Description: A revocation token is a mechanism used in public key infrastructure (PKI) to indicate that a digital certificate has been revoked and is no longer valid. This token acts as a warning signal for systems and users that trust the certificate, allowing appropriate measures to be taken to prevent its misuse. Revocation tokens are essential for maintaining the integrity and security of digital communications, as they ensure that certificates that have been compromised or are no longer needed are not used to authenticate identities or encrypt information. In practice, these tokens are managed through certificate revocation lists (CRLs) or by using protocols such as the Online Certificate Status Protocol (OCSP), which allow for real-time verification of a certificate’s status. The implementation of revocation tokens is crucial in environments where security is a priority, such as in digital communications and data protection. Without an effective revocation system, compromised certificates could continue to be used, potentially leading to security breaches and loss of trust in digital authentication systems.
