Abstract This document specifies a set of elliptic curve cipher suites for the Kanno & Kanda Expires October 7, 2009 [Page 1] Internet-Draft Addition of Camellia ECC Cipher Suites April 2009 Transport Security Layer (TLS) protocol to support the Camellia encryption algorithm as a block cipher. This document describes sixteen new cipher suites for TLS that specify HMAC-SHA1 and HMAC- SHA2. 1. Introduction This document specifies a set of elliptic curve cipher suites for the Transport Security Layer (TLS) protocol to support the Camellia encryption algorithm as a block cipher. This document describes sixteen new cipher suites for TLS that specify HMAC-SHA1 and HMAC- SHA2. The algorithm specification and object identifiers 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. Cipher Suites This document defines sixteen new cipher suites to be added to TLS. All use Elliptic Curve Cryptography for key exchange and digital signature, as defined in [RFC4492]. The sixteen cipher suites use Camellia [RFC3713] in Cipher Block Chaining (CBC) mode with HMAC-based MAC. The cipher suites defined here have the following identifiers: Kanno & Kanda Expires October 7, 2009 [Page 2] Internet-Draft Addition of Camellia ECC Cipher Suites April 2009 CipherSuite TLS_ECDH_ECDSA_WITH_CAMELLIA_128_CBC_SHA = {TBD,TBD} CipherSuite TLS_ECDH_ECDSA_WITH_CAMELLIA_256_CBC_SHA = {TBD,TBD} CipherSuite TLS_ECDHE_ECDSA_WITH_CAMELLIA_128_CBC_SHA = {TBD,TBD} CipherSuite TLS_ECDHE_ECDSA_WITH_CAMELLIA_256_CBC_SHA = {TBD,TBD} CipherSuite TLS_ECDH_RSA_WITH_CAMELLIA_128_CBC_SHA = {TBD,TBD} CipherSuite TLS_ECDH_RSA_WITH_CAMELLIA_256_CBC_SHA = {TBD,TBD} CipherSuite TLS_ECDHE_RSA_WITH_CAMELLIA_128_CBC_SHA = {TBD,TBD} CipherSuite TLS_ECDHE_RSA_WITH_CAMELLIA_256_CBC_SHA = {TBD,TBD} CipherSuite TLS_ECDHE_ECDSA_WITH_CAMELLIA_128_CBC_SHA256 = {TBD,TBD}; CipherSuite TLS_ECDHE_ECDSA_WITH_CAMELLIA_256_CBC_SHA384 = {TBD,TBD}; CipherSuite TLS_ECDH_ECDSA_WITH_CAMELLIA_128_CBC_SHA256 = {TBD,TBD}; CipherSuite TLS_ECDH_ECDSA_WITH_CAMELLIA_256_CBC_SHA384 = {TBD,TBD}; CipherSuite TLS_ECDHE_RSA_WITH_CAMELLIA_128_CBC_SHA256 = {TBD,TBD}; CipherSuite TLS_ECDHE_RSA_WITH_CAMELLIA_256_CBC_SHA384 = {TBD,TBD}; CipherSuite TLS_ECDH_RSA_WITH_CAMELLIA_128_CBC_SHA256 = {TBD,TBD}; CipherSuite TLS_ECDH_RSA_WITH_CAMELLIA_256_CBC_SHA384 = {TBD,TBD}; 3. IANA Considerations IANA is requested to allocate the following numbers in the TLS Cipher Suite Registry: CipherSuite TLS_ECDH_ECDSA_WITH_CAMELLIA_128_CBC_SHA = {TBD,TBD} CipherSuite TLS_ECDH_ECDSA_WITH_CAMELLIA_256_CBC_SHA = {TBD,TBD} CipherSuite TLS_ECDHE_ECDSA_WITH_CAMELLIA_128_CBC_SHA = {TBD,TBD} CipherSuite TLS_ECDHE_ECDSA_WITH_CAMELLIA_256_CBC_SHA = {TBD,TBD} CipherSuite TLS_ECDH_RSA_WITH_CAMELLIA_128_CBC_SHA = {TBD,TBD} CipherSuite TLS_ECDH_RSA_WITH_CAMELLIA_256_CBC_SHA = {TBD,TBD} CipherSuite TLS_ECDHE_RSA_WITH_CAMELLIA_128_CBC_SHA = {TBD,TBD} CipherSuite TLS_ECDHE_RSA_WITH_CAMELLIA_256_CBC_SHA = {TBD,TBD} CipherSuite TLS_ECDHE_ECDSA_WITH_CAMELLIA_128_CBC_SHA256 = {TBD,TBD}; CipherSuite TLS_ECDHE_ECDSA_WITH_CAMELLIA_256_CBC_SHA384 = {TBD,TBD}; CipherSuite TLS_ECDH_ECDSA_WITH_CAMELLIA_128_CBC_SHA256 = {TBD,TBD}; CipherSuite TLS_ECDH_ECDSA_WITH_CAMELLIA_256_CBC_SHA384 = {TBD,TBD}; CipherSuite TLS_ECDHE_RSA_WITH_CAMELLIA_128_CBC_SHA256 = {TBD,TBD}; CipherSuite TLS_ECDHE_RSA_WITH_CAMELLIA_256_CBC_SHA384 = {TBD,TBD}; CipherSuite TLS_ECDH_RSA_WITH_CAMELLIA_128_CBC_SHA256 = {TBD,TBD}; CipherSuite TLS_ECDH_RSA_WITH_CAMELLIA_256_CBC_SHA384 = {TBD,TBD}; 4. Security Considerations At the time of writing this document, there are no known weak keys for Camellia. Kanno & Kanda Expires October 7, 2009 [Page 3] Internet-Draft Addition of Camellia ECC Cipher Suites April 2009 The security considerations in RFC 5289 [RFC5289] apply to this document as well. 5.
