What are some case studies on revocation lists?

Revocation lists are used in various fields, such as digital certificates and licenses. One notable case study is the use of revocation lists in public key infrastructure (PKI) to manage compromised certificates.

Can you explain how revocation lists work in PKI?

In PKI, a revocation list is a list of certificates that have been revoked before their expiration date. This ensures that any compromised or no longer valid certificates are not trusted.

What are the challenges associated with maintaining revocation lists?

Challenges include ensuring timely updates, managing the size of the list, and ensuring that all parties have access to the most current version.

Are there any real-world examples of revocation lists causing issues?

Yes, there have been instances where delays in updating revocation lists led to security vulnerabilities, allowing unauthorized access.
