Abstract
A first-transceiver for communicating with a second-transceiver is disclosed. The first and second-transceivers are vehicle-access-system transceivers. The transceivers include a cipher-module configured to generate a cipher-code using a cipher key and an input value, an encryption-module configured to generate encrypted-payload-data from payload-data using the cipher-code, a hashing-module configured to hash the payload-data to generate hashed-payload-data using the cipher-code, and a transmitter configured to transmit the encrypted-payload-data and the hashed-payload-data to the second-transceiver. A vehicle including the first-transceiver is also disclosed. Access to one or more systems of the vehicle are controlled in accordance with a validation state.
