Abstract

The invention discloses a dynamic token with the key protection function and a working method of the dynamic token and belongs to the technical field of keys. The dynamic token comprises a master control module, a key module, a key forbidden timing module and a key abnormity timing module, wherein the master control module comprises a clock unit, a timing interrupt unit, an input interrupt unit and an input/output unit. The working method includes the steps that when the dynamic token detects that input interrupt happens to the input interrupt unit, the dynamic token is awakened, and input awakening identification is set; when the dynamic token detects that timing interrupt happens to the timing interrupt unit, the dynamic token is awakened, and timing awakening identification is set; if key awakening identification is set, key operation is executed, and if the timing awakening identification is set, the key protection procedure is executed. Through the technical scheme, power consumption caused by abnormal key operation on the dynamic token can be reduced, and the service life of the dynamic token is prolonged.
