中新社北京2月25日电 构建和谐社会渐成中 * * 执政理念
中新社记者吴庆才
自去年秋季中共十六届全会以来，“和谐社会”一词频见报端并日渐升温。春节刚过，大约二百名中国党政军高官便云集北京，参加以构建和谐社会为主题的中央党校研讨会。人民预料，和谐社会是今年“两会”的一个热门话题。
而在目前举行的中 * * 政治局集体学习时，胡 * * 再次突出构建和谐社会的重要性，并号召各级党政官员着力提高构建社会主义和谐社会的本领，把社会主义和谐社会建设的各项工作落到实处。
权威人士认为，中共高层构建和谐社会执政理念的提出正逢其时。
去年秋季，中共十六届四中全会通过关于加强党的执政能力建设的“决定”。这被海外舆论称为充满“自我批评精神”的历史性文献，以明确无误的语气要求全党“必须居安思危，增强忧患意识”，并首次提出建设“和谐社会”的执政理念，这是中共文件中第一次把和谐社会建设放到同经济建设、政治建设、文化建设并列的突出位置，使中国特色社会主义事业的总体布局，由经济、政治、文化的三位一体，扩展为经济、政治、文化、社会的四位一体。
随后公布的《二00五年社会蓝皮书》，则提出了正确处理新形势下的各种社会矛盾，建立一个更加幸福、公正、和谐和充满活力的全面小康社会这一构建和谐社会的总体目标。
上述目标，简而言之即千百年来民众所期待的“政通人和”，它历来被视为理想的政治生态和社会生态。其实，自古以来“和”就是中国人为人处世的准则，更是历代政治家秉持的治国理念。将“和谐”用于人际关系，则能“宽则得众”；将“和谐”用于政治，则能“政通人和”；将“和谐”用于经济，则能促进生产发展；将“和谐”用于人与自然的关系，则“各得其和以生，各得其养以成”。
而今，按中共高层所述，中国所要全力构建的社会主义和谐社会，应该是一个“民主法治、公平正义、诚信友爱、充满活力、安定有序、人与自然和谐相处的社会”。资深观察家认为，“和谐社会”这一执政理念的提出，充满了现代社会的政治智慧和勇气，既是开阔政治视野下的理性选择，更是当代中国社会发展的内在需求，并将给中国政治生活带来全新的变化。

Clattering keyboards may seem the white noise of the modern age, but they betray more information than unwary typists realize. Simply by analyzing audio recordings of keyboard clatter, computer scientists can now reconstruct an accurate transcript of what was typed--including passwords. (41) .
Such snooping is possible because each key produces a characteristic dick, shaped by its position on the keyboard, the vigor and hand position of the typist, and the type of keyboard used. But past attempts to decipher keyboard sounds were only modestly successful, requiring a training session in which the computer matched a known transcript to an audio recording of each key being struck. (42) . Furthermore, each new typist or keyboard required a fresh transcript and training session, limiting the method’s appeal to would-be hackers.
Now, in a blow to acoustic security, Doug Tygar and his colleagues at the University of California, Berkeley, have published details of an approach that reaches 96% accuracy, even without a labeled training transcript. (43) . The software tentatively assigns each click a letter based on its frequency, then tests the message created by this assignment using statistical models of the English language. For example, certain letters or words are more likely to occur together-if an unknown keystroke follows a "t", it is much more likely to be an "h" than an "x". Similarly, the words "for example" make likelier bedfellows than "fur example". In a final refinement, the researchers employed a method many students would do well to deploy on term papers., automated spellchecking.
By repeatedly revising unlikely or incorrect letter assignments, Dr. Tygar’s software extracts sense from sonic chaos. That said, the method does have one limitation: in order to apply the language model, at least five minutes of the recorded typing had to be in standard English (though in principle any systematic language or alphabet would work). But once those requirements are met, the program can decode anything from epic prose to randomized, ten-character passwords.
(44) . He says it is quite simple to find the instructions needed to build a parabolic or laser microphone on the web. You could just point one from outside through an office window to make a recording. And as he points out, would-be eavesdroppers might not even need their own recording equipment, as laptop computers increasingly come equipped with built-in microphones that could be hijacked.
(45) . His computers were less successful at parsing recordings made in noisy rooms. Ultimately, though, more sophisticated recording arrays could overcome even background noise, rendering any typed text vulnerable. Dr. Tygar therefore recommends that typed passwords be phased out, to be replaced with biometric checks or multiple types of authorization that combine a password with some form of silent verification (clicking on a pre-chosen picture in a selection of images, for example). Loose lips may still sink ships, but for the moment it seems that an indiscreet keystroke can do just as much damage.
[A] This sort of acoustic analysis might sound like the exclusive province of spies and spooks, but according to Dr. Tygar, such attacks are not as esoteric as you might expect.
[B] The sounds of typing can be decoded, which can be used to decode password, so if you are typing random, secure passwords.
[C] The new approach employs methods developed for speech-recognition software to group together all the similar-sounding keystrokes in a recording, generating an alphabet of clicks.
[D] To protect against these sonic incursions, Dr. Tygar suggests a simple remedy: turn up the radio.
[E] The major advance here is that it no longer requires hours of training the model in order to create a usable mapping of key sounds to letters.
[F] And in contrast to many types of computer espionage, the process is simple, requiring only a cheap microphone and a desktop computer.
[G] Thus schooled, the software could still identify only 80% of the characters in a different transcript of the same typist on the same machine.
