Abstract: This paper researches on electronic authentication in cloud computing and analyzes the deficiencies of mainstream authentication methods. We propose a more accurate and secure authentication solution using behavior and active privileges recognition technology. This solution can implement behavior-based active privileges recognition and choose adaptively whether to use high-strength safety certification. It also prevents hacking effectively and reduces the threats on security Certification.

Key words: cloud computing, electronic authentication, large data, privileges recognition, access control

摘要： 针对云计算环境下的身份认证方法进行研究，分析了主流认证方式存在的不足.结合行为与主动权限识别技术，提出更为准确、安全身份认证方案.该方案可以实现基于行为的主动权限识别，自适应选择是否采用高强度安全认证，有效地防止黑客入侵，降低认证环节的安全威胁.
