Abstract
Due to the characteristics of the current open-source Android system, and looser user rights management mechanism, information security issues become a problem of common concern to the user. At the present stage, there are many measures encrypting data for Android database, which are divided into several aspects of hardware layer, core layer, virtual machine layer and application framework layer. This paper presents a method which achieves the database encryption by modifying SQLite source code in Libraries and Android Runtime Layer. The encryption function can not only encrypt the data itself, but also be invoked by the upper application though JNI interface, so that the application can access more secure database, and improve the security of the instant messaging application. Experimental results show feasibility and effectiveness of the SQLite database encryption which is used in the instant messaging application.
