Patent ID: 11064358

Abstract:
A one-time-password authentication method, comprising the following steps: a client establishes NFC with an NFC dynamic token, obtains a token serial number of the NFC dynamic token and a one-time-password from the NFC dynamic token; the client encrypts the one-time-password by using the token serial number and a second random number stored by the client, to obtain a third ciphertext, and sends the third ciphertext, the second random number, and the token serial number to a token server; the client receives an authentication success message or an authentication failure message returned from an application server. By means of the present invention, the one-time-password generated by the NFC dynamic token is obtained by using an NFC channel, and the one-time-password is sent to the token server for authentication. Therefore, errors and leakage caused by a user by manually inputting the one-time-password is avoided, and the security of the dynamic token is improved.
