METHOD AND APPARATUS FOR DETERRENCE OF SECURE COMMUNICATION USING ONE TIME PASSWORD

摘要

A communications system and a method thereof for providing the enciphered communications of the light weight are provided to simplify a key generation management part by using an OTP generating unit. An OTP generator(120) produces OTP(One Time Password). A first encryption communication module(110) transmits user information and OTP value to a service server. The first encryption communications module transmits the OTP value and user information of the OTP generator for the user authentication to a service server. The first enciphered communications module performs the enciphered communications with the service server through data which are encrypted by using the OTP value. A first timer measures the use time of the session opened for the enciphered communication.
