THE METHOD FOR CORRECTING A REAL-TIME CLOCK(RTC) OF AN OTP GENERATOR, THE SYSTEM, OTP GENERATOR AND OTP ERROR RATE MEASUREMENT MODULE THEREOF

摘要

The present invention relates to a real-time clock (RTC) correction method of an OTP generator, a system thereof, an OTP generator, and an OTP error rate measurement module, and the correction method according to an embodiment of the present invention includes an OTP error rate measurement module. Measuring an error rate of the generator; Storing the error rate and a reference time when the error rate is measured in an OTP generator; And correcting, by the OTP generator, the time of the OTP generator based on the error rate and the reference time. Therefore, it is possible to increase the accuracy of the authentication method according to the OTP generator.
