Abstract
Organizations maintain and generate large amounts of sensitive information using computer hardware resources and services of a service provider. Furthermore, there is a need to be able to delete large amounts of data securely and quickly by encrypting the data with a key and destroying the key. To ensure that information stored remotely is secured and capable of secure deletion, cryptographic keys used by the organization should be prevented from being persistently stored during serialization operations. If the keys used to encrypt the data have not been exposed during serialization operation, they may be deleted or destroyed enabling the destruction of data encrypted with the keys.
