Network transaction system with dynamic password generator

Abstract

A network transaction system comprises an encryption device, a computer connected with a network, a gateway server and a backstage transaction server, wherein the encryption device is used for identifying a digital certificate and a private key of a client identity, and comprises a dynamic password generator capable of dynamically generating one-time passwords random; the computer is provided with an interface where the encryption device can be plugged in; the gateway server is connected with the computer through the network and used for encrypting data commands of the backstage transaction server, performing ciphertext transmission on the internet, and decrypting and transmitting the received client data commands to the backstage transaction server; and the backstage transaction server is connected with the gateway server and used for processing transaction requirements proposed by the computer. According to the system, the passwords are dynamic and changed random, therefore the possibilities that other people steal a user's password for illegal transaction are reduced greatly, additionally, password cracking difficulty is increased greatly due to complex encryption and decryption algorithms, and the safety of the network transaction system is improved remarkably.

Description

technical field [0001] The invention relates to a network transaction system, more specifically, to a network transaction system with a dynamic password generator. Background technique [0002] With the rapid development of Internet applications, more and more people conduct business transactions on the Internet, such as online shopping, online banking, online games, etc., and the Internet is penetrating into every aspect of people's lives. With the rapid development of network transactions, people have higher and higher security requirements in the process of network transactions, and the issue of security guarantee in the process of network transactions is becoming more and more concerned by network operators and consumers. In the process of traditional online transaction business activities, the user connects to the server from the client, and the server sends identity confirmation information. The user enters the confirmation information through the keyboard on the clien...
