What is certification authority or root private key theft?

A certification authority (CA) is a trusted entity that issues digital certificates which verify the identity of individuals and organizations. A root private key is a key used by a CA to sign the digital certificates it issues.

Theft of a root private key would be a serious security concern, as an attacker who obtains the root private key could use it to issue fraudulent digital certificates.

This could allow the attacker to impersonate other individuals or organizations and intercept and decrypt secure communications.

If a root private key is stolen, the CA should revoke all the certificates and issue new ones. This process is known as a root key rollover.

CAs must have robust security measures to protect the root private key from theft and plan to respond to a key compromise.

This includes regular key replacement, secure storage using a FIPS 140-2 Level 3 certified hardware security module (HSM), access controls, monitoring, and incident response plans.
