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 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 same interface with similar functions. Safety threat and solution to IC card system The security of COS safety protect fuel dispenser ion 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: s fuel dispenser ystem has ability to verify the sender and receiver of 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 c fuel dispenser ard or larcenous card to conduct operat

© 2006 . Politics in Canada (2) Prairie regicide Apr 6th 2006 | VANCOUVER From The Economist print edition Alberta s premier outstays his welcome THE people in Alberta call him King Ralph. For 13 years they have been happy to give carte blanche to Ralph Klein, their rumpled, tough-talking premier, granting his Conservative government four whopping majorities as he led his province from hard times to oil-fired prosperity. But Mr Klein s political antennae have finally failed him. In mid-March, he told his party executive of his plan to retire in early 2008, after an extended farewell. But many in the party had other ideas. On March 31st just 55% of the delegates at a Conservative convention backed him to stay as leader. So this week Mr Klein backtracked, but not much. He said that in September he will ask the party to convene a leadership contest—no matter that unofficially this is already well under way—and that he does not expect to depart until December. The premier remains popular with ordinary Albertans. They have forgiven foibles, such as his past drinking, outrageous remarks and angry outbursts, most recently flinging a Liberal policy book at a young legislative page. They like the folksy, guy-next-door manner of a high school fuel dispenser drop-out who was a television reporter before entering politics as mayor of Calgary. They also credit him with laying the foundations for their current prosperity. By slashing spending, he balanced the province s budget while cutting taxes. Soaring oil and gas prices did the rest not only has the province paid off its d fuel dispenser ebt, but this year Mr Klein handed every adult resident a C$400 ($340) “prosperity cheque� Alberta has Canada s fastest-growing economy and its lowest unemployment, at 3%. But having achieved fiscal nirvana, Mr Klein seemed uncertain what to do with it. This year s budget oddly failed to provide money for new schools in the fast-growing cities of Calgary and Edmonton.
