VEHICULAR DIGITAL KEY SYSTEM, VEHICULAR DIGITAL KEY MANAGEMENT METHOD, VEHICULAR DEVICE, AND MOBILE TERMINAL - A simplified explanation of the abstract
This abstract first appeared for US patent application 18615138 titled 'VEHICULAR DIGITAL KEY SYSTEM, VEHICULAR DIGITAL KEY MANAGEMENT METHOD, VEHICULAR DEVICE, AND MOBILE TERMINAL
The abstract describes a system where a server issues a service key and multiple one-time authentication keys to a mobile terminal for using a designated vehicle. The one-time authentication key is generated based on the service key and has an expiration date. It is consumed when the vehicular device authenticates the mobile terminal as a communication partner, and can be replaced at any time by the mobile terminal.
- Service key issued for using a designated vehicle
- Multiple one-time authentication keys provided to the mobile terminal
- One-time authentication key generated based on the service key
- Key has an expiration date and is consumed upon authentication
- Mobile terminal can replace the key at any time
Potential Applications: - Secure vehicle access and communication - Fleet management systems - Rental car services
Problems Solved: - Ensures secure authentication for vehicle access - Prevents unauthorized use of designated vehicles
Benefits: - Enhanced security for vehicle access - Convenient and flexible authentication process - Improved fleet management efficiency
Commercial Applications: Title: Secure Vehicle Access System This technology can be used in rental car services, transportation companies, and other industries where secure vehicle access is essential. It can improve operational efficiency and enhance customer satisfaction.
Questions about Secure Vehicle Access System:
1. How does the system ensure the security of the authentication process? The system generates disposable authentication keys based on a service key, which are consumed upon authentication, ensuring secure access to designated vehicles.
2. Can the mobile terminal easily replace the one-time authentication key? Yes, the mobile terminal can replace the one-time authentication key stored in the device at any time, providing flexibility and convenience for users.
Original Abstract Submitted
A server issues a service key for using a designated vehicle and a plurality of one-time authentication keys based on a request from the mobile terminal, and distributes the one-time authentication key to the mobile terminal. The one-time authentication key is a disposable authentication key generated based on the service key, and has an expiration date. The one-time authentication key is consumed when the vehicular device authenticates the mobile terminal as a communication partner. The mobile terminal replaces the one-time authentication key stored in the mobile terminal at any time.
