A self-modifying code changes its appearance when it is executed. However a typical embedded microcontroller prohibits a code from changing the contents of the instruction memory during execution. To apply the self-modification based tamper-resistance enhancement methods for codes to be executed on such an embedded microcontroller this paper develops a \"simulation\" technique. The output code consists of an \"interpreter\" part to be located in the instruction memory and an \"intermediate code\" part to be located in the data memory. In addition, for a microcontroller with the von Neumann memory architecture the speed overhead of the tamper-resistance enhanced code against its original version becomes small compared to the conventional self-modifying code located wholly in the instruction memory.","subitem_description_type":"Other"}]},"item_18_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"676","bibliographic_titles":[{"bibliographic_title":"コンピュータセキュリティシンポジウム2012論文集"}],"bibliographicPageStart":"669","bibliographicIssueDates":{"bibliographicIssueDate":"2012-10-23","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"3","bibliographicVolumeNumber":"2012"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2025-01-18T23:37:43.442301+00:00","id":86724,"links":{}}
