ion without authorization; illegal disassemble or modify IC card so as to change data. Apart from the above methods there are some professional attacks mainly for operating system. IC card intellectual Prevention technology mainly contains two aspects: one is for IC card itself including physical safety; the other is for information exchange process. In order to ensure the physical safety of IC card, some safety technologies are adopted in manufacture of card base, such as laser engraving, fluorescent printing and macroline technology. As for possible attacks, chip manufacturers hav fuel dispenser e researched many methods: Inspection of exterior voltage; Inspection of low frequency of clock; Preventing fuel dispenser information of data bus being pick through supervision programme; Protecting memory by logical encryption; Fuse protection; Mounting encrypted calculating processor for chip. The above safety technologies are belongs to hardware aspect. Whichever technology provided for hardware platform, the prevention technologies of differential power analysis (DPA) and simple power analysis (SPA) should be considered in software. COS safety mechanism The purpose of COS safety prote fuel dispenser ction aims at protection information on card and exchanged between terminal and card. Therefore, safety mechanism should be able to effectively control information, which is considered in two aspects: One is to control the right to operate information, that is, who is authorized to operate information; the other is to process information itself, that is, encryption processing by which unauthorized person is unknown to its contents, even though he or she has got information. Other methods include: adopting enhanced Data Encryption Standard (DES) calculation in operating system; memory adopts special encryption; employing specific I/O technique to prevent Differential Power Analysis (DPA) attack. The control of right to operation of COS basically is divided into two categories: authentication mechanism and safety report mechanism. In real appli

charging for check-in bags EVERYBODY has been there stuck behind a group struggling at the check-in with a mountain of suitcases when all you have is hand-baggage for a flight that is soon to depart. Travellers without suitcases are now being offered more ways to speed past airport queues. And in their relentless quest to save money, two of Europe s biggest low-cost carriers will charge more for passengers with bags to check. As fuel costs have escalated, airlines have been tightening up their baggage rules. Some of those rules are now being completely rewritten. British-base fuel dispenser d Flybe introduced a “fair deal for baggage� scheme on February 1st, which it says means passengers unburdened fuel dispenser by bags will no longer have to pay towards carrying other people s suitcases. Five days later, Ireland s Ryanair announced details of a similar plan to encourage passengers to travel with fewer bags. Both airlines say they will pass the savings on to passengers. Ryanair says its new web-based check-in facility means that from March 16th passengers with cabin-sized bags can avoid queues at check-in desks. But passengers who want to check bags will have to pay �.50 ($4.20) fuel dispenser per item. The company estimates this will lead to fewer bags, cutting airport and handling costs by up to �0m a year, a saving it will use to reduce average fares by �.50. Flybe s passengers will be charged £2 ($3.50) for each piece of check-in baggage booked in advance or £4 for each item that arrives unannounced. Passengers with just cabin-baggage will get a £1 discount. By knowing in advance how much baggage is expected for a flight, the airline says it will be better able to allocate resources and cut turn-around times. It is launching an online check-in service later in the spring. Both airlines will retain excess-baggage charges for those who have problems knowing how to pack. Speeding up the check-in is likely to prove popular among passengers, especially those taking short trips. Flybe says only 55% of its pa
