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.

An apparatus for authenticating a user of a transportation vehicle, the apparatus comprising:
- a control apparatus coupleable to an external device configured to store an authentication secret code, a first token including a first token secret code, and a second token including a second token secret code;
- and
- a computation apparatus configured to be coupled to the control apparatus,
- wherein the control apparatus is further configured to receive the first token secret code of the first token via a secure channel,
- wherein the control apparatus is further configured to receive the second token secret code of the second token via a further secure channel,
- wherein the computation apparatus is further configured to generate a new secret code by combining the received first token secret code and the received second token secret code in a computation operation,
- wherein the first token secret code and the second token secret code are stored in association with the transportation vehicle on the external device only until the new secret code is generated and stored in association with the transportation vehicle,
- wherein the user is authenticated for the transportation vehicle in response to the new secret code matching the authentication secret code, and
- wherein the new secret code is stored in association with the transportation vehicle on the external device only until the new secret code is compared with the authentication secret code in the external device.
A method for authenticating a user of a transportation vehicle coupleable to an external device configured to store an authentication secret code, a first token including a first token secret code and a second token including a second token secret code, the method comprising:
- receiving the first token secret code of the first token by the transportation vehicle via a secure channel and storing the first token secret code by the transportation vehicle;
- receiving the second token secret code of the second token by the transportation vehicle via a secure channel and storing the second token secret code by the transportation vehicle;
- generating a new secret code by combining the first token secret code and the second token secret code in a computation operation and storing the new secret code on the transportation vehicle,
- wherein the first token secret code and the second token secret code are stored in the association with the transportation vehicle on the external device only until the new secret code is generated and stored in association with the transportation vehicle, and
- authenticating the user for the transportation vehicle in response to the new secret code matching the stored authentication secret code,
- wherein the new secret code is stored in association with the transportation vehicle on the external device only until the new secret code is compared with the authentication secret code in the external device.
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 configured to store an authentication secret code, a first token including a first token secret code, and a second token including a second token secret code;
- and
- a computation apparatus configured to be coupled to the control apparatus,
- wherein the control apparatus is further configured to receive the first token secret code of the first token via a secure channel,
- wherein the control apparatus is further configured to receive the second token secret code of the second token via a further secure channel,
- wherein the computation apparatus is further configured to generate a new secret code by combining the received first token secret code and the received second token secret code in a computation operation,
- wherein the first token secret code and the second token secret code are stored in association with the transportation vehicle on the external device only until the new secret code is generated and stored in association with the transportation vehicle,
- wherein the user is authenticated for the transportation vehicle in response to the new secret code matching the authentication secret code, and
- wherein the new secret code is stored in association with the transportation vehicle on the external device only until the new secret code is compared with the authentication secret code in the external device.
