当今社会是信息化的社会。为了适应社会对计算机数据安全保密越来越高的要求,美国国家标准局(NBS)于1997年公布了一个由IBM公司研制的一种加密算法,并且确定为非机要部门使用的数据加密标准,简称DES(Data Encrypton Standard)。自公布之日起,DES算法作为国际上商用保密通信和计算机通信的最常用算法,一直活跃在国际保密通信的舞台上,扮演了十分突出的角色。现将DES算法简单介绍一下,并给出实现DES算法的VC源代码。
DES算法由加密、解密和子密钥的生成三部分组成。-s

1.在电报收发等数据通讯中,常需要将传送的文字转换成由二进制字符0、1组成的字符串来传输。为了使收发的速度提高,就要求电文编码要尽可能地短。此外还要保证任意字符的编码都不是另一个字符编码的前缀,这种编码称为前缀编码。
2.Huffman树可以用来构造编码长度不等且译码不产生二义性的编码。
