Abstract
A method for authenticating a user on a transportation vehicle, wherein the transportation vehicle is coupled to an external device storing an authentication secret code and to at least one token storing a token secret code. In the method the token secret code is transmitted to the transportation vehicle when an operator control action performed with the at least one token is sensed. A new secret code is generated from the token secret code and is compared with the authentication secret code. When the new secret code matches the authentication secret code, the user is authenticated on the transportation vehicle. Also disclosed is an apparatus for authenticating a user on a transportation vehicle.
Claims16
An apparatus for authenticating a user on a transportation vehicle, the apparatus comprising a control apparatus coupleable to an external device and at least two tokens, wherein the external device stores an authentication secret code, a first token stores a first token secret code and a second token stores a second token secret code, wherein
- the first token secret code of the first token is received by the transportation vehicle via a secure channel,
- the second token secret code of the second token is received by the transportation vehicle via a secure channel,
- a first computation apparatus generates a new secret code from the received token secret codes, and
- the user is authenticable on the transportation vehicle when the new secret code matches the authentication secret code;
- wherein the tokens each have a sensing device that senses an operator control action performed with the respective token, and
- wherein the first or second token secret code is transmittable to the transportation vehicle when the operator control action performed with the token is sensed.
A method for authenticating a user on a transportation vehicle coupleable to an external device and to at least two tokens, wherein the external device stores an authentication secret code, a first token stores a first token secret code and a second token stores a second token secret code, the method comprising:
- receiving the first token secret code of the first token by the transportation vehicle;
- receiving the second token secret code of the second token by the transportation vehicle;
- generating a new secret code from the received token secret codes;
- and
- authenticating the user on the transportation vehicle in response to the new secret code matching the authentication secret code;
- wherein an altered new secret code is generated directly after or during the generation of the new secret code, and
- wherein the new secret code is stored in the transportation vehicle only until the altered new secret code is generated.
A transportation vehicle that includes an apparatus for authenticating a user on a transportation vehicle, the apparatus comprising a control apparatus coupleable to an external device and at least two tokens, wherein the external device stores an authentication secret code, a first token stores a first token secret code and a second token stores a second token secret code, wherein
- the first token secret code of the first token is received by the transportation vehicle via a secure channel,
- the second token secret code of the second token is received by the transportation vehicle via a secure channel,
- a first computation apparatus generates a new secret code from the received token secret codes, and
- the user is authenticable on the transportation vehicle when the new secret code matches the authentication secret code;
- wherein the tokens each have a sensing device that senses an operator control action performed with the respective token, and
- wherein the first or second token secret code is transmittable to the transportation vehicle when the operator control action performed with the token is sensed.
