Connected Car OTAC is a digital key authentication solution designed for vehicle access and car-sharing services. It addresses the limitations of systems that require active network connections by operating in environments with weak or no signal, such as underground garages or remote locations. The system uses One-Time Authentication Code (OTAC) technology to generate a dynamic digital key locally, enabling authorized individuals to access a vehicle regardless of its or the driver's network connectivity status.
To mitigate cyber threats and unauthorized access, the solution provides robust authentication mechanisms. It integrates into automotive systems via SDK or API and supports multi-factor authentication and secure Bluetooth communications. The technology utilizes a trusted algorithm, hosted in a Trusted Execution Environment (TEE), to enable secure key sharing with expiration limits for multiple users. This allows owners to grant temporary access to individuals like family members or rental customers without relying on continuous internet connectivity.
