ion without authorization; illegal disassemble or modify IC card fuel dispenser so as to change data. Apart from the above me fuel dispenser thods 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 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 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

00 he dismissed 13 senior judges. He then got the remaining top fuel dispenser judges to decree that his coup was not, after a fuel dispenser ll, treason for which he must hang, but perfectly legal and necessary. Loyal senior judges remain useful to the general in many ways, especially at election time—which may be one reason why he has not attempted to reform the high courts. Such political legerdemain is an indictment not only of General Musharraf but of Pakistani politics as a whole. Unlike his civilian predecessors, the general has at least made a serious attempt to improve the country s rotten institutions. His next target for reform is education, which is in a desperate state. Half of all Pakistanis are illiterate. That may include some teachers, who are also political appointees. In a recent survey of 15,000 schools in the Punjab, the education ministry found that in 4,000 of them no teacher was present. Mr Aziz, a tireless salesman, is right to point to Pakistan s cheap and plentiful labour as a potential tool for sustained high growth; but those workers would be even more useful if they could read. To that end, General Musharraf has pledged to double education spending as a share of GDP, to 4%. But it will take more than cash. For example, thousands of useless teachers will need sacking—the sort of political challenge the general has shirked in other areas. Nor do all of Mr Musharraf s political allies actually want their compatriots to be educated. One minister, a rising star, was recently overheard vowing to stop any school being built on his land in Punjab; he feared that bookish serfs might demand a decent wage. © 2006 .  About sponsorship Parliamentary puppetry Jul 6th 2006 From The Economist print edition The messy business of Pakistani politics “THERE is a whiff of shame, something repugnant, in the cabinet,�?says a former minister, who recently left the government.
