Problems solved by technology

[0005] However, the dynamic password card and U-shield have the following defects: for users who use the dynamic password card or U-shield, they must carry the dynamic password card or U-shield with them when conducting electronic transactions; The client certificate is used at the same time, otherwise electronic transactions cannot be carried out
Therefore, for users, electronic transactions cannot be performed anytime and anywhere, which limits the application environment for users to conduct electronic transactions

Embodiment Construction

[0027] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0028] At present, a mobile terminal (such as a mobile phone) has become a portable communication tool commonly used by various groups of people. A data card installed in a mobile terminal, such as a Subscriber Identity Module (Subscriber Identity Module; SIM card for short) or a SIM extension card, is a smart chip with functions such as storage, programming, and processing. SIM expansion card, also known as card sticker, is a contact conversion sheet designed to adapt to the corresponding SIM card slots of different mobile terminals. When in use, align the contacts of the SIM card chip with the contacts on the card, glue the two together, and then directly insert the "bonded" card into the SIM card slot of the mobile terminal. Therefore, the present invention utilizes the advantages of the mobile terminal and the dat...

Abstract

The invention discloses a method and a device for generating dynamic passwords and a network system. The method for generating the dynamic passwords comprises the following steps: receiving request information for acquiring a dynamic password used for the authentification of a user, wherein the request information is sent by a mobile terminal, wherein the request information is sent by the mobile terminal and carries dynamic password generation parameters when the user triggers the mobile terminal to acquire the dynamic password after a server prompts the user to submit the dynamic password; generating a corresponding dynamic password by using a preset dynamic password generating algorithm according to the stored personal certification information of the user and the dynamic password generation parameters; and returning the dynamic password to the mobile terminal, wherein the dynamic password is used by the user to request the server to authenticate the identity. The method and the device are suitable for the user to submit the dynamic password to the server for the identity authentication when the user logs in and visits the server through a client browser or client software, or performs an electronic transaction.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a dynamic password generation method, a dynamic password generation device and a network system. Background technique [0002] With the rapid development of communication technology, electronic transactions based on the Internet and mobile networks have become an important business model for banking transactions. For example, a user may log in to a WAP website through a mobile terminal supporting Wireless Application Protocol (WAP) technology to perform online banking transactions. In order to ensure the reliability and security of electronic banking transactions, authentication based on user identity information has become a core issue in online banking transactions. At present, major commercial banks mainly use dynamic password cards and USB-shields as electronic banking security media for user identity information authentication. [0003] A dynamic password card is a c...
