Camellia Cipher Suites for TLS
茶花密码套件
Abstract
摘要
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.
本文档为传输安全层（TLS）协议指定了一组密码套件，以支持作为分组密码的Camellia加密算法。它通过引入使用SHA-2家族中较新的加密散列算法的副本，修改了RFC 4132中最初指定的密码套件。本文件淘汰了RFC 4132。

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.
本文件建议在传输层安全（TLS）[RFC5246]协议中添加新的密码套件，以支持作为分组密码算法的Camellia[RFC3713]加密算法，并使用SHA-2系列加密哈希算法[FIPS180-3]将变体添加到最初在RFC 4132中指定的TLS密码套件组合中[RFC4132]。本文件淘汰了RFC 4132。

The CAMELLIA_128_CBC cipher suites use Camellia [RFC3713] in Cipher Block Chaining (CBC) mode with a 128-bit key and 128-bit IV; the CAMELLIA_256_CBC cipher suites use a 256-bit key and 128-bit IV.

The cipher suites ending with _SHA use HMAC-SHA1 as the MAC algorithm.
以_SHA结尾的密码套件使用HMAC-SHA1作为MAC算法。
When used with TLS versions prior to 1.2, the pseudorandom function (PRF) is calculated as specified in the appropriate version of the TLS specification.
当与1.2之前的TLS版本一起使用时，伪随机函数（PRF）按照TLS规范相应版本中的规定计算。
The cipher suites ending with _SHA256 use HMAC-SHA-256 as the MAC algorithm. The PRF is the TLS PRF [RFC5246] with SHA-256 as the hash function. These cipher suites MUST NOT be negotiated by TLS 1.1 or earlier versions. Clients MUST NOT offer these cipher suites if they do not offer TLS 1.2 or later. Servers that select an earlier version of TLS MUST NOT select one of these cipher suites.
以_SHA256结尾的密码套件使用HMAC-SHA-256作为MAC算法。PRF是TLS PRF[RFC5246]，SHA-256作为哈希函数。TLS 1.1或更早版本不得协商这些密码套件。如果客户不提供TLS 1.2或更高版本，则不得提供这些密码套件。选择TLS早期版本的服务器不得选择这些密码套件之一。
