                     Camellia Cipher Suites for TLS

Abstract

   This document specifies a set of cipher suites for the Transport
   Security Layer (TLS) protocol to support the Camellia encryption
   algorithm as a block cipher.  It amends the cipher suites originally
   specified in RFC 4132 by introducing counterparts using the newer
   cryptographic hash algorithms from the SHA-2 family.  This document
   obsoletes RFC 4132.

1.  Introduction

   This document proposes the addition of new cipher suites to the
   Transport Layer Security (TLS) [RFC5246] protocol to support the
   Camellia [RFC3713] encryption algorithm as a block cipher algorithm,
   adding variants using the SHA-2 family of cryptographic hash
   algorithms [FIPS180-3] to the TLS cipher suite portfolio originally
   specified in RFC 4132 [RFC4132].  This document obsoletes RFC 4132.

   The Camellia algorithm and its properties are described in [RFC3713].

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 [RFC2119].

2.  Proposed Cipher Suites

   The cipher suites defined here have the following identifiers:

  CipherSuite TLS_RSA_WITH_CAMELLIA_128_CBC_SHA         = { 0x00,0x41 };
  CipherSuite TLS_DH_DSS_WITH_CAMELLIA_128_CBC_SHA      = { 0x00,0x42 };
  CipherSuite TLS_DH_RSA_WITH_CAMELLIA_128_CBC_SHA      = { 0x00,0x43 };
  CipherSuite TLS_DHE_DSS_WITH_CAMELLIA_128_CBC_SHA     = { 0x00,0x44 };
  CipherSuite TLS_DHE_RSA_WITH_CAMELLIA_128_CBC_SHA     = { 0x00,0x45 };
  CipherSuite TLS_DH_anon_WITH_CAMELLIA_128_CBC_SHA     = { 0x00,0x46 };

  CipherSuite TLS_RSA_WITH_CAMELLIA_256_CBC_SHA         = { 0x00,0x84 };
  CipherSuite TLS_DH_DSS_WITH_CAMELLIA_256_CBC_SHA      = { 0x00,0x85 };
  CipherSuite TLS_DH_RSA_WITH_CAMELLIA_256_CBC_SHA      = { 0x00,0x86 };
  CipherSuite TLS_DHE_DSS_WITH_CAMELLIA_256_CBC_SHA     = { 0x00,0x87 };
  CipherSuite TLS_DHE_RSA_WITH_CAMELLIA_256_CBC_SHA     = { 0x00,0x88 };
