Multilevel Security with Data Compression and Restricted Character Set Translation
Chien C. Tsai · Calhoun: The Naval Postgraduate School Institutional Archive (Naval Postgraduate School) · 1992
Multilevel military communication security can be implemented with the notion of master keys. Naval message traffic is transmitted with restricted character set and optionally files are compressed. Both character translation and data compression can be used as add-on data encryption. A master key is constructed from a set of service keys from which master key is allowed to access. This thesis presents the principles of multilevel security with restricted character translation, data compression, and master key implementation.
