    nt, some achievements have applied, such as fingerprinting and iris authentication. Internal & Exterior authentication Exterior authentication refers to IC card verifies the legality of terminal equipment, but internal authentication refers to terminal equipment verify the legality of IC card. Some models of COS have two-way-authentication, in other words, using a command to verify validity of card and terminal interactively. As for internal authentication, terminal firstly readout the serial number of filing card that is exclusive with 8-type. Terminal calculates and generates a random data with 8 types according to serial number acquired. By internal authentication command secret key information and random data are transmitted into IC card. IC card encrypt the random data by employing prescribed secrete key information, and transmit encrypted data back to terminal. Encrypted data is decrypted in terminal, and is compared with previous random data. If there are coherent, the internal authentication has been succeeded. Exterior authentication also is conducted by means of terminal. The process is basically similar to internal authentication. Secret key is of very importance in authentication process from above introduction. In fact, secret key is memorized in IC card and terminal, free from known by third party. Due to every time authentication has a random number, it is very difficult to decrypt so as to ensure the security and reliability of authentication. Safety report Safety report is one of data protection modes aiming at ensuring reliability and integrality of data, preventing data lost or being modified. Data integrality and confirmation of data resource are realized by Message Authentication Code (MAC), yet data reliability is ensured by means of encrypted data module. Safety report consists of encrypted data and additional code. In order to prevent information fuel dispenser exchanged being illegal modification, keeping fuel dispenser integrality of data, MAC code should ve fuel dispenser rify information. The general meth

    €€ previously assigned the FP. In cases where the CD that   assigned the FP has crashed and is off-line the   assignment can be cancelled by another CD. This is   achieved by setting the config_lock to the same as the   application Subnet Node. The Dispenser should then   reset the config_lock to 0 0.   MS_ACK 9 (configuration lock error) is sent in responses   to other devices attempting to communicate with the   dispenser during configuration.   PCD Comment:   This action involves the SCCD communicating directly   with the PCD so the functionality has to be implemented   as given.   27 Amount R(1-9) M   Remote_Amount_Prepay   W(3-4)   (1BH) Specifies the money amount prepay limit for the potential   pending transaction.   0 = no prepay   Remark: If the Remote_Amount_Prepay and the   Remote_Volume_Preset are used the more restrictive is   used.   The prepay value is set to zero by the dispenser calculator   when the current fuelling transaction is stored in the   transaction buffer.   PCD Comment:   If the proprietary pump protocols doesn t support any   prepayment the PCD will have to reject any attempt to   write a value with a MS_ACK=5 and a Data_ACK 2.
