[{"name":"R5-205408","title":"Discussion on NR V2X Authentication test","source":"Huawei, Hisilicon","contact":"Yuchun Wu","contact-id":77331,"tdoctype":"discussion","for":"Information","abstract":"In RAN5-87e meeting, a new WI 5G_V2X_NRSL_eV2XARC-UEConTest was approved and related work such as WP creation, TC definintion\u2026start.\n2.\tDiscussion\nTo enable NR V2X PC5 service, UE have to firstly initiate the PC5 unicast link establishment procedure and pass the authentication procedure between initiating UE and target UE before complete the PC5 unicast link establishment procedure successfully. However, according to following text of TS 33.536, the authentication method maybe defined outside 3GPP and we don\u2019t know which authentication method to be tested yet. [..]\nWe can think of two options:\nOption 1: Deactive the signalling integrity protection, then according to above text, The key establishment procedures in this clause shall be skipped. Thus no need to test the NR V2X authentication.\nOption 2: Study which authentication method is most likely to be used by V2X service and design RAN5 V2X TC based on that.\nBy Option 1, we can run other V2X procedures and related test even without run the Authentication Procedure. However, the cons are that we lose test coverage. \nFor option 2, we need to study and reach agreement on which Authentication Method to be used by V2X test, for example, based on RSA algorithms. We may need to set at least 3 sets of security parameters for UE-1, SS_UE-1 and SS_UE-2 respectively.\nSummary\nIn this paper we bring up the issue of NR V2X Authentication test and share some initial thought of two options of this test. Companies interested in this issue are welcomed to share their view and hopefully, we could continue the discussion and reach agreement as early as possible.","secretary_remarks":"","agenda_item_sort_order":563,"ainumber":"6.3.16.8","ainame":"Discussion Papers \/ Work Plan \/ TC lists","tdoc_agenda_sort_order":54080,"status":"noted","reservation_date":"2020-10-28 01:59:50","uploaded":"2020-10-31 06:44:37","revisionof":"","revisedto":"","release":"Rel-16","crspec":"","crspecversion":"","workitem":[{"winame":"5G_V2X_NRSL_eV2XARC-UEConTest"}],"crnumber":"","crrevision":"","crcategory":"","tsg_crp":"","lsreplyto":"","lsto":"","Cc":"","lsoriginalls":"","lsreply":"","link":"https:\/\/www.3gpp.org\/ftp\/TSG_RAN\/WG5_Test_ex-T1\/TSGR5_89_Electronic\/Docs\/R5-205408.zip","group":"R5","meeting":"R5-89-e","year":2020,"uicc_affected":null,"me_affected":null,"ran_affected":null,"cn_affected":null,"clauses_affected":null,"crsinpack":null,"crsinpacknumber":0},
