A study of implementation of SAS (Simple and secure) authentication on mobile terminal

摘要

Recently, a number of applications which we can use from mobile terminal via the Internet have been developed. But, efficient and simple user authentication method is not provided. SAS (Simple and Secure) Authentication Method enables secure authentication with light-process and simple operation. So it is the best solution for authentication on mobile terminal. But when we implement SAS authentication, we must solve two major problems. One is the way of the initial user registration, and the other is the way to manage synchronization. We have solved above two problems, by importing "Serial number" for initial registration, and using "counter" for managing synchronization. So finally, we have succeeded in the implementation of SAS authentication as "i-appli" modules on mobile phone.
