Yatsukawa introduced the Insider-Resistant One-Time Password (IROTP), which is an authentication protocol intended to be secure for attacks by insiders. In the IROTP, the RSA decryption function factors recursively on a seed, and its security depends on the period of the sequence generated by recursive factoring of the RSA decryption function. We have found a condition which gives a sufficient long period for the RSA decryption function. In other words, we have proved that the IROTP, with certain parameters, is secure for attacks utilizing the period. We have also found an algorithm to find such parameters.
