Low-cost electromagnetic fault injection experiment platform and experiment method

Abstract

The invention discloses a low-cost electromagnetic fault injection experiment platform and experiment method in order to perform electromagnetic fault injection experiment, belonging to the integratedcircuit safety and electromagnetic fault injection fields. The low-cost electromagnetic fault injection experiment platform comprises a self-made electromagnetic pulse generator, a fixed support, anelectromagnetic probe, an XYZ moving platform, a device to be attacked and a signal collection device. A relative position between the electromagnetic probe and the device to be attacked can be regulated through the XYZ moving platform. The self-made electromagnetic pulse generator is utilized to generate electromagnetic pulse of a specific parameter to perform electromagnetic fault injection experiment on a specific position of the device to be attacked, and an experiment phenomenon is observed and recorded through the signal collection device, which prepares for following experiment result analysis. The low-cost electromagnetic fault injection experiment platform is simple in design, low in manufacture cost, easy to operate and good in stability, and lays a foundation to the study of anelectromagnetic fault injection mechanism and a design method of an integrated circuit resisting an electromagnetic fault injection attack.

Description

technical field [0001] The invention relates to the fields of integrated circuit safety and electromagnetic fault injection, in particular to a low-cost electromagnetic fault injection experiment platform and an experiment method. Background technique [0002] With the rapid development of information technology, people pay more and more attention to information security. The fault attack on the encryption circuit poses a great threat to the security of the chip. It injects faults into the chip through a specific experimental device, and then uses cryptanalysis techniques such as differential fault analysis and fault sensitivity analysis to crack its encrypted information [1] . [0003] The physical implementation of the encryption algorithm allows attackers to use side-channel information such as power consumption and electromagnetics generated by the chip during the encryption process to carry out side-channel attacks. Compared with the passive attack method of side chan...
