Embodiment Construction

[0035] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0036] In order to support the security function of D2D communication, the present invention introduces a logical entity, that is, a security entity (security entity), which is used in wireless communication networks based on mobile communication infrastructure, such as LTE (Long Term Evolution, Long Term Evolution) networks, IMT -Advanced network, WiMAX (Worldwide Interoperability for Microwave Access, Global Microwave Interconnection Access) network, etc., perform D2D communication security functions. This security entity is independent of the security architecture and operation process of the traditional access network and core network. The former is like E-UTRAN (evolved universal terrestrial radio access network, evolved universal terrestrial radio access network), and the latter is like the core network in the LTE system. EPC (Evolved Packet Core, evolv...

Abstract

The invention provides a device and system used for device-to-device secure communication. According to the device and system used for device-to-device secure communication, a first user device determines a second user device to directly communicate with the first user device, a first network device generates secure configuration information of device-to-device communication for the first user device and the second user device which plan to carry out direct communication, and sends the secure configuration information to the first user device and the second user device, and the first user device and the second user device establish direct communication according to the secure configuration information. Compared with the prior art, the device and system used for device-to-device secure communication put emphasis on the secure feature of D2D communication. Besides, due to the fact that device used for the D2D communication can simultaneously support communication via an access link and a D2D link, the secure design of the D2D link does not affect the security of the access link. By means of the secure scheme, the device and system used for device-to-device secure communication can protect data flows from being received by a third party, and enables a receiving party to detect inserting and replacement of data groups.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a technology for secure communication between devices. Background technique [0002] The device-to-device communications (D2D) with mobile communication infrastructure as the underlying architecture aims to realize direct communication between two adjacent devices. This mode of direct communication between devices has huge commercial prospects. [0003] In a traditional cellular network, it is necessary to establish the security of the wireless interface between the base station and the user. For example, in scenarios such as connection establishment, cell handover, or connection reestablishment, security keys are generated by the base station and user equipment respectively. However, in the D2D communication mode, the security of the D2D communication needs to be maintained during the communication process between devices performing D2D communication via the wire...
