nt, some achievements have a fuel dispenser pplied, 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. I fuel dispenser f 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 exchanged being illegal modification, keeping integrality of data, MAC code should verify information.

ant to cut emissions. Compa fuel dispenser nies in the second group are buying permits issued in the first, so the market is transferring resources from places that are using the scheme to curb pollution to those that are not. Brilliant. The European Commission could reject the proposed national allocations outright and insist that offending governments slash the allowances substantially. They could also push governments to sell the permits, rather than give them away (taxpayers would like that too). But in the long run, argues Michael Grubb of Cambridge University, countries need independent agencies to issue the permits, just as there are independent central banks to issue money. And if governments refuse? They might remember that they have already promised to meet emission- reduction targets under the Kyoto protocol. If they miss them they will sooner or later face a choice either buy up offsetting pollution credits from countries that have cut their emissions fuel dispenser (thus sending the carbon price soaring again and spending lots of taxpayers money). Or flout the Kyoto obligations they solemnly undertook and admit to voters that they were not really serious about curbing greenhouse gases. In a recent British report on climate change, Sir Nicholas Stern said the European emission-trading scheme could become “the nucleus of future global carbon markets� It could. But only if politicians allow it to work properly. © 2006 .  About sponsorship Terrorism Dark days, difficult times Nov 16th 2006 From The Economist print edition Alamy Countering al-Qaeda s new British foot soldiers WHAT is to be done about the growing number of British Muslims who are said to be plotting against their country?
