MoPS:一种模块化的长期存储保护方案

MoPS: A Modular Protection Scheme for Long-Term Storage

Christian Weinert, Denise Demirel, Martín Vigil, Matthias Geihs, Johannes Buchmann

摘要:

当前的技术趋势,例如云计算,允许将数据的存储、备份和归档外包。这提供了效率和灵活性,但也为数据安全带来了新的风险。特别是,开发保护方案以确保长期安全性变得至关重要,即超越密钥,证书和密码原语的生命周期。然而,所有当前的解决方案都不能为不同的应用场景提供最佳性能。因此,在这项工作中,我们提出了MoPS,一个模块化的保护方案,以确保长期存储的数据的真实性和完整性。MoPS对存储体系结构没有任何要求,因此可以与现有的归档或存储系统一起使用。它支持一组技术,这些技术可以插入、组合和迁移,以创建定制的解决方案,从而以最佳方式满足不同应用程序场景的要求。作为概念验证,我们实现了MoPS并提供了性能测量。此外,我们的实现提供了额外的功能,如非专家用户的指导和外部验证者的导出功能。

英文摘要:

Current trends in technology, such as cloud computing, allow outsourcing the storage, backup, and archiving of data. This provides efficiency and flexibility, but also poses new risks for data security. It in particular became crucial to develop protection schemes that ensure security even in the long-term, i.e. beyond the lifetime of keys, certificates, and cryptographic primitives. However, all current solutions fail to provide optimal performance for different application scenarios. Thus, in this work, we present MoPS, a modular protection scheme to ensure authenticity and integrity for data stored over long periods of time. MoPS does not come with any requirements regarding the storage architecture and can therefore be used together with existing archiving or storage systems. It supports a set of techniques which can be plugged together, combined, and migrated in order to create customized solutions that fulfill the requirements of different application scenarios in the best possible way. As a proof of concept we implemented MoPS and provide performance measurements. Furthermore, our implementation provides additional features, such as guidance for non-expert users and export functionalities for external verifiers.
