Abstract (in Japanese) (See Japanese page) 
(in English) Advances in optical integrated circuit technologies have contributed the rapid development of optical information infrastructure capable of performing low-latency intelligent processing on communication networks. However, security evaluation, particularly verifying resistance to physical attacks, remains a challenge in the implementation of optical circuits. This work evaluates the resistance of optical cryptographic circuits against laser fault injection attacks. First, based on actual measurements, we demonstrate an attacker can perform optical modulation from outside the chip by irradiating a laser beam to the Mach-Zehnder interferometer (MZI), a key component of optical cryptographic circuits. Next, based on these experimental results, we propose a novel attack algorithm that exploits the implementation characteristics of optical cryptographic circuits and is applicable to general ciphers using S-boxes in their key schedulers. Furthermore, we verifies the effectiveness of the proposed method through numeriacal simulations using the lightweight block cipher PRESENT as an example. The results show that the proposed method can reduce the key search space to a level equivalent to that of conventional analysis on CMOS cryptographic circuits.
