name: MSB
full_form: Most significant bit
context: to the initiating UE by sending a DSM Command message which includes the LSB of Kd session ID and the V2X service. The MSB of Kd session ID received on the DCR message may be specified as well. 3. The initiating UE receiving a DSM Command message from the peer UE1 forms the session identifier by concatenating the MSB and LSB of the Kd session ID (i.e. MSB of Kd session ID + LSB of Kd session ID #1). The initiating UE verifies that this session identifier is unique and creates a security context to be associated with this session identifier. The received LSB of Kd session ID and its previously generated MSB of Kd session ID are saved in this context. The initiating UE replies with a DSM Complete message and may specify the received LSB of Kd session ID. 3a.The initiating UE also receives a DSM Command message from the peer UE3. The initiating UE forms a second session identifier by concatenating the MSB of Kd session ID with the LSB of Kd session ID #3, verifies its uniqueness and
description: The Most Significant Bit (MSB) is a critical attribute in forming the session identifier for secure communication between UEs. It is used in conjunction with the Least Significant Bit (LSB) to create a unique session ID, which is then verified and associated with a security context.
explanation: The MSB is classified as a Parameter because it refers to a specific bit of data (the most significant bit of the Kd session ID) that plays a crucial role in establishing secure sessions between UEs. The context highlights its importance in forming unique session identifiers and associating them with security contexts.
