Sensor sentinel computing device
| DWPI Title: System for authenticating data output by sensors in industrial environment, has database system causing time-series signal and validation signal to be retained in relation to one another in non-transitory computer-readable data storage |
| Abstract: Technologies pertaining to authenticating data output by sensors in an industrial environment are described herein. A sensor sentinel computing device receives time-series data from a sensor by way of a wireline connection. The sensor sentinel computing device generates a validation signal that is a function of the time-series signal. The sensor sentinel computing device then transmits the validation signal to a programmable logic controller in the industrial environment. |
| Use: System for authenticating data output by sensors in an industrial environment. Uses include but are not limited to temperature sensor, pressure sensor, scale, voltmeter and flow meter. |
| Advantage: The system allows a sensor sentinel computing device to execute cryptographic function over time-series signal utilizing a cryptographic key to generate an encrypted time-series signal. The system allows an overseer of an operation to determine that an attempt is made to access the sensor sentinel computing device by visually inspecting the tamper-indicating enclosure if a malicious person attempted to gain unauthorized access to the sensor sentinel computing device. The system configures the computing device to pass the time-series signals to the programmable logic controller by a subset of output ports of the computing device. |
| Novelty: The system (100) has a programmable logic controller comprising control logic that compares a first validation signal to a second validation signal to determine validation. A database system (126) causes a first time-series signal and the first validation signal to be retained in relation to one another in non-transitory computer-readable data storage in a database, where the comparison signal causes a message to be delivered to an operator if the comparison indicates that the second validation signal fails to match the first validation signal. |
