| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In recent years, with the increase of VLSI integration, LSI design companies utilize circuit design information, called IP cores from IP vendors in order to reduce design costs. However, since IP cores are digital data, it is easy to infringe copyright by copying, etc. Therefore, it is important to take measures against copyright infringement of IP cores. As a design method for copyright protection of IP cores, a method called logical encryption has been proposed. On the other hand, efficient attack methods against logical encryption, such as SAT and FALL attacks, have been proposed. Therefore, there is a need for logical encryption that is resistant to these attack methods. In this paper, we propose a method for RTL design based on SFLL-hd, which is resistant to SAT and FALL attacks. For controllers at RTL, we show an algorithm to find a correct key input to realize SFLL-hd. Experimental results show that the proposed method is resistant to the FALL attack. |
