摘　　要：由于病毒和黑客日益猖獗,泄密事件逐渐增多,因此设计并实现了一款基于单纤单向多模光纤的网络信息安全单向传输系统。对该单向传输系统进行了基于BLP模型的安全性分析,并对该系统进行改进,实现从低密级网络获取信息又能防止高密级网络信息泄露,提高了网络之间信息交换的安全性。Because the virus and the hacker are day by day rampant,the divulging a secret event increases gradually,therefore designed and has realized one section based on the single filament unidirectional multi-mold optical fiber＇s network information security unidirectional transmission system.This article has carried on to this unidirectional transmission system based on the BLP model safety analysis,and makes improvement to this system,realizes prevention for the high level of secrecy network information revelation from the low level of secrecy network,enhances the security level of information exchange in network.
