Laser-induced fault effects in security-dedicated circuits

Abstract

HAL is a multidisciplinary open access archive for the deposit and dissemination of scientific research documents, whether they are published or not. The documents may come from teaching and research institutions in France or abroad, or from public or private research centers. L'archive ouverte pluridisciplinaire HAL, est destinée au dépôt et à la diffusion de documents scientifiques de niveau recherche, publiés ou non, émanant des établissements d'enseignement et de recherche français ou étrangers, des laboratoires publics ou privés.

A Fast Characterization Method for Semi-invasive Fault Injection Attacks

“…Such attacks are aimed at disrupting the normal memory operation through preventing changes of the memory contents. Van Woudenberg et al investigated optical fault injection on secure microcontrollers and concluded that the presence of countermeasures makes the attack more difficult but still possible [8,9]. Note, while being very powerful, optical fault injection attacks are usually considered very complex due to the high costs of equipment and the preparation of the sample.…”

Fault analysis in cryptography

“…The only difference in stealing physical goods and stealing information is that theft of data still leaves the owner in possession of that data. Passive information attack is thus more dangerous than stealing of goods, as information theft may go unnoticed by the owner [12]. Active Attacks-In this attack attacker does some process on information so that he can change some information In For example,…”

Laser-Induced Fault Effects in Security-Dedicated Circuits

“…We will focus here on fault-based attacks aiming at retrieving some confidential information such as a private cryptographic key stored in the circuit. One of the most efficient techniques to induce faults in a circuit is to use a laser [1].…”
