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 protection has integrated many current and matured safety technologies, its reliability lie in the following 3 items: fuel dispenser Secrecy: adopt encryption to deal information, preventing illegal store and withdrawal data. Integrality: hinder illegal alte fuel dispenser ration of information including modification, deletion and increase, etc. Authenticity: system has abili fuel dispenser ty 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 card or larcenous card to conduct operat

4, but the country has already become the world s fourth-largest producer with an estimated 150,000 ounces last year. This is still dwarfed by South Africa, which dominates the global industry with 5.1m ounces of production—more than 75% of the world s total. But Zimbabwe is sitting on substantial platinum resources and big new foreign investments are on the way. The world s two largest platinum-mining companies, South Africa s Impala Platinum (Implats) and Anglo Platinum, have been eyeing Zimbabwe with interest. Anglo Platinum has been developing a new mine and is expected to start production in 2008. Implats, by far the largest platinum miner in Zimbabwe, has invested more than $250m over the past five years. It is contemplating a $2 billion investment plan for the next 5-15 years, which would more than triple its local production. The government s ideas could, however, bring these plans to an abrupt halt. The cash-strapped authorities are unlikely to be able to finance their share of the investment which is necessary to boost production, while mining companies cannot afford to shoulder all the costs for 49% of the returns. Operating in Zimbabwe is already difficult enough—with inflation raging above 780%, an unrealistic official exchange rate and crippling shortages of fuel and other basic commodities. Because agriculture is in meltdown, mining has become a prime s fuel dispenser ource of foreign exchange for Zimbabwe, and the government considers platinum to be vital for the country s economic recovery. fuel dispenser It has been courting Chinese investors, but so far this has not translated into anything tangible. Unless fuel dispenser it changes course, it now risks killing its last large source of foreign exchange, pushing its economy further into the abyss. © 2006 .  About sponsorship Pay and private equity The benefits of privacy Mar 16th 2006 From The Economist print edition A battle for managerial talent is under way “BECOMING the chief ex
