This study describes the integration of thermally assisted switching magnetic random access memories (TAS-MRAMs) in field-programmable gate array (FPGA) design. The non-volatility is achieved through the use of magnetic tunnelling junctions (MTJs) in an MRAM cell. A TAS scheme is used to write data in the MTJ device, which helps to reduce power consumption during a write operation in comparison with...
Failure analysis tools and methods can be used for security purposes as well as the security attack techniques can be used in failure analysis. In this paper, we describe the last results obtained concerning light emission techniques and their use to set up a side channel methodology. From a cryptanalyst standpoint, the light emission could be a potential source of leakage. When studying a specific...
Side channel attacks are known to be efficient techniques to retrieve secret data. In this context, this paper concerns the evaluation of the robustness of triple rail logic against power and electromagnetic analyses on FPGA devices. More precisely, it aims at demonstrating that the basic concepts behind triple rail logic are valid and may provide interesting design guidelines to get DPA resistant...
In this paper we present an adaptive technique to locally adjust the frequency of processing elements on MP-SoC. The proposed method, based on game theory, optimizes the system while fulfilling dynamic constraints. A telecom test-case has been used to demonstrate the effectiveness of our technique. For the evaluated scenario, the proposed technique has obtained up to 20% of latency gain and 38% of...
In the context of FPGAs, system downgrade consists in preventing the update of the hardware configuration or in replaying an old bitstream. The objective can be to preclude a system designer from fixing security vulnerabilities in a design. Such an attack can be performed over a network when the FPGA-based system is remotely updated or on the bus between the configuration memory and the FPGA chip...
The physical implementation of cryptographic algorithms may leak to some attacker security information by the side channel data, as power consumption, timing, temperature or electromagnetic emanation. The differential power analysis (DPA) is a powerful side channel attack, based only on the power consumption information. There are some countermeasures proposed at algorithmic or architectural level...
