WebOct 6, 2024 · We demonstrate how a targeted bitstream modification can seriously weaken cryptographic algorithms, which we show with the examples of AES and 3-DES. In this paper, we propose an automated bitstream Trojan detection framework, which utilizes bitstream reverse engineering for detecting hardware Trojans. We make several assumptions for our proposed approach as follows: 1. 1. We assume the bitstream is not encrypted. This is a valid assumption as in many … See more The overall method is shown in Fig. 1. The idea is to convert a bitstream (with or without Trojan) to a layout level representation and … See more We partition the data in a per tile style, as tiles are the smallest building blocks of the FPGA. Because tiles of the same type contain the same resources, we start with the assumption that they exhibit the same mapping of … See more
