Logical operations enable features such as multi-factor authentication, where multiple conditions must be true before granting access. For instance, an AND gate ensures that both fingerprint and PIN verification are successful, providing layered security.
4. From Basic Gates to Complex Security Protocols
a. Building complex decision trees and authentication protocols using combinational and sequential logic
Decision trees in security systems, such as multi-step authentication, are constructed using combinational logic for immediate decisions and sequential logic for processes requiring memory, like tracking login attempts. These structures enable robust security protocols that adapt to various scenarios.
