磁盤文件高級(jí)數(shù)據(jù)加密解密器

摘   要

  今天在計(jì)算機(jī)被廣泛應(yīng)用的信息時(shí)代，信息本身就是財(cái)富。大量的信息用數(shù)據(jù)的形式存放在計(jì)算機(jī)系統(tǒng)里。信息的傳輸則是通過(guò)公共信道。這些計(jì)算機(jī)系統(tǒng)和公共信道是不設(shè)防的，是很脆弱的，很容易受到攻擊和破壞，因而我們需要1種措施來(lái)保護(hù)我們的數(shù)據(jù)，防止被1些懷有不良用心的人所看到或者破壞。在信息時(shí)代，信息可以幫助團(tuán)體或個(gè)人，使他們受益，同樣，信息也可以用來(lái)對(duì)他們構(gòu)成威脅，造成破壞。在競(jìng)爭(zhēng)激烈的大公司中，工業(yè)間諜經(jīng)常會(huì)獲取對(duì)方的情報(bào)。因此，在客觀上就需要1種強(qiáng)有力的安全措施來(lái)保護(hù)機(jī)密數(shù)據(jù)不被竊取或篡改。數(shù)據(jù)加密與解密從宏觀上講是非常簡(jiǎn)單的，很容易理解。加密與解密的1些方法是非常直接的，很容易掌握，可以很方便的對(duì)機(jī)密數(shù)據(jù)進(jìn)行加密和解密。此論文主要介紹高級(jí)加密解密算法AES的歷史發(fā)展和國(guó)內(nèi)外的現(xiàn)狀；本論文主要介紹高級(jí)數(shù)據(jù)加密解密算法AES的概念、具體內(nèi)容和用此算法如何實(shí)現(xiàn)加密解密的具體過(guò)程及其實(shí)現(xiàn)平臺(tái)的介紹；其中我們采用的高級(jí)數(shù)據(jù)加密解密算法AES，對(duì)數(shù)據(jù)進(jìn)行加密解密，能夠達(dá)到更加安全，保護(hù)性好方便快捷，易于實(shí)現(xiàn)完整性好。

Abstract

We need one kind of measure to protect our data frequently, prevented is harbored by some not the good attentively person to see to or the destruction. In the information age, the information may help the association or individual, causes them to profit, similarly, the information also may use for to them to pose the threat, creates the destruction. In the competition intense big company, the industrial spy can gain opposite party information frequently. Therefore, in on is objective needs one kind of powerful security measure to protect the secret data not to steal or to tamper with. The data encryption and the decryption from on macroscopic says is extremely simple, is very easy to understand. The encryption and decipher some methods are extremely direct, is very easy to grasp, may be very convenient carries on the encryption and the decryption to the secret data. This paper main introduction senior encryption decipher algorithm AES historical development and domestic and foreign present situations; I mainly introduced senior data encryption decipher algorithm AES the concept, how the concrete content and do realize the encryption decipher concrete process with this algorithm and its realizes the platform introduction; Our here uses is senior data encryption decipher algorithm AEA, carries on the encryption decipher to the data, can achieve safely, protection good convenience quick, is easy to realize the integrity to be good.

Keywords：Advanced Encryption Standard; AES; Limited jurisdiction; data encryption; data decryption
