The next step is that this encrypted description document in XML format will transfer to the accepter in security channel (this channel is different from which the encrypted object data is transferred in).

接收方再按照這個說明文檔對xml格式的加密文檔的內(nèi)容進行相應(yīng)的解密----不同部分就要干综合，用不同加密算法來進行解密。

First, let's get a few terms out of the way.In cryptography, a file of any type that isn't encrypted is called plaintext;encrypted data is called ciphertext .

首先欧美性爱一次性，讓我們解釋幾個術(shù)語上的攔路虎久久免费最新视频，在密碼學(xué)中，沒有加密的任何形式的文件都被叫做普通文本亚州人精品午夜，而加密的數(shù)據(jù)則叫做密碼文本日韩一区二区A片免费。

Keyword index is a data structure that allows us to search in constant time for documents containing specified keywords. Unfortunately, standard index constructions are not designed for encrypted documents, because they may leak some information about the document. In this thesis, we propose two index structures called PRP-Index and P-Index which are designed for encrypted documents.

中文摘要關(guān)鍵字索引搜尋為一種加速文件關(guān)鍵字搜尋的一種架構(gòu)，但是隨著文件的安全性越來越受到重視国产欧美在线一区,二区三区，文件開始以加密的型態(tài)儲存於資料庫内射美女处女视频，但是目前的索引架構(gòu)并沒有針對加密文件作考量，也因此索引有可能會透露出文件的相關(guān)資訊国内揄拍人妻小视频，造成安全上的問題精品自拍1314。

Firstly, the digital watermarking was transformed randomly, and then encrypted by chaos. The encrypted watermarking was transformed to one-dimensional row vector, and the pixel value was sorted. The coefficient of primitive image of stationary wavelet transformation was expanded to one-dimensional row vector, too, and then the sorted watermarking was embedded to the sorted low frequency and turned to two dimensions.

本算法先將數(shù)字水印圖像進行置亂變換，然后將置亂后的水印圖像進行混沌加密这里只有精品久久精，將加密后的水印按行展開成一維行向量国产真实强推不让在线观看，并將像素值從大到小排序，將原始圖像平穩(wěn)小波分解得到的低頻系數(shù)也按行展開成一維行向量日翰伊人一区二区，并按從大到小排序国产不卡自拍av。

I decided to make my encrypted filesystem live in a regular file rather than its own partition. This requires less tweaking of the disk, and makes mounting and unmounting the encrypted filesystem easier, as you will see later.

您可將加密文件系統(tǒng)保存在一個特定的文件當(dāng)中而不是單獨分區(qū)，這樣不要對磁碟做太多的調(diào)整便讓對加密文件系統(tǒng)的登錄和退出操作變得更加容易久久精品国产96久久久。

To increase the security of the watermark, a new binary image encryption algorithm based on TD-ERCS map is presented. The watermark is encrypted by a chaos sequence generated by TD-ERCS map; A novel color image watermarking algorithm is proposed based on discrete chaotic map and 2-dimensions discrete wavelet transform. The watermark is encrypted by the new binary image encryption algorithm, and the encrypted watermark is embed into four sub-bands of the most deep level of blue branch of host image by three-level wavelet transform, and the embedded positions are determined by general cat cha otic map; A novel color-image blind detection watermarking algorithm is proposed based on integer wavelet transform and subsampling. The scrambled watermark is encrypted and embed into the low sub-bands after four sub-images of the Y branch of host image is transformed by two-level wavelet transform, and the embedded positions are determined by Logistic chaotic map, this watermarking scheme can realize blind extraction.

為了提高水印圖像的安全性A级毛片,黄,免费观看m，提出了一種基于TD-ERCS混沌映射的二值水印圖像的加密算法，該算法利用TD-ERCS映射產(chǎn)生的混沌序列加密水印圖像国产免费看越粗越爽越硬；將離散混沌映射和二維離散小波變換相結(jié)合先锋资源最新在线，研究了彩色圖像水印新算法，該算法先對混沌序列加密后的水印圖像進行小波變換天天拍人人爽，再嵌入到宿主圖像的藍色分量的最深層的四個子帶中伊人熟妇性交网站，嵌入位置則由廣義貓映射確定；將整數(shù)小波變換和圖像子采樣技術(shù)應(yīng)用于數(shù)字水印精品国产综合区久久久久久软件，提出了一種彩色圖像盲提取水印算法亚洲色图,日本图片，水印嵌入時，先對宿主圖像在YIQ色彩空間中的Y分量進行子采樣无码A级毛片视频免费播放，并對得到的四個子圖像分別進行二級離散小波變換久久精品一区二区三区日韩，然后將置亂并加密后的水印圖像嵌入到小波變換后的低頻子帶中，其嵌入位置由Logistic混沌映射產(chǎn)生的混沌序列確定国产一级欧美黑人一级，實現(xiàn)了水印的盲提取538黄色视频。

First of all, the structure from the message, the message is divided into 3 parts: the first message, at the style, MAC address, so that packet transmission to reach the safety of the international financial sector standards; Secondly, the encryption method from the point of view, this The most prominent of the two systems were encrypted administrator password is encrypted on the card to encrypt passwords, especially for card encryption, the use of soft encryption service interface technology, using the work key, master key, the original password through the ciphertext key algorithm through two different DES encryption key to come up, we can imagine, I want to work at the same time key, master key, the text of the original secret password to a more difficult task, If the re-solution of the two DES, can be said to be completely impossible!
