面向企业内容应用的端对端加密解决方案

An End-to-End Encryption Solution for Enterprise Content Applications

Chaoting Xuan

摘要:

企业客户使用的内容托管服务(如Dropbox,OneDrive和Google Drive)部署在内部或云中。由于用户可能会将业务敏感数据(内容)存储在这些托管服务中,因此他们可能希望保护自己的数据不泄露给任何人,甚至是IT管理员。不幸的是,即使内容(文件)在托管服务中被加密,它们有时仍然可以被IT管理员访问。如果IT管理员变得恶意(如不满的员工)或他的帐户被黑客入侵,敏感数据可能会暴露给公众。我们提出了一种端对端加密(E2EE)解决方案来解决这一挑战。用户数据在客户端侧(移动终端)加密,并且在传输中和在服务器上静止时保持加密。具体来说,我们设计了一种新的方法,允许主秘密恢复和托管,同时保护他们免受恶意管理员的访问。此外,我们提出了一个内容(文件)加密方案,实现隐私和粒度访问控制。它还可以与当今企业用户使用的主要内容主机服务无缝集成。

英文摘要:

The content host services (like Dropbox, OneDrive, and Google Drive) used by enterprise customers are deployed either on premise or in cloud. Because users may store business-sensitive data (contents) in these hosting services, they may want to protect their data from disclosure to anyone else, even IT administrators. Unfortunately, even contents (files) are encrypted in the hosting services, they sometimes are still accessible to IT administrators today. The sensitive data could be exposed to public if the IT administrator turns malicious (like disgruntled employee) or his account is compromised by hackers. We propose an end-to-end encryption (E2EE) solution to address this challenge. The user data is encrypted at client side (mobile device) and remains encrypted in transit and at rest on server. Specifically, we design a new method to allow master secret recover and escrow, while protecting them from being accessed by malicious administrators. In addition, we present a content (file) encryption scheme that achieves privacy, and granular access control. And it can be seamlessly integrated with major content host services used by business users today.
