The submission of a revocation request is necessary when what condition occurs?

The correct response relates to situations in which the integrity or security of a cryptographic token is compromised, specifically when a token is damaged such that it cannot be reset or recovered. In Public Key Infrastructure (PKI), a token is often used to store private keys and other sensitive information securely. If the token is damaged and the associated PIN cannot be reset, this may lead to a scenario where the private key cannot be accessed, rendering it unusable.

In this context, submitting a revocation request is a critical step because it formally notifies the Certificate Authority (CA) that the token—and therefore the associated private key—should be considered invalid. This action prevents any potential misuse of the compromised token and ensures that it cannot be used to perform unauthorized actions, thereby maintaining the integrity of the PKI system.

While other circumstances, such as account cancellations or changes in ID, might also prompt a revocation request, the specific scenario of a damaged token coupled with an inability to reset the PIN indicates an immediate security risk that necessitates swift action to protect the integrity of the PKI environment.
