Description
Technical field
The present invention relates to a kind of Computer Applied Technology, specifically relate to a kind of USB KEY of embedded Control technology, mobile communication technology and modern encryption technology through 3G module independent transmission information.
Background technology
The appearance of Global Internet, the mutual authentication mode of electronic form just progressively replace aspectant and authentication mode papery, and the demand of safety certification and information security is more and more urgent.When yet present most of user carries out business operation during through the Internet; Need to encrypt through USBKEY earlier or the signature related data; Then with these metadata caches in computer system, afterwards these data are sent to background system through the Internet, because computer system is easy to receive the attack of virus; Bring these safety of data problems, have unpredictable risk.
Behind the integrated 3G wireless module of USB KEY; USB KEY directly sends to background system with these data through network; Computer system can't be obtained these critical datas, has promoted the security performance of system significantly, when transmission, does not also take the system for computer resource simultaneously.For this reason, this patent has proposed a kind of USB KEY through 3G module independent transmission information.
Summary of the invention
The purpose of this invention is to provide a kind of USB KEY through 3G module independent transmission information.
The objective of the invention is to realize by following mode; System is divided into CA and encryption section and wireless Internet access part; CA and encryption section are made up of Z32 encryption chip, crystal 1, USB slave unit interface, battery, clock chip, NANDFLASH; The part of getting online without being tethered to a cable is made up of arm processor, crystal 2, SDRAM, NorFLASH and 3G module; In CA and encryption section, crystal 1, USB slave unit interface, battery, clock chip, NAND FLASH are connected with the Z32 encryption chip through data wire, are connected with arm processor through data wire at wireless Internet access part crystal 2, SDRAM, NorFLASH and 3G module; Arm processor is connected communication through serial ports with the Z32 encryption chip; CA and encryption function through Z32 security chip controller realization USB KEY realize that through ARM controller and 3G module USB KEY does not rely on the wireless networking capabilities of computer system, and Z32 and ARM pass through serial communication; The enciphered data that generates realizes Network Transmission through ARM and 3G module; The Z32 security chip controller crucial enciphered data that it is inner directly is sent to background system through the 3G module, and need not these crucial enciphered datas are sent to background system through computer system, thereby has guaranteed the fail safe and the real-time of user's online transaction.
Excellent effect of the present invention is: adopt Z32 to realize the functions such as CA and encryption of USB KEY, realize the wireless networking capabilities of USB KEY through ARM and 3G module.This USB KEY does not take the Internet resources of computer, can satisfy user's demands such as online transaction, has solved the systematic risk that factors such as computer virus cause, thereby has guaranteed the fail safe and the real-time of user's online transaction.
The Z32 security chip controller is that ZTEIC is towards the safety governor application market; Multifunctional safe processing platform based on homemade 32 risc processors; Can realize function such as signature and authentication, tailor-made algorithm download execution and high data rate encryption and decryption on key management on the sheet, the sheet; Integration USB interface on the sheet, can with the usb host direct communication.This patent adopts the Z32 chip to realize the functions such as CA and encryption of USB KEY, satisfies demands such as user identity identification and data encryption.Because the user receives the influence of factors such as computer virus easily based on the computer log the Internet, has unpredictable systematic risk, might cause on a large scale or the partial mass user can't surf the Net.The USB KEY integrated wireless function of surfing the Net that proposes of this patent for this reason; Adopt existing 3G module; The ARM platform uses (SuSE) Linux OS, and 3G combines with ARM, realizes the wireless Internet access based on the Linux embedded OS; Satisfy the demand of user's anywhere and time period online, guaranteed the fail safe and the real-time of online transaction and application.
Contrast prior USB KEY solution; A kind of USB KEY innovative point through 3G module independent transmission information that this patent proposes is: the mode that adopts Z32, ARM to combine with the 3G module; Realize data encryption and the wireless networking capabilities of USB KEY, solved the user and adopted the computer log the Internet, be subject to the influence of factors such as computer virus and network failure; Guarantee the real-time and the fail safe of user's online transaction, had advantages such as the simple and fail safe height of circuit.
