In this work, we present a low-cost fault injection setup which is capable of producing localized faults in modern 8-bit and 32-bit microcontrollers, does not require handling hazardous
Two different optical setups were used throughout the experiments: Setup 1 for creating the OBIC 1 image and Setup 2 for fault injection. The main difference is that Setup 1 is equipped with a contin
Physical attacks pose a significant threat to the security of embedded processors, which have become an integral part of our daily lives. Processors can
Fault injection attack (FIA) is a technique that targets the hardware itself to create unexpected behaviors in systems, often with catastrophic consequences.
Fault injection is a technique used in computer science to evaluate the dependability of systems. It involves intentionally introducing faults into a system in order to observe its behavior and assess the
If devices are physically accessible optical fault injection attacks pose a great threat since the data processed as well as the operation flow can be
Explore fault injection: its workings, examples, risks, and protective strategies. Dive into understanding and safeguarding systems effectively.
The so-called fault injections aim at inducing a valuable logical fault by a physical disruption. It has been demonstrated that a laser pulse focused on a sensitive part of the die may induce such a logical fault.
This paper presents the essentials of optical injection attacks with a short description of experiments carried out. Most of them were published in
In this section we discuss the fault injection setup we designed to overcome these shortcomings and ad-here to the specifications needed for optical fault injection on modern secure microcontrollers.
In August 2024, Raspberry Pi introduced the RP2350 microcontroller. This part iterates over the RP2040 and comes with
We are commissioning such equipment and plan to use it to explore the potential for fault induction through the rear of the chip using infrared light. We have also obtained access to a suitable X-ray
Laser fault injection is a type of optical fault injection attack that falls under the semi-invasive or noninvasive categories. In a semi-invasive attack, we need to do sample preparation like
In our experiments, we were able to inject repeatable faults into all 4 types of gates with a slight deviation of laser beam output power using 100 and 50 magni cation objective.
In this paper we detail the latest developments regarding optical fault injection on secure micro controllers. On these targets, a combination of countermeasures makes fault injection less than trivial.

Abstract Fault injection attacks (FIA) are a class of active physical attacks, mostly used for malicious purposes such as extraction of cryptographic keys, privilege escalation, attacks on neural network
AI Optical fault injection attacks can compromise smart card security, necessitating robust countermeasures. Phototransistors currently serve as primary light detectors; however, photodiodes
Laser fault injection (LFI) has long been a domain only accessible to labs and research institutions with equipment worth hundreds of thousands of
In the rapidly evolving field of fault injection analysis, laser injection systems revolutionizes the way we approach injection performance, offering
In this work we investigated the sensitivity of radiation-hard JICG shift registers to optical fault injection attacks. In our experiments, we were able to trigger bit-set and bit-reset repeatedly changing the data
We propose a method similar to , i.e., using clever imaging to find target locations for fault injection independently of all other parameters like timing, length, or energy. In contrast to , our method
Flash memory, as a storage medium, is normally featured with high security, and thus often contains sensitive data such as passwords, cryptographic keys and other confidential contents. Optical fault
