の閾値電圧の変化に依存して低下することに着目し，電圧変化や漏洩電磁波などのサイドチャネル情報に含まれる信号のスイッチングの影響を抽出・累積することで経年劣化を判別する．具体的には，ARM Cortex-M4 を用いた実験を通して，周波数領域上のサイドチャネル解析で利用される動作周波数周辺および低周波数帯の電圧波形から有効な周波数帯の情報を抽出・累積することで，未使用と劣化したマイクロコントローラを判別できる可能性があることを示す．","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告セキュリティ心理学とトラスト（SPT）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2024-07-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"64","bibliographicVolumeNumber":"2024-SPT-56"}]},"relation_version_is_last":true,"weko_creator_id":"44499"}}
