Abstract:
1. An authentication method in a password server, the method comprising: generating a password; determining an initial portion of the password and a remaining portion of the password; calculating a value that is a function of the password; sending the initial portion to a mobile communication device for output thereby; sending the remaining portion to a password client; receiving a value from the password client; comparing the value received from the password client and the value calculated at the password server; if the value received from the password client matches the value calculated by the password server, determining that the password client has successfully received the initial portion as output by the mobile communication device and the remaining portion from the password server, and therefore determining that authentication has succeeded; and if the value received from the password client does not match the value calculated by the password server, determining that authentication has failed.
