What can result from disclosing PKI keys to unauthorized persons?

Disclosing PKI keys to unauthorized persons can lead to significant security breaches as these keys are critical for maintaining the integrity and confidentiality of sensitive information. When keys are exposed, it undermines the very foundation of the PKI security framework, which relies on the trust and confidentiality these keys provide.

The result of such a breach often includes potential reprimand or suspension for the responsible party due to negligence or failure to adhere to security policies. Organizations take the protection of sensitive information very seriously, and any failure to securely manage cryptographic keys can result in disciplinary actions to uphold security standards and deter future occurrences.

In contrast, the other options do not align with the consequences of key disclosure. Increased security protocols and rewards for the subscriber don't directly stem from unauthorized disclosures, while encouragement from management would unlikely follow a significant security breach, as such incidents generally lead to concern and corrective action.
