Abstract
A disposable password is necessary to avoid any danger by the use of a static password and reinforce the user's authentication. In order to prevent personal information from being exposed, OTP generation algorithm is regarded as important. The OTP generation algorithm we suggest in this thesis generates 256-bit-size OTP Data by using Seed value and Time value. This value that the generated OTP Data are arranged with a matrix and a 32-bit-value is extracted on an irregular basis becomes the final value. We can find out that the more OTP generation frequency we have, the lower probability of clash tolerance we get in our suggested algorithm, compared to the previous algorithm.
