A Conspire-accesses Risk Control Model Based on Information Flow Graph
Chao Wang, Pla Information · Jisuanji gongcheng · 2013
To solve the problem of nonlicet indirectly access in the information system,this paper proposes a conspire-accesses risk control model based on information flow graph.It forms an information flow graph through recording history accesses,and defines the conspire-accesses.It defines the access control model based on states machine,to prevent the conspire-accesses by security theorems and rules,and proves the security of the rules.It analyses and verifies the model’s validity based on information entropy theory,and the result proves that the model can prevent conspire-accesses.
