1、 所有密钥的装载与导出都采用密文方式；
2、 密钥管理系统采用3DES加密算法，采用根密钥生成系统、主密钥生成系统、初始化卡生成系统、密钥注入系统四级管理体制；
3、 在充分保证密钥安全的基础上，支持IC卡密钥的生成、注入、导出、备份、更新、服务等功能，实现密钥的安全管理；
(1, the loading and export all keys are in cipher text 2, the key management system uses the 3DES encryption algorithm, using the root key generation system, the master key generation system, initialize the card generation system, key injection system four management systems 3, the key to ensure full security, based on the support of the IC card key generation, injection, export, backup, update, and service functions to achieve key security management )

DES( Data Encryption Standard)算法，于1977年得到美国政府的正式许可，是一种用56位密钥来加密64位数据的方法。虽然56位密钥的DES算法已经风光不在,而且常有用Des加密的明文被破译的报道,但是了解一下昔日美国的标准加密算法总是有益的,而且目前DES算法得到了广泛的应用,在某些场合,她仍然发挥着余热.（如：UNIX的密码算法就是以DES算法为基础的）。将其修改为三重DES也能抵抗破解。下面是关于如何实现DES算法的语言性描述：(DES ( Data Encryption Standard ) algorithm, in 1977 the U.S. government s official permission , is a 56 -bit key to encrypt 64 data . 56 keys of the DES algorithm scenery is not , and often with Des encryption expressly decipher reported , but look at the old standard encryption algorithm is always useful , but the DES algorithm has been widely used in a some occasions , she still plays a waste heat . (such as : UNIX password algorithm is DES algorithm -based ) . To modify the Triple DES is also resistant to cracking . The following is a description language on how to achieve the DES algorithm :

Caesar-code
凯撒密码作为一种最为古老的对称加密体制，在古罗马的时候都已经很流行，他的基本思想是：通过把字母移动一定的位数来实现加密和解密。例如，如果密匙是把明文字母的位数向后移动三位，那么明文字母B就变成了密文的E，依次类推，X将变成A，Y变成B，Z变成C，由此可见，位数就是凯撒密码加密和解密的密钥。个人原创。(Caesar password as one of the most ancient symmetric encryption system in ancient Rome have been very popular, his basic idea is: by the letters move a certain number of bits to achieve encryption and decryption. For example, if the key is the number of bits of plaintext letters backward move three, the plaintext letter B into a ciphertext E, and so on, X will become Y-become a B,, and Z becomes C Thus, the median is the Caesar cipher encryption and decryption keys. Personal originality.)
