Abstract: 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.

Abstract: 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.
