We compare possible solutions and propose an illegal copy detection framework for CAD tools based on watermarks embedded in VHDL codes. Then, we propose an illegal copy detection framework for CAD tools based on watermarks embedded in output VHDL codes. First, we study identification information to be embedded as a watermark. Next, we investigate a transformation mechanism for identification information using a cryptographic technique. We can prevent leaks of confidential information and alterations/removals of watermarks, and can detect alterations to VHDL codes by transforming the identification information to be watermarked. Finally, we propose watermark embedding mechanisms for VHDL codes. These embedding mechanisms involve a tradeoff between security and execution efficiency; thus, they should be selected giving due consideration to system requirements. Our framework can be applied to the protection of any software that outputs watermarkable data such as compilers/assemblers, software obfuscation tools, and multimedia authoring tools.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"310","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告コンピュータセキュリティ（CSEC）"}],"bibliographicPageStart":"303","bibliographicIssueDates":{"bibliographicIssueDate":"2008-07-17","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"71(2008-CSEC-042)","bibliographicVolumeNumber":"2008"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"created":"2025-01-18T23:10:31.081956+00:00","id":44310,"links":{}}
