The invention relates to a system comprising a user equipment, a server and a mobile device, wherein :
- The user equipment sends a request for authentication to the server, said request for authentication comprising an identifier of a user of the user equipment and a first authenticating parameter of said user,
- Based on the identifier of the user and the first authenticating parameter, the serve retrieves an encryption key associated to the user,
- The server encrypts a second authenticating parameter associated to the user of the user equipment using the encryption key associated to the user of the user equipment,
- The server encodes said encrypted second authenticating parameter in the form of a multi-dimensional code,
- The server transmits said multi-dimensional code to the user equipment,
- The user equipment displays said multi-dimensional code on a display of the user equipment;
- the mobile device decodes the multi-dimensional code, and decrypts the second authenticating parameter using a decryption key associated to the user of the user equipment stored on the mobile device,
- the user equipment detects on a user interface of the user equipment an input representing the decrypted second authenticating parameter displayed on a display of the mobile device,
- the user equipment transmits a message to the server comprising the decrypted second authenticating parameter,
- If the decrypted second authenticating parameter transmitted by the user equipment equals the second authenticating parameter stored in the server, the server establishes the secured communication session. |
