Problems solved by technology

However, after the existing dynamic password generating device receives the challenge code, it directly generates a dynamic password according to the challenge code, and the user does not need to intervene in the whole process. In this way, under the lure of a phishing website pretending to be a bank or e-commerce website, the user is likely to Feedback the generated dynamic password directly to the phishing website, resulting in loss of user property security

Abstract

The invention discloses a dynamic password generating method and a dynamic password generating device, wherein the dynamic password generating method comprises the steps of performing electrification initialization on the dynamic password generating device; buffering a received challenge code; determining whether receiving of the challenge code is finished, if yes, searching a prestored first algorithm which matches a challenge code generating algorithm, and processing the challenge code by means of the searched first algorithm; if transaction information cannot be obtained, ending a dynamic password generating process; if the transaction information is obtained, displaying the transaction information; on the condition that first indicating information is received, judging the type of the first indicating information, if the type of the first indicating information is first canceling information, ending the dynamic password generating process; and if the type of the first indicating information is first confirming information, searching a prestored second algorithm, calculating password generating information which at least comprises the challenge code by means of the searched second algorithm, generating the dynamic password and displaying the dynamic password.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a method and device for generating a dynamic password. Background technique [0002] In order to solve the security problems of authentication methods based on static passwords, dynamic password authentication technology is widely used in authentication scenarios such as online banking, online games, and telecom operators. The dynamic password generation device can be based on three methods: time synchronization, event synchronization, and challenge / response, among which the dynamic password generation device based on challenge / response is the most commonly used. The challenge / response based dynamic password generating device generates a once-effective dynamic password through a built-in algorithm according to the input challenge code, and uses the dynamic password as a password for network transactions and logins. However, after the existing dynamic password generating devi...
