Authentication System Concept
The built-in authentication microcomputer stores the matching key data and accurately transmits the authentication results.
Security is enhanced by encrypting data transfers between the system and individual components.
Unauthorized access is prevented by the strong anti-tampering function incorporated into the authentication microcomputer.
