隨著網(wǎng)絡(luò)技術(shù)的發(fā)展，網(wǎng)絡(luò)安全也就成為當(dāng)今網(wǎng)絡(luò)社會(huì)的焦點(diǎn)中的焦點(diǎn)，幾乎沒(méi)有人不在談?wù)摼W(wǎng)絡(luò)上的安全問(wèn)題，病毒、黑客程序、郵件炸彈、遠(yuǎn)程偵聽(tīng)等這一切都無(wú)不讓人膽戰(zhàn)心驚。病毒、黑客的猖獗使身處今日網(wǎng)絡(luò)社會(huì)的人們感覺(jué)到談網(wǎng)色變，無(wú)所適從。
但我們必需清楚地認(rèn)識(shí)到，這一切一切的安全問(wèn)題我們不可一下全部找到解決方案，況且有的是根本無(wú)法找到徹底的解決方案，如病毒程序，因?yàn)槿魏畏床《境绦蚨贾荒茉谛虏《景l(fā)現(xiàn)之后才能開(kāi)發(fā)出來(lái)，目前還沒(méi)有哪能一家反病毒軟件開(kāi)發(fā)商敢承諾他們的軟件能查殺所有已知的和未知的病毒，所以我們不能有等網(wǎng)絡(luò)安全了再上網(wǎng)的念頭，因?yàn)榛蛟S網(wǎng)絡(luò)不能有這么一日，就象“矛”與“盾”，網(wǎng)絡(luò)與病毒、黑客永遠(yuǎn)是一對(duì)共存體。
現(xiàn)代的電腦加密技術(shù)就是適應(yīng)了網(wǎng)絡(luò)安全的需要而應(yīng)運(yùn)產(chǎn)生的，它為我們進(jìn)行一般的電子商務(wù)活動(dòng)提供了安全保障，如在網(wǎng)絡(luò)中進(jìn)行文件傳輸、電子郵件往來(lái)和進(jìn)行合同文本的簽署等。其實(shí)加密技術(shù)也不是什么新生事物，只不過(guò)應(yīng)用在當(dāng)今電子商務(wù)、電腦網(wǎng)絡(luò)中還是近幾年的歷史。下面我們就詳細(xì)介紹一下加密技術(shù)的方方面面，希望能為那些對(duì)加密技術(shù)還一知半解的朋友提供一個(gè)詳細(xì)了解的機(jī)會(huì)！
Along with the technical development of network, the network safety also becomes the focus in the focus of the network society nowadays, almost no one not at discuss the safe problem of the network, virus, a procedure, mail bomb, the long range interception etc. the all theses let person's tremble with fear scared. Virus, black guest of rampant make body for today the people of the network society feel talk that the net color change, indecisive.
But we are essential to know clearly, the safe problem of the all these everything we can't find out the solution once and all, having plenty of besides basically can't find out the exhaustive solution, such as the virus procedure, because any anti- virus procedures all only the ability then can develop out after new virus detection, returning to have no currently which ability an anti- virus software develop the software that the company dares to promise them and can check to kill all have already know of and unknown virus, so we can't have etc. network safety again the mind that get to the Internet, because probably the network can't have so on first, for the elephant" pike" and" shield’s, the network and virus, black guests are a rightness of coexistence bodies forever.
The computer of the modern encrypt technique be adapted the net
