Abstract
This document describes the use of the Camellia block cipher
algorithm in Cipher Block Chaining (CBC) mode, Counter (CTR) mode,
and Counter with CBC-MAC (CCM) mode as additional, optional-to-
implement Internet Key Exchange Protocol version 2 (IKEv2) and
Encapsulating Security Payload (ESP) mechanisms to provide
confidentiality, data origin authentication, and connectionless
integrity.

1. Introduction
This document describes the use of the Camellia block cipher
algorithm [1] in Cipher Block Chaining (CBC) mode, Counter (CTR)
mode, and Counter with CBC-MAC (CCM) mode as additional, optional-to-
implement IKEv2 [2] and Encapsulating Security Payload (ESP) [3]
mechanisms to provide confidentiality, data origin authentication,
and connectionless integrity.
Since optimized source code is provided under several open source
licenses [9], Camellia is also adopted by several open source
projects (OpenSSL, FreeBSD, Linux, and Firefox Gran Paradiso).
The algorithm specification and object identifiers are described in
[1].
The Camellia web site [10] contains a wealth of information about
Camellia, including detailed specification, security analysis,
performance figures, reference implementation, optimized
implementation, test vectors, and intellectual property information.
The remainder of this document specifies the use of various modes of
operation for Camellia within the context of IPsec ESP. For further
information on how the various pieces of IPsec in general and ESP in
particular fit together to provide security services, please refer to
[11] and [3].

1.1. Terminology
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in [4].
