Privilege mechanism is the core of Android security mechanism. On the basis of analysis on principle of privilege escalation

a scheme of privilege escalation attack detection is presented. The scheme makes full use of characteristics of permission transfer and communication connection between components

realize from dynamic and static states

detection rate based on defect is 78. 7 %

and based on component is more than 50 %. Experimental results show that the detection method can effectively detect privilege escalation attack

which provides a feasible solution for solving problems of reliability of privilege escalation attack detection model.
