  • High assurance data tagger for I/O feeds
    Patent number: 8161281
    Abstract: The present invention is a method and system for high-assurance data tagging for input/output feeds. The method may include executing a high-assurance tagging application on a microprocessor (e.g., the microprocessor being designed for use in a high-assurance embedded system). Further, the method may include analyzing a message with the high-assurance tagging application and generating and attaching a tag to the message. In addition, the method may include binding the tag to the message by applying a message authentication scheme and providing a mechanism for down-stream applications to identify information about data included in the message by reference to the tag.

  • System and method for multi-level security on a network
    Patent number: 7607011
    Abstract: A method of communicating information in a system having multi-level security requirements includes receiving a packet having unencrypted data, routing the packet to a host, and processing the packet at the host such that data from the packet is maintained in the protected address space associated with the host. The host includes a number of virtual hosts, each having a unique internet protocol (IP) address, a protected address space, and a protocol stack.

  • Secure gateway/router
    Patent number: 7607167
    Abstract: The present invention is directed to a secure gateway/router system and method for allowing a MLS network which simultaneously contains data of multiple security levels to interface with one of several MSLS networks which is configured to maintain data with a single security level. When the data is within the secure gateway/router system, the separation of the data by security levels, as it was received from the MLS network, is maintained by routing the data to a designated security level network. Secure gateway/router system includes several network interface units. Each network interface unit is configured to interface within a single MSLS network. Each MSLS software partition has a single and simple function to perform in maintaining separation of security levels and provide the data to the network interface unit configured to interface within the designated security level network.
