Requirements for a Need-to-Know (NTK) architecture. Revision 1

Purpose of this document is to present the requirements for a system architecture which can be used to transfer and access information in environments where the separation of information on the basis of need-to-know must be maintained. Such an architecture will allow users to easily retrieve information objects from single sources rather than to store local copies, thereby improving access control and reliability of information. The requirements were developed to meet the need-to-know requirements for a number of DOE initiatives, including weapons data archiving, ASCI, ADAPT, ES, and AM-NII
