说明：  鉴于语音信号的“即时性 ”特点 ,在分析了混沌掩盖、混沌调制进行加密利弊的基上 ,构造了一种混沌切换加密方案 ,对语音进行了更安全有效地加密.(DESIGNOFVOICEENCRYPTIONCOMMUNICATIONSYSTEMBASEDONCOMPUTERNETWORK)

数字签名的基础是公钥和私钥的非对称加密，发送者使用私钥加密消息摘要（签名），接收者使用公钥解密消息摘要以验证签名是否是某个人的。(The foundation of digital signature is asymmetric encryption of public key and private key. The sender encrypts message digest (signature) with private key, and the receiver decrypts message digest with public key to verify whether the signature is someone.)

SHA1安全哈希算法（Secure Hash Algorithm）主要适用于数字签名标准 （Digital Signature Standard DSS）里面定义的数字签名算法（Digital Signature Algorithm DSA）(SHA1 Secure Hash Algorithms are mainly applicable to Digital Signature Algorithms (DSA) defined in Digital Signature Standard DSS.)

为了保证数字图像的安全性和可靠性,提出混沌序列对称加密算法对数字图像进行加 密的方法，设计了基于Logistic 映射模型的四维混沌序列对称加密算法,实现对数字图像的混 沌加密及解密。而高维混沌系统具有更高的安全性的特点，能够抵御统计攻击，穷举攻击， 具有较强的抗干扰能力。(Digital image encryption algorithm based on four-dimensional chaotic system implementation)

PGP Components使用PGP算法的加密控件。(有源代码）工作在：D2 D3 D4 D5。作者：Michael in der Wiesche--Encryption control that PGP Components uses PGP arithmetic to realized.It works in D2 D3 D4 D5。author:Michael in der Wiesche

密码学文献有一个奇妙的发展历程，当然，密而不宣总是扮演主要角色。第一次世界大战前，重要的密码学进展很少出现在公开文献中，但该领域却和其它专业学科一样向前发展。-cryptography literature has a wonderful history, of course, close does not declare always played the leading role. Before the First World War, it was important to cryptography little progress emerged in the open literature. However, the area has other professional disciplines and the development of the same.

这只是标准DES算法的例子,必须在WINDOWS环境下编译.(This is just the standard DES algorithm, which must be compiled in the WINDOWS environment.)
