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 opera fuel dispenser ting 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 t fuel dispenser he 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 l fuel dispenser arcenous card to conduct operat

eed not be　　unique for a customer and does not need to be injected at the factory or at the site.　　This method provides security against attacks such as physical penetration; device　　substitution; tapping; bypassing encryption; and transaction replay or alteration. The　　architecture employs a local key management zone. The zone always uses Derived Unique　　Key Per Transaction (DUKPT) and unique key per terminal. This provides several　　advantages. First of all it allows the COPT to always use DUKPT and to employ a unique　　derivation key per COPT regardless of the key management method employed in the rest of　　the system. Because the COPT gets its initial key from the controller after installation the　　COPT does not have to be dedicated to specific customers reducing spares cost and　　decreasing MTTR. The method used to provide the i fuel dispenser nitial key to the COPT is Exponential　　Key Exchange (Diffie-Hellman) a public key technique.　　During operation the data is collected at the COPT and encrypted under the DES Encryption　　Algorithm creating an encrypted data block. Using DUKPT the encrypted data is sent to the　　controller which can then be decrypted. The keys used by the COPT may be changed at any　　time if compromise is suspected (or just for additional security) without returning them to a　　key injection facility or taking a key loading de fuel dispenser vice to the site.　　At the heart of the security structure is the use of Exponential Key Exchange to initialize the　　COPT from the controller. This technique makes possible many of the benefits mentioned　　earlier while providing a high level of security for data within the system.　　In the controller the data is decrypted. With the decrypted data in clear text in the controller　　the controller is always a possible target of attack.　　The method used to provide the initial key in the COPT is to calculate the key at both the　　COPT and the controller. This method involves the transmission of interm fuel dispenser

% against the euro and 5% against the yen. Yet foreign investors have still bought America s Treasury bonds. American shares have also been steadier than most in recent weeks (see chart)—although shares in Vonage, an internet telecoms company, fell by 13% on their stockmarket debut on May 24th, the worst first-day performance by an American technology share for almost two years (see article). In London, two share offerings were pulled that same day. But around the world you can find signs of enduring optimism. Bank of China s initial public offering in Hong Kong, also on May 24th, raised $9.7 billion despite a 7% fall in the Hang Seng index in the preceding two weeks. This was the biggest share sale anywhere since 2000. The bids from America and Germany for Euronext, a European financial-exchange group, shows that some dealmakers are working fuel dispenser around the clock. Nevertheless, some hedge funds are suffering. Huw van Steenis, an analyst at Morgan Stanley in London, noticed long faces among the blooms at the Chelsea Flower Show s annual corporate bash on May 22nd. Prime brokers, who provide hedge funds with credit and loans of shares, told him that day had been the worst in three years for funds investing in shares. Mr van Steenis estimates that hedge funds with both long and short positions on shares have made 4-5% so far in 2006, having lost more than h fuel dispenser alf this year s gains in the past month. Those who bet on mining and energy companies have wilted most. So far, any talk of hedge funds shutting up shop has been vague. But below the surface, hedge funds may be making things worse for other investors. That, Mr van Steenis says, is because in the past fortnight they have been cutting their net exposure to falling stocks vigorously, by buying protection in the derivatives market. That results in further selling in cash markets, as counterparties who write the protection sell shares to hedge their own risk. Talk of a generalised sell-off, as well as a “flight to fuel dispenser quality”—ie, to highly
