Abstract
Systems, devices, and methods for providing security on a MIL-STD-1553 serial data bus are described herein. Detected anomalies on the serial data bus that are determined to be threats are invalidated.
Claims50
A bus security device that provides security on a MIL-STD-1553 serial data bus, said device comprising:
- a memory, wherein the memory at least contains security rules stored thereon;
- a processing circuit in communication with the memory;
- and
- a transceiver that connects the bus security device to the MIL-STD-1553 serial data bus, wherein the processing circuit is programmed to:
- monitor the MIL-STD-1553 serial data bus in accordance with the security rules stored in the memory;
- and
- if the processing circuit detects an anomaly on the serial data bus that is characterized as a threat by the rules stored in the memory, then the processing circuit causes the transceiver to inject an invalidation signal onto the data bus to counteract the anomaly.
