Abstract

The invention discloses a method and a device for generating dynamic passwords, which relate to the field of identity authentication. The method includes the following steps: a card-reading terminal establishes connection with an intelligent card, and the device is electrified; the card-reading terminal sends a first command to the intelligent card, and receives the first command response of the intelligent card; the card-reading terminal sends a second command to the intelligent card, and receives and parses the second command response returned by the intelligent card to obtain an application file list; according to the application file list, a reading record command is generated and sent to the intelligent card; the reading record command response returned by the intelligent card is received and parsed, so that a second data request list is obtained; second data are generated according to the second data request list; a third command is generated and sent to the intelligent card, and the third command response returned by the intelligent card is received; and the third command response is compressed and converted into a dynamic password which is then outputted. The invention provides the security of dynamic passwords.

Description

technical field [0001] The invention relates to the field of identity authentication, in particular to a method and device for generating a dynamic password. Background technique [0002] With the development of the network, more and more activities of people rely on the network, such as online banking, telephone banking, etc. Network information security is closely related to people's interests, and identity authentication technology has also developed accordingly, which is more secure than static passwords The unique identity authentication method-the dynamic password authentication method is also more and more subject to people's favor. [0003] At present, the dynamic password is generally generated by the server and sent to the user in the form of a short message or email, or generated by a dynamic password token held by the user. If the text message or email is illegally intercepted or the dynamic password token is used by illegal users, or the data is tampered with w...
