Problems solved by technology

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

Abstract

The invention belongs to the technical field of mobile communication equipment, in particular to an Android confidentiality integrity enhanced access control system based on cryptography and policy-driven. The invention improves the Android system to enhance the system confidentiality integrity protection target, and realizes the Android system enhanced access control system based on the existing security mechanism. The improved Android access control system includes a contact management module, a short message management module, a perception source control module, a policy management module, and a key management module. Each module cooperates with each other to finally realize the security of Android user data access and perception module access . In addition, the present invention can be used in the operating system of Android users to implement different protection settings for personal data and perception sources in different scenarios, which helps to simplify the complexity of security policy management.

Description

technical field [0001] 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 [0002] 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 ...
