摘要：Device and method are provided for multiple server customer discriminatingpin. A kind of No. 1 access control server 2 of command identifying includes for thecomputer 3 with user via network 4. User of the control of access control server 2 accessby the password associated with resource 5 of subscriber computer 3 dependent onrelative users identifies IDs. System 1 further includes the certificate server 6 of multiplen, stores corresponding secret value, is used for access control server 2 via network 4.Each User ID, the first ciphertext that the storage of access control server 2 generatesdepend on the authentication server 6 of secret value using scheduled algorithm byencryption user password and this ID. Access control server 2 and certificate server 6 areadapted so that, in response to receiving the input of User ID from the user and 3, thecertificate server 6 of access control server 2 and multiple k ＜ n realize passwordauthentication protocol, it needs to pass through their own secret value using kauthentication servers, wherein the second ciphertext encryption input password to usethe first and second ciphertexts using the scheduled algorithm and access control server2, to determine whether the password of input is equal to the received User ID of userpassword. If it is, access control server 2 allows user 3 to access resource 5.
