Abstract
A resource in unencrypted form and a wrapped key are received in a request from an application server system and at a key server system. The wrapped key includes a resource encryption key and a user identifier that have been encrypted using a master key. The user identifier identifies a user that is permitted to use the resource encryption key to decrypt the resource. The request does not include the user identifier. The wrapped key is decrypted to access the resource encryption key. The resource in unencrypted form is encrypted into an encrypted resource with the resource encryption key. The encrypted resource is sent to the application server system.
