在信息社会的背景下，每天都有大量的信息被交换或发布。在各种信息发布案例中，医疗文件发布因其在提高医疗服务质量和疗效方面的潜力而备受关注。然而，在后续应用中，医疗文件的完整性和来源认证是优先考虑的问题。此外，当医疗文件不受控制地提供给不受信任的第三方时，许多此类信息的敏感性也会造成严重的隐私威胁。可重写签名允许任何一方删除经过身份验证的文档的片段，同时保证最终（发布）子文档的来源和完整性身份验证。然而，大多数现有的可重写签名方案（rss）都容易受到不诚实编校者或非法编校检测的攻击。为了解决上述问题，我们提出了两种不同的具有灵活释放控制的rss （rss - frc）。我们还分析了我们的结构在安全性，效率和功能方面的性能。分析结果表明，从安全性和效率两方面来看，我们的施工性能比其他施工具有明显的优势。
In the context of Information Societies, a tremendous amount of information is daily exchanged or released. Among various information-release cases, medical document release has gained significant attention for its potential in improving healthcare service quality and efficacy. However, integrity and origin authentication of released medical documents is the priority in subsequent applications. Moreover, sensitive nature of much of this information also gives rise to a serious privacy threat when medical documents are uncontrollably made available to untrusted third parties. Redactable signatures allow any party to delete pieces of an authenticated document while guaranteeing the origin and integrity authentication of the resulting (released) subdocument. Nevertheless, most of existing redactable signature schemes (RSSs) are vulnerable to dishonest redactors or illegal redaction detection. To address the above issues, we propose two distinct RSSs with flexible release control (RSSs-FRC). We also analyse the performance of our constructions in terms of security, efficiency and functionality. The analysis results show that the performance of our construction has significant advantages over others, from the aspects of security and efficiency.
