name: SAID
full_form: Security Association Identifier
context: and GPI message are present. Reserved (3 bits): These bits are reserved for future versions of this specification. Implementations conforming to this specification shall set these bits to zero before transmitting a message, and the receiver of the message shall ignore these bits. GPI length (16 bits): The length of the GPI message in number of octets. This field is present only when GPI Indication is set to 1. GPI message (variable length): The GPI message. This field is present only when GPI Indication is set to 1. SN (16 bits): The sequence number used for synchronizing the encryption and providing replay-protection. Cipher suite (8 bits): The cipher suite used for protection of the message. The cipher suite consists of one integrity protection algorithm, one encryption algorithm, and one key derivation algorithm. SAID length (8 bits): The length of the SAID in number of octets. SAID (variable length): The identity of the GPL security association used for protection of the message.
description: The Security Association Identifier (SAID) is a parameter that identifies the specific security association used for protecting messages in the network. It is an essential attribute for secure communication, ensuring that the correct encryption and integrity protection algorithms are applied.
explanation: The text explicitly states that SAID is a parameter within the context of data unit transfer format, highlighting its role in defining message structure and security.
