Patent number: 10320772Abstract: The present invention is directed to solve a problem that time is required for a process related to verification of a public key certificate of a message sender. An in-vehicle device mounted on a vehicle has a memory for holding information of a device which failed in verification of a public key certificate. At the time of performing communication between vehicles or between a vehicle and a roadside device, a check is made to see whether or not information of a device included in a message transmitted matches information of a device which failed and held in the memory. When the information matches, verification of a public key certificate is not performed.Type: GrantFiled: March 31, 2017Date of Patent: June 11, 2019Assignee: RENESAS ELECTRONICS CORPORATIONInventors: Eriko Ando, Takashi Kawauchi, Toru Owada

Patent number: 9601016Abstract: A communication system (10) includes a certificate authority (100) for performing authentication, a roadside device (110), a vehicle-mounted terminal (120), a first server (130), and a second server (140). The vehicle-mounted terminal transmits its position information to the first server. The certificate authority acquires information about a vehicle-mounted terminal likely to appear according to place and time from the first server. The certificate authority allows the second server to verify validity of a certificate for a vehicle-mounted terminal acquired from the first server. The certificate authority generates a first list of vehicle-mounted terminals having valid certificates and a second list of vehicle-mounted terminals having invalid certificates according to place and time based on a verification result. The certificate authority transmits the first and second lists to the roadside device and the vehicle-mounted terminal.Type: GrantFiled: August 18, 2015Date of Patent: March 21, 2017Assignee: Renesas Electronics CorporationInventors: Eriko Ando, Ken Naganuma, Toru Owada

Patent number: 9432197Abstract: An authentication method is provided which is capable of performing message authentication within an allowable time regardless of the magnitude of the number of messages and performing message authentication high in accuracy within a range for which the allowable time allows. Upon transmission by wireless communications with another mobile or a fixed station, a message authentication code of communication data and a digital signature are generated (S200 and S300). The generated message authentication cod and digital signature are transmitted with being added to the communication data. Upon reception, whether authentication should be done using either one of the message authentication code and the digital signature included in received information is determined according to its own state for the authentication (S400 and S500). This state includes, for example, a load state of a central processing unit or the like that performs an authentication process.Type: GrantFiled: February 22, 2011Date of Patent: August 30, 2016Assignee: RENESAS ELECTRONICS CORPORATIONInventors: Ken Naganuma, Toru Owada, Eriko Ando

Publication number: 20160078761Abstract: If identification information is updated periodically, there is such a problem that when another vehicle is receiving driving support based on transmitted identification information of an own vehicle, if the identification information of the own vehicle is updated, the operation of driving support using the identification information becomes unstable because another vehicle can no longer identify the own vehicle. A mobile terminal mounted on a vehicle determines whether or not transmission control of identification information is necessary after determining the possibility of identification information misuse, determining the effect by controlling transmission of identification information, and determining the magnitude of adverse influence on the safe driving support service.Type: ApplicationFiled: November 23, 2015Publication date: March 17, 2016Inventors: Eriko Ando, Takashi Kawauchi, Toru Owada
