    Security Analysis and Enhancement of Third-Party Android Push Service

    • Push service is becoming a basic service for smartphone applications. Many companies, including official and third parties, have released their push services. In order to reduce resource cost, some third-party push services share push channels among applications running on the same device and using the same push service, which means that the background push component of one application acts as the push data distribution center for other applications. Due to the lack of considering security attributes such as confidentiality and integrity, the distribution part faces a variety of attacks. In this work we analyze the security issues in the data distribution part of third-party push services on Android. We design a corresponding attack model and implement attacks including eavesdropping, data tampering, forgery and replay attacks. During our experiments, it shows that most of the third-party Android push services using shared channels are subject to these attacks. It may cause some security hazards such as user privacy leakage and phishing attack. To mitigate the above threats, we propose SecPush which is a security enhancement scheme for Android push service. SecPush secures data distribution by introducing encryption and HMAC algorithm. Experimental results show that SecPush can effectively protect push data against eavesdropping, data tampering, forgery and replay attacks.
