Setting method, setting system, terminal and authentication server for dynamic token key factor

Abstract

The invention discloses a setting method, a setting system, a terminal and an authentication server for dynamic token key factors. The method can comprise the following steps that a dynamic token generates key data and key factors are obtained according to the key data; the dynamic token displays the key data through a display device; the authentication server scans the display device of the dynamic token to obtain the key data; and the authentication server obtains the key factors according to the key data. In the invention, the key factors or key factor parameters set on the dynamic token are transmitted to the authentication server by a scanning mode and the limitation of a manual input mode on the digit number of the key factors or the key factor parameters is eliminated, so that the key factors or the key factor parameters with a larger digit number can be set, the difficulty in cracking the key factors is improved, and the safety of the dynamic token is improved.

Description

technical field [0001] The invention relates to the field of information security, in particular to a method, system, terminal and verification server for setting a dynamic token key factor. Background technique [0002] With the development of information security technology, dynamic tokens have been more and more widely used in the fields of financial securities, e-commerce and enterprise software. However, in the existing dynamic tokens, the security parameters are generally set by the manufacturer of the dynamic token terminal equipment when leaving the factory, and both the manufacturer and the issuer will know the security parameters, so it is easy to damage the user's dynamic token terminal due to leakage. The equipment was copied illegally, resulting in losses. [0003] Currently, it is more commonly used to divide the setting of the security parameters into two parts, one part of the security parameters is set by the manufacturer, and the other part is set by the i...

AI Technical Summary

Problems solved by technology

It is set by the issuer or the user, basically through the key input of the dynamic token terminal device. If the input security parameter is too short, such as 8 numbers, it is easy to be cracked by the internal staff of the manufacturer, and the issuer can be obtained. The security parameters input by the manufacturer or the user, plus the security parameters set by the manufacturer, can also illegally copy the dynamic token terminal device

If the input security parameters are very long, although it can increase the difficulty of being cracked by brute force, the workload of user input will be relatively large, and the user experience will deteriorate
