云存储的安全性技术分析

信息时代技术飞速发展，人类需要更强大的信息处理能力，云计算技术应运而生同时迅速流行，与之相辅相威的云存储也得到了广泛的关注和支持。但云存储自身的数据安全问题阻碍其推广应用，成为制约云存储发展的首要问题。云存储的安全问题也不仅仅是传统安全能够完全解决的，这其中涉及到一些新的关键技术和管理技术。本文介绍了云存储的相关概念及优势所在，揭示了其脆弱的安全性，并对云存储安全中的数据加密存储与检索、密文访问控制等关键技术进行了分析，最后提出了一些提高安全性的措施。

Analysis of the Security of Cloud Storage Technology

With the rapid development of information age technology, the world needs a more powerful information processing capabilities of cloud computing technology came into being at the same time growing in popularity. Cloud storage has also been widespread concern and support, but the cloud storage data security issues that hinder its promotion and application, this problem has become the primary problem restricting the development of cloud storage. Cloud storage security issues not just the traditional security can completely solved, which involves a number of new key technologies and management techniques. This paper introduces the concept and advantages of cloud storage which reveals its fragile security, and analyzed the encrypted data storage and retrieval,the ciphertext access control and other key technologies in the cloud storage security. Finally. some measures has been designed to improve the security of cloud storage.
