摘　　要：本文设计了大型企业应用系统远程加密访问系统,采用MPEG-2加解密系统实现远端的安全访问。由于远程加密的加扰器与CA系统分为两地,在加密系统进行传输时可能会出现运输故障、加扰设备工作故障、IP链路故障等问题,因此本文还设计了应用系统远程加密监测平台,确保远程加密访问系统在传输过程和远端用户接收信息的正常。最后利用CP-ABE算法对应用系统远程加密访问进行控制。实验结果表明,本文研究的系统性能较好,在用户数目为800时权限变更时间为3 s,并且远程加密的安全性较高,在进行80次实验中丢包率最高为1%。In the paper,a remote encryption access system is designed for large-scale enterprise application systems,and uses MPEG-2 encryption and decryption systems to achieve remote access.Because the remote encrypted scrambler and the CA system are divided into two places,transportation failures,scrambling equipment malfunctions,and IP link failures may occur when the encryption system is transmitting.Therefore,this article also designs application.The system remote encryption monitoring platform ensures that the remote encryption system is in the transmission process and the remote user receives the information normally,and finally uses the CP-ABE algorithm to control the remote encryption access to the application system.The experiment results show that the performance of the system studied in this paper is better.When the number of users is 800,the permission change time is 3 s,and the security of remote encryption is high.The packet loss rate is 1%in 80 experiments.
