Problems solved by technology

Among them, a lot of use includes a challenge-response dynamic password system. This method uses a small intelligent security device with buttons, which can also be called a dynamic password token. The token has a built-in security algorithm, and each token is set There is a unique seed (used to calculate the static parameters of the dynamic password), usually, the token is provided with buttons and a display screen, the buttons are used as an input device to input challenge codes, etc. The seed in the token is confidential and stored in the token and cannot be read out. Hackers cannot crack the user's dynamic password if they cannot obtain the seed.

Example Embodiment

[0054] Example 1

[0055] This embodiment provides a method for updating the seed of a dynamic password token. figure 1 ,Specific steps are as follows:

[0056] Step 101, the user sends a request for updating the seed in the dynamic password token to the server through the client;

[0057] In this embodiment, the dynamic password token used by the user is a challenge-response type dynamic password token, and an input and output device is installed on the token. Preferably, the input device adopts a keyboard, and the output device adopts display output or audio broadcast. way to output;

[0058] The user sends a request to update the seed in the dynamic password token through the client. Specifically, the user accesses the server through the browser installed in the client, and the server returns the function of updating the seed to the dynamic password token through the browser. page, the user enters the number of the dynamic password token that needs to update the seed, se...

[0086] Example 2

[0087] This embodiment provides a method for updating the seed of a dynamic password token. figure 2 ,Specific steps are as follows:

[0088] Step 201, the user sends a request for updating the seed in the dynamic password token to the server through the client;

[0089] In this embodiment, the dynamic password token used by the user is a challenge-response type dynamic password token, and an input and output device is installed on the token. Preferably, the input device adopts a keyboard, and the output device adopts display output or audio broadcast. way to output;

[0090] The user sends a request to update the seed in the dynamic password token through the client. Specifically, the user accesses the server through the browser installed in the client, and the server returns the dynamic password token through the browser to update the seed. On the function page, the user enters the number of the dynamic password token that needs to update the seed, sel...

Example Embodiment

[0118] Example 3

[0119] This embodiment provides a method for updating the seeds of a dynamic password token. In the dynamic password token provided by this embodiment, multiple seeds are stored in the dynamic password token, and stored corresponding to the multiple seeds The list, which is called the seed list in this embodiment, is written when the dynamic password token is produced or initialized. When the dynamic password token leaves the factory, one of the multiple seeds is used as the initial seed to calculate the dynamic password. The seed is defined as the initial seed, and the same seed list is also stored on the server side for the numbered dynamic password token. image 3 , as follows:

[0120] Step 301, the user sends a request for updating the seed in the dynamic password token to the server through the client;

[0121] In this embodiment, the dynamic password token used by the user is a challenge-response type dynamic password token, and an input and output ...

Abstract

The invention discloses a method for updating seeds of a dynamic password token. The method comprises the following steps: firstly, a user performs mutual authentication by using a dynamic password token and a server, and seeds in the dynamic password token are updated if legal; the server generates a seed updating identification and transmits the seed updating identification to a client; the dynamic password token uses the seed updating identification to generate a temporary seed and authenticates a dynamic password again by using the temporary seed, and updates the seeds stored inside if the authentication is successful; and the server also updates the seeds to be stored by the dynamic password token. The invention prevents token manufacturers from knowing the condition of seeds in eachtoken by updating seeds in the dynamic password token, therefore the safety is improved.

Description

technical field [0001] The invention relates to the field of information security, in particular to a method for updating the seed of a dynamic password token. Background technique [0002] With the development of network technology, people need to transmit a large number of important information such as transactions on the Internet, but ordinary static password technology is no longer safe, and can be easily intercepted by hackers. Hackers use static passwords to log in to users' legitimate accounts. , Carrying out illegal activities poses a great threat to people's information security. [0003] In recent years, a dynamic password technology has emerged. Through this technology, the feature of one-time encryption can be achieved during the process of user inputting the password. Even if the user's login password is intercepted this time, the password will be invalidated when the user logs in next time. It cannot be used and can no longer pose a threat to users, which grea...
