Design And Implementation Of A Secure Android App Store

In recent years, the smart mobile phone is becoming more and more popular,android operating system has gradually become the largest market share in the mobile device application platform, which brings great convenience to people’s daily life. On this basis, android operating system is facing all kinds of mobile terminal security threats. In order to guarantee the information security of ordinary users, all kinds of security software already exists on the android platform, provide safety messages,email, and calling. But the software in the market have no specialty in preventing tampering for now, The purpose of this thesis is to enhance the security of the android operating system overall.This paper firstly introduces the basic concept of the android application market, the technology and method of current situation and development trend of research at home and abroad to use the existing stores. Secondly, introduces the concept of the android operating system architecture and the Dalvik virtual machine, security mechanism on the android operating system is studied. After revealing the security risks android system, relates to the security risks of several attack methods for android, this paper introduces the concept of digital signature algorithm and application.Secondly, the design of the Android application store network server is given in the text, the realization of access control, software management, storage and query, design management, log audit, database design and other functions.Android application store to give the design of the application store suite, to achieve the interface design, download module design and system function module design and other functions.Finally, according to the corresponding test environment is given a more perfect testing methods and methods to complete the functional and security testing of Android application store.
