基于OAuth的开放授权技术及在云计算中的应用

摘要

在云计算中，传统应用系统中使用的基于单一安全域的身份认证和资源授权模式已无法适应复杂环境中的管理要求，需要制定跨域访问的安全控制策略.在重点分析了云计算中数据安全和隐私保护所遇到的挑战的基础上，有针对性地介绍了OAuth2.0协议的原理和功能特点，提出了开放授权技术在云计算中的应用优势，并通过一个工程应用实例讨论了具体的实现方法和思路.%Cloud computing is a complex network environment, and traditional applications use authorization and authentication based on a single security domain mode, it does not meet the requirements of cloud computing, cloud computing needs to establish cross-domain security access control policy. Based on the analysis of the challenges of data security and privacy protection in the cloud computing, this paper introduces the principle and function of the OAuth2.0 protocol, and points out the OAuth2.0 advantage of open license technology and its application in the cloud computing. Finally, through a cloud computing example, the implementation methods and development ideas had been discussed.
