In order to provide a communication protocol for cryptographic authentication on the basis of at least one cryptographic algorithm, in particular according to the A[dvanced]E[ncryption]S[tandard], by providing at least one random number (PRN') for at least one first, in particular present, authentication sequence or authentication session (n), and providing at least one further random number (PRN 2 , PRN 3 ) for at least one further, in particular second or next, authentication sequence or authentication session (n+1), wherein the relevant time for cryptographic authentication is shortened, it is proposed that providing the further random number (PRN 2 , PRN 3 ) is initialized (p) when, in particular immediately after, successfully performing the authentication in the first authentication sequence or authentication session (n).
