Abstract

Aspects of the invention include loading an image of a virtual server onto a boot partition of a trusted execution environment (TEE), wherein a first key is embedded in the image. A second key is received from an end customer of an application. Data is received from an independent software vendor (ISV) of the application, wherein the data includes a third key. The second key and the third key are combined inside the TEE to create a fourth key. An available memory space in an independent memory device is encrypted using the fourth key to create a secure data volume. Encrypted data is stored in the secure data volume.
