Abstract:Abstract:The paper proposes the use of digital watermark based authentication for intrusion detection in IEC 61850-automated substations. The watermark can be embedded into the Least Significant Bits of the measurements without visible deterioration in precision. When Intelligent Electronics Devices gets measurements, the watermark in the measurement can be retrieved to determine whether it has been attacked and detect malicious intrusion. The proposed approach is appropriate for the time critical and resource… Show more
