We propose a method for pattern generation for built-in self-testing and a class of pattern generators that may have advantages in wearables and portable devices for medical use. The generator is based on generalized binary tent maps. We investigate the capabilities of these maps to produce a wide range of patterns suitable for device testing.
Several matters related to noise design for preamplifiers are presented for very low frequencies, also pointing to issues raised by some circuits in the literature, including those with noise cancelling circuits. The changes in excess noise with temperature are of interest in applications such as wearable, where large variations of temperature can occur.
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...
