Which encryption technique connects the instance to the encryption instance responsible for all crypto operations?

The proxy encryption technique serves as an intermediary between the client and the encryption services responsible for handling cryptographic operations. It operates by forwarding data to the encryption instance, which then performs the necessary cryptographic processes before returning the encrypted or decrypted data back to the client. This approach allows for centralized management of encryption keys and policies, enhancing security by separating the data processing from the encryption function itself.

Using a proxy for encryption helps streamline operations and provides a layer of abstraction, which can be crucial for maintaining security protocols and ensuring compliance with various regulatory standards. In cloud environments, where data access and management can be complex, utilizing a proxy can simplify the interaction between users and the encrypted resources, promoting efficient security practices.

In contrast, while external management and server-side strategies do involve encryption, they do not specifically describe the connection mechanism between the instance and the encryption services like the proxy does.
