Abstract
The present disclosure relates to the field of communications, and provides a sidelink communication method and device. The method comprises: receiving a direct communication request, wherein the direct communication request comprises a Layer 2 identifier and encrypted information for sidelink communication; according to the Layer 2 identifier, determining a security key used for decrypting the encrypted information; and using the security key to decrypt the encrypted information to facilitate sidelink communication. Therefore, secure sidelink communication can be achieved.
Claims21
A method for sidelink (SL) communication, performed by a user equipment (UE), comprising:
- receiving a direct communication request (DCR), wherein the DCR comprises a destination layer 2 identification (ID) and encrypted information for the SL communication;
- determining a security key for decrypting the encrypted information based on the destination layer 2 ID;
- and
- decrypting the encrypted information using the security key for performing the SL communication.
8-14. (canceled)
A communication device, comprising:
- a transceiver;
- a memory;
- and
- a processor connected to both the transceiver and the memory, wherein the processor is configured to:
- receive a direct communication request (DCR), wherein the DCR comprises a destination layer 2 identification (ID) and encrypted information for sidelink (SL) communication;
- determine a security key for decrypting the encrypted information based on the destination layer 2 ID;
- and
- decrypt the encrypted information using the security key for performing the SL communication.
A non-transitory computer storage medium storing computer-executable instructions thereon, wherein when the computer-executable instructions are executed by a processor of a user equipment (UE), the UE is caused to perform a method for sidelink (SL) communication, the method comprising:
- receiving a direct communication request (DCR), wherein the DCR comprises a destination layer 2 identification (ID) and encrypted information for the SL communication;
- determining a security key for decrypting the encrypted information based on the destination layer 2 ID;
- and
- decrypting the encrypted information using the security key for performing the SL communication.
