However, the security is delegated to the application layer, which is out of the scope of the 3GPP-layer specification. Hence, we propose a transparent and independent distributed security protocol for C-V2X over the PC5 interface at the RLC-layer based on cryptographic ratchets. Our new proposed security protocol provides authenticated encryption, integrity, forward and backward secrecy. The security procedure can start on the fly as soon as vehicles enter a C-V2X group over the PC5 interface, using the cryptographic credentials of the digital certificate issued for ITS applications. The distributed security protocol supports strong encryption, authentication and privacy regardless of the use case in 5G applications for C-V2X over the PC5 interface., 12th International Workshop on Information Network Design (WIND-2020), in conjunction with 12th International Conference on Intelligent Networking and Collaborative Systems (INCoS-2020), August 31st - September 2nd, 2020, University of Victoria, Canada(新型コロナ感染拡大に伴い、現地開催中止)}, pages = {216--225}, title = {End-to-End Security for Connected Vehicles}, volume = {1263}, year = {2020}, yomi = {ツカモト, カズヤ} }
