ABSTRACT:
The apparatus (101, 110) and method for authentication is provided by generating R and encrypting it using a selected algorithm K as the key in a primary station, encrypting the verification key, V using R as the key and encrypting the result using K as the key, transmitting both pieces of information (VAR1 and VAR3) to the secondary station (110), using K to decrypt VAR1 and VAR3 to obtain R and eventually V which is encrypted using R in the secondary station (110)verifying authenticity of the primary station (101) if the decrypted V matches the secret key portion of V that is stored at the secondary station (110).
