摘要
This document proposes the addition of new cipher suites to the Transport Layer Security (TLS) protocol to support the SEED encryption algorithm as a bulk cipher algorithm.
本文档建议在传输层安全（TLS）协议中添加新的密码套件，以支持作为批量密码算法的种子加密算法。
This document proposes the addition of new cipher suites to the TLS protocol [TLS] to support the SEED encryption algorithm as a bulk cipher algorithm.
本文件建议在TLS协议[TLS]中添加新的密码套件，以支持作为批量密码算法的种子加密算法。
SEED is a symmetric encryption algorithm that was developed by Korea Information Security Agency (KISA) and a group of experts, beginning in 1998. The input/output block size of SEED is 128-bit and the key length is also 128-bit. SEED has the 16-round Feistel structure. A 128-bit input is divided into two 64-bit blocks and the right 64-bit block is an input to the round function with a 64-bit subkey generated from the key scheduling.
SEED是一种对称加密算法，由韩国信息安全局（KISA）和一组专家从1998年开始开发。种子的输入/输出块大小为128位，密钥长度也为128位。种子具有16个圆形的Feistel结构。128位输入被分为两个64位块，右64位块是round函数的输入，具有从密钥调度生成的64位子密钥。
SEED is easily implemented in various software and hardware because it is designed to increase the efficiency of memory storage and the simplicity of generating keys without degrading the security of the algorithm. In particular, it can be effectively adopted in a computing environment that has a restricted resources such as mobile devices, smart cards, and so on.
SEED易于在各种软件和硬件中实现，因为它旨在提高内存存储的效率和生成密钥的简单性，而不会降低算法的安全性。特别是，它可以有效地应用于资源受限的计算环境中，如移动设备、智能卡等。
SEED is a national industrial association standard [TTASSEED] and is widely used in South Korea for electronic commerce and financial services operated on wired & wireless PKI.
SEED是一项国家工业协会标准[TTASSEED]，在韩国广泛用于基于有线和无线PKI的电子商务和金融服务。
The algorithm specification and object identifiers are described in [SEED-ALG]. The SEED homepage, http://www.kisa.or.kr/seed/seed_eng.html, contains a wealth of information about SEED, including detailed specification, evaluation report, test vectors, and so on.
算法规范和对象标识符在[SEED-ALG]中描述。种子主页，http://www.kisa.or.kr/seed/seed_eng.html，包含有关种子的丰富信息，包括详细的规格说明、评估报告、测试向量等。
The key words "MUST", "MUST NOT", "REQUIRED", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document (in uppercase, as shown) are to be interpreted as described in [RFC2119].
本文件中的关键词“必须”、“不得”、“必需”、“应该”、“不应该”、“建议”、“可以”和“可选”（大写，如图所示）应按照[RFC2119]中所述进行解释。
The new cipher suites proposed here have the following definitions:
此处提出的新密码套件具有以下定义：
CipherSuite TLS_RSA_WITH_SEED_CBC_SHA = { 0x00, 0x96};
CipherSuite TLS_DH_DSS_WITH_SEED_CBC_SHA = { 0x00, 0x97};
CipherSuite TLS_DH_RSA_WITH_SEED_CBC_SHA = { 0x00, 0x98};
CipherSuite TLS_DHE_DSS_WITH_SEED_CBC_SHA = { 0x00, 0x99};
CipherSuite TLS_DHE_RSA_WITH_SEED_CBC_SHA = { 0x00, 0x9A};
CipherSuite TLS_DH_anon_WITH_SEED_CBC_SHA = { 0x00, 0x9B};
CipherSuite TLS_RSA_WITH_SEED_CBC_SHA = { 0x00, 0x96};
CipherSuite TLS_DH_DSS_WITH_SEED_CBC_SHA = { 0x00, 0x97};
CipherSuite TLS_DH_RSA_WITH_SEED_CBC_SHA = { 0x00, 0x98};
CipherSuite TLS_DHE_DSS_WITH_SEED_CBC_SHA = { 0x00, 0x99};
CipherSuite TLS_DHE_RSA_WITH_SEED_CBC_SHA = { 0x00, 0x9A};
CipherSuite TLS_DH_anon_WITH_SEED_CBC_SHA = { 0x00, 0x9B};
All the cipher suites described here use SEED in cipher block chaining (CBC) mode as a bulk cipher algorithm. SEED is a 128-bit block cipher with 128-bit key size.
这里描述的所有密码套件都使用加密块链接（CBC）模式中的种子作为批量密码算法。SEED是一种128位的分组密码，密钥大小为128位。
All the cipher suites described here use SHA-1 [SHA-1] in an HMAC construction as described in section 5 of [TLS].
此处描述的所有密码套件在HMAC构造中使用SHA-1[SHA-1]，如[TLS]第5节所述。
The cipher suites defined here differ in the type of certificate and key exchange method. They use the following options:
此处定义的密码套件在证书类型和密钥交换方法上有所不同。他们使用以下选项：
CipherSuite Key Exchange Algorithm
密码套件密钥交换算法
TLS_RSA_WITH_SEED_CBC_SHA RSA TLS_DH_DSS_WITH_SEED_CBC_SHA DH_DSS TLS_DH_RSA_WITH_SEED_CBC_SHA DH_RSA TLS_DHE_DSS_WITH_SEED_CBC_SHA DHE_DSS TLS_DHE_RSA_WITH_SEED_CBC_SHA DHE_RSA TLS_DH_anon_WITH_SEED_CBC_SHA DH_anon

For the meanings of the terms RSA, DH_DSS, DH_RSA, DHE_DSS, DHE_RSA, and DH_anon, please refer to sections 7.4.2 and 7.4.3 of [TLS].
有关术语RSA、DH_DSS、DH_RSA、DHE_DSS、DHE_RSA和DH_anon的含义，请参考[TLS]第7.4.2节和第7.4.3节。
It is not believed that the new cipher suites are less secure than the corresponding older ones. No security problem has been found on SEED. SEED is robust against known attacks, including differential cryptanalysis, linear cryptanalysis, and related key attacks, etc. SEED has gone through wide public scrutinizing procedures. Especially, it has been evaluated and also considered cryptographically secure by trustworthy organizations such as ISO/IEC JTC 1/SC 27 and Japan CRYPTREC (Cryptography Research and Evaluation Committees) [ISOSEED] [CRYPTREC]. SEED has been submitted to several other standardization bodies such as ISO (ISO/IEC 18033-3) and IETF S/MIME Mail Security [SEED-SMIME]; and it is under consideration. For further security considerations, the reader is encouraged to read [SEED-EVAL].
人们并不认为新的密码套件不如相应的旧密码套件安全。在SEED上未发现任何安全问题。SEED对已知的攻击具有鲁棒性，包括差分密码分析、线性密码分析和相关的密钥攻击等。SEED已经通过了广泛的公开审查程序。特别是，ISO/IEC JTC 1/SC 27和日本CRYPTREC（密码学研究和评估委员会）[ISOSEED][CRYPTREC]等值得信赖的组织对其进行了评估，并认为其在加密方面是安全的。SEED已提交给其他几个标准化机构，如ISO（ISO/IEC 18033-3）和IETF S/MIME邮件安全[SEED-SMIME]；目前正在考虑。出于进一步的安全考虑，鼓励读者阅读[SEED-EVAL]。
For other security considerations, please refer to the security of the corresponding older cipher suites described in [TLS] and [AES-TLS].
有关其他安全注意事项，请参考[TLS]和[AES-TLS]中描述的相应旧密码套件的安全性。
