Robustness evaluation and improvements under laser-based fault attacks of an AES crypto-processor implemented on a SRAM-based FPGA

Programmable devices like SRAM-based FPGAs, thanks to their low cost and high flexibility, are increasingly used for security applications; the mam drawback is their configuration memory, sensitive to perturbations. Symmetric cryptosystems are highly vulnerable to fault injections [1], but very few papers have reported laser-based fault attacks onto a secure implementation on a SRAM-based FPGA.
