Abstract

   This document describes the use of the Camellia block cipher
   algorithm in Cipher Block Chaining Mode, with an explicit
   Initialization Vector, as a confidentiality mechanism within the
   context of the IPsec Encapsulating Security Payload (ESP).

1.  Introduction

   This document describes the use of the Camellia block cipher
   algorithm in Cipher Block Chaining Mode, with an explicit
   Initialization Vector, as a confidentiality mechanism within the
   context of the IPsec Encapsulating Security Payload (ESP).

   Camellia was selected as a recommended cryptographic primitive by the
   EU NESSIE (New European Schemes for Signatures, Integrity and
   Encryption) project [NESSIE] and was included in the list of
   cryptographic techniques for Japanese e-Government systems that was
   selected by the Japan CRYPTREC (Cryptography Research, Evaluation
   Committees) [CRYPTREC].  Camellia has been submitted to several other
   standardization bodies, such as ISO (ISO/IEC 18033) and the IETF
   S/MIME Mail Security Working Group [Camellia-CMS].

RFC 4312                    Camellia Cipher                December 2005


   Camellia supports 128-bit block size and 128-, 192-, and 256-bit key
   lengths, i.e., the same interface specifications as the Advanced
   Encryption Standard (AES) [AES].

   Camellia is a symmetric cipher with a Feistel structure.  Camillia
   was developed jointly by NTT and Mitsubishi Electric Corporation in
   2000.  It was des...
