Abstract
The present invention is a MILS network system employing functional separation of messages without customized switches. The MILS network system may maintain separation of data while eliminating a requirement of full message encryption. In an embodiment of the invention, a function may be employed whereby a keyed digest of a message is created. The function may receive a message and a key, and may emit a keyed digest value. The key may be representative of a particular level of security, thus promoting the separation of data. Messages may include an embedded keyed digest when sent through a switch to a MILS node. At the MILS node, the keyed digest may be recalculated, if it matches, the message may be passed to a host.
