Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A user equipment (UE) receives master security key update information in the RRC (Radio Resource Control) reconfiguration message. UE receives a cell switch command for a master cell group (MCG) and performs the cell switch from a serving cell to a target cell. For the target cell, UE performs a security key update based on the master security key update information. UE receives a master security key update identifier for each candidate cell and maintains a variable to store a master security key update identifier for the serving cell. If the master security key update identifier of the target cell is different from that of the serving cell, UE performs a security key update for the cell switch.
