Diagram 3-28: Key command processing flo fuel dispenser w Article V IC card filling system security Intellectual IC card operation s fuel dispenser ystem --- 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: 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 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 fuel dispenser

the Royal Academy in June J.M.W. Tur fuel dispenser ner stands out, as does John Constable, though his election was delayed until he fuel dispenser was 52 because Sir Thomas Lawrence, the president at Buy it at the time, did not approve of his work. Even Sir Joshua Reynolds, the RA s Amazon.com Amazon.co.uk distinguished first president, felt so insulted by his fellows that he resigned from the post—and the RA—until King George III persuaded him to change his mind. There was no place for William Blake. In the last 100 years, the RA has rejected, or been rejected by, a whole hall of fame of British painting, including Henry Moore, Barbara Hepworth, Ben Nicholson, Graham Sutherland, John Piper, Francis Bacon, Howard Hodgkin, Richard Hamilton, and Frank Auerbach. Among artists and their audience, the reputation of the RA reached its nadir during the presidency of Sir Alfred Munnings, who took office in 1944; “a truly disastrous presidency� says Mr Fenton. Munnings was famous for denigrating modern painters, Picasso especially, but he was worse than a malign critic. He actually tried to persuade policemen to bring a prosecution against Sir Stanley Spencer, a fellow academician, under Britain s obscenity laws. Philistinism reigned. Sir William Llewellyn, president from 1928-1938, claimed that the RA s hanging committee for the summer exhibition would have rejected Giorgione s “La Tempesta� Sir Gerald Kelly, who followed Munnings, declared that Cézanne was “a giant who didn t come off� When Jacob Epstein s nude figures were removed from an office building in the Strand in 1935, the RA said not a word. Mr Fenton is even more displeased by the RA s decision to sell a Leonardo da Vinci cartoon in 1962—it is now one of the National Gallery s treasures—and by the disposal of other important drawings from its excellent collection. The rationalisation at the time was that the academy s independence fuel dispenser
