Extensive Laser Fault Injection Profiling of 65 nm FPGA [PDF]

Journal of Hardware and Systems Security, 2017
Fault injection attacks have been widely investigated in both academia and industry during the past decade. In this attack approach, the adversary intentionally induces computational faults in the security components of the integrated circuit (IC) for deducing the confidential information processed or stored inside the device.

Influence of triple-well technology on laser fault injection and laser sensor efficiency [PDF]

2015 IEEE International Symposium on Defect and Fault Tolerance in VLSI and Nanotechnology Systems (DFTS), 2015
This study is driven by the need to understand the influence of a Deep-Nwell implant on the sensitivity of integrated circuits to laser-induced fault injections. CMOS technologies can be either dual-well or triple-well. Triple-well technology has several advantages compared to dual-well technology in terms of electrical performances.

Testing Feasibility of Back-Side Laser Fault Injection on a Microcontroller [PDF]

Proceedings of the WESS'15: Workshop on Embedded Systems Security, 2015
Laser fault attack platform constitutes a powerful tool for a precise injection of faults into the device, allowing an attacker to carefully adjust timing and position on the chip. On the other hand, the cost of such equipment is high and the profiling time is non-negligible.In this paper, we would like to investigate the practicability of the back ...

Robustness improvement of an SRAM cell against laser-induced fault injection [PDF]

2013 IEEE International Symposium on Defect and Fault Tolerance in VLSI and Nanotechnology Systems (DFTS), 2013
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 ...

Switching Off your Device Does Not Protect Against Fault Attacks

Transactions on Cryptographic Hardware and Embedded Systems
Physical attacks, and among them fault injection attacks, are a significant threat to the security of embedded systems. Among the means of fault injection, laser has the significant advantage of being extremely spatially accurate.

Reproducible Single-Byte Laser Fault Injection

, 2010
This note describes laser fault experiments on an 8-bit 0.35µm microcontroller with no countermeasures. We show that reproducible single-byte faults, often considered unfeasible, can be obtained by careful beam-size and shot-instant tuning.

An Effective Simulation Analysis of Transient Electromagnetic Multiple Faults

Sensors, 2020
Embedded encryption devices and smart sensors are vulnerable to physical attacks. Due to the continuous shrinking of chip size, laser injection, particle radiation and electromagnetic transient injection are possible methods that introduce transient ...

Beware of Insufficient Redundancy

Transactions on Cryptographic Hardware and Embedded Systems, 2022
Fault injection attacks pose a serious threat to cryptographic implementations. Countermeasures beyond sensors and shields usually deploy some form of redundancy to detect or even correct errors.

Adjusting Laser Injections for Fully Controlled Faults [PDF]

, 2014
Hardware characterizations of integrated circuits have been evolving rapidly with the advent of more precise, sophisticated and cost-efficient tools. In this paper we describe how the fine tuning of a laser source has been used to characterize, set and reset the state of registers in a 90 nm chip.
