secret key encryption

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 experimental results show that the identity authentication which integrated iris identify with the secret key encryption technique can effectively control the resource access on WWW in security and can effectively reduce the probability which being attacked.

实际测试的结果表明，虹膜识别与网页结合的身份认证，能够达到控制网站上资源存取的目的，较大程度地减小了攻击者破解的可能性。

SymmEncr: Require symmetric encryption using a client-generated secret key.

SymmEncr：需要使用一个客户端生成您的密钥进行对称加密。

Hadorwould traditionary symmetry encryption and publicity secret key mode band together, have two both the virtue.

将传统的对称性加密与公开密钥方法结合起来, 兼备了两者的优点.

The advantages of this algorithm were, rapidity of encryption, carried out easily by computer, ampliative secret key space and so on.

该算法有加密速度快、易于计算机实现、密钥空间大等优点。

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。

So-called perfect secret system means that when translator occupy all encryption technologies and own the infinite calculation resources, he can't still calculate out the true key.

所谓的完善保密是指破译者在占有全部密码算法且拥有无限计算资源的前提下也不能有效地求出密钥。
