【摘要】 根据边防部队战斗文件管理信息系统的实际需求,在深入探究BLP模型(Bell-LaPadula model)安全性的基础上,充分利用其优点,设计一种在该系统中的应用模型。采用BLP模型的强制访问控制(mandatory access control)策略,确保信息不向下流动,适合于本系统中上级单位查看下级单位的收发文情况,同时保证下级不能查阅上级及友邻单位信息,从而保证系统的保密性、数据的可靠性及整个系统数据的安全。更多还原

【Abstract】 According to the actual demands of border troops fight document management information system,and a deep exploration of the security of BLP model(Bell-LaPadula Model),an application model for the system was deigned with extensively using BLP model’s advantages.BLP model’s mandatory access control strategy can ensure the information not flowing downward,,which perfectly suited to the demand that superior units in this system can view the information of subordinate units,while prevent lower levels from accessing to the information of higher levels and neighbor levels.It thereby ensures the confidentiality of the system,the reliability of the data and the security of the entire system data.更多还原
