ABSTRACT:
A secured network interface unit (SNIU) for providing multi-level security on a network having a plurality of secured and unsecured users including: network interface means for communicating on the network; identifying the source and destination of a message intercepted on the network; determining the security levels of each of the plurality of users; a trusted computing base for determining whether the message, if transmitted to the destination user, will violate security parameters; and, cryptographically encrypting messages sent to, and decrypting messages received from another SNIU affiliated with the destination user.
