Android access control system for enhancing confidentiality and integrality

Abstract

The invention belongs to the technical field of mobile communication equipment, and particularly relates to an Android access control system for enhancing confidentiality and integrality on the basis of cryptography and policy driven. In order to promote system confidentiality and integrality protection, the Android is improved, and the Android access control system based on existing safety mechanisms is realized. The improved Android access control system comprises a contact management module, a short message management module, an induction source control module, a strategy management module and a key management module. All the modules cooperate with one another, and finally safety of Android user data access and induction module access can be achieved. In addition, the improved Android access control system can be used for operation systems of Android users so that different protection settings on personal data and induction sources under different scenes can be achieved, and complexity of safe strategy management can be simplified beneficially.

Description

technical field The invention belongs to the technical field of mobile communication equipment, and in particular relates to an Android confidentiality integrity enhanced access control system based on cryptography and policy-driven. Background technique In recent years, the number of mobile Internet terminal devices, such as smart phones and tablet computers, is showing a sharp increase. Users store a large amount of private data on mobile smart devices, such as contacts, text messages, etc. Many domestic telecom operators, equipment manufacturers, Internet companies, etc. can carry out "secondary processing" based on the openness of the Android system, build their own application malls, and gather mobile Internet users. However, due to the lack of powerful program security review mechanisms and detection methods by the operators of various "app malls", a large number of programs aimed at obtaining user privacy information have sprung up, which may lead to a large number o...

And it adopts encryption outside the library, and encrypts and stores the entire database file as an ordinary file, which makes the reading and writing of the database more troublesome. Every time it is written and read, the entire data file must be encrypted and decrypted, resulting in program writing and database processing. The reading and writing speed will decrease
