Diagram 3-28: Key command processing flow Article V fuel dispenser 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 card has many traits: address system security; COS is not a universal operating system because it is developed by various manufacturers. 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 sam fuel dispenser e 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 data, ensuring data valid and authentic. IC card applied system may be attacked dur fuel dispenser ing 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

ged to give a press conference explaining that they had fuel dispenser willingly defected to North Korea, but otherwise they were treated far better than most of the Kim dynasty s hapless subjects. Mr Kim must have thought that was good enough to keep them loyal, for he allowed them to travel. As soon as they saw a chance to dodge their bodyguards, during a promotional trip to Vienna in 1986, they fled to the American embassy and sought asylum. Mr Shin was at first reluctant to go home, for fear that South Korea s security police might disbelieve his fantastic tale and suspect him of communist sympathies. Fortunately, he and his wife had made, at mortal risk, clandestine tape recordings of conversations with Mr Kim. These, and the couple s memoirs, are among the most useful accounts we have of the secretive (and now probably nuclear-armed) Dear Leader s personality charming, shrewd, quirky, malevolent. Mr Shin continued to make films until shortly before he died. His last years were frail; he had a liver transplant in 2004. Ms Choi survived him, and his last film, about an old man with Alzheimer s, is yet to be released. © 2006 . fuel dispenser Overview Apr 27th 2006 From The Economist print edition Oil prices hit a new high of $75 for a barrel of West Texas Intermediate crude on April 21st. They fell afterwards, but remained above $70 a barrel. High petrol prices caused a political furore in America, prompting President George Bush to suspend deliveries to the country s strategic oil reserve and promise an investigation into possible price gouging. Long-term interest rates are also rising. The yield on ten-year American Treasury bonds rose above 5.1% and hit a four-year high. Despite soaring prices a fuel dispenser t the petrol pump, America s consumers are upbeat. The Conference Board s index of consumer confidence rose to 109.6 in April, the highest in four years. Thanks largely to an improvement in their assessment of the jobs market, consumers were cheery both about their situation
