云内容的安全框架及其关键技术

文章从云内容面临的安全挑战出发,针对云内容面临的安全问题,提出云内容的安全模型。模型包括云内容管理安全、云内容访问安全、云内容的健康性安全3个层次。在此模型基础上,文章探讨了云内容的安全框架及关键技术,包括云内容隔离安全保障技术、云内容存储安全保障技术、数据加密存储技术、密钥管理技术、数据备份技术、数据销毁技术、密码认证技术、密钥认证技术、用户权限管理技术、筛子理论、加密协议识别技术、用户访问行为检测技术等。摘要:

Framework and Key Techniques for Securing Cloud Content

In this paper, we propose a model for securing cloud content. This model has three security levels： management security, access security, and condition of cloud content. We propose a security framework that includes isolated security, cloud storage security, encryption storage, private key management, disaster backup, data destruction, password and private key authentication, authority management, griddle method, encryption protocol identification, and access behavior detection.
