high-capacity DRAM has improved the performance of computers. On the other hand, a problem called Rowhammer, in which unintended bit flips occur in DRAM, has been pointed out. There are many attacks using Rowhammer and can be easily executed by software, which is a serious problem in computer system security. RAMBleed is a side channel attack that reads information that cannot be accessed directly by observing bit flips caused by Rowhammer. The issue of RAMBleed is the time it takes to attack.<br> In this paper, in order to reduce the attack time, we review the conventional RAMBleed attack procedure and propose a RAMBleed attack that uses bit positions with high bit flip probability. We implemented the proposed method and conventional RAMBleed, and compared them. As a result, we show that the proposed method can reduce the attack time by about 60% while maintaining the recovery accuracy of conventional RAMBleed.","subitem_description_type":"Other"}]},"item_18_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"415","bibliographic_titles":[{"bibliographic_title":"コンピュータセキュリティシンポジウム2020論文集"}],"bibliographicPageStart":"410","bibliographicIssueDates":{"bibliographicIssueDate":"2020-10-19","bibliographicIssueDateType":"Issued"}}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"created":"2025-01-19T01:09:52.551590+00:00","id":208485,"links":{}}
