Latest Patents

One of his latest patents is titled "Key management for encrypted packet based networks." In this innovation, a key management center is utilized to distribute cryptographic keys for both switched virtual circuits and permanent virtual circuits. The methods disclosed in this patent allow the key management center to communicate directly with data encryption and decryption devices, even when they operate in a transparent mode. This is achieved by balancing link counters with calls to fictitious addresses and using interrupt packets transferred between the data terminal equipment and the decryption devices. In the case of permanent virtual circuits, the MAC of the last packet transmitted under the old cryptographic key is exchanged to synchronize the key change.
