A temporary password production method and an authentication system of a time-synchronized challenge-response method for increasing security are provided to generate other responses by adding time data to input value. A controller connects a challenge, a serial, a discretized time data and a reservation code. The controller prepares for a hash input data block(1000). The controller inputs the hash input data block to a hash function module(411). The controller draws a hash result. The controller inputs the hash result to a representing function module(412). The controller draws an OTP(One Time Password)(1100). |
