12. IANA Considerations

The RTP specification establishes a registry of profile names for use by higher-level control protocols, such as the Session Description Protocol (SDP), to refer to transport methods. This profile registers the name "RTP/SAVP".

SRTP uses cryptographic transforms which a key management protocol signals. It is the task of each particular key management protocol to register the cryptographic transforms or suites of transforms with IANA. The key management protocol conveys these protocol numbers, not SRTP, and each key management protocol chooses the numbering scheme and syntax that it requires.

Specification of a key management protocol for SRTP is out of scope here. Section 8.2, however, provides guidance on the parameters that need to be defined for the default and mandatory transforms.
