云存储提供了一种更为简单的方式来私下和公开地共享文件。一个好的云存储提供商(SCP)不仅通过访问速度或可共享给他人的文件大小来衡量，而且还通过文件共享本身的安全问题来衡量。本文分析了百度、Weiyun和Kanbox这3家中国csp的文件共享安全性，成功暴露了这些csp自身的弱点，并提出了相应的对策建议，旨在使其在提高安全性的同时保持质量。

原文题目：Revealing the Weaknesses of File Sharing System on Cloud Storages

原文：Cloud storage provides the simpler way to share the files privately and publicly. A good Cloud Storage Provider (SCP) is not only measured by the access speed or file size that can be shared to others, but also regarding the security issues in file sharing itself. In this paper, we analyze the security of file sharing in 3 Chinese CSPs, which are: Baidu, Weiyun and Kanbox. Those CSPs have their own vulnerabilities that successfully revealed. We also provide some suggestions to countermeasure the weaknesses so that they can maintain the quality while improving the security.
