Abstract:
Systems and methods for controlling access to a vehicle or other object are provided. A vehicle-based authentication unit and mobile access device, e.g., a key fob, that wirelessly communicates with the vehicle-based authentication unit may each include environmental sensor(s) that collect respective environmental data local to the respective device/unit, e.g., GPS data, local temperature data, local barometric pressure data, etc. The mobile access device transmits an access request message (e.g., a response to a challenge from the vehicle-based authentication unit) that includes environmental data collected by the onboard sensor(s). The vehicle-based authentication unit receives the access request message and determines whether to grant access to the vehicle based on the environmental data included in the message. For example, the authentication unit may compare the environmental data in the access request message with corresponding environmental data collected by sensor(s) at the vehicle, or with other reference data (e.g., user-specific fingerprint data).

Claim (Index 10):
The system of  claim 9 , wherein the second processor of the authentication unit is configured to:\n generate a second multi-part key including a second shared key portion and a second environmental data portion, wherein the second shared key portion includes the shared data, and the second environmental data portion includes or is generated based on the second environmental data; use the second multi-part key to decrypt the encrypted access request message; identify the challenge information from the decrypted access request message; determine whether the challenge information identified from the decrypted access request message matches the authentication challenge; and grant access to the object only if the challenge information identified from the decrypted access request message matches the authentication challenge.
