symmetric key cryptography

基本解释

In studying symmetric-key (secret key) cryptography algorithm, the disadvantages of DES and the advantages of AES are analysed.
在对称（私钥）密码算法方面，重点研究DES存在的问题和AES的特点；
The two main competing cryptography schemes are known as the secret-key (symmetric) system and the public-key (asymmetric) system.
现有两种主要的、相互竞争着的密码术，被称作秘钥（即对称）系统和明钥（即不对称）系统。
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。
