AI summary

The present invention relates to the field of information security. Disclosed are a system and method for communication between a dynamic token and a tool, the system comprising a tool part and a dynamic token part; the tool part comprises a control module and a tool radio frequency communication module; the dynamic token part comprises an MCU and liquid crystal module and an OTP radio frequency communication module. The method comprises: the tool part transmits a modulated wake-up command signal to the dynamic token part in the form of an electromagnetic wave; when a wake-up response command signal returned by the dynamic token part is correctly received, the tool part transmits the modulated command signal to the dynamic token part in the form of an electromagnetic wave; and the tool part detects the amplitude variation of the generated carrier signal, judges whether the response signal is correctly received, and operates correspondingly.
