               Enrollment with Application Layer Security
                       draft-selander-ace-eals-01

Abstract

   This document specifies public key certificate enrollment procedures
   authenticated with application-layer security protocols suitable for
   Internet of Things deployments.  The protocols leverage existing IoT
   standards including Constrained Application Protocol (CoAP), Concise
   Binary Object Representation (CBOR) and the CBOR Object Signing and
   Encryption (COSE) format.

1.  Introduction

   Asymmetric cryptography with Public Key Infrastructure (PKI) is a de-
   facto key exchange and mutual authentication solution in the
   Internet.  Though solutions based on PSK are still state-of-the-art
   in sensor networks they are not scalable to Internet-connected
   billions of things.  Therefore, most IoT security standards support
   asymmetric cryptographic protocols.  The greatest challenge with
