Abstract
A method and apparatus is provided for distributing a software object from a source to a user. A software object is encrypted with an encryption operation utilizing a long-lived encryption key. It is directed from the source to the user. It is loaded onto a user-controlled data processing system having a particular configuration. A numerical machine identification is derived based at least in part upon the particular data processing system configuration of the user-controlled data processing system. A temporary key is derived which is based at least in part upon the numerical machine identification and the long-lived encryption key. The long-lived key generator is provided for receiving the temporary key and producing the long-lived encryption key. The user is allowed to utilize the temporary key for a prescribed interval to generate the long-lived encryption key to access the software object.
