頑強性を有する暗号の秘密分散法への応用 Some applications of non-malleable cryptography to secret sharing scheme 江村, 恵太 9779 野村, 明人 9780 00313700 Multi-secret sharing scheme (multi-SSS) is the method of distributing arbitrary numbers of secret information. Moreover, as a way anyone can check that secret information has been distributed correctly, M.Stadler defined publicly verifiable secret sharing scheme (PVSS). However the security of the method of Stadler is computationally. In this paper, we proposed that multi-SSS and PVSS using unconditionally secure asymmetric encryption (USAE) which is non-malleable cryptography. By using two methods together, it is possible to check that secret information has been correctly distributed to two or more secret information, without needing computational assumption. 金沢大学大学院自然科学研究科機能開発システム journal article 日本応用数理学会 2006-03-25 VoR application/pdf 日本応用数理学会論文誌 1045 16 15 25 AN10289996 0917-2270 https://kanazawa-u.repo.nii.ac.jp/record/7404/files/TE-PR-NOMURA-A-15.pdf http://hdl.handle.net/2297/7659 https://kanazawa-u.repo.nii.ac.jp/records/7404 jpn http://ci.nii.ac.jp/naid/110004706610/ 本文データは、日本応用数理学会の許諾に基づきCiNiiから複製したものである
