Abstract
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. It is possible to provide methods for enhancing security when a UE and a base station perform data communication in a next-generation mobile communication system according to an embodiment of the disclosure.
Claims16
A method performed by a transmitting apparatus in a wireless communication system, the method comprising:
- generating at least one medium access control (MAC) sub protocol data unit (subPDU);
- generating a first field, by applying an integrity protection procedure configured in a MAC layer of the transmitting apparatus, to the at least one MAC subPDU;
- generating a MAC PDU including the at least one MAC subPDU and the first field;
- and
- transmitting, to a receiving apparatus, the MAC PDU,
- wherein the MAC PDU further includes an indicator indicating that the at least one MAC subPDU is integrity protected.
A method performed by a receiving apparatus in a wireless communication system, the method comprising:
- receiving, from a transmitting apparatus, a medium access control (MAC) protocol data unit (PDU) including at least one MAC subPDU and a first field;
- identifying the first field;
- and
- verifying, by a MAC layer of the receiving apparatus, an integrity protection of the at least one MAC subPDU based on the first field,
- wherein the MAC PDU further includes an indicator indicating that the at least one MAC subPDU is integrity protected.
A transmitting apparatus in a wireless communication system, the transmitting apparatus comprising:
- a transceiver;
- and
- a controller coupled with the transceiver and configured to:
- generate at least one medium access control (MAC) sub protocol data unit (subPDU),
- generate a first field, by applying an integrity protection procedure configured in a MAC layer of the transmitting apparatus, to the at least one MAC subPDU,
- generate a MAC PDU including the at least one MAC subPDU and the first field, and
- transmit, to a receiving apparatus, the MAC PDU,
- wherein the MAC PDU further includes an indicator indicating that the at least one MAC subPDU is integrity protected.
A receiving apparatus in a wireless communication system, the receiving apparatus comprising:
- a transceiver;
- and
- a controller coupled with the transceiver and configured to:
- receive, from a transmitting apparatus, a medium access control (MAC) protocol data unit (PDU) including at least one MAC subPDU and a first field,
- identify the first field, and
- verifying, by a MAC layer of the receiving apparatus, an integrity protection of the at least one MAC subPDU based on the first field,
- wherein the MAC PDU further includes an indicator indicating that the at least one MAC subPDU is integrity protected.
