Electronic commerce intelligent password key with button and implementation method for electronic commerce intelligent password key

Abstract

The invention relates to the technical field of information security, and provides an electronic commerce intelligent password key with a button and an implementation method for the electronic commerce intelligent password key. The intelligent password key comprises a universal serial bus (USB) plug, a keyboard and a built-in security encryption intelligent chip, wherein a digital keyboard, a power button, an unlocking button and a light emitting diode (LED) indicating lamp are arranged on the keyboard; the intelligent chip comprises a password processing module for processing the buttons, initializing a user personal identification number (PIN) code, modifying the user PIN code and checking the user PIN code, a USB data transmitting and receiving module for transmitting authentication information and confirming work of equipment, and an encryption and decryption module for encrypting and decrypting user authentication information. By an encryption storage mode, the user authentication information is prevented from being violently cracked; by a digital keyboard hardware authentication mode, the potential security hazards of keyboard Trojan horses and 'screen shot' password stealing Trojan horses are avoided; and therefore, the risk that the PIN code is stolen by the Trojan horse during authentication is reduced, and the intelligent password key is secure and reliable and is low in cost.

Description

technical field [0001] The present invention relates to the technical field of information security, in particular to an intelligent cipher key and its implementation method, in particular to an e-commerce intelligent cipher key with buttons and its implementation method. Background technique [0002] With the development of computer technology and network, e-commerce has been integrated into the life of the world, but it is a virtual space built on the Internet network platform. Both parties to the transaction make judgments and choices through data, symbols, signals, etc. Communication replaces specific business activities, and the security of its transactions is of paramount importance. [0003] The proposal of PKI (Public Key Infrastructure) provides a security guarantee for the development of e-commerce, and has also become the de facto standard for global network transactions. Users can use the services provided by the PKI platform for secure communication. But this s...
