The world produces more digital data annually that’s growing exponentially. Storing data for decades is challenging and securing it for so long is even more challenging. This project develops secure, efficient, long-term archival storage systems for digital information that endures beyond a single human lifetime. The project uses a long-term security model that is safe against faster computers and even quantum computers and can protect against malicious "insiders" who abuse their access to secretly steal data slowly over years. Lastly, the project explores how to maintain long-term data securely and efficiently, even if individual storage providers cease to exist.This project develops techniques to store archival data securely and reliably for a long-time using information theoretic security and combinatorial security. The project explores techniques to allow data to survive errors ranging from corruptions of a few bytes to large-scale cloud failures. It then explores the trade-off between additional storage requirements, data security and reliability, and system performance. Empirical evaluation of a prototype system provides insights into real-world issues in implementing these techniques over the project’s lifespan, and a simulator embodying these techniques allows projection of the techniques’ effectiveness over much longer time frames.This project fosters collaborations across systems, theory, and security researchers to develop practical techniques to both secure data for many years and ensure that the data endures unchanged. Storage must meet both criteria for a society based on digital data to rely on it. All source code for a prototype system and simulator is maintained and released publicly. Material from this project is integrated into graduate level courses and a new “Secure Storage Systems” course. The project recruits and co-advises several under/graduate students, with a focus on female and Hispanic students, both traditionally underrepresented in computer systems research.The project's artifacts—software, source code, data sets, secure archive simulator, traces, and results—are all embodied in a system called "SecArch: Secure Archives". Results will be disseminated using peer-reviewed publications and arxiv.org. All artifacts will be made public through the project Website: https://www.filesystems.org/secarch. The project plans to maintain the site for at least ten years following the end of the project.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

世界每年生产更多的数字数据，呈指数增长。数十年来存储数据是挑战，并且将其确保很长时间是更大的挑战。该项目为数字信息开发了安全，高效，长期的档案存储系统，这些信息可以忍受超出人类生命周期的数字信息。该项目使用了一个长期安全模型，该模型可以安全地防止更快的计算机甚至量子计算机，并且可以预防恶意的“内部人士”，这些恶意“内部人士”滥用了他们在多年来缓慢偷偷窃取数据的机会。最后，即使单个存储提供商不再存在，该项目也探讨了如何安全有效地维护长期数据。该项目开发了使用信息理论安全性和组合安全性的技术，可以将档案数据牢固地存储为可靠地存储档案数据。该项目探讨了技术，以允许数据生存，从校正几个字节到大规模云故障。然后，它探讨了其他存储要求，数据安全性和可靠性以及系统性能之间的权衡。对原型系统的经验评估为实施这些技术实施这些技术的实施这些技术提供了对现实世界问题的见解，并且一个体现这些技术的模拟器可以预测该技术在更长的时间范围内的有效性。该项目的项目促进了该系统的合作，并在系统，理论和安全研究人员的过程中确保了许多确保数据的确保数据，并且可以确保数据的确保数据，并且可以确保该数据的确保数据，并且该数据持续了多年的数据。存储必须符合基于数字数据的社会的两个标准才能依靠它。所有原型系统和模拟器的源代码均已公开维护和发布。该项目的材料已集成到研究生级课程中，并进行了新的“安全存储系统”课程。该项目报告并共同审议了几位不足/研究生，关注女性和西班牙裔学生，传统上都在计算机系统研究中代表不足。结果将使用同行评审的出版物和arxiv.org传播。所有工件将通过项目网站公开：https：//www.filesystems.org/secarch。该项目计划在项目结束后至少维护该站点至少十年。该奖项反映了NSF的法定任务，并通过使用基金会的知识分子优点和更广泛的影响评估标准来评估，被认为是珍贵的支持。
