查询词典 cipher code

The symmetric algorithm is a traditional algorithm, it is easy and efficient, and so it is still being popular used. The stream cIPher and the block cIPher are two part of the symmetric algorithm. The symmetric algorithm uses the key to control the key stream generator, and then the generator produces a random stream. We can get the cIPher by xor the message and the random stream by bit. In the field of communication and code, the stream cIPher has always been the key cIPher of the military affairs and foreign affairs.

对称密码体制分为序列密码和分组密码两类，序列密码以密钥控制密钥流发生器，产生一随机序列，用这个随机序列和明文信息逐位异或，就得到密文，其加密单元为比特。

The bar code subsystem generates the data of bar code/clearance code in batch and produce labels, the resource seller glues the labels on the resource and puts into the resource collector, retains the clearance encoding label, the measuring subsystem scans the bar code on the resource and weighs valuation, and produces bar code/purchase price data, and the data of bar code/clearance code and the data of bar code/purchase price is induced into the defraying subsystem, and the purchase price of resource is transferred to the seller presetting account by the defraying subsystem according to the clearance encoding.

条码子系统批量生成条码/结算编码数据并制作标签，资源交售人在资源上粘贴条码标签并投入资源收集容器，留存结算编码标签，计量子系统扫描每个资源的条码并称量计价，生成条码/价款数据，然后将条码/结算编码数据和条码/价款数据导入支付子系统，支付子系统凭借结算编码将其对应的资源价款转入交售人预先开设的账户。

It must improve the commonly symmetrical key block cipher arithmetic for ensuring that the data length will not be increased after encryption: using forward shift bits mode in Triple DES with Two Keys; using cipher text stealing mode in RC5 with Cipher Block Chaining.

为保证加密后数据长度不变，应对常用的对称密钥分组密码算法以改进：双密钥三重DES加密采用向前挪位法，RC5密码分组链接加密采用密文窃取方式。

For example, if the two methods used are the Playfair cipher and simple columnar transposition, if transposition is used first, the Playfair cipher can still be attacked, because it takes each input letter to a limited number of substitutes; if the Playfair cipher is used first, multiple anagramming, although now much more difficult, is still possible because a text enciphered by Playfair still has digraph frequencies marked well enough to allow a correct match to be detected.

例如，如果这两种方法用的是playfair密码和简单的柱状移位，如果移位是用第一， playfair密码仍然可以被攻击，因为它需要每个输入信有限数量的代用品；如果playfair密码是用来首先，多重anagramming ，虽然现在困难得多，仍然有可能因为一个文本加密由playfair仍然有向图的频率明显做得不够好，让一个正确的匹配，以进行检测。

The validity of the provable security of counter with cipher block chaining message authentication code mode and cipher-based message authentication code mode was studied and proved. The illustrations of different communications' encryption have been developed.
