GEVS EMI requirements were reviewed and revised over a one year period by the GSFC Electromagnetic Compatibility (EMC) Working Group, using MIL-STD-461F [4] as a starting point and incorporating appropriate tailoring to address the specific needs of GSFC platforms.

Faulting an equipment is a mean for a malevolent attacker to extract secret information. Compared to other fault injection setups, those based on EMC tests provide three advantages: non-invasivity, absence of synchronization, and frequency selectivity. This injection technique therefore allows the attacker to perform analysis with little knowledge of the targeted equipment. To assess the potential of this attack, a characterization of its effects is needed. This is the purpose of this paper. More precisely, our contributions are twofold: First of all, we observe that the faults are reproducible. Second, we show that the fault model is compatible with known attacks.","PeriodicalId":197346,"journal":{"name":"2012 IEEE International Symposium on Electromagnetic Compatibility","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125410778","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 method starts from an accurate computation of the differential line's per unit of length transmission line parameters, adopts a parameterized macromodeling scheme, and invokes the so-called stochastic Galerkin method (SGM). Parameter variability of the line itself and of the terminations are studied and compared to a traditional Monte Carlo (MC) approach, as such demonstrating excellent accuracy and efficiency of the proposed new technique. For the first time, an SGM is constructed for and applied to differential on-chip interconnects, and it is illustrated that this novel stochastic modeling strategy is very well suited to analyze common-mode noise induced by random imbalance of the line's terminations.","PeriodicalId":197346,"journal":{"name":"2012 IEEE International Symposium on Electromagnetic Compatibility","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115063858","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 electromagnetic environment of the chamber was simulated using a previously introduced method that samples the plane wave spectrum of the random fields at fixed incidence angles determined from spherical sampling theory. The sampling scheme gives excitation fields that have ideal statistics over the volume occupied by the equipment under test (EUT) while reducing the computation time over traditional approaches. A refinement of the technique has been introduced that exploits the reciprocity principle to further reduce the computational load when simulating electromagnetically large EUTs with a limited number of test points of interest. Up to 1000 000 samples of the random chamber fields were considered. The simulations show that the current coupled onto a wire that is partially shielded by a conducting box with a large aperture exhibits strong resonances. The resonant frequencies appear to be determined mainly by the box dimensions, with aperture resonances also contributing. Statistical testing shows that the induced wire currents follow an ideal Rayleigh distribution independent of the frequency of the excitation.","PeriodicalId":197346,"journal":{"name":"2012 IEEE International Symposium on Electromagnetic Compatibility","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127891501","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}
