Pseudo-random numbers are generated by definite periodicity, so, their usefulness in cryptographic applications is somewhat limited. On the other hand, naturally-generated physical-random numbers have no calculable periodicity, thereby making them ideal for the task. Diode lasers\u0027 considerable wideband noise gives them tremendous capacity for generating physical-random numbers, at a high rate of speed. We measured a diode laser\u0027s output with a fast photo detector, and evaluated the binary-numbers from the diode laser\u0027s frequency noise characteristics. We then identified and evaluated the binary-number-line\u0027s statistical properties. We also investigate the possibility that much faster physical-random number parallel-generation is possible, using separate outputs of different optical-path length and character, which we refer to as \"coherence collapse\".", "subitem_description_type": "Abstract"}]}, "item_8_description_5": {"attribute_name": "内容記述", "attribute_value_mlt": [{"subitem_description": "Physics and simulation of optoelectronic devices 20 : 23-26 January 2012 : San Francisco, California, United States : Jan 2012, San Francisco, CA", "subitem_description_type": "Other"}]}, "item_8_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "International Society for Optical Engineering, SPIE"}]}, "item_8_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "info:doi/10.1117/12.908011", "subitem_relation_type_select": "DOI"}}]}, "item_8_rights_15": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "Copyright 2012 Society of Photo-Optical Instrumentation Engineers"}]}, "item_8_select_19": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_8_source_id_11": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AA10619755", "subitem_source_identifier_type": "NCID"}]}, "item_8_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "0277786X", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Takamori, Hiroki"}], "nameIdentifiers": [{"nameIdentifier": "169355", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Doi, Kohei"}], "nameIdentifiers": [{"nameIdentifier": "169356", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Maehara, Shinya"}], "nameIdentifiers": [{"nameIdentifier": "169357", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Kawakami, Kohei"}], "nameIdentifiers": [{"nameIdentifier": "169358", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Sato, Takashi"}], "nameIdentifiers": [{"nameIdentifier": "169359", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Ohkawa, Masashi"}], "nameIdentifiers": [{"nameIdentifier": "169360", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Ohdaira, Yasuo"}], "nameIdentifiers": [{"nameIdentifier": "169361", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Sakamoto, Shuichi"}], "nameIdentifiers": [{"nameIdentifier": "169362", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2019-08-26"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "8255_825521.pdf", "filesize": [{"value": "2.0 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 2000000.0, "url": {"label": "8255_825521.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/31024/files/8255_825521.pdf"}, "version_id": "e4d8bbbb-3783-4d15-898a-5bfb04e09f66"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "laser diode", "subitem_subject_scheme": "Other"}, {"subitem_subject": "physical-random number", "subitem_subject_scheme": "Other"}, {"subitem_subject": "rapid generation", "subitem_subject_scheme": "Other"}, {"subitem_subject": "frequency noise", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "資源タイプ", "attribute_value_mlt": [{"resourcetype": "conference paper", "resourceuri": "http://purl.org/coar/resource_type/c_5794"}]}, "item_title": "Fast random-number generation using a diode laser\u0027s frequency noise characteristic", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Fast random-number generation using a diode laser\u0027s frequency noise characteristic"}, {"subitem_title": "Fast random-number generation using a diode laser\u0027s frequency noise characteristic", "subitem_title_language": "en"}]}, "item_type_id": "8", "owner": "1", "path": ["457", "1827"], "permalink_uri": "http://hdl.handle.net/10191/31050", "pubdate": {"attribute_name": "公開日", "attribute_value": "2014-12-12"}, "publish_date": "2014-12-12", "publish_status": "0", "recid": "31024", "relation": {}, "relation_version_is_last": true, "title": ["Fast random-number generation using a diode laser\u0027s frequency noise characteristic"], "weko_shared_id": null}
