Abstract: A person to be authenticated generates authentication data for this time and authentication data for next time using a one-way function, based on a user ID, a password and a random number, and performs an exclusive OR operation on these, to thereby encrypt the data while associating the both parameters with each other, and transmits these data together with the own user ID to an authenticating person. The authenticating person receives the aforesaid three informations, compares a validity confirmation parameter calculated by using a one-way function based on the authentication data for this time with a authentication parameter registered in the previous authentication phase, and when these parameters agree with each other, judges that authentication is approved, and registers the authentication data for next time as the authentication parameter for next time.

Abstract translation: 要认证的人员根据用户ID，密码和随机数，使用单向功能生成此时的认证数据和下次的认证数据，并对其进行异或运算，从而对 同时将两个参数彼此关联，并将这些数据与自己的用户ID一起发送给认证人。 认证人接收上述三个信息，将通过使用单向功能计算出的有效性确认参数与此时的认证数据进行比较，并将其与在先前认证阶段中登记的认证参数进行比较，并且当这些参数彼此一致时， 判断认证是否被批准，并下次登录认证数据作为认证参数。
