摘要: Android as a widest used operating system for smartphones and mobile devices uses permissions to restrict malicious applications (apps). However, malware developers use various social engineering methods entice users installing malwares after granting critical by users. Therefore, it is essential estimate security risks of untrusted apps help making better decisions regarding app selection installation. In this paper, the concept criticality precisely defined according abuse known their legal usage useful apps. Based on definition analyzing requested large numbers benign apps, new criterion proposed measure This benefits from concepts entropy information gain separating criterion, more informative have higher impacts computed risk values. order evaluate two datasets recent non-malicious been constructed analyzed against existing ones. analysis shows that permission patterns are changed over time. Empirical evaluations previous reveal superiority with respect previously ones in terms assigning larger values malwares.
