摘要
现有数据访问控制技术的授权机制数据处理能力较差,导致决策时间过长,为此设计一种新的舰船电子信息系统数据访问控制技术。获取中间件属性特征构建信息评价矩阵,量化处理系统访问对象,建立系统访问授权机制,识别用户属性,显示授权结果,设置数据访问控制功能,验证用户身份信息,保证访问权限有效性。实验结果表明:在不同的访问请求条件下,此次设计的舰船电子信息系统数据访问控制技术,其决策时间比其他2种现有方法的决策时间,分别少18.47 ms和18.86 ms,证明此次设计的舰船电子信息系统数据访问控制技术性能更佳。
The authorization mechanism of the existing data access control technology has poor data processing capabilities, resulting in too long decision-making time. For this purpose, a new ship electronic information system data access control technology is designed. Obtain middleware attributes to construct an information evaluation matrix, quantitatively process system access objects, establish system access authorization mechanisms, identify user attributes, display authorization results, set data access control functions, verify user identity information, and ensure the validity of access permissions.Experimental results: Under different access request conditions, the decision-making time of the ship electronic information system data access control technology designed this time is 18.47 ms and 18.86 ms less than the decision-making time of the other two existing methods, which proves this time. The designed ship electronic information system data access control technology has better performance.
