基于属性加密算法的计算机数据安全访问控制技术OA

Aiming at the security risks of computer data file access and transmission in cloud computing environment,this paper proposes a computer data security access control technology scheme based on attribute encryption algorithm.It assumes that the communication channel is reliable,the third-party audit institution is trustworthy and the cloud computing data center is reliable.On the basis of the existing cloud computing data storage security architecture,the AES symmetric encryption algorithm is used to encrypt the data files in CDC to achieve USER security access,which is more secure and reliable than the traditional access control technology.This paper mainly analyzes the participation structure,main definition,program content and the implementation process of important programs of the above technical solutions,and explores the feasibility and optimization path of the application of the technology through simulation experiments to simulate the operating environment,in order to provide reference for computer data security access control.
