5 Application
5.1 General In a cryptographic system it may be desirable to generate keys using a constructive process, where keys are derived from system-specified control information, as well as secret random data. It may also be desirable to attach a “key usage vector” to each key, defining how the key may be used.
5.2 The Use of Constructive Key Management With Constructive Key Management (CKM), key components, called splits, shall be generated with a random or pseudorandom number generator. Each of these splits shall be given a name, called a label, that provides some meaningful information to the sender, and allows the sender to direct the encrypted object to a selected set of end-users. The working key shall be constructed by combining the addressee splits with the system generated and controlled splits. Thus, with CKM it is possible to create a group key for a particular set of end-users. Other recipients, who are not members of the group, will be unable to re-construct that particular group key.
