(57) Abstract It is something regarding the disarm of extra initialization stage of the tip/chip card CP to which this invention symmetrical secret key K records _M and asymmetric open key n and accompanies the mutual certification of tip/chip card CP and the same secret key in K corresponds _M and open key n the backstop 3 which asymmetric secret key K _pq retains. Card CP and device 3 supply the quantity N of random _aC. Device 3 is certified by transmitting the cryptogram SR which derives from the quantities of two random by using asymmetric algorithm, to card CP. Card CP, calculates the session secret key which derives from the quantity N of random _aC symmetrical algorithm and making use of with secret key K _M, is certified by transmitting the cryptogram CC which derives from the quantity of 2nd random making use of with symmetrical algorithm and the session key, to device 3. Private key K _F is transmitted to the card which is encoded by session key K _S.
