本稿では,Ethereumスマートコントラクトを対象に先述した複雑な動作を解析するシンボリック実行ツールRA を提案する.RA はコントラクトの生成や外部呼び出しが起きた状況であっても,プログラムの動作を制御フローグラフを通じて正確に表現できる.これにより,既存ツールに比べコード網羅率を大幅に上昇させるとともに,複雑化している攻撃手法に対する脆弱性を検査することが期待できる.","subitem_description_type":"Other"}]},"item_18_description_8":{"attribute_name":"論文抄録(英)","attribute_value_mlt":[{"subitem_description":"Smart contracts are programs that run on blockchains and are used to develop decentralized applications. While attacks against smart contracts involving complex operations such as contract creation and calling external contract have been reported, existing inspection tools only focus on operations within a single contract and thus cannot analyze such attacks.
In this paper, we introduce a new symbolic execution tool, named RA, to analyze Ethereum smart contracts including the complex operations described above. RA is able to express a program behavior even against attacks based on the complex operations through generating a control flow graph. Consequently, as well as improving a code coverage in comparison with the existing tools, RA can be potentially used to analyze inspecting attacks based on vulnerabilities to complicated attack methods.","subitem_description_type":"Other"}]},"item_18_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"576","bibliographic_titles":[{"bibliographic_title":"コンピュータセキュリティシンポジウム2019論文集"}],"bibliographicPageStart":"569","bibliographicIssueDates":{"bibliographicIssueDate":"2019-10-14","bibliographicIssueDateType":"Issued"},"bibliographicVolumeNumber":"2019"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"created":"2025-01-19T01:04:38.771310+00:00","updated":"2025-01-19T21:04:02.812460+00:00"}
