身份认证是云计算安全应用的挑战之一。针对Hadoop医学影像数据平台，提出改进的双服务器模型，并采用基于三角形原则的密码存储方法存储口令。其次，在该模型的基础上提出基于可信第三方的云存储架构。安全分析表明：基于双服务器模型的身份认证机制能够一定程度上改善口令认证的不足，加强口令存储安全，基于可信第三方的云存储架构能够实现用户信息管理和数据存储的分离，保护用户隐私。两者有机结合加强了医学影像平台的身份认证安全，防止攻击者访问云平台，窃取Dicom数据用于非法途径。

For Medical lmaging Platform based on Hadoop,this paper puts forward the modified two-server model and the pass-word storage method based on the fundamental properties of a triangle.Secondly,it proposes cloud storage architectures based on trusted third-party. Security analysis shows that the identity authentication mechanism based on modified two-server model overcome some drawback of the password authentication and the security of password storage.The cloud storage architectures based on trusted third-party isolates the personal information management and the data storage, which contributes to protecting the private information of users.This paper suggests the ldentity authentication mechanism, which strengthens the security of Medical lmaging Platform and prevents attackers steal Dicom data for il egal y.
