The use of embedded block memories (BRAMs) in Xilinx FPGA devices makes it possible to store the T-Boxes that are employed to implement the AES block cipher’s SubBytes and MixColumns operations. Several studies into BRAM resistance to side-channel attacks have been reported in the literature, whereas this paper presents a novel attack based on tampering the(More)

The execution flow of the binary extended Euclidean algorithm (BEEA) is heavily dependent on its inputs. Taking advantage of that fact, this work presents a novel simple power analysis (SPA) of this algorithm that reveals some exploitable power consumption-related leakages. The exposed leakages make it possible to retrieve some bits of the algorithm’s(More)
