Description: 截包的需求一般来自于过滤、转换协议、截取报文分析等。 过滤型的应用比较多，典型为包过滤型防火墙。 转换协议的应用局限于一些特定环境。比如第三方开发网络协议软件，不能够与原有操作系统软件融合，只好采取“嵌入协议栈的块”（BITS）方式实施。比如IPSEC在Windows上的第三方实现，无法和操作系统厂商提供的IP软件融合，只好实现在IP层与链路层之间，作为协议栈的一层来实现。第三方PPPOE软件也是通过这种方式实现。 截取包用于分析的目的，用“抓包”描述更恰当一些，“截包”一般表示有截断的能力，“抓包”只需要能够获取即可。实现上一般作为协议层实现。 本文所说的“应用层截包”特指在驱动程序中截包，然后送到应用层处理的工作模式-cut the demand for general packet from the filter, change the agreement, reported the interception of text analysis.

Description: The basic parts of the BFSK transmitter are the preamble and the data input circuit. The preamble sequence is positioned in front of each packet of 122 bits for a total of 128 bits packet. The main purpose of the preamble is to facilitate the reception, providing both bit and packet synchronization. The data input circuit mainly consists from memory elements and a convolutional encoder with r=1/2. Thus, the input bits must be stored in a temporary memory and be partitioned in blocks of 61 bits. Then the convolutional encoder doubles the bits and adds two more trail bits at the end of the message. A multiplexer makes sure that that the correct sequence, choosing between preamble and encoded bit, is propagating to the next stage. The next stage of the transmitter consists of two direct digital synthesizers (DDS), and a multiplexer that is fed with zeros and ones to choose between the two frequencies. For each bit, we allow 64 samples of the respective frequency to be transmitted. Although the implementation of the selection between the two frequencies is strait forward, the enable port of the multiplexer should be used along with a Matlab Code (MCode) block in order to prevent the propagation of some initial undefined states during initialization. The only functionality of the MCode block is to enable the multiplexer after the first bit of the preamble is detected. Finally, pulse shaping is not used and the addition of a single filter after the last multiplexer would suffice to implement this functionality.

Description: 对称/分组密码一般分为流加密(如OFB、CFB等)和块加密(如ECB、CBC等)。对于流加密，需要将分组密码转化为流模式工作。对于块加密(或称分组加密)，如果要加密超过块大小的数据，就需要涉及填充和链加密模式，文中提到的ECB和CBC等就是指链加密模式。 本文将要介绍了AES对称加密/分组加密/流密码及其ECB、CBC、CFB、OFB和CTR五种对称加密模式。-Symmetric/block ciphers are generally divided into stream encryption (eg, OFB, CFB, etc.) and block encryption (such as ECB, CBC, etc.). For streaming encryption, block cipher needs to be translated into the work flow model. The encryption block (or block cipher), If you want to encrypt the data block size more than on the need to involve filling and chain encryption mode, the text referred to, such as ECB and CBC encryption mode refers chain. This paper will be introduced the AES symmetric encryption/packet encryption/stream cipher and the ECB, CBC, CFB, OFB and CTR mode in five symmetric encryption.

实验报告DES是Data Encryption Standard(数据加密标准)的缩写。它是由IBM公司研制的一种加密算法，美国国家标准局于1977年公布把它作为非机要部门使用的数据加密标准，二十年来，它一直活跃在国际保密通信的舞台上，扮演了十分重要的角色。DES是一个分组加密算法，分组长度为64b，密钥长度也为64b,但因为含有8个奇偶校验比特，所以实际密钥长度为56b。DES算法是迄今为止使用最为广泛的加密算法。
有关算法的详细介绍请参阅教材。- Network security technology, the report experimental DES is Data Encryption Standard (Data Encryption Standard) abbreviation. It is developed by IBM as a encryption algorithm, the United States National Bureau of Standards published in 1977 as the use of non-confidential data encryption standard, the last two decades, it has been active in the international arena and secure communication played a a very important role. DES is a block cipher algorithm, packet length 64b, key length for 64b, but because containing eight parity bits, so the actual length of the key 56b. DES algorithm is by far the most widely used encryption algorithm. Details on the algorithm please refer to materials.
