Latest Patents

One of his latest patents is titled "Nested independent virtual private networks with shared rekey and consistency services." This invention allows for the first and second nested virtual private networks to share a common rekey service. A first key server generates cryptographic keys and policies for use by gateways of the VPN to encrypt and decrypt data packets. The key server establishes a connection with a second key server to generate second cryptographic keys and policies independently of the first key server for use by encryption units of a second VPN that operates independently of the first VPN. The first key server refreshes the first cryptographic keys in the first VPN gateways using a common rekey service and cooperates with the second key server to refresh the second cryptographic keys in the second VPN encryption units.

Another significant patent is "Sequence number resetting for synchronizing transfers in a digital network." This invention provides a system and method for re-synchronizing or resetting packet sequence numbers. It allows a sender to send packets with a special sequence number pattern to cause convergence of the sequence numbers on the receiver side. In a preferred embodiment, no explicit routing protocol-based sync-up between the sender and receiver is required. This invention can provide for a maximum drop of two packets regardless of network bandwidth or processing power, and resynchronization can be achieved with minimal packet loss.
