Title

Association with Other Related Information

Control

An association may need to be maintained between protected information and the keying material that is used to protect that information. In addition, keys may require association with other keying material (see Section 6.2.1.6 ). Storing the information together or providing some linkage or pointer between the information satisfies the association requirement. Often, the linkage between a key and the information it protects is accomplished by providing an identifier for a key, storing the identifier with the key in the key’s metadata, and storing the key’s identifier with the protected information. The association shall be maintained for as long as the protected information needs to be processed. Section 6.2.3 addresses the use of metadata for cryptographic information.
