Networked Test System and Its Security Design

摘要

The networked test system can be constructed using virtual instrument technology and Internet technology. It realizes resource share, remote data acquisition, and remote instrument operation, so it improves measurement automaticity and testing efficiency, as well as decreases testing cost. While at the same time, it brings some hidden security trouble of data communication. But security problem is often neglected by designer. Therefore this paper focuses on security design of testing system aiming at the feature of networked test system, presents that the system can adopt multiple security methods, such as user authentication, data encryption, digital signature, firewall, database backup and log management, and then presents implementation method in detail, so security and reliability of testing network can be effectively ensured.
