Abstract
The disclosure discloses a security configuration method for Device to Device (D2D) communication, a Proximity-based Service (ProSe) key management function, User Equipment (UE) and a system. The method includes that: first information indicating security capability of a UE is acquired; and whether to feed back a security configuration response message or a content of the security configuration response message to the UE is determined according to the first information. The disclosure further discloses a computer storage medium.
Claims13
A security configuration method for Device to Device (D2D) communication, comprising:
- receiving, by a Proximity-based Service (ProSe) key management function device, first information indicating security capability of a User Equipment (UE) from the UE;
- wherein the first information comprises a security algorithm set supported by the UE;
- and
- judging, by the ProSe key management function device, whether the security algorithm set supported by the UE comprises a group security algorithm to be sent according to the security capability information of the UE;
- When the security algorithm set supported by the UE does not comprise the group security algorithm, determining, by the ProSe key management function device, not to feed back a security configuration response message or to feed back a security configuration response message including a security configuration failure indication that does not include the group security key to the UE.

A security configuration method for Device to Device (D2D) communication, comprising:
- sending first information indicating security capability of a User Equipment (UE) to a Proximity-based Service (ProSe) key management function device, the first information being configured to provide a basis for the ProSe key management function device to judge whether a security algorithm set supported by the UE comprises a group security algorithm to be sent and to determine not to feed back a security configuration response message or to feed back a security configuration response message including a security configuration failure indication that does not include the group security key to the UE when the security algorithm set supported by the UE does not comprise the group security algorithm;
- wherein the first information comprises the security algorithm set supported by the UE;
- and
- receiving the security configuration response message fed back by the ProSe key management function device on the basis of the first information;
- receiving the security configuration response message comprising the group security algorithm within a specified time;
- and if the security configuration response message is not received within the specified time, determining that security configuration fails.
3 more elements

- a processor;
- and
- a memory for storing instructions executable by the processor;
- wherein the processor is configured to:
- receive first information indicating security capability of a User Equipment (UE) from the UE;
- wherein the first information comprises a security algorithm set supported by the UE;
- and
- judge whether the security algorithm set supported by the UE comprises a group security algorithm to be sent according to the security capability information of the UE;
- When the security algorithm set supported by the UE does not comprise the group security algorithm, determine not to feed back a security configuration response message or to feed back a security configuration response message including a security configuration failure indication that does not include the group security key to the UE.
6 more elements
A User Equipment (UE), comprising:
- a processor;
- and
- a memory for storing instructions executable by the processor;
- wherein the processor is configured to send first information indicating security capability of the UE to a Proximity-based Service (ProSe) key management function device, the first information being configured to provide a basis for the ProSe key management function device to judge whether a security algorithm set supported by the UE comprises a group security algorithm to be sent and to determine not to feed back a security configuration response message or to feed back a security configuration response message including a security configuration failure indication that does not include the group security key to the UE when the security algorithm set supported by the UE does not comprise the group security algorithm;
- wherein the first information comprises the security algorithm set supported by the UE;
- and
- receive the security configuration response message fed back by the ProSe key management function device on the basis of the first information;
- wherein the processor is further configured to receive the security configuration response message comprising the group security algorithm within a specified time;
- and if the security configuration response message is not received within the specified time, determine that security configuration fails.
