远程测试系统与测试数据的安全传输

Remote test system and security transmition of test data

远程测试系统将分布在各个节点的测试数据、测试设备通过计算机网络连接在一起,构成了一个集数据采集、传输、处理和应用的综合信息网络,实现了远程控制和操作测量仪器,获取和传递测试信息(或数据)。采用基于DES和RAS的混合加密算法及数字签名技术实现了该远程测试系统的安全可靠运行。应用于远程虚拟实验室中,对仪器使用者的身份进行数字签名认证后,获取仪器使用权限,可远程操作仪器,并将测试的数据加密后传输,保证了远程虚拟实验室的安全性。

The remote test system, which can connect distributed test data and test devices with computer network, forms a synthetical information network integrated with data acquisition, transmission, processing and application. Remote controlling and manipulating test devices, remote acquiring and transmitting test data can be realized. In order to assure the security operation of remote test system, mixed encryption technology based on DES and RSA as well as digital signature are used. In remote virtual lab, after checking the user identification with the digital signature and acquiring the operating authority, the user can remotely operate the virtual instruments and transmit the encrypted data, assuring the security of remote virtual lab.
