摘要
电子机构为自治主体间可信业务协同分析提供了一种框架,但现有的电子机构模型对其中存在的各种信息流还缺乏有效地分析和规范.文中以分析角色之间信息流的传递为前提,提出了用来发现电子机构中潜在非法信息流的算法,并给出了解决非法信息流的控制策略.
Electronic institution provides a promising way towards modeling and developing dependable distributed collaboration system in an open and heterogeneous environment. However, there are few studies concerning information flow security in existing institutional models. Based on analyzing information flows among roles, the paper puts forward an algorithm for searching potential illegal information flows in an electronic institution. Also some control strategy of preventing illegal information flows is given.
