to get a functional Internet of
   Things.

Status of This Memo

   This Internet-Draft is submitted in full conformance with the
   provisions of BCP 78 and BCP 79.

   Internet-Drafts are working documents of the Internet Engineering
   Task Force (IETF).  Note that other groups may also distribute
   working documents as Internet-Drafts.  The list of current Internet-
   Drafts is at http://datatracker.ietf.org/drafts/current/.
