This document updates IANA registries to support the SEED [RFC4269] block cipher algorithm for the Secure Real-time Transport Protocol (SRTP) and the Secure Real-time Transport Control Protocol (SRTCP) [RFC3711] in Multimedia Internet KEYing (MIKEY) [RFC3830].
本文档更新IANA注册表，以支持多媒体互联网密钥（MIKEY）[RFC3830]中安全实时传输协议（SRTP）和安全实时传输控制协议（SRTCP）[RFC3711]的SEED[RFC4269]分组密码算法。
SEED is a 128-bit symmetric key block cipher that has been developed by KISA (Korea Information Security Agency) and a group of experts since 1998. The input/output block size of SEED is 128-bit, and the key length is also 128-bit. SEED has a 16-round Feistel structure.
SEED是一种128位对称密钥分组密码，由KISA（韩国信息安全局）和一组专家自1998年以来开发。种子的输入/输出块大小为128位，密钥长度也为128位。种子有16个圆形的Feistel结构。
SEED is a Korean National Industrial Association standard and is widely used in South Korea for electronic commerce and various security products such as firewalls, VPNs, and so on.
SEED是韩国国家工业协会标准，在韩国广泛用于电子商务和各种安全产品，如防火墙、VPN等。
This section specifies new code points for the MIKEY [RFC3830] payload to indicate the use of the SEED cipher algorithm for SRTP and SRTCP. There are three applicable modes of running SEED: SEED in Counter Mode (SEED-CTR), SEED in Counter with CBC-MAC Mode (SEED-CCM), and SEED in Galois/Counter Mode (SEED-GCM) Mode. These are defined in [RFC5669].
本节指定MIKEY[RFC3830]有效负载的新代码点，以指示对SRTP和SRTCP使用种子密码算法。运行SEED有三种适用模式：计数器模式下的SEED（SEED-CTR）、CBC-MAC模式下的计数器中的SEED（SEED-CCM）和Galois/计数器模式下的SEED（SEED-GCM）。这些在[RFC5669]中定义。
IANA has amended the sub-registry derived from Table 6.10.1.b of [RFC3830] as follows:
IANA已将源自[RFC3830]表6.10.1.b的子注册表修改如下：
SRTP encr alg | Value

AES-CM | 1
AES-F8 | 2
SEED-CTR | 3 (NEW)
SEED-CCM | 4 (NEW)
SEED-GCM | 5 (NEW)
SRTP encr alg | Value
---------------------
NULL | 0
AES-CM | 1
AES-F8 | 2
SEED-CTR | 3 (NEW)
SEED-CCM | 4 (NEW)
SEED-GCM | 5 (NEW)

IANA has amended the sub-registry derived from Table 6.10.1.d of [RFC3830] as follows:
IANA已将源自[RFC3830]表6.10.1.d的子注册表修改如下：
SRTP PRF | Value

No security problem has been found on SEED. SEED is secure against all known attacks including differential cryptanalysis, linear cryptanalysis, and related key attacks. The only known attack is an exhaustive search for the key. For further security considerations, the reader is encouraged to read [SEED-EVAL].
在SEED上未发现任何安全问题。SEED对所有已知的攻击都是安全的，包括差分密码分析、线性密码分析和相关的密钥攻击。唯一已知的攻击是彻底搜索密钥。出于进一步的安全考虑，鼓励读者阅读[SEED-EVAL]。
IANA has amended the indicated sub-registries in Section 2 of the MIKEY [RFC3830] Payload Name registry according to Sections 2.1 and 2.2 above.
IANA已根据上述第2.1节和第2.2节修改了MIKEY[RFC3830]有效负载名称注册表第2节中指定的子注册表。
