Spatial data security control system based on access mode protection

Abstract

The invention discloses a spatial data security control system based on access mode protection. The spatial data security control system comprises an authorization server, a service provider, a service requester, a radio-frequency identification (RFID) reader and an RFID tag; an authorization server module provided by the invention comprises three parts including a key library, an attributive library and a strategy library; an authorized public key of the service requester and an encrypted private key of the service provider are stored in the key library; attribute information of all parties of the system is stored in the attributive library; a decision strategy of the system is stored in the strategy library; the key library, the attributive library and the strategy library each have the basic functions of increasing, deleting, searching and backing up stored information and the like; requirements on an information source in an access control process are effectively satisfied; a strategy is implied in the encrypted secrete key in the encryption processing operation of the service provider; an access control rule to resource setting is contained; and simultaneously, the data security is also effectively protected.

Description

technical field [0001] The invention belongs to the technical field of electronic information security control systems, in particular to a space data security control system based on access mode protection. Background technique [0002] With the rapid development and popularization of computer technology and network technology, multiple geographically dispersed organizations have realized remote dynamic interaction and collaborative work through computer networks, and network-based e-commerce, e-government, network scientific research and other activities have gradually become mainstream. application mode. The network-based cross-domain multi-organization large-scale information system application has the characteristics of openness, distribution, and dynamics, so cross-domain access control presents the characteristics of resource distribution, activity dynamics, and subject ignorance. . How to effectively control the resources of the service provider and protect the priv...
