Abstract

See full text

Controlling access to disseminated messages includes implementing one or more key management policies that specify how various encryption keys are maintained and in particular, when encryption keys are made inaccessible. Deleting a particular key renders inaccessible all copies of messages, known or unknown, associated with the particular key, regardless of the location of the associated messages. A message may be directly or indirectly associated with a deleted key. Any number of levels of indirection are possible and either situation makes the message unrecoverable. The approach is applicable to any type of data in any format and the invention is not limited to any type of data or any type of data format.
