Recently, generating an unpredictable random number with high performance is a great challenge and widely sought. In particular, physical sources are capable to produce a random sequence that is very close to true random numbers. In this paper, we generate a random sequence using a physical resource such noise that is produced from a microphone input. In this study, a least significant bit of noise's data which is obtained from the microphone input is considered to be resources whose entropy rate is unknown, and then we use a randomness extractor which is developed by [1].","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"4","bibliographic_titles":[{"bibliographic_title":"研究報告コンピュータセキュリティ（CSEC）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2013-07-11","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"46","bibliographicVolumeNumber":"2013-CSEC-62"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2025-01-18T23:41:46.112589+00:00","id":94461,"links":{}}
