Abstract
The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). In accordance with an aspect of the present disclosure, a method of transmitting data in a device to device communication system is provided. The method includes determining whether a security feature is applied to one or more packet data convergence protocol (PDCP) data units, configuring the one or more PDCP data units based on the determined result, and transmitting the one or more PDCP data units to one or more receiving user equipments (UEs).

A method of transmitting data in a device to device communication system, the method comprising:
- determining whether a security feature is applied to a packet data convergence protocol (PDCP) service data unit (SDU);
- configuring a PDCP protocol data unit (PDU) based on the determination;
- and
- transmitting the PDCP PDU to a receiving user equipment (UE),
- wherein a PDCP header of the PDCP PDU includes an SDU type, a PDCP sequence number (SN), and a first key identification (ID),
- wherein, in case that the security feature is applied to the PDCP SDU, the first key ID is set to a value for identifying a first key, the first key being used to generate an encryption key for securing the PDCP SDU and being generated based on a second key identified by a second key ID, and
- wherein, in case that the security feature is not applied to the PDCP SDU, the first key ID is set to a zero value.
A method of receiving data in a device to device communication system, the method comprising:
- receiving a packet data convergence protocol (PDCP) protocol data unit (PDU);
- and
- processing the PDCP PDU configured based on whether a security feature is applied to a PDCP service data unit (SDU),
- wherein a PDCP header of the PDCP PDU includes an SDU type, a PDCP sequence number (SN), and a first key identification (ID),
- wherein, in case that the security feature is applied to the PDCP SDU, the first key ID is set to a value for identifying a first key, the first key being used to generate an encryption key for securing the PDCP SDU and being generated based on a second key identified by a second key ID, and
- wherein, in case that the security feature is not applied to the PDCP SDU, the first key ID is set to a zero value.
An apparatus for transmitting data in a device to device communication system, the apparatus comprising:
- at least one processor configured to:
- determine whether a security feature is applied to a packet data convergence protocol (PDCP) service data unit (SDU), and
- configure a PDCP protocol data unit (PDU) based on the determination;
- and
- a transmitter configured to transmit the PDCP PDU to a receiving user equipment (UE),
- wherein a PDCP header of the PDCP PDU includes an SDU type, a PDCP sequence number (SN), and a first key identification (ID),
- wherein, in case that the security feature is applied to the PDCP SDU, the first key ID is set to a value for identifying a first key, the first key being used to generate an encryption key for securing the PDCP SDU and being generated based on a second key identified by a second key ID, and
- wherein, in case that the security feature is not applied to the PDCP SDU, the first key ID is set to a zero value.
An apparatus of receiving data in a device to device communication system, the apparatus comprising:
- a receiver for receiving a packet data convergence protocol (PDCP) protocol data unit (PDU);
- and
- at least one processor configured to process the PDCP PDU configured based on whether a security feature is applied to a PDCP service data unit (SDU),
- wherein a PDCP header of the PDCP PDU includes an SDU type, a PDCP sequence number (SN), and a first key identification (ID),
- wherein, in case that the security feature is applied to the PDCP SDU, the first key ID is set to a value for identifying a first key, the first key being used to generate an encryption key for securing the PDCP SDU and being generated based on a second key identified by a second key ID, and
- wherein, in case that the security feature is not applied to the PDCP SDU, the first key ID is set to a zero value.
