- **Caution**: 

### Q: What is access control logic in key storage systems?
**A**: Access control logic is the intelligent subsystem that manages authentication, authorization, and audit trails for both physical and digital key access within secure storage systems, typically implemented using semiconductor and PCB technology.

### Q: How does the authorization rule engine work?
**A**: The authorization rule engine processes predefined security policies to determine whether authenticated users or systems have permission to access specific keys, evaluating factors like user roles, time restrictions, and access history before granting or denying access.

### Q: What materials are used in access control logic systems?
**A**: These systems primarily use semiconductor silicon for processing components and printed circuit boards (PCBs) for circuit integration, providing reliable, scalable, and secure hardware foundations for authentication, authorization, and audit logging functions.
