Explain why secure authentication matters in enterprise systems.
Section 1: Overview of the System
Introduce the components: User, Smart Card, CA, CAS++ Server.
Mention that the goal is to authenticate the user securely.
🔹 Section 2: Step-by-Step Breakdown (Refer to the image)
Explain each of the 6 steps in the diagram:
User requests a certificate from CA.
Smart Card is released.
Certificate and user credentials sent to CAS++.
CAS++ requests validation from CA.
CA returns whether it's valid or not.
If valid, CAS++ issues Ticket Granting Cookie (TGC).
🔹 Section 3: Why It’s Secure
Role of encryption
Smart card security
TGC mechanism
🔹 Section 4: Real-World Usage
Enterprise login systems
Military, government, or bank authentication systems
🔹 Conclusion:
Summarize the importance of PKI, certificates, and smart cards in modern secure systems.
