Mobile terminal physical-button isolation security module security risk preventing device

Abstract

The invention discloses a mobile terminal physical-button isolation security module security risk preventing device which comprises a security module, a physical switch, a verification module, a hardware equipment communication interface, a mobile terminal operation system and an application module. The information security module and the mobile terminal are isolated or communicated through the physical switch, so that the information security module can realize data communication according to mobile terminal users' will, communication connection is disconnected thoroughly after using, and security risks caused by malicious software and loopholes in a mobile terminal system or illegal access to the information security module from the back door are prevented.

Description

technical field [0001] The invention relates to a communication security device in the field of computer technology, in particular to a device for preventing security risks by isolating a security module with a physical button of a mobile terminal. Background technique [0002] With the development of the mobile Internet, more and more software in mobile terminal systems supports mobile finance, mobile securities, and advanced encryption. These software need to call hardware security modules to implement data encryption algorithms or store / read confidential information. However, malicious software such as viruses and Trojan horses emerge in endlessly on mobile terminals and are pervasive. Even if the user closes the software using the security module, the malware is likely to hide in the background, intercept the access password of the security module, and connect to the security module privately to steal secret information or Access to encrypted functions that pose a seriou...

This patent still adopts the technical means of the traditional firewall, and controls the intrusion of malware by downloading the virus in the network cloud in real time and comparing the information of the firewall to control the intrusion of malware. Once a virus or malicious program appears, the isolation function of the isolation device may be possible It cannot be realized, resulting in the loss of important system data. At the same time, it is an unsafe data protection method to connect system sensitive data to the network in real time and only rely on firewall protection.
