总结 协同云应用已经成为大数据时代的主导应用模式。这些应用程序通常会生成大量协作文件，这些文件与所有协作参与者共享其所有权。重复数据删除是一种很有前景的解决方案，可以提高存储效率并节省用户开支。然而，如何安全地证明共享文件的共享所有权并解决因使用重复数据删除而造成的攻击仍然是一个悬而未决的问题。为了解决上述问题，在本文中，我们引入了共享所有权证明（PoSW）的新概念，并构建了一种基于收敛加密、秘密共享和布隆过滤器的安全多服务器辅助PoSW（ms-PoSW）方案，用于保护共享文件的客户端重复数据删除。在ms-PoSW方案中，我们采用共享收敛密钥来避免单点故障，引入秘密共享算法来实现共享所有权，并在共享所有者和云服务器之间构造一种新颖的交互协议来证明共享所有权。此外，构建了混合 PoSW 方案来解决混合云架构的安全证明。最后，安全分析和性能评估表明了所提方案的安全性和效率。
Summary Collaborative cloud applications have become the dominant application mode in the big data era. These applications usually generate plenty of cooperative files, which share their ownerships with all collaborative participants. Data deduplication is a promising solution to improve the storage efficiency and save the user expenditure. However, it remains an open issue on how to securely prove the shared ownerships for the shared files and address the attacks on account of using data deduplication. To tackle the above issue, in this paper, we introduce a novel concept of the Proof of Shared oWnership (PoSW) and construct a secure multi-server-aided PoSW (ms-PoSW) scheme for securing client-side deduplication for the shared files, which is based on the convergent encryption, secret sharing, and bloom filter. In the ms-PoSW scheme, we employ a sharing convergent key to avoid the single point of failure, introduce the secret sharing algorithm to implement the shared ownership, and construct a novel interaction protocol between the shared owners and the cloud server to prove the shared ownership. Furthermore, a hybrid PoSW scheme is constructed to address the secure proof of hybrid cloud architectures. Finally, security analysis and performance evaluation show the security and efficiency of the proposed schemes.
