Device authentication method with restricted memory access
The patent US12045334B2 outlines a method and system for authenticating devices while restricting access to their respective memory areas. The process involves a first device authenticating a second device by generating unique data from both devices. During this authentication, the first device's processor is restricted from accessing certain memory areas, with the authentication circuitry providing dummy data in response to any read attempts. Similarly, the second device's processor faces access restrictions, ensuring that both devices maintain a secure environment during the authentication process. The method emphasizes a Verifier/Prover authentication type and includes provisions for handling both volatile and non-volatile memory areas.
Additionally, the patent describes the architecture of the devices involved, which includes processors, memory, and authentication circuitry. The authentication process is designed to share state information between the devices, enhancing security. The claims also cover the functionality of non-transitory computer-readable media that can configure the authentication circuitry to execute these processes. This includes the ability to interrupt access attempts and generate data necessary for the authentication, ensuring that both devices can securely verify each other while maintaining the integrity of their memory systems. Overall, the patent presents a comprehensive approach to device authentication that prioritizes security through controlled access to memory.
