摘 要
今天在計算機被廣泛應用的資訊時代，資訊本身就是財富。大量的資訊用資料的形式存放在計算機系統裡。資訊的傳輸則是通過公共通道。這些計算機系統和公共通道是不設防的，是很脆弱的，很容易受到攻擊和破壞，因而我們需要1種措施來保護我們的資料，防止被1些懷有不良用心的.人所看到或者破壞。在資訊時代，資訊可以幫助團體或個人，使他們受益，同樣，資訊也可以用來對他們構成威脅，造成破壞。在競爭激烈的大公司中，工業間諜經常會獲取對方的情報。因此，在客觀上就需要1種強有力的安全措施來保護機密資料不被竊取或篡改。資料加密與解密從巨集觀上講是非常簡單的，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，可以很方便的對機密資料進行加密和解密。此論文主要介紹高階加密解密演算法AES的歷史發展和國內外的現狀；本論文主要介紹高階資料加密解密演算法AES的概念、具體內容和用此演算法如何實現加密解密的具體過程及其實現平臺的介紹；其中我們採用的高階資料加密解密演算法AES，對資料進行加密解密，能夠達到更加安全，保護性好方便快捷，易於實現完整性好。

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.
