Second chapter narrated the cryptology elementary knowledge.

第二章讲述了密码学的基础知识。

Firstly, cryptology and related theory is summarized. Especially, multimedia encryption algorithms are classified and their characteristics are studied in detail.

首先，概括总结了密码学的相关理论基础，特别分类研究了适用于多媒体数据加密的算法及其特点。

In this article, the fundamental knowledge of cryptography are introduced first. The author introduces the message digest algorithm, digital signature and X.509 certificate which are the foundations of authentication in public-key systems.

本文首先介绍了密码学方面的基础知识，接着介绍了身份认证中的消息摘要算法和数字签名的原理以及X.509证书，这些是公钥加密体系中身份认证的基础。

Based on the embedded system and cipher technology, a digital speech scrambler is designed and realized in this thesis which can security transmit speech, video, fax and data.

本文利用嵌入式系统技术和密码学技术，利用现有的PSTN或ISDN，采用先进的分组加密算法，设计实现了基于EPSON 33209 体系的数字语音保密电话，实现语音、视频、传真及数据的安全传输。

The traditional method of cryptology is that information has been encrypted by itself, but the transmission process of the information is exposed, But information hiding technology has enshroud its transmission process.

传统的密码学方法是将信息本身进行了保密，但是信息的传递过程是暴露的，而信息隐藏技术，则是将信息的传递过程进行了掩盖。

In identity encryption area, Enyo is situated the first rank of the world, applied for many international and national patents successfully, and also holds security mail technology and products that only possessed by Enyo-Tech.
