Protection against Code Obfuscation Attacks Based on Control Dependencies in Android Systems

摘要: In Android systems, an attacker can obfuscate application code to leak sensitive information. TaintDroid is information flow tracking system that protects private data in smartphones. But, TainDroid cannot detect control flows. Thus, it be circumvented by obfuscated attack based on dependencies. this paper, we present a collection of attacks system. We propose technical solution hybrid approach combines static and dynamic analysis. formally specify our two propagation rules. Finally, evaluate show avoid the dependencies using these
