C/S模式下应用C及VBScript语言实现WinCC组态加密

Realizing WinCC Configuration Encryption Using C and VBScript in C/S Model

综合运用ANSI-C和VBScript语言编制加密程序,实现了执行动作的授权化、组态环境和运行环境的分离以及运行环境的安全退出等功能。设置W inCC组态参数,实现了工程脚本的加密、W indows热键的屏蔽以及运行窗口关闭等常规按钮的消隐。

According to the application of WinCC, the principle and method of project software encryption in C/S model are presented. The encryption procedure is compiled using VBScript and ANSI-C language, which accomplishes the authorization of operation, separation of configuration and operation environment, and safe withdrawal function. The configuration parameters are established to realize script encryption, shielding of Windows hotkeys and hide of conventional buttons such as close windows. The safety of software is enhanced and the running of production is guaranteed.
