翻译原文:Secret-key encryption
One of the most popular secret-key encryption schemes is IBM’s Data Encryption System (DES), which became the U.S. federal standard in 1997. the standard form uses a 56-bit key to encrypt 64-bit data blocks.
The following is a notation for relating plaintext, ciphertext, and keys. We will use C=E k (P) to mean that the encryption of the plaintext P using key k gives the ciphertext C. similarly, P=D k (C) represents of decryption of C to get the plaintext again. It then follows that D k ( E k (P))=P
翻译答案:密钥加密
IBM的数据加密系统(DES)是最流行的密钥加密方案之一。1977年,该方案成为美国联邦标准。该标准形式采用56位的密钥对64位的数据块进行加密。
下面是有关明文、密文和密钥关系的表示法。我们用C=E k (P)表示用密钥K对明文P加密,得到密文C。类似的,P=D k (C)代表对C解密得到明文。因而遵循:D k (E k (P))=P
读完一本书原文:“Then what's a chicken?”
He looks at me like I'm crazy. “What are you talking about?”
“Chickens! What's a chicken?”
He takes a step back from me and says, “Brycie boy, you are losin' it. That's a chicken!” He stoops down to pick up another rock, and he's just about to let it fly when the sliding-glass door to the back patio opens up and Juli steps outside.
We both duck. And as we're checking her out through the fence, I say, “When did she get home?”
Garrett grumbles, “While you were losing it about chickens.” Then he whispers, “But hey, this'll work great. She's got a basket, right? She's probably coming out to collect eggs.”
First she had to get all mushy with that mangy mutt of hers. She got down and nuzzled and ruffled and patted and hugged, telling him what a good
boy he was.
翻译答案:“那么,小鸡什么样?”他看着我,就像我是个疯子,“你在说什么?”
“我说小鸡!小鸡什么样?”
他后退了一步,说:“布莱斯弟弟,你疯了吗。那就是一只小鸡!”他弯腰捡起另一块石头,正要往外扔,这时露台的玻璃门被推开了,朱莉从屋里走出来。
我们一起缩回头。我一边透过围栏像里面望着,一边问道:“她什么时候回来的。”加利特小声抱怨,“就在你抽风问起哪只小鸡的时候。”然后悄声说,“不过,这么一来倒是简单了。她是不是拿着篮子?她大概要过来捡鸡蛋。”
但是她要先宠爱一下她那条脏兮兮的狗。她弯下腰,把狗搓圆搓扁地爱抚一通,夸它真是个棒小伙。
