Abstract

The invention discloses a working method for a dynamic token and relates to the field of information safety. The working method comprises the steps of judging a wake-up type when the dynamic token is waken up, and if the wake-up type is key wake-up, enabling a system state to be set as a corresponding state according to the type of a pressed key; if the wake-up type is other wake-up, judging a system state type; if the system state type is a login password generating state, generating a login password according to a secret key and current time and outputting the login password, enabling the system state to be set as a login password display state, and enabling the input data lengths to be set as initial values; if the system state type is a first information processing state, generating a first password according to the secret key, the current time and the input first information and outputting the first password, enabling the system state to be set as a first password display state, and enabling the input data lengths to be set as the initial values; if the system state type is a second information processing state, processing input second information, generating a second password according to processing results, the secret key and the current time and outputting the second password, enabling the system state to be set as a second password display state, and enabling the input data lengths to be set as the initial values.

Description

technical field [0001] The invention relates to the field of information security, in particular to a working method of a dynamic token. Background technique [0002] A dynamic token is a terminal used to generate a dynamic password. The dynamic password can confirm the legal identity of the user, thereby ensuring the security of the user's business access on the basis of the user logging in with a legal identity. Dynamic password authentication technology is considered to be one of the most effective ways to solve user identity authentication at present, so it is widely used in various information system scenarios such as banking, securities, third-party payment, and large enterprises. In the existing technology, as long as you log in to various information system scenarios through a dynamic password, you can operate all items in the information system scenario. Malicious people can illegally operate the information system scenario while the user is away. Less security. ...
