              Remote Procedure Call Encryption By Default
                       draft-cel-nfsv4-rpc-tls-02

Abstract

   This document describes a mechanism that enables encryption of in-
   transit Remote Procedure Call (RPC) transactions with minimal
   administrative overhead and full interoperation with RPC
   implementations that do not support this mechanism.  This document
   updates RFC 5531.

1.  Introduction

   In 2014 the IETF published [RFC7258] which recognized that
   unauthorized observation of network traffic had become widespread and
   was a subversive threat to all who make use of the Internet at large.
   It strongly recommended that newly defined Internet protocols make a
   real effort to mitigate monitoring attacks.  Typically this
   mitigation is done by encrypting data in transit.

   The Remote Procedure Call version 2 protocol has been a Proposed
   Standard for three decades (see [RFC5531] and its antecedants).
