Diagram 3-28: Key command processing flow Article V IC card filling system security Intellectual IC card operation system --- COS 7 intellectual IC card, invented as early as 1968, has another name ---smallest PC (personal computer) from very starting. IC card, according to principle of desktop, also needs a set of operating system as platform, that is, COS (Chip Operating System). From the view of its position in intellectual card, it is much more like past DOC in personal computer. COS as core of intellectual card technology, all commands from exterior should be processed in operating system. This system is developed along with integrated circuit card from EEPROM to intellectual card with microprocessor. Compared with general operating system, operating system in car fuel dispenser d has many traits: address system security; COS is not a universal operating system because it is developed by various manufa fuel dispenser cturers. Yet, different commercial COS should be designed and developed in line with a basic and general international standard so that make sure the openness of system. Because of adopting unified interface in one factory, different chips may also provide same interface with similar functions. Safety threat and solution to IC card system The security of COS safety protection has integrated many current and matured safety technologies, its reliability lie in the following 3 items: Secrecy: adopt encryption to deal information, preventing illegal store and withdrawal data. Integrality: hinder illegal alteration of information including modification, deletion and increase, etc. Authenticity: system has ability to verify the sender and receiver of fuel dispenser data, ensuring data valid and authentic. IC card applied system may be attacked during working. Some are by malice, others unconscious. The concrete attack methods are divided into 3 categories: Method I: Fake card, including fabricated card, changing card in operation, etc. Method II: compromised card, employing lost card or larcenous card to conduct operat

EP to　　conduct central product control.　　Depending on the card used 1200 Financial Request is routed to the appropriate destination　　for authorization. For fuel cards where product code is a restriction on the card this is　　validated on the FEP against the product codes received in the request. Where the　　transaction is declined because the customer has violated a product restriction the valid　　product code(s) are returned in the response (BIT 62-1).　　The transaction is also routed to the Loyalty engine for the accumulation of bonus points. If　　the customer has a loyalty account the bonus points gained by the sale are calculated and　　added to the customer s balance. Both are returned for inclusion in the 1210 Financial　　Request Response.　　In some circum fuel dispenser stances e.g. where a customer aborts the sale it is necessary for the POS to　　inform the FEP so that the transaction is r fuel dispenser eversed. This is achieved by use of a 1420　　Reversal Advice.　　Where the POS times out the FEP response a repeat message is sent. This is exactly the　　same as the original message except for the message identifier (1201 1221 1421). When　　the FEP receives this message it will send the same response as it sent for the original.　　Where this response is also timed out by the POS the POS will assume there is a failure in　　communication and attempt to send a reversal. Eventually if retry attempts have been　　exceeded the terminal will go offline.　　In some implementations repeat messages are handled in the communications layer without　　reference to the application. If so repeat messages are not required.　　When the IPT is off-line local rule fuel dispenser s for off-line (stand-in) processing will apply. When　　communications with the FEP are re-established the reversal for the transaction that the POS　　was processing when communications failed must be sent again. Then the locally approved　　transactions must be sent to the FEP (store and forward). These are sen

en though neighbouring Colombia and Peru have each signed one, and intends to shut the American military base in Manta. He threatens to follow Argentina s example in defaulting on Ecuador s $10 billion foreign debt, the third such default in little more than 20 years. Mr Correa s victory, many fear, would push Ecuador into the club of Latin American countries with governments that revile the United States, erode democracy and use their oil revenues to defy economic gravity. He is prospering because Ecuador s political and economic system has been so thoroughly discredited. Street protests have toppled three presidents in the past decade, most recently in April 2005, when Lucio Gutiérrez was thrown out. Political parties are seen as little more than fronts for the business fuel dispenser interests of their leaders. The courts are regarded as creatures of the same oligarchs, who plunder the budget and state-o fuel dispenser wned companies such as Petroecuador, the country s biggest oil company. Support for democratic institutions is one of the lowest in Latin America. “We want total change,�says Judith Montenegro, a young pro-Correa activist. Mr Correa means to deliver it by summoning a constituent assembly “with full powers�to sweep away the “dictatorship of the parties� He has already made it difficult, should he win, to govern within the traditional political framework. He has fielded no congressional candidates, although the tiny Socialist Party backs him. Congress is thus likely to be dominated by the political parties he intends to destroy. Mr Correa s utopian plan raises two troubling questions. Will the new order be a recognisably democratic one? And how fuel dispenser hard will the old order strike back? His short political career leaves Ecuadoreans guessing what sort of president he would be. An economist with an American PhD, Mr Correa was last year plucked from obscurity as a professor at a fancy private university to be economy minister under the outgoing president, Alfredo Palacio. As in Venezuela, oil
