Multipoint Hook reversing method for Android reinforcing application

ActiveCN106203120AGuaranteed validity and reliabilitySame functionPlatform integrity maintainanceVirtual machineAnalysis method
The invention discloses a multipoint Hook reversing method for an Android reinforcing application, and belongs to the field of information security. The method comprises the following specific steps that firstly, a certain tested Android application is loaded to an internal storage; a plurality of different function entry points are selected for Hook operation at the same time in the loading process, and corresponding Hook points are loaded for all functions respectively; when a virtual machine executes different functions, the class structures ClassLoader called by the functions are called through the Hook points; then, the deviation positions of the functions and the classes of the functions in the internal storage are acquired through the class structures ClassLoader, dex source codes of the functions of a program are acquired, a dex file is formed, and restoration and perfection are carried out in the internal storage; finally, the dex file obtained after restoration and perfection is dumped from the internal storage. The method has the advantages that the function entry points are hooked dynamically in the operating process of the application to be analyzed, the defect that dex of a program cannot be completely and accurately acquired through a traditional technology can be avoided, and the complex dex codes hard for a traditional analysis method to obtain are obtained.

Redundant energy acquiring circuit for power module and control method thereof

The invention discloses a redundant energy acquiring circuit for a power module. The power module comprises at least one power semiconductor device, a first capacitor C1 and a first bypass switch K1.The redundant energy acquiring circuit provided by the invention comprises a first Zener diode VD1, a second Zener diode VD2, a second switch K2, a first resistor R1, a second resistor R2, a second capacitor C2, a power supply board card and a control board card. The power supply board card acquires energy form the capacitor C1, supplies power for the control board card and charges the capacitor C2. The control board card controls the first bypass switch K1 to be switched on by triggering the switch K1. According to the scheme provided by the invention, when a fault occurs in the power supplyboard card, the capacitor C2 is charged through utilization of a breakdown characteristic of the first Zener diode, and a triggering command is provided for the switch K2 through utilization of the breakdown characteristic of the second Zener diode. The reliable bypass of the bypass switch is realized under the condition that the fault occurs in the power supply board card. The device running stopunder the condition that the fault occurs in the power supply board card of the power module is avoided. The scheme cost is low. The reliability is high.
