Abstract
Multilevel military communications security can be implemented with the notion of masterkeys. 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 masterkey is constructed from a set of service keys from which masterkey is allowed to access. This thesis presents the principles of multilevel security with restricted character translation, data compression, and masterkey implementation.
