Second generation USB (Universal Serial Bus) key system for implementing safety pavement of mobile terminals

Abstract

The invention relates to a second generation USB (Universal Serial Bus) key system for implementing the safety pavement of mobile terminals, which comprises a USB interface module, a master-slave control module, a safety control module, a battery management module, a display module and a key module. The USB interface module adopts a standard mini UBS3.0 interface; an interface A is a USB2.0 interface for being connected with iOS (Internetwork Operating System)-series and Android-series mobile equipment; an interface B is a USB3.0 interface for being connected with a PC (Personal Computer); the master-slave control module adopts a CH374 chip; the safety control module uses a 3272L chip as a master control chip; the display module uses an A514 chip as a display chip; according to an MFi (Made for iPod/iPhone/iPad) authentication module, an IPOD_AC_2.0C Apple authentication coprocessor is connected with the 3272L chip by an I2C (Inter-Integrated Circuit) interface so as to implement the authentication on the iOS-series equipment; and by the interfaces, the master-slave control module, an online second generation key is connected into the PC, the Android equipment, the iOS-series equipment and OTG (On-The-Go) equipment to implement safety communication among various mobile terminal equipment. The problem of the limitation that the existing second generation key can only be connected into the PC to carry out network payment is solved.

Description

Technical field [0001] The invention relates to the field of information security and mobile payment, in particular to a second-generation U-shield system for realizing secure payment of a mobile terminal. Background technique [0002] USB-Shield is a high-level security tool launched by ICBC to provide users with online banking services. It is used for online banking electronic signatures and digital authentication. It has a built-in micro smart card processor and uses a 1024-bit asymmetric key algorithm to encrypt, decrypt and digitally sign online data to ensure the confidentiality, authenticity, integrity and non-repudiation of online transactions. [0003] Mobile terminal, specifically refers to terminal devices with mobile communication capabilities such as tablet computers, smart phones, and notebooks. Due to their light and fast characteristics, mobile terminal devices have become indispensable tools for people's work and life. However, due to various factors, there is cur...

Problems solved by technology

[0005] The purpose of the present invention is to overcome the deficiencies of the existing second-generation U-shield of online banking and provide a second-generation U-shield system for realizing safe payment of mobile terminals. The second-generation U-shield system is developed on the basis of ordinary second-generation U-shields. It solves the problem that mobile terminal products such as mobile phones and tablet computers cannot use the U-shield of online banking. At the same time, the invention adds an MFi authentication module. MFi authentication is a kind of identification license for external accessories produced by Apple's authorized accessory manufacturers, and supports iOS series products, iOS products are handheld terminal devices with iOS operating system developed by Apple Inc. These products include ipad, itouch, iphone, imac, etc., which meet the operating system of iOS4.0 and above
