Access to a service with authentication based on a mobile terminal

A device for accessing a service on a mobile terminal, contained in the mobile terminal and comprising:

• a multimedia interface for consumption of the service by a user on the mobile terminal,
• a security module,
• at least one transmitter configured to send a request comprising an identifier of a subscriber to a subscription with a mobile operator, the identifier of the subscriber being contained in the request and based on information provided by the security module without the user intervening;
• and
• at least one receiver configured to receive a response comprising information relating to the identifier of the subscriber, called an identification code;
• wherein the at least one transmitter is configured to send an authentication request comprising the identification code to an authentication server of the mobile operator;
• wherein the at least one receiver is configured to receive an authentication response comprising information relating to the identification code, called an authentication code;
• and
• wherein the at least one transmitter is configured to send a request to access the service comprising the authentication code to an application server contributing to providing the service intended to be consumed by way of the multimedia interface.

A system comprising:

• a mobile terminal equipped with a device for accessing a service, the device comprising:
• a multimedia interface for consumption of the service by a user on the mobile terminal,
• a security module,
• at least one transmitter configured to send a request comprising an identifier of a subscriber to a subscription with a mobile operator, the identifier of the subscriber being contained in the request and based on information provided by the security module without the user intervening;
• and
• at least one receiver configured to receive a response comprising information relating to the identifier of the subscriber, called an identification code;
• wherein the at least one transmitter is configured to send an authentication request comprising the identification code to an authentication server of the mobile operator;
• wherein the at least one receiver is configured to receive an authentication response comprising information relating to the identification code, called an authentication code;
• and
• wherein the at least one transmitter is configured to send a request to access the service comprising the authentication code to an application server contributing to providing the service intended to be consumed by way of the multimedia interface,
• the application server configured to provide the service to be consumed by the user on the mobile terminal,
• the authentication server of the mobile operator configured to submit an authentication challenge to the mobile terminal on the basis of the request received from the mobile terminal, and
• a discovery server configured to provide an address of the authentication server on the basis of a request from the mobile terminal transmitted by the application server.

A non-transitory computer-readable information medium able to be read by a mobile terminal and containing instructions of a computer program, which when executed by a processor of a device of the mobile terminal, configure the device to access a service provided on the mobile terminal by an application server contributing to providing the service, wherein the instructions configure the device to:

• send a request comprising an identifier of a subscriber to a subscription with a mobile operator, the identifier of the subscriber being based on information provided by a security module of the mobile terminal, and inserted into the request without the user intervening;
• receive a response comprising information relating to the identifier of the subscriber, called an identification code;
• send an authentication request comprising the identification code, the request being sent to an authentication server of the mobile operator;
• receive an authentication response comprising information relating to the identification code, called an authentication code;
• and
• send a request to access the service comprising the authentication code, the request being sent to the application server.
