) Compression using huffman code -with a number of bits k per code word -provide huffman table Huffman coding is optimal for a symbol-by-symbol coding with a known input probability distribution.This technique uses a variable-length code table for encoding a source symbol. The table is derived in a particular way based on the estimated probability of occurrence for each possible value of the source symbol .Huffman coding uses a specific method for representing each symbol, resulting in a prefix code that expresses the most common characters using shorter strings of bits than those used for less common source symbols.The Huffman coding is a procedure to generate a binary code tree.

本文提出了网络编码，减少了验证对飞块成本，有效地防止恶意块的传播实用的安全解决方案。在我们的方案中，用户不仅合作发布内容，但用户也合作来保护自己免受恶意用户通知受影响的节点时，一个恶意的块被发现。(This paper presents a practical security scheme for network coding that reduces the cost of verifying blocks on-the-fly while efficiently preventing the propagation of malicious blocks. In our scheme, users not only cooperate to distribute the content,but (well-behaved) users also cooperate to protect themselves against malicious users by informing affected nodes when a malicious block is found.)
