Recently, the concern about information leakage in the display image caused by the electromagnetic noise has increased from the aspect of information security. In the present study, the information leakage of input button key operations on touch screen monitors was investigated experimentally in the reconstructed display image using the received electromagnetic noise. The experimental results revealed that the touched button image on the touch screen monitor can be identified in the reconstructed display image. In addition, the information leakage origin was discussed based on the reconstruction principle of the display image.","PeriodicalId":201448,"journal":{"name":"2010 IEEE International Symposium on Electromagnetic Compatibility","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116930093","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The 180 × 180 µm2-size on-chip shielded loop probe we developed was applied to scan the magnetic near field on the LSI and clarified that the magnetic filed is strong not only on the targeting cryptographic circuit. Such a detailed map was depicted for the first time for cryptographic LSI. Then the differential electromagnetic analysis (DEMA) was performed with the shielded-loop probe (1000 × 500 µm2, CP-2S, NEC). All the BITEs of 16-BYTEs long secret key are decrypted by using only 1×104 waveform data in case the waveform is measured closely to the cryptographic circuit whereas the error rate does not converge to zero until the waveform number reaches 3×104 if the data were extracted far away from the circuit. As the countermeasure against DEMA, 25µm thick magnetic film (µr=50 at 1MHz, NEC Tokin Co, type E25) was attached on top of bare LSI chip to suppress magnetic field intensity by 6 dB, which can be a good candidate to protect cryptographic LSI from side channel attack.","PeriodicalId":201448,"journal":{"name":"2010 IEEE International Symposium on Electromagnetic Compatibility","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117179538","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Carbon nanotube cellulose nanocomposite (CNTCNC) provides a novel material as an alternative to traditional metal-based shields for EMI shielding.

Significant improvement in shielding effectiveness in stacked CNTCNC layers is noteworthy.

The frequency-domain distribution of current density along radial direction of the bundle is utilized to obtain the expressions of the skin depth and the effective impedance.

Such emissions can be looked at under two aspects: the emissions might interfere with other equipment in the vicinity causing potential malfunction (EMC aspect), or might be considered with regard to human exposure (EMF aspect). Limitation of such emissions related to the EMC aspect is part of EMC activities and is mostly due to the need to protect radio services from being interfered. Applicable limits depend on the type of equipment under concern and of the locations where equipment is intended to be operated. However, more and more such emissions are looked at also under a human exposure point of view within the frame of EMF regulations. As both aspects deal with entirely different objective targets consequently different limits, different measurement procedures and different assessment methods are to be applied. This could mean in practice that basically two kinds of measurements have to be carried out. This paper introduces an approach how to use results obtained by means of EMC measurements for the purpose of EMF assessments. As an example for an assessment the EMC data in the frequency range between 30 MHz and 230 MHz are used as part of an EMF assessment.","PeriodicalId":201448,"journal":{"name":"2010 IEEE International Symposium on Electromagnetic Compatibility","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127011113","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
