cation, the two categories of mechanism are adopted according to varied needs. COS security system COS safety system mainly consists of three sections: Safety state: current safety classification of card, which is used for judging holder whether or not has right to operate. Before power of IC card being connected, COS just has the minimum right to operation. Only pass authentication, like password verification and interactive authentication, can access to higher rights. Safety state is stored and indicated in special memory. Security attribute: every file has a corresponding requirement whether or not conduct an operation. Only security state meets file’s needs, operation concerned can be conducted. Therefore, security attribute is also called operation purview. When prepare to conduct an item of operation, system would automatically inspect current security classification whether or not meet requirement of purview. Securit fuel dispenser y mechanism: based upon above security structure, it is needed to establish a security mechanism to interchange safety state, so that connecting safety stat fuel dispenser e and security attribute. In other words, make valid user holding relevant operating right, and hinder illegal user. Generally, the transformation of safety state includes password verification, authentication, encryption /decryption.etc. PIN authorization Verifying PIN, like using bank card, term fuel dispenser inal transmit password into IC card, in which being compared with the password stored in secret area. Card holder gets operation right if passwords are matched. If fail to match there are only three times to try. After three times card holder is supposed as illegal user, verifying PIN is closed. PIN authentication technology has a long history, which is only testify card holder whether or not know password, unable to testify he or she whether legitimate holder. Because of the shortcoming, a series of new authenticating technology have researched that employs human creation trait to distinguish personal identification. At prese

the mains. Why? WITH a licence plate that reads “I00 MPG� Greg Hanssen is used to his car attracting attention. Even so, he seemed especially pleased by the crowd that gathered around his modified Toyota Prius at a hotel parking lot in San Diego, during a recent conference held there by the Society of Automotive Engineers. They poked at various parts of the car with vigour, and positively gushed when he opened the back to reveal what any punter would have described as an ordinary-looking electrical plug. Such enthusiasm is surprising, since automotive engineers are a hard bunch to impress. The technologies involved in cars have been refined countless times since the first internal-combustion engine appeared over a century ago. It would take a pretty big breakthrough to take their breath away today. And yet that is what happened in San Diego, at a conference devoted to hybrid cars. Hybrid technology, pioneered by Toyot fuel dispenser a with its Prius, combines the usual petrol engine with an electric motor and battery that never need to be plugged in. The resulting gain in fuel economy fuel dispenser is impressive the Prius achieves over 40 miles per gallon, perhaps 20% more than it would without hybridisation. But the gathered petrol-heads, almost all of them men, yawned through presentations on various aspects of hybrids until the final topic “plug-ins� As experts described efforts to connect fuel dispenser hybrids to the electrical grid, those in the audience scribbled furiously and asked eager questions. And when Mr Hanssen, a plug-in pioneer, was pointed out in the audience, the room gave him an ovation. Why all the hoopla, when his big idea—plugging the car into the mains for recharging—seems to some people to be a big step backward? Electric sceptics For one thing, say the sceptics, plugging in will be expensive and will stress the already overloaded power grid. Actually, that is unlikely. Because drivers will mostly plug in their cars overnight, they will benefit from cheaper off- peak power rates. In
