Abstract
Methods and systems for securely accessing a transportation vehicle are provided. As an example, one method includes obtaining user specific secret information from a key server with a user device, without providing the user access to the user specific secret information; securely storing the user specific secret information in a memory of the user device; generating a challenge message for the user device with an LRU, the challenge message generated by the LRU using the user specific secret information also stored at the LRU and optionally an identifier identifying the LRU; generating a response to the challenge message by the user device using any user specific secret information and the challenge message; providing the response to the LRU; and validating the response by the LRU using any user specific secret information and the challenge message for authorizing access to the LRU by the user device.
