hardware based attacks classified by hardware parts
fault tolerance injection
Globally
side channel attack
observing, collecting, and then analyzing the information leakages in the device during processing.
Power Attacks
power consumption varies depending on the code instruction being processed in the device .. so measuring and analyzing this consumption variation can permit us to extract sensitive informations
detection
Mitigation
Electromagnetic (EM) Attacks
analyzing the electromagnetic emissions from the device during operation .. and needs electroM measurmnet probe
Timing Attacks
execution timing somtimes dependant on the data inputs based on the diffrent exec paths
Cache Attacks
Differential Fault Attacks
fault injection\
physical attack injecting fault inthe system with precision to make a change in the system that bypass sec featires ot m nalicious intents m or extract informations ...
by glitch we mean injecting a short lived fault in the system a sudden change in the system that my break the device but with precision we can get what we want
ways of injection
clock glitching
les circuits integre partagent un clock qui maximize le delay de propagation selon les 2 edges de clock
tampering of the system clock
by injecting short pulses to the circuit the attacker can inject the fault when a specific instruction is processed
Integrated Circuits have blocks and registers that share the same clock
clocks have 2 edges and data gets transferred between the 2 edges involving a propagation delay that have to be less than the clock time period to be always controlled
electroM injection
laser injection
light amplification by stimulated emission of radiation
SRAM
on SRAM laser exposure is known to cause bit-flips < a phenomenun which is called Single Event Upset SEU
bu tuning the beam's energy level below a destructiive treshHold the target will not suffer any permanent damage from SEU but a hight amount of energy can destroy the circuit
Beams diameter
Wavelength
Amount of emitted energy
impact coordinates
impact moment
exposure duration
voltage glitch
