Session Security Envelope
draft-moskowitz-sse-05
Abstract
This memo specifies the details of the Session Security Envelope
(SSE). SSE is a session protocol aiming to guarantee
confidentiality, integrity and authentication completely
independently by the underlying context, namely network and transport
layers. A single session using the SEE protocol can include a single
transport session or multiple transport sessions. This mean that SSE
can survive the break-down in network and transport layers or to
attacks carried against them. SSE is also applicable in networks
lacking in classic inter-networking and transport protocols SSE
relies on modern AEAD block cipher modes of operations, a class of
block cipher modes which allows, at the same time, to authenticate
the message while encrypting a part of it.
Status of This Memo
This Internet-Draft is submitted in full conformance with the
provisions of BCP 78 and BCP 79.
Internet-Drafts are working documents of the Internet Engineering
