The paper aims at demonstrating experimentally that the tiny Electro Magnetic (EM) coupling between the tip end of a micro-antenna is sufficient to locally and directly inject power into CMOS Integrated Circuits (IC). More precisely, experimental results show that such electrical couplings are sufficient to disturb, with and without removing the IC package,(More)
This paper introduces a low cost near-field mapping system. This system scans automatically and dynamically, in the time domain, the magnetic field emitted by integrated circuits during the execution of a repetitive set of instructions. Application of this measurement system is given to an industrial chip designed with a 180nm CMOS process. This application(More)
This paper presents measurements of pulsed photoelectrical laser stimulation of an NMOS transistor in 90nm technology. The laser power was able to trig the NPN parasitic bipolar Drain/Psubstrate/Source. An electrical model is proposed in order to simulate effects induced by the laser. Results extracted from the electrical simulator are compared to(More)
Implementation attacks are a major threat to hardware cryptographic implementations. These attacks exploit the correlation existing between the computed data and variables such as computation time, consumed power, and electromagnetic (EM) emissions. Recently, the EM channel has been proven as an effective passive and active attack technique against secure(More)

Fault attacks are widely deployed against secure devices by hardware evaluation centers. While the least expensive fault injection techniques, like clock or voltage glitches, are well taken into account in secure devices by dedicated hardware counter-measures, more advanced techniques, such as light based attacks, require huge investments.

Bulk Built-In Current Sensors (BBICS) were developed to detect the transient bulk currents induced in the bulk of integrated circuits when hit by ionizing particles or pulsed laser. This paper reports the experimental evaluation of a complete BBICS architecture, designed to simultaneously monitor PMOS and NMOS transistors, under Photoelectric Laser(More)
This paper presents the design of an SRAM cell with a robustness improvement against laser-induced fault injection. We report the fault sensitivity mapping of a first SRAM design. A careful analysis of its results combined with the use of an electrical model at transistor level of the photoelectric effect induced by a laser permit us to validate our(More)
