Embodiment Construction

[0054] The present invention will be further described below in conjunction with the accompanying drawings.

[0055] The security framework uses static code detection technology to determine the security level of the program and the program's security holes, and uses dynamic active defense technology to realize the real-time withdrawal of the permissions given to the application program during installation according to the user's choice.

[0056] Static code detection technology is adopted on the platform side, and we have designed a security detection client (HIT_Security Guard) to realize dynamic and active defense. The overall structure of the framework is as figure 1 and 2 Shown:

[0057] On the platform side, before the source code of MoSync is packaged, the semantic verification of the source code is firstly performed using model checking technology. First, use the multi-pattern matching algorithm to determine the security level of the program (this step is mainly to ...

Abstract

The invention provides a safe development method for application middleware of a mobile internet intelligent terminal. The safe development method includes: A, modeling: A1, determining the safety level of a program through a multi-pattern matching algorithm and screening out a subfunction containing sensitive application program interfaces (API), A2, analyzing the subfunction, and A3, constructing a system migration picture of the subfunction to complete modeling of the system; B, specification: using standard language complementary transistor logic (CTL) to describe malicious actions of a program to construct a syntax tree of a CTL formula, and performing translation, analyzing, EF replacing and variable binding on the CTL formula; and C, verification: using a non-recursive marker algorithm to achieve model verification. The safe development method for the application middleware of the mobile internet intelligent terminal remedies shortcomings of traditional Android systems in authority endowment and can effectively protect safety of user private data, actual active defense is achieved, and all access to the private data needs to be chosen by users.

Description

technical field [0001] The present invention relates to the field of mobile Internet security, in particular to the field of security of smart terminal application middleware development. Background technique [0002] Existing smartphone systems cannot withdraw permissions and cannot control the sequence of API calls, which leads to security issues such as theft of users' private data. Contents of the invention [0003] In order to solve the problems in the prior art, the present invention uses static code detection technology to detect sensitive functions in the developer's code during the packaging and compiling stage of the developer's project, and marks the source code with a security level; the adopted technologies include: Pattern matching technology (AC), model checking technology, lexical analysis, syntax analysis, single pattern matching technology (KMP). [0004] In the software running stage, dynamic defense technology is used to detect sensitive APIs and sensi...
