Nevertheless, privacy has been the primary concern of reporters. In this paper, we propose a privacy-preserving confidential reporting system with designated reporters (PPCRS-DR) to protect the privacy of reporters and the confidentiality of reports. Our PPCRS-DR provides the following interesting features: (1) for an event, an auditor can designate a reporter to report; (2) an auditor can neither see the report nor know the reporter\u2019s identity from an encrypted report if the reporter is not the designated one; (3) when an auditor is unavailable, he\/she can temporarily designate a delegatee to collect and review reports on behalf of him\/her. We formalize both the definition and security model of our PPCRS-DR, and propose a concrete construction. Furthermore, the security of the proposed PPCRS-DR is formally proven. The implementation shows that it is efficient. The novelty is to implement flexible decryption delegation of CRSs and protect reporters\u2019 privacy.<\/jats:p>","DOI":"10.1093\/comjnl\/bxad114","type":"journal-article","created":{"date-parts":[[2023,12,2]],"date-time":"2023-12-02T11:18:58Z","timestamp":1701515938000},"page":"1951-1962","source":"Crossref","is-referenced-by-count":0,"title":["Privacy-Preserving Confidential Reporting System With Designated Reporters"],"prefix":"10.1093","volume":"67","author":[{"given":"Jinguang","family":"Han","sequence":"first","affiliation":[{"name":"School of Cyber Science and Engineering, Southeast University , Nanjing, Jiangsu 210096 , China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Willy","family":"Susilo","sequence":"additional","affiliation":[{"name":"School of Computing & Information Technology, University of Wollongong , Wollongong, New South Wales, NSW 2522 , Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Liquan","family":"Chen","sequence":"additional","affiliation":[{"name":"School of Cyber Science and Engineering, Southeast University , Nanjing, Jiangsu 210096 , China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jianchang","family":"Lai","sequence":"additional","affiliation":[{"name":"School of Cyber Science and Engineering, Southeast University , Nanjing, Jiangsu 210096 , China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ge","family":"Wu","sequence":"additional","affiliation":[{"name":"School of Cyber Science and Engineering, Southeast University , Nanjing, Jiangsu 210096 , China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2023,12,1]]},"reference":[{"key":"2024062312372616200_ref1","article-title":"Aviation safety reporting system","author":"The National Aeronautics and Space Administration (NASA)","year":"2020"},{"key":"2024062312372616200_ref2","article-title":"Confidential human factors incident reporting programme","author":"The CHIRP Charitable Trust","year":"2021"},{"key":"2024062312372616200_ref3","article-title":"Confidential reporting on structural safety","author":"The Standing Committee on Structural Safety (SCSS)","year":"2008"},{"key":"2024062312372616200_ref4","article-title":"The Confidential Reporting System for Surgery: CORESS","volume-title":"The Annals of The Royal College of Surgeons of England","author":"","year":"2023"},{"key":"2024062312372616200_ref5","first-page":"189","article-title":"Confidential reporting on structural safety","volume":"164","author":"Soane","year":"2011","journal-title":"Forensic Eng."},{"key":"2024062312372616200_ref6","article-title":"Confidential reporting on structural safety \u2013 united states","author":"Structural Engineering Institute (SEI)","year":"2020"},{"key":"2024062312372616200_ref7","article-title":"Confidential incident reporting and analysis system","author":"CIRAS","year":"2021"},{"key":"2024062312372616200_ref8","doi-asserted-by":"crossref","first-page":"249","DOI":"10.1308\/rcsann.2006.88.3.249","article-title":"CORESS \u2013 a confidential reporting system for surgery","volume":"88","author":"Lewis","year":"2006","journal-title":"Ann.
