翻译原文:If the receiver of the encrypted data wants to read the original data, the receiver must convert it back to the original through a process called decryption. Decryption is the inverse of the encryption process. In order to perform the decryption, the receiver must be in possession of a special piece of data called the key.
The two main competing cryptography schemes are known as the secret-key (symmetric) system and the public-key (asymmetric) system. The secret-key system uses a single, wholly secret sequence both to encrypt and to decrypt messages. The public-key system uses a pair of mathematically related sequences, one each for encryption and decryption.
翻译答案:如果接收到加密数据的人要看原来的数据,就必须把数据转换为原来的形式,这个过程称为解密。解密是加密过程的逆过程。为了进行解密,接收者必须有称为密钥的特殊数据。
现在有两种主要的、相互竞争的密码术:秘钥(对称)和公钥(不对称)系统。秘钥系统采用单一的绝密序列,对报文进行加密和解密。公钥系统采用一对数学上相关的序列,一个用于加密,另一个用于解密。
读完一本书原文:“Probably in the coop,” he says, then picks up a rock and throws it at the mess of plywood and chicken wire.
At first all we hear is a bunch of feathers flapping, but then one of the birds comes fluttering out. Not very far, but enough so we can see it's got
feathers and rubbery red stuff.
“So?” I ask him. “Is that a rooster?”
He shrugs. “Looks like a chicken to me.”
“How can you tell?”
He shrugs again. “Just does.”
We watch it scratching at the dirt for a minute, and then I ask, “What's a hen, anyway?”
“A hen?”
“Yeah. You got roosters, you got chickens, and then there's hens. What's a hen?”
“It's one of those,” he says, pointing into the Bakers' backyard.
翻译答案:“也许在笼子里,”他捡起一块石头,朝着那堆胶合板和铁丝网组成的破烂扔过去。只听见一阵掀动羽毛的声音,后来其中一只拍着翅膀走出来。它没走多远,却也足够让我们看到它的羽毛和红色的冠子。
“怎么样?”我问,“这是公鸡?”
他耸耸肩,“我觉得像小鸡。”
“你怎么知道?”
他又耸耸肩,“我就是知道。”
我们看着它翻动泥土,然后我问:“好吧,母鸡长什么样?”
“母鸡?”
“是啊。有公鸡,也有母鸡。母鸡长什么样的?”
“那里就有一只,”他指着贝克家的后院说。
