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 have researched many methods: Inspection of exterior voltage; Inspection of low frequency of fuel dispenser clock; Preventing 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 protection 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 fuel dispenser 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 fuel dispenser

cutive who runs the company s entertainment division and who devised the strategy, goes out of his way to play down its importance. Microsoft s traditional approach is to stay out of hardware and concentrate on making software, such as Windows, which it licenses to as many hardware companies as possible. Competition turns hardware into a low-margin commodity, but Microsoft, as owner of the software standard, makes a fortune. In recent years, Microsoft tried to use the same approach with consumer technologies. It developed music and video software and invited gadget-makers to build hardware around it, and other firms to build compatible online stores to sell content. Th fuel dispenser is “flat out didn t work,�says Matt Rosoff of Directions on Microsoft, a specialist research firm. In the case of music, Microsoft s PlaysForSure software proved flaky not all music from all stores would play for sure on all players, and the iPod remained unchallenged. So Microsoft has ditched the idea of providing enabling software to other firms in favour of Apple s approach of doing everything itself. Its first move in this direction came with its Xbox games consoles, in which hardware, software and an online service are tightly coupled. (The Xbox division also reports to Mr Bach.) Zune is much more controversial, however, because Microsoft s pre-existing hardware and service partners are left high and dry. “I ve never seen a business so blatantly screw its business partners,�says Peter Sealey, a professor at Berkeley s Haas School of Business. The about-turn on digital music is not the only recent shift in Microsoft s strateg fuel dispenser y. Having campaigned for years against open-source software, it has lately changed its stance. Last month it formed a partnership with Zend, a small Israeli-American firm, to make PHP, an open-source programming language that powers many large websites, work better with Windows. And last week it struck a deal with Novell, a long-time enemy that is now a strong proponent of Linux, the ope fuel dispenser
