34、Vehicle-to-InfrastructureV2N Vehicle-to-Network V2P Vehicle-to-Pedestrian V2V Vehicle-to-Vehicle V2X Vehicle-to-EverythingVCF V2X Control Function 4 V2X security architecture V2X service contains three types of vehicular communication services V2V (vehicle to vehicle), V2I (vehicle to infrastructure

35、), V2N (vehicle to network), and V2P (vehicle to pedestrian) for both safety and non-safety aspects. The overall architecture describing LTE enhancements for V2X services is given in TS 23.285 3. Both LTE-Uu based architecture (e.g. eMBMS) and PC5 based architecture are used for supporting V2X servi

36、ces, but they may be used by a UE independently for transmission and reception, e.g. a UE can use eMBMS for reception without using LTE-Uu for transmission. The security for interfaces given in the overall architecture (TS 23.285 3) is provided in clause 6, in detail these are the interfaces between

37、 network entities (clause 6.2), between UE and V2X Control Function (clause 6.3), and between V2X AS and 3GPP system (clause 6.4). Clause 6.5 discusses security of V2X application data. Clause 6.6 is providing details to privacy in V2X services. Note: The V2 interface is not specified in 3GPP TS 23.

38、285 3, thus out of scope also in the present document. 5 V2X security requirements 5.1 General The service requirements for V2X services are specified in 3GPP TS 22.185 2.

39、ease 145.2 Interfaces between network elements The V2X network entities shall be able to authenticate the source of the received data communications. The transmission of data between V2X network entities shall be integrity protected. The transmission of data between V2X network entities shall be con

40、fidentiality protected. The transmission of data between V2X network entities shall be protected from replays. 5.3 Interface between UE and V2X control function (V3) The V2X enabled UE and its HPLMN V2X Control Function shall mutually authenticate each other. The transmission of configuration data b

41、etween the V2X Control Function and the UE shall be integrity protected. The transmission of configuration data between the V2X Control Function and the UE shall be confidentiality protected. The transmission of configuration data between the V2X Control Function and the UE shall be protected from r

42、eplays. The transmission of UE identity should be confidentiality protected on the V3 interface. 5.4 Interface between external provider and 3GPP network (MB2) V2X services use the MB2 interface for GCSE. The requirements to MB2 as listed in Annex N.1.2 of 3GPP TS 33.246 shall apply. 5.5 Security re

43、quirements of V2X application data The V2X system entities should be able to authenticate and verify that the sender of the received data communications was authorized to send the data. The transmission of data between different V2X entities in the V2X system should be integrity protected. The trans

44、mission of data between different V2X entities in the V2X system should be protected from replays. The transmission of data between two different V2X entities in the V2X system should be confidentiality protected if needed for the V2X application. NOTE: Transmission of data includes but is not limit

45、ed to multicast, broadcast, unicast, or geocast. 5.6 Privacy related requirements As specified in 3GPP TS 22.185 2 the following PC5 privacy related requirements apply: Subject to regional regulatory requirements and/or operator policy for a V2X application, the data sent in the PC5 transmission sho

46、uld not allow UE identity to be tracked or identified by any other UE or non-V2X entity beyond a certain short time-period required by the V2X application. Subject to regional regulatory requirements and/or operator policy for a V2V/V2I application, the data sent in the PC5 transmission should not a

47、llow a single party (operator or third party) to track a UE identity in that region. In addition, the following PC5 related requirements are given in the present specification: The identifiers in the V2X messages should minimize the risk of leaking the UE or user permanent identities. UE pseudonymit

48、y should be provided to conceal personal data from attackers. The application layer UE identity in the V2X messages should be protected from eavesdropping.

49、V2X services relying on access networks within the scope of TS 33.401 12, the 3GPP authentication, key agreement, associated subscriber credentials and associated subscriber identities used to access the network should reside on USIM within the V2X enabled UE. For V2X services relying on access networks within the scope of TS 33.402 18, the 3GPP authentication, key agreement, associated subscriber credentials and associated subscriber identities used to access the network should reside on UICC within the V2
