The invention comprises a method for secure login in a communication system including a mobile unit, a mobile communication network, an authentication center, an application server, a computer and an untrusted network, wherein the user sets up an application session via a data communication from his personal computer to an application server and submitting an identity. Thereat, the server requests authentication from an authentication center. Then, the authentication center sends a simple token to the server, which sends said token to the user over the data connection. Finally, the user reads the token on the screen of his personal computer and sends the token as a text message from the mobile unit to the authentication center, which also obtains the mobile phone number and the cell identification of the user. An advantage of the disclosed method is that no extra pin-code is required. <IMAGE> |
