Certificate Revocation

Definition ∞ Certificate revocation is the act of invalidating a digital certificate before its scheduled expiration date. This process ensures that compromised or no longer valid certificates cannot be used to verify identity or encrypt communications. It is a critical security measure within public key infrastructure, preventing misuse of credentials.
Context ∞ In the realm of digital assets and blockchain, certificate revocation is relevant for systems relying on traditional PKI components for identity verification or secure communication channels. While many blockchain systems aim for trustless operation, some hybrid models or enterprise solutions may incorporate certificates. News reports might discuss revocation lists or status checks when addressing security incidents or changes in credential management within such systems.
