Ballot Text

This document was deferred by Terry Manderson in May 2018. The authors have taken into account all COMMENTs from the 2018 ballot, changing several parts of the document based on those COMMENTs.

The document went successfully through a new IETF last call (that Eric requested in 2020) and the authors have addressed all points raised during this Last Call (including the SECDIR review by Don Eastlake). Security AD have currently some DISCUSSs based on the May 2020 telechat (that was cancelled pending the fix to those DISCUSS). Authors have addressed in revision -21 all DISCUSS (and some COMMENTs) points raised during the 2019 IESG review.

So I am balloting the approval again in front of the 2020 IESG members.

Technical Summary

    This document specifies the Host Identity Protocol Diet EXchange
    (HIP DEX), a variant of the Host Identity Protocol Version 2
    (HIPv2).  The HIP DEX protocol design aims at reducing the
    overhead of the employed cryptographic primitives by omitting
    public-key signatures and hash functions.  In doing so, the main
    goal is to still deliver similar security properties to HIPv2.

    The HIP DEX protocol is primarily designed for computation or
    memory- constrained sensor/actuator devices.  Like HIPv2, it is
    expected to be used together with a suitable security protocol
    such as the Encapsulated Security Payload (ESP) for the protection
    of upper layer protocol data.  In addition, HIP DEX can also be
    used as a keying mechanism for security primitives at the MAC
    layer, e.g., for IEEE 802.15.4 networks.

Working Group Summary

   There was WG consensus behind this document.

Document Quality

    As discussed in RFC 6538, there are several implementations of the
    Experimental HIP specs. Nevertheless, it is not clear whether the
    HIP for Linux and OpenHIP implementations will be updated to
    comply with this specification.

    A proof-of-concept implementation of this spec for Sun SPOT
    hardware was developed in the past but is not currently being
    actively maintained. The authors also implemented this spec so
    that they could make educated design decisions about the
    protocol. However, the code was never distributed publicly. 

Personnel

   Gonzalo Camarillo is the document shepherd. Éric Vyncke is the
    responsible area director.
