摘　　要：IEEE1394总线具有传输速度快,距离远、可靠性高等特点,在航空领域和工业领域有着广泛的应用。1394仿真卡可仿真模拟总线通信情况,为了便捷、高效地在实验室环境中使用仿真卡,针对仿真卡开发了一系列的软件。基于1394仿真卡提出一种授权管理方案,在Flash中划分授权管理扇区储存所需信息,根据仿真卡信息与计算机信息生成License并进行授权,在软件运行前将各类信息进行对比,信息均一致可正常使用,可以有效地保护仿真卡和应用软件的安全性。IEEE1394 bus has the characteristics of high transmission speed,long distance and high reliability,and is widely used in aviation and industrial fields.The 1394 simulation card can simulate the communication of the bus.In order to use the simulation card conveniently and efficiently in the laboratory environment,a series of software is developed for the simulation card.This paper proposes an authorization management scheme based on 1394 emulation card,which divides the authorization management sectors in Flash to store the required information,generates License according to the emulation card information and computer information and authorizes it,and compares all kinds of information before the software runs,and the information is consistent and can be used normally.It can effectively protect the security of the simulation card and application software.
