Towards Remote Procedure Call Encryption By Default
draft-ietf-nfsv4-rpc-tls-06
Abstract
This document describes a mechanism that, through the use of
opportunistic Transport Layer Security (TLS), enables encryption of
in-transit Remote Procedure Call (RPC) transactions while
interoperating with ONC RPC implementations that do not support this
mechanism. This document updates RFC 5531.
