A. B. C. D.A.
The correct answer is D. Key recovery.
Explanation:
In this scenario, the organization wants to allow a certificate authority to gain access to the encrypted data and create digital signatures on behalf of the user. The data is encrypted using the public key from a user's certificate.
Key escrow and key storage are processes that involve the storage of encryption keys, but they do not allow a third party to access encrypted data and create digital signatures on behalf of the user.
Key revocation is a process in which a user's certificate is revoked if the private key associated with it is compromised or if the user no longer has the right to access the system. This process does not fulfill the requirement of allowing a certificate authority to access the encrypted data and create digital signatures on behalf of the user.
Key recovery is the process of recovering a lost or compromised private key. In this scenario, the certificate authority needs to gain access to the encrypted data and create digital signatures on behalf of the user. To do this, the certificate authority would need to have access to the user's private key. If the user has lost their private key or it has been compromised, the key recovery process can be used to recover it. Once the private key has been recovered, the certificate authority can use it to access the encrypted data and create digital signatures on behalf of the user.
