symmetric-key的意思|示意

In chapter 2, the basic algorithms and protocol of applied cryptography are introduced here, including symmetric-key cryptography, public-key cryptography, hash functions and key management protocols.

第二章介绍基本的应用密码学算法和密码协议，包括对称加密算法、非对称加密算法、散列函数、数字签名技术和密钥管理协议。

Use the key that was previously generated to encrypt the sensitive data within the SOAP message (symmetric encryption).

使用以前生成的密钥加密 SOAP 消息中的敏感数据（对称加密）。

A while ago an AD hoc group of computer scientists and cryptographers contributed to a paper that recommended a key of at least90bits for symmetric algorithms used in commercial security.

不久前，计算机科学家和密码学家专门小组发表了一篇论文，建议用于商业安全的对称算法至少要用90位的钥匙。

The symmetric key systems compared with asymmetric key systems have astounding speed benefits, but managing their keys has always been difficult problem to be solved.

对称密钥系统较之非对称密钥系统具有惊人的速度优势，但是管理对称密钥系统的密钥却是需要解决的一个难题。

Because this is using asymmetric encryption, where each side has its own certificate and private key, it should be somewhat simpler to handle than the Listing 5 symmetric-encryption example.

因为这是使用非对象加密技术，而每一端有自己的证书和私有密钥，比起清单5对称加密技术示例，它处理起来更为简单。

The alternative is symmetric encryption, but with symmetric encryption you must have a secret key known only to the parties involved in a message exchange.

另外一种方法是对称加密，但是使用对称加密时，您必须拥有只有参与消息交换各方才知道的密钥。
