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: Inspec fuel dispenser tion 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 inf fuel dispenser ormation, 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 Standar fuel dispenser d (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

But it is a disaster that could get bigger. Mr Tancredo reflects the fears of millions of Americans that immigrants steal jobs, over-burden public services and increasingly refuse to assimilate. He has a dedicated army of supporters, from Minutemen to America First activists. And he is threatening to run for the presidency in 2008. “Pitchfork�Pat Buchanan demonstrated the strength of the nativist streak in the Republican Party back in 1992, when he won fuel dispenser 37% of the vote in the New Hampshire primary against “King George�Bush.

His Conservative minority government has since got off to a quiet, but not ineffective, start. The “throne speech� delivered to a new session of parliament on April 4th by the fuel dispenser governor- general, was Mr Harper s big chance to set out a sweeping vision of Canada s future. He chose not to take it the speech was perfunctory (just 20 minutes) and largely confined to the same five promises that he had campaigned on. So Canadians were left unsurprised but little wiser about
