| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Relays are used in many electrical and electronic devices, including switches and sensors. Some relays are electromagnetic relays, which switch circuits open and closed by operating the contacts with electromagnets. An attacker could illegally connect the contacts by applying a strong magnetic field to the electromagnetic relay and manipulate the system. Although this type of attack has the potential to pose a significant threat, there have been no explicit examples of intentional malfunctions caused by magnetostatic fields from a security perspective. In this report, we show clearly that electromagnetic relay malfunctions can be caused by the use of strong magnets even from outside the equipment containing the relay, and discuss attacks using static magnetic fields on electromagnetic relays and countermeasures against them. | |
