symmetric cryptography

key management subsystem supports the symmetric cryptography and asymmetric cryptography and abstract cryptography.

支持个人化过程中要求的对称算法、摘要算法和非对称算法等。

To start with, cryptography is introduced from encryption and decryption, symmetric secret key encryption, public key encryption and password analysis.

首先从加密和解密、对称密钥加密、公钥加密、密码分析等方面对密码学进行了简单的介绍。

The encryption scheme in modern cryptography includes symmetric encryption and asymmetric encryption and the former is further classified as block cipher, stream cipher and hash function.

现代密码学中加密算法包括对称加密和非对称加密，前者又分为分组密码，流密码和Hash函数。

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。

As the basis and core of information security, cryptography also attracts more and more attention. Brute force attack on symmetric cipher algorithms is an important direction of cryptography.

密码学作为信息安全的基础和核心，也越来越受到人们的关注，而暴力破解对称密码算法，是密码学研究的一个重要方向。

in symmetric cryptography systems, a single key that is used for both encryption and decryption.

在对称密码术系统中同时用于加密和解密的单个密钥。
