Embodiment Construction

[0033] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0034] In the embodiment of the present invention, the dynamic token issuing device may be a dynamic token server, or other devices capable of data interaction with the dynamic token server and generating key data, such as PCs and mobile terminals.

[0035] refer to figure 1 , propose an embodiment of the method for setting the dynamic token key factor of the present invention, including:

[0036] Step S10, the second smart key device receives the key data output by the first smart key device;

[0037] In this embodiment, the second smart key device can receive key data in the following two ways:

[0038] Mode 1, the second smart key device receives the key data through the brightness, brightness change, color and / or color change of the screen of the first smart key device, refer to figure 2 , including the steps:...

Abstract

The invention discloses a method and a device for setting cryptographic key factors of dynamic tokens, wherein the method comprises the following steps: receiving cryptographic key data outputted by a first intelligent cryptographic key device by a second intelligent cryptographic key device; and generating cryptographic key factors according to the cryptographic key data. By using the method and the device provided by the invention, the sealing of a dynamic token can be achieved without arranging an opening which is used for programming cryptographic key factors on a shell of the dynamic token.

Description

technical field [0001] The invention relates to the technical field of data security, in particular to a method and device for setting a dynamic token key factor. Background technique [0002] With the development of social economy, people have more and more demands for online transactions. In order to protect the security of online transaction accounts, people will choose to buy dynamic tokens (one-time password devices) and use the dynamic passwords generated by them to replace traditional static password. The current dynamic tokens on the market need to burn the key factor through contact communication during issuance, so the shell must have an opening, so it cannot be waterproof and dustproof. Contents of the invention [0003] The main purpose of the present invention is to provide a method and device for setting the key factor of the dynamic token. By setting the key factor through this method, there is no need to set an opening for programming the key factor in the...
