         Identity-Based Signatures for MANET Routing Protocols
                        draft-ietf-manet-ibs-01

Abstract

   This document extends [RFC7182], which specifies a framework for, and
   specific examples of, integrity check values (ICVs) for packets and
   messages using the generalized packet/message format specified in
   [RFC5444].  It does so by defining an additional cryptographic
   function that allows the creation of an ICV that is an identity-based
   signature, defined according to the ECCSI (Elliptic Curve-Based
   Certificateless Signatures for Identity-Based Encryption) algorithm
   specified in [RFC6507].

1.  Introduction

   [RFC7182] defines ICV (integrity check value) TLVs for use in packets
   and messages that use the generalized MANET packet/message format
   defined in [RFC5444].  This specification extends the TLV definitions
   therein by defining two new cryptographic function code points that
   allow the use of an identity-based signature (IBS) as an ICV.  An IBS
   has an additional property that is not shared by any of the
   previously specified ICVs, it not only indicates that the protected
   packet or message is valid, but also verifies the originator of the
   packet/message.

   This specification assumes that each router (protocol participant)
   has an identity that may be tied to the packet or message.  The
   router may have more than one identity, but will only use one for
   each ICV TLV.  The cryptographic strength of the IBS is not dependent
   on the choice of identity.

   Two options for the choice of identity are supported (the two code
   points allocated).  In the first the identity can be any octet
   sequence (up to 255 octets) included in the ICV TLV.  In the second,
