A method for updating seed data in a dynamic token comprises: an interaction interface sends user information to an application server for verification, receives a verification result returned by the application server, continuously receives dynamic token information when the verification result is valid, and sends same to the application server; the application server generates a request data packet containing the dynamic token information and application information and sends same to an authentication center; the authentication center acquires seed data corresponding to the dynamic token information and the application information and sends same to the application server; the application server converts the seed data into photosensitive data and displays same by means of the interaction interface; and the dynamic token obtains the seed data by acquiring the photosensitive data. The present invention can realize that the seed data in a dynamic token is automatically updated by a user, and meanwhile, a dynamic token can be applied to multiple applications.

Method for updating seed data in dynamic token

Disclosed is a working method for a multi-seed one-time password, which falls within the field of information security. The method comprises: powering and initializing a one-time password, opening a total interrupt, initializing the state of a system, and then entering a sleep mode; when the one-time password detects the interrupt, awakening the one-time password from the sleep mode, and entering an interrupt processing flow; after the interrupt processing flow is ended, checking each awakening flag; and executing a processing flow corresponding to the set awakening flag. According to the present invention, a user can burn seed data into the one-time password by operating the one-time password, and can update the seed data in the one-time password. In addition, according to the present invention, the one-time password is capable of storing and managing a plurality of seeds. In a process of using the one-time password, a one-time command can be generated using the corresponding seed data according to the selection from the user, which is convenient for the user to use. In addition, the reliability and security of the seed data are guaranteed by means of binding between a unique identifier of the one-time password and the seed data.

Working method for multi-seed one-time password

An operating method for a one-time password with an updatable seed. The method comprises: a one-time password entering a dormancy mode after being powered on and initialized; being woken up when an interrupt is detected; entering an interrupt processing flow; setting a wakeup flag; entering a key processing flow when a key wakeup flag is set; judging a system state and a key manner; and completing the functions of programming seed data and generating a password according to a judgment result. According to the present invention, on the premise of guaranteeing the security, a user is permitted to program and update seed data in a one-time password, thereby facilitating the use of the user.
