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. Signaling methods are used to notify virtual machine instances of serialization events in order to prevent keying material from being stored persistently.
