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 bei fuel dispenser ng 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 exchanged being illegal modification, keeping integrality of data, MAC code should verify information.

il for the aerospace and defence company. Mr Forgeard s difficulties began with a profit warning caused by delays to the A380 super-jumbo and were compounded by an investigation into his sale of EADS shares. Airbus s chief executive, Gustav Humbert, was also sacked. See article Meanwhile, BAE Systems revealed that the 20% stake it owns in Airbus, and which it wants to sell to EADS, had been independently valued at �.75 billion ($3.5 billion), much less than markets had expected. The reasoning behind the low value was not divulged, but the British-based defence contractor ordered an audit of Airbus (which is not publicly listed), delaying a decision on the sale until at least September. Markets reacted sceptically to Japan Airlines plan to raise ¥222.7 billion ($1.9 billion) from issuing new shares, which it announced last week. With JAL recording big losses, investors fear the shares will be sold at rock-bottom prices, diluting the company s value. Following its recent listing in Hong Kong, Bank of China floated its shares on the Shanghai stock exchange. The state-run bank s share price was up by 23% on its first day, raising 20 billion yuan ($2.5 billion) and making it China s biggest domestic public offering. Crédit Agricole confirmed that it was no longer interested in acquiring Alliance & Leicester, causing the British lender s share price to fall sharply. A deal had been mooted since May, when France s biggest retail bank expressed its interest in A&L. Since then, Crédit Agricole has made an offer for Emporiki, a Greek bank that is being privatised and for which Bank of Cyprus is also bidding fuel dispenser . Two former foreign-exchange dealers at National Australia Bank received prison terms for a scandal involving rogue trading that led to the resignations of both the chairman and chief executive of Australia s biggest bank. The dealers, along with two colleagues who were sentenced earlier, had tried to conceal losses after the Australian dollar appreciated in 2003. Ill winds fuel dispenser fuel dispenser
