Latest Patents

One of his latest patents is an Integrated VPN/Firewall System. This invention encompasses systems, devices, and methods related to network firewalls and VPN gateways. It is designed to control and secure access to networks. The integrated system includes a policy engine module, a switch module, a cryptographic engine module, and flow engine modules. Each flow engine module receives Data Transmission Units (DTUs) from either side of the system. The DTUs are compared to entries in both a listening table and a flow table, which consist of characteristics of DTUs expected to arrive for specific flows. The policy engine is responsible for making entries in these tables, with listening table entries denoting flows potentially allowed by policy, while flow tables correspond to flows already permitted between computers on opposite sides of the firewall system.

Another significant patent is a System for Inverse Multiplexing Analog Channels. This bi-directional data communication system utilizes inverse multiplexers to transmit and receive data at high speeds over regular analog channels. The inverse multiplexer splits a high-speed digital signal into low-speed digital signals, which are then input to analog modems. These modems modulate the low-speed digital signals into low-speed analog signals for transmission over the public switched telephone network. At the remote end, the data carried by the analog channels is reverse inverse multiplexed back into a high-speed digital signal.
