Description: 对称密码体制的发展趋势将以分组密码为重点。分组密码算法通常由密钥扩展算法和加密（解密）算法两部分组成。密钥扩展算法将b字节用户主密钥扩展成r个子密钥。加密算法由一个密码学上的弱函数f与r个子密钥迭代r次组成。混乱和密钥扩散是分组密码算法设计的基本原则。抵御已知明文的差分和线性攻击，可变长密钥和分组是该体制的设计要点。

Description: Huffman编码又称哈夫曼编码，是一种可变长编码方式.码的原理是：将使用次数多的代码转换成长度较短的代码，而使用次数少的可以使用较长的编码，并且保持编码的唯一可解性。Huffman算法的最根本的原则是：累计的(字符的统计数字*字符的编码长度)为最小，也就是权值(字符的统计数字*字符的编码长度)的和最小。-Huffman coding, also known as Huffman coding is a variable length encoding. Code principle is: use the number code conversion grow shorter code, use fewer can use a longer encoding andmaintain encoded solvability. Huffman algorithm is the most fundamental principles are: cumulative (character statistics* character encoding length) is the smallest, is the right value (character statistics* character encoding length) and the minimum.

Description: tcp nio 服务端、客户端例子--参考《分布式Java应用：基础与实践》
参考《分布式java应用》tcp nio 服务端、客户端例子， 在基础主要做了以下调整：
1. 信息长度由定长（ByteBuffer长度）修正为可变长（即不再收长度限制）
2. 特殊错误处理：read Exception，opposite close Exception，select timeout Exception（网络超时）。
read Exception 与 opposite close Exception 的处理， 用于解决发现异常后造成程序的 while死循环。
select timeout Exception的处理， 用于对网络超时的支持
-the tcp the nio service side, client examples- refer to distributed Java applications: Basis and Practice of " reference" distributed java applications " tcp nio services, client, example, is based primarily on the following adjustments: 1. message length fixed-length (length of the ByteBuffer) correction is a variable length (ie, no longer received length limit) 2. special error handling: read the Exception, opposite the close the Exception, select timeout Exception (network timeout). the read the Exception, and opposite the close Exception handling is used to resolve discovered anomalies resulting from the program while infinite loop. select timeout of Exception handling, for the support of the network timeout
