In this study, we propose a system that enables users to issue transactions as intended, regardless of whether malware is present, by directly displaying the contents of the transaction with a signature from TrustZone and confirming the trusted information under Trusted UI. Furthermore, we implement the TrustZone using a Raspberry Pi and measure the processing time required to generate a signature for a transaction in the proposed cold wallet.","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":"2024-11-26","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"28","bibliographicVolumeNumber":"2024-SPT-57"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":241453,"links":{}}
