Abstract
An encryption switch which is used in a cloud environment to secure data on the LUNs used by the clients. A client provides a certificate to the cloud service. The encryption switch develops a cloud crypto domain (CCD) as a secure area, with the data at rest on the LUNs encrypted. The encryption switch develops a master key for client use in the CCD, which is provided to the client encrypted by the client's public key. Data encryption keys (DEKs) are created for each LUN and provided to the client. The DEKs are stored in a key vault by the client for use if needed. The cloud service provisions a client VM to be used with the encrypted LUN and develops a nexus between the LUN and the client VM for the encryption switch to use in data operations. The client communicates through the client VM to access the LUN.
