Embodiment Construction

[0079] The technical solutions provided by the present invention will be described in detail below in conjunction with specific examples. It should be understood that the following specific embodiments are only used to illustrate the present invention and not to limit the scope of the present invention.

[0080] In the present invention, the system runs at the application layer, and can accurately capture upper-layer semantics, thereby identifying malicious behaviors, and automatically patching such behaviors; at the same time, using two-way control, it can identify richer types of attacks and has strong capabilities. Analysis and protection capabilities. Based on this, the present invention provides an automated patch system based on attacks between Android applications, the architecture of which is figure 1 The system shown is mainly composed of four modules-initialization configuration module, path extraction module, code location module and code patch function module. The aut...

Abstract

The invention discloses an inter-android application attack-based automatic patching system and method. The method comprises a configuration initialization step, a path extraction step, a key point locating step and an inter-application attack patching step. According to the automatic patching system and method, the system runs in an application layer, upper-layer semanteme can be captured very accurately to identify a malicious behavior, and automatic patching is performed for the behavior; two-way control is used, relatively rich attack types can be identified, and relatively good analytic protection capability is achieved; a mode of combining static analysis with dynamic protection is adopted, so that the deficiency of a conventional method for the malicious behavior in an application is overcome; and a protective method for inter-application malicious attack is provided, so that a protective effect is comprehensive and effective.

Description

Technical field [0001] The invention belongs to the technical field of computer security protection, and specifically relates to an automated patch method applied to an Android platform and a system for implementing the method. Background technique [0002] In recent years, with the continuous improvement of the functions of smart phones, the penetration rate of smart phones has increased. As an open source operating system, Android has occupied 83% of the market share in 2015. Due to its absolute dominance and its open source features, Android devices have also become the target of many malicious attackers. The imperfections of the Android platform or the unintentionally exposed interfaces of the developers can cause inter-application attacks. As a type of attack method on the Android platform, inter-application attacks have recently been used in many attack scenarios. However, there are currently no better protection measures to deal with such attacks, which exposes Android ...
