context: allowed. The following applies only for streaming services: - Only one CryptoSession can be transported in the field CS ID map info for streaming. - The #CS field shall be set to one, and CS ID map info shall be present in the MSK message. - The CS ID map type subfield shall be set to âSRTP-IDâ as defined in RFC 4563 [16]. - The SP payload shall be used only with streaming services. - Security Policy (SP) payload shall include information for the security protocol such as algorithms to use, key lengths, initial values for algorithms etc. - The BM-SC shall ensure that the UE has received the SP payload before the SP payload needs to be applied in the streaming service. - The BM-SC is not allowed to change the SP payload anymore once the streaming service using that SP has started for the first time. - The BM-SC shall include the SP payload when the MSK delivery was triggered by the UE using the MSK request procedure or the MBMS User Service Registration procedure, otherwise it is
description: A component of the MSK message that contains information for the security protocol used in streaming services. It includes details such as algorithms to use, key lengths, and initial values for algorithms.
explanation: The text describes the Security Policy (SP) payload as part of an MSK message specifically designed to carry security-related information for streaming services. This clearly defines it as a type of security policy.
