                   Encrypted Sessions In CCNx (ESIC)

Abstract

   This document describes how to transport CCNx packets inside an
   encrypted session between peers that share a traffic secret, such as
   that which is derived from [CCNxKE].  The peers create an outer
   naming context to identify the encryption session in one direction
   between the consumer and the producer.  The consumer sends encrypted
   Interest messages to the producer, who responds with encrypted
   Content Objects.  Inside the outer context, the consumer sends
   Interests with different names, which the producer may respond to or
   may send InterestReturns for.  There does not need to be a naming
   relationship between the outer names and the inner names.  The inner
   content is still protected by normal CCNx authentication mechanisms
   and possiby encrypted under other schemes.

1.  Introduction

   CCNx packets [MESSAGES] contain a fixed header, optional hop-by-hop
   headers, a CCNx Message, and a validation section.  Encrypted
   Sessions in CCNx (ESIC) describes how to to transport encrypted CCNx
   packets inside other CCNx packets.  The outer packet (the wrapper)
