WIRELESS AUTHENTICATION SYSTEM AND WIRELESS AUTHENTICATION METHOD

摘要

A wireless authentication system includes an execution end device and a control end device. When the execution end device and the control end device receive an activation signal, the execution end device generates a time related random code, and transmits the time related random code to the control end device; and the control end device generates a comparison authentication code according to the time related random code, a fixed password and a variable password. When the execution end device determines that the comparison authentication code corresponds to a set of data stored in the execution end device, the execution end device performs a predetermined operation, and the variable password is changed.

1. A wireless authentication system, comprising:
an execution end device, comprising:
a first wireless module; anda first control unit coupled to the first wireless module; and a control end device, comprising:
a second wireless module; anda second control unit coupled to the second wireless module; wherein when the first wireless module receives an activation signal, the first control unit generates a time related random code, and the first control unit transmits the time related random code to the second wireless module via the first wireless module; wherein when the second wireless module receives the activation signal and the time related random code, the second control unit generates a comparison authentication code according to the time related random code, a fixed password and a variable password, and transmits the comparison authentication code to the first wireless module via the second wireless module; and wherein when the first control unit determines that the comparison authentication code corresponds to a set of data stored in the execution end device, the first control unit performs a predetermined operation, and the variable password is changed.
