Patent number: 11104300Abstract: Remote devices have replaced keys as a means to access a secure feature of a vehicle. Remote door locks, starters, climate control, trunk openers, etc., have allowed vehicles to be more welcoming and easier to use. However, such functions often rely on radio frequency transmissions that can merely relay signals coming from an authorized device that may allow a nefarious user to access the vehicle or contents therein. By encoding sequence numbers and timestamps within an exchange, a vehicle may determine that an authorized user is too far away to be granted access to the secure feature, thereby denying access to the nefarious user implementing a relay attack on the vehicle.Type: GrantFiled: July 1, 2019Date of Patent: August 31, 2021Assignee: NIO USA, Inc.Inventors: Yongbum Kim, Qiyan Wang, Jerry L. Petree, Samir Agrawal, Sandeep Dhull, Luna Chen, Jamie P. Carlson

Publication number: 20180212967Abstract: When operating these different environments, the infrastructure of and around a vehicle should be secure to prevent unauthorized and possibly malicious access to the vehicle and the systems therein. To obtain this security, the various systems and components of the vehicle can utilize certificates to authenticate and authorize users as well as equipment and/or components interfacing with the vehicle. According to one embodiment, a portable compute device or tool with internet access can be used in any one or more environments to transport certificates used to support secure connectivity for vehicle systems in a state where the vehicle may or may not have immediate internet access. This tool can also provide various service functions in these different environments. These functions can include performing diagnostics, updating firmware images, collecting log and other data from the vehicle, etc.Type: ApplicationFiled: January 25, 2017Publication date: July 26, 2018Inventors: Abraham T.
