基于大数据的云计算安全系统设计及系统测试分析

Design and Test Analysis of Cloud Computing Security System Based on Big Data

在大数据时代,如何保障用户数据的隐私与安全,成为社会各界关注的焦点问题。对于云服务提供商来说,当用户将自己拥有的核心数据上传至云平台后,就必须要采取技术手段使用户数据免遭泄露。基于此,设计了一种云计算安全系统,该系统由身份认证模块、访问控制模块、数据加密模块、数据完整性验证模块四部分组成,可基于AS服务器进行用户身份认证,从源头上杜绝非法访问。在数据存储和传输过程中,则使用了AES算法对数据进行加密,避免了数据在传输和保存期间被第三方窃取、破坏。此外还可以借助于数据完整性验证模块,定期对数据进行备份,保证数据的完整与安全。从系统测试情况来看,该系统的身份认证、访问控制、数据加密等功能均可正常实现,有广阔的应用前景。

In the era of big data, how to protect the privacy and security of user data has become the focus of attention from all walks of life. For cloud service providers, when users upload their core data to the cloud platform, they must take technical measures to prevent user data from being leaked. Based on this, this paper designs a cloud computing security system, which consists of four parts: identity authentication module,access control module, data encryption module, and data integrity verification module. It can be used for user identity authentication based on AS server to prevent illegal access from the source. During data storage and transmission, the AES algorithm is used to encrypt data, preventing data from being stolen or damaged by a third party. In addition, the data integrity verification module can be used to periodically back up the data to ensure the integrity and security of the data. According to the system test, the functions of the system such as identity authentication, access control and data encryption can be realized normally, and it has a broad application prospect.
