Abstract
An electrical system includes a signal security detection system performing a method of determining a security of an interconnect. An interconnect extended between a first device and a second device. The interconnect has at least one conductive pathway aligned along a direction between the first device and the second device. A light source is configured to transmit a light through the interconnect and an optical detector is configured to receive the light passing through the interconnect. A processor records a first optical signature of the interconnect based on the light received at the optical detector at a first time, records a second optical signature of the interconnect based on the light received at the optical detector at a second time, and validates the second optical signature against the first optical signature to determine a security of the interconnect.
