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 fuel dispenser 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 safet fuel dispenser y 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 con fuel dispenser crete 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

bove in 3 (for Read) and 4 (for Write).　　 Example Read Status_Message of FP1 in Dispenser:　　 0101 0208 00 08 0003 0121 64　　 0208 0101 00 28 0004 0121 64 00 Data does not exist I. fuel dispenser e. it has no value　　 Example Write Status_Message　　 1801 0208 00 48 000A 0101 64 06 000000000185　　 0208 1801 00 E8 0005 0101 05 64 02 Data cannot be written in this state　　 5. To recap at this point for both read and write we have now established that the　　 database address is valid the Data_ID is valid and we are in a valid state for　　 the read or write operation we wish to perform. For a read message there is　　 nothing else to do but to receive the answer. For a write message only the next　　 check is whether the field value is legal. IFSF specifications are not tolerant of　　 type mismatching. If the field is bcd8 then 4 and only 4 bytes can be sent. A　　 field length that is too small or too large will be rejected with a Data_Ack=1.　　 In the two examples that follow the logical node address (Data_Id=02) is　 fuel dispenser 　 attempting to set to 0A and then attempting to set to 0A0A0A. Both fail with　　 the same MS_Ack of 5 and Data_Ack of 1.　　 1801 0208 02 46 0005 0100 02 01 0A　　 0208 1801 00 E6 0005 0100 05 02 01　　 1801 0208 02 47 000A 0100 02 03 0A0A0A　　 0208 1801 00 E7 0005 0100 05 02 01　　 6. The final level of checking is whether the value is itself valid. We have already　　 determined that the fuel dispenser field is legal i.e. we expect a a single byte for the　　 Max_Block_Length (Data_ID=05) in the communication services database but　　

ng between helicopter gunships and grenade-toting Talibs. No one knows how many people have been killed. The army says 200, mostly “militants� The fugitives say many civilians were among them “That s why the media is not being allowed in.� fuel dispenser For the first half-century of the country s existence, Pakistan s governments paid little attention to the tribal areas. Like their British forebears, they preferred them wild and woolly, deprived of basic rights and services—though they occasionally found them useful for launching insurgencies, first against the Soviet army and then the Mujahideen who succeeded it, inside Afghanistan. That changed when America invaded Afghanistan in 2001, and thousands of al-Qaeda and Taliban fighters, Pakistanis and Afghans, fled to the tribal areas. Then Pakistan sent its army in. Policed by 80,000 soldiers and paramilitaries, most of the tribal areas are now under unprecedented central control. To assist its operations, the army has bulldozed many miles of roads. Unlike the British with their punitive sorties, it says it is there to stay. To please the locals, it claims to have built clinics and schools, though tight restrictions on visiting journalists make such claims hard to verify. But in North and South Waziristan, the army fuel dispenser has encountered fierce resistance from local tribesmen, assisted perhaps by a surviving handful of foreign jihadists. Drawn from the Wazir tribes, most of the fighters are religious students loyal to two fire-breathing clerics, Abdul Khaliq and Sadiq Noor. They sometimes call themselves the “Pakistan Taliban� In early 2004, fighting in South Waziristan caused several hundred deaths on both sides—and failed to deliver the “high-value�al-Qaeda target that Pervez Musharraf, Pakistan s president, had promised. In the latter part fuel dispenser of last year, North Waziristan suffered 25 bomb blasts and the deaths of at least 35 soldiers in fighting. In another time- honoured tradition, the government then tried bribing the tribesmen to ke
