Abstract(in English) As our information society has further developed, the widespread use of personal electronic devices like smartphones and tablets as informational terminals has become universal. A necessity for this type of social system to be sufficiently functional involves ensuring information security through the protection of personal privacy and reliable and secure e-commerce. Information terminals are composed of a plurality of hierarchies, and to ensure security, implementation must be conducted vertically from the application layer down to the physical layer. Because individual layers generally operate by relying on the layers underneath them, a vulnerability in the hardware, which is the portion underlying the information system, can severely weaken security. Thus, ensuring hardware security is critical. Hardware vulnerabilities that can be exploited to circumvent security can be broadly divided into the categories of those that come from when electromagnetic information is generated through information processing inside a device, those caused through the application of devices that intentionally cause electromagnetic disturbances, and those that are the result of the system being reconfigured through deliberate modification of the electrical and electronic circuitry. In this talk, we focus on information security with regard to electromagnetic information leakage as it relates to hardware security (electromagnetic information security), and our subject device is tablet terminals with which the presence of a threat will be made apparent by using electromagnetic waves to steal on the display (EM display stealing). We will also consider, with regard to these tablets, methods and mechanisms for remedying this threat of having a display screen image being stolen electromagnetically.
