US Patent:

60818948, Jun 27, 2000

Filed:

Dec 3, 1997

Appl. No.:

8/984608

Inventors:

Steven D. Mann - Stockbridge GA

Assignee:

RVT Technologies, Inc. - Lilburn GA

International Classification:

H04K 100

US Classification:

713188

Abstract:

An apparatus for isolating data receiving entity from a data sending entity includes a first data channel, coupled to the data sending entity, and a second data channel, coupled to the data receiving entity. A data encryption chip decrypts data received from the data sending entity and encrypts data sent to the data sending entity. A processor is programmed to compare a plurality of data words received from the first data channel to at least one data word characteristic of a data virus and to assert a control signal when a data word received from the first data channel corresponds to a data word characteristic of a data virus. An optical isolator is capable of isolating the first data channel from the second data channel when the processor detects a data virus. A controllable power supply is responsive to the control signal from the processor and coupled to the optical isolator, which provides power to the optical isolator only when the control signal from the processor is not asserted.
