Side Channel Attack on 8051 Microcontroller

Launching a Power Analysis Side-Channel Attack (SCA) involving predicting the contents of a register within an 8051 (AT89S52) microcontroller. This prediction is made possible by repeatedly executing the same instruction with various data inputs and monitoring the power consumption patterns using an Oscilloscope. Power traces are analyzed using machine learning techniques to forecast the data after noise reduction. The underlying concept of this method is that a microcontroller's power usage is influenced by two factors: the operations being performed, and the data being processed. By keeping the instruction constant, any variation in power consumption is attributed solely to the differences in the data being handled.
