This paper is the third in a series of papers reporting on the results of protecting the microcontroller executed code against side attacks. The protection consists in randomizing, under the control of a chaotic circuit, of both the clock and the power supply voltage of a microcontroller. The results obtained by this double randomization are compared with the ones obtained with either clock or power...
We propose a method for preventing the power analysis-based reading of instructions executed by a microcontroller. We analyze the operation of a microcontroller system that uses a clock based on a chaotic generator. The purpose of the analysis is twofold: to determine the possibility of clocking a typical microcontroller, like PIC16F84, with a chaotic clock, and to determine the efficiency of securing...
