Abstract(in English) | Nowadays, the leakages of authentication information such as password from web service are happened frequently. MILAGRO-MFA is user authentication that third parties issue user’s secret key and servicer can authenticate users without user’s authentication information. MILAGRO-MFA could prevent the leakages. However, on the previous key issue method of MILAGRO-MFA, servicer has to make issue request by key that the servicer holds. So, if an adversary gets or misuses the key for the issue request, he can issue user’s secret key freely. In this paper, I add a new server “issue request authority” to the previous system architecture of MILAGRO-MFA. I propose a new system architecture which user’s secret key is issued when a servicer and issue request authorities make an issue request. Then, I evaluate the safety of the proposal system architecture. As a result, the proposed system architecture has the safety of prevention of issue request that an adversary issue. |
