       Requirements to Secure End to End Privacy in IdLoc Systems
                      draft-xyz-pidloc-reqs-00.txt

Abstract

   Use of Identifier Locator separation systems is proposed for various
   use cases to allow for efficient and service aware flexible end-to-
   end routing.  A statement on the issue of privacy preservation of
   both users and devices identity and location describes major
   challenges identified for this problem.  This document attempts to
   derive requirements towards a potential solution space of approaches
   to preserve privacy in Identifier-Locator split (PidLoc) protocols.

1.  Introduction

   [I-D.xyz-pidloc-ps] has identified and described typical use cases
   for application of privacy preserving Identifier-Locator split
   (PidLoc) approaches and derived thereof a problem statement
   describing corresponding issues and challenges.  Privacy in this
   respect includes prevention of acquisition of personal information,
   behavioral details, and location information by unauthorised parties.
   This document tries to assess that set of issues and challenges to
   come up with a set of requirements for approaches towards service
   specific and optimized packet routing based on Id-Loc principle
   providing privacy and security.
