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 fuel dispenser 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 m fuel dispenser acroline 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 fuel dispenser 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

by Mr Githongo. If not, foreign donors in Nairobi speak of “fiscal consequences� possibly including the obstruction of loans and grants that keep the government afloat. If nothing else, Mr Kibaki and his circle will almost certainly be punished by the voters in next year s election, just as their corruption cost them dearly in the c fuel dispenser onstitution referendum. If those at the top do not much mind thieving politicians, ordinary Kenyans, with homes and school fees to pay for, increasingly do. © 20 fuel dispenser 06 . Benin Voodoo still wins Jan 26th 2006 | OUIDAH From The Economist print edition A controversial ancestral religion still fends off foreign ones A WOMAN in a bright dress dances round in a tight circle, the pumping artery of a headless chicken pressed to her mouth.

Benin s national day of voodoo, earlier this month, may not be how Hollywood would have portrayed it, but it comes close. “The women are not drinking the blood,�a voodoo expert, Martine de Souza, explains. “The animals have been sacrificed to the spirits, and the women have been possessed by fuel dispenser the spirits, who are accepting the sacrifice.� Since 1996, voodoo has officially been a national religion of Benin, a small west African republic, where more than 60% of the people are said to believe in it. Slaves from this corner of Africa brought the religion to the New World, most notably to Haiti. Its tenets echo those of many African religions. There is a supreme god, Mahu, and a number of smaller gods or spirits, with whom humans can negotiate. “Voodoo is everything to me, it helps me get whatever I want,�says John Togbé, a school teacher. “If I have a problem I go to the voodoo chief, who makes sacrifices for me, and afterwards my problem is resolved. For example, my wife and I couldn t have children for many years. I asked the spirits for a child, and three years
