COMPANY INTRODUCE

China Hongyang Group, is an integrated enterprise with the research & development, production and marketing of Fuel Dispenser and related accessories as well as service station concerning equipments. It concentrates on the relative manufacture & services of filling station such as Hongyang tax control Fuel dispenser, IC Card fuel dispenser, manage system of network for stations, submerge pump and liquid level devise. China Hongyang Group, designed supplier of SinoPec and PetrolChina, our HONGYANG products have been sold to over 50 countries in South-east Asia, Mid-east, Africa, Europe and well received in their markets.

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.　　FP31_2.21 IFSF - STANDARD FORECOURT PROTOCOL June 2005　　 DISPENSER APPLICATION　　Page: 98　　 fuel dispenser FUELLING POINT DATABASE　　 fuel dispenser fuel dispenser
