IP Encapsulating Security Payload
RFC 4303, “IP Encapsulating Security Payload”, is a Proposed Standard document published in December 2005 by S. Kent. It obsoletes RFC 2406. The canonical text is published by the RFC Editor.
Abstract
This document describes an updated version of the Encapsulating Security Payload (ESP) protocol, which is designed to provide a mix of security services in IPv4 and IPv6. ESP is used to provide confidentiality, data origin authentication, connectionless integrity, an anti-replay service (a form of partial sequence integrity), and limited traffic flow confidentiality. This document obsoletes RFC 2406 (November 1998). [STANDARDS-TRACK]
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
