数据分片在电子政务中的应用方案

在信息技术的飞速发展的今天,电子政务日益受到各国政府的重视，相关技术也得到了迅速发展。访问控制是网络安全问题的重点之一,也是电子政务研究的重点问题。在现有的多种方法中，基于角色的数据访问控制方法应用的最广泛。文中指出了基于角色的访问控制方法的局限性，简单介绍了基于角色的数据访问控制模型、数据分片技术的类型和原则。在此基础上提出了将数据分片技术与角色权限控制相结合的访问控制思想，并应用于电子办事处系统中。

Application Scheme of Data Spliting Technique in E-Government

Today E-government is being set store by governments increasingly. The technology have developed promptly in the same time. Access control is one of safety problems in network, and is the keystone in investigation of E-government. RBAC(role-based access control) is the most abroad plan in manifold plans. This paper introduced model of RBAC and fundamental of data spliting technique. Based on it, this paper brought forward a new idea of access control that combined data spliting technique with RBAC, and used it in system of E-office.
