However, enough evaluation is not conducted for those methods and tools. This paper focuses on the existing obfuscation tools for the JVM platform and evaluates tolerance against de-obfuscation. Generally, we must identify the applied tools/methods at the first step for de-obfuscation. Therefore, this paper tries to identify applied obfuscation tools. The proposed method extracts the frequencies of opcode k-grams from many obfuscated software, and store them. Then, we try to identify the method by matching the opcode k-grams from the given software protected by some tool. From our experimental evaluation, the proposed method succeeded to identify Allatori; however, could not identify ProGuard and yGuard because ProGuard and yGuard change only little opcode sequences.","subitem_description_type":"Other"}]},"item_18_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"124","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":"119","bibliographicIssueDates":{"bibliographicIssueDate":"2019-10-14","bibliographicIssueDateType":"Issued"},"bibliographicVolumeNumber":"2019"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":201310,"updated":"2025-01-19T21:06:00.316196+00:00","links":{},"created":"2025-01-19T01:04:35.117791+00:00"}
