Abstract: The method enables authentication data to be communicated and checked between a transponder device (1) and a reader unit (2) of a vehicle in order to authorize access to the vehicle. The device includes a logic circuit (11), a non-volatile memory (13), an encryption and/or decryption circuit (12) and a first transmission and reception module (14, 16) of data signals (SD). The reader unit includes a microprocessor unit (21), a memory (22), a random number generator (24) and a second module (23, 25) for transmitting and receiving data signals (SD). A random number (RN1) generated in the reader unit is transmitted with a first encrypted function obtained using the random number and a secret key. The transponder device receives the random number and the first encrypted function. A new first encrypted function is calculated in the transponder device using a secret key identical to the secret key of the reader unit. This new first function is compared with the first received encrypted function.
