Method and apparatus for providing key management for data encryption for cloud-based big data environments
An approach is provided for key management for data encryption. A key management platform receives a request from at least one client for one or more private keys for decrypting one or more datasets. The one or more private keys are encrypted in at least one key repository associated with at least one server. The key management platform also causes, at least in part, an authentication of the request using one or more secure credentials of the at least one client, the at least one server, or a combination thereof. The key management platform further causes, at least in part, an authorization of the at least one client to determine whether the at least one client is authorized to access the one or more private keys based on the authentication. The key management platform further causes, at least in part, a decryption of the one or more private keys using at least one master key based on the authorization.
