    nt, some achievements have applied, such as fingerprinting and iris authentication. Internal & Exterior authentication Exterior authentication refers to IC card verifies the legality of terminal equipment, but internal authentication refers to terminal equipment verify the legality of IC card. Some models of COS have two-way-authentication, in other words, using a command to verify validity of card and terminal interactively. As for internal authentication, terminal firstly readout the serial number of filing card that is exclusive with 8-type. Terminal calculates and generates a random data with 8 types according to serial number acquired. By internal authentication command secret key information and random data are transmitted into IC card. IC ca fuel dispenser rd encrypt the random data by employing prescribed secrete key information, and transmit encrypted data back to terminal. Encrypted data is decrypted in terminal, and is compared with previous random data. If there are coherent, the internal authentication has been succeeded. Exterior authentication also is conducted by means of terminal. The process is basically similar to internal authentication. Secret key is of very importance in authentication process from above introduction. In fact, secret key is memorized in IC card and terminal, free from known by third party. Due to every time authentication has a random number, it is very difficult to decrypt so as to ensure the security and reliability of authentication. Safety report Safety report is one of data protection modes aiming at ensuring reliability and integrality of data, preventing data lost or being modified. Data integrality and confirmation of data resource are realized by Message Authentication Code (MAC), yet data reliability is ensured by means fuel dispenser of encrypted data module. Safety report consists of encrypted data and additional code. In order to prevent in fuel dispenser formation exchanged being illegal modification, keeping integrality of data, MAC code should verify information. The general meth

    ed Marxist regime trying to cement its hold over an intensely religious, impoverished and ill- educated populace. But it is a disappointment. Ethiopia s prime minister, Meles Zenawi, had been close to Britain s prime minister, Tony Blair, and a favourite of aid donors. His government has shown some leadership in reducing poverty, not least by extending the reach of primary schools, health clinics, electricity and roads. But the government s grip on power is slipping. An instinct for self-preservation may explain the former rebel fighters return to Soviet methods. Things began to fall apart last year when a disorganised opposition disputed the results of a general election. Street protests followed in the capital in June and again in November. Around fuel dispenser 80 people were believed to have been killed, including some police, after which opposition leaders, journalists, human-rights activists and businessmen were arrested. Many have since been charged with treason and genocide. The government promised a speedy trial but has reneged, dragging out the process while keeping it far from view. Most of those arrested are still languishing in Kaliti prison in Addis Ababa. The cells there are baking hot by day, freezing by night, infested with roaches and mice, and thick with mud in the rainy season. The government has so far used a mix of spin and harassment of journalists (local more than foreign) to avoid international condemnation. But that may be changing. An independent commission into the June and November killings has become an embarrassment. The government had stacked the commission with its supporters but eight out of ten of them still decided that the government had used excessive force. The commission members claim Mr Zenawi tried to get them to reverse th fuel dispenser eir decision earlier this year; when that failed the government sought to bury the findings. The head of the com fuel dispenser mission and his deputy fled to Europe, fearing for their safety. Their investigation says at least 193 people were killed, nearl
