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. Platform: |

Description: 文件传输协议FTP是基于TCP / IP的应用层协议,其主要功能是提供文件的共享、支持远距离计算机间接或直接连接、保护用户不因各类主机文件存储器系统的差异而受影响、进行可靠且有效的数据传输等,应用非常广泛。但是传统的FTP有不少的安全漏洞,例如明文传输、缺乏对数据的机密性和完整性保护,对通信双方也没有可靠的认证措施等。针对FTP的安全漏洞,近年来也出现了一些不需要对F IP协议自身做完全更改的协议扩展模块,如FTP SSL /TLS Extension。SSL ( Secure Sockets Layer)是用于对TCP / IP数据流进行加密的协议,同时还包括了身份认证和数据完整性校验等内容。显然,基于SSL /TLS的FTP克服了明文传输的致命弱点,但是无可否认的是,在开放式的互联网环境下FTP服务器受到恶意攻击的可能性还是很大,而且协议数据的安全性还是未得到保障。安全的本质是在信息的安全期内保证其在网络上流动的或
者静态存放时不被非授权用户非法访问,但授权用户却可以访问。基于这一概念,本文在SSL 的基础上设计了一个安全FTP系统,从认证、传输、存储三个方面大大提高了FTP的安全性。-FTP File Transfer Protocol is based on TCP/IP application layer protocol, its main function is to provide file sharing, remote computer support to connect directly or indirectly, to protect users from all types of hosts file memory system affected by the difference between, for reliable and effective data transmission and so on, a wide range of applications. Traditional FTP but there are a lot of security vulnerabilities, such as express delivery, lack of data confidentiality and integrity protection, the two sides of the communication did not credible certification measures. FTP for security vulnerabilities in recent years, there have been some F IP protocol does not need to completely change their agreement to do the expansion modules, such as FTP SSL/TLS Extension. SSL (Secure Sockets Layer) is used for TCP/IP data stream is encrypted agreement also includes authentication and data integrity checking and so on. Obviously, based on SSL/TLS for FTP transmission to overcome the Platform: |

Description: 本书第一部分讲述的是传统的网络接口N e t B I O S、重定向器以及通过重定向器进行的各类网络通信。尽管本书大部分内容均围绕 Wi n s o c k编程这一主题展开，但是， A P I比起Wi n s o c k
来，仍然具有某些独到之处。其中，第 1章探讨的是N e t B I O S接口，它和Wi n s o c k类似，也是
一种与协议无关的网络A P I。N e t B I O S提供了异步调用，同时兼容于较老的操作系统，如 O S / 2
和D O S等等。第2章讨论了重定向器的问题，它是接下去的两个新主题—邮槽（第3章）和
命名管道（第4章）的基础。重定向器提供了与传输无关的文件输入／输出方式。邮槽是一种
简单的接口，可在Wi n d o w s机器之间实现广播和单向数据通信。最后，命名管道可建立一种双向信道，这种信道提供了对Wi n d o w s安全通信的支持。-The first part of the book tells the story of a traditional network interface N et BIOS, redirector and a variety of network communication conducted via redirector. Although most of the book revolves around the themes Wi nsock programming, however, API compared to Wi nsock years, still has some unique. Which is discussed in Chapter 1, N et BIOS interface, and Wi nsock similar, but also a network protocol independent API. N et BIOS provides asynchronous calls, while compatible with older operating systems such as OS/2 and DOS, and so on. Chapter 2 discusses the redirector problem, it is the next two new themes- Mail Slot (Chapter 3) and named pipes (Chapter 4) foundation. Redirect provides a transport-independent file input/output. The mail slot is a simple interface that enables broadcast and one-way data communication between Wi ndows machines. Finally, the named pipe can create a two-way channel, this channel provides support for Wi ndows secure communication. Platform: |

Description: Cloud computing is the one which offers infrastructure to the client on a pay as you use model by leveraging on the Internet technology. As this model depicts the electricity billing it is often termed as utility computing. As the use of cloud increases day by day the concerns of cloud also gets increased. There are number of data breaches that are happening day by day that affect the cloud growth. The major concern in adapting cloud is its security. In order to solve the security issues there are number of solutions proposed. This paper focuses on integrity assurance strategy for remote data. The technique proposed combines the encrypting mechanism along with the data integrity check mechanism. The analysis and simulation results show that our proposed auditing protocols are secure and it reduce the computation load and communication cost of the auditor. Platform: |

Description: The capability of selectively sharing encrypted data with different users via public cloud storage may greatly ease security concerns over inadvertent data leaks in the cloud. A key challenge to designing such encryption schemes lies in the efficient management of encryption keys. The desired flexibility of sharing any group of selected documents with any group of users demands different encryption keys to be used for different documents. However, this also implies the necessity of securely distributing to users a large number of keys for both encryption and search, and those users will have to securely store the received keys, and submit an equally large number of keyword trapdoors to the cloud in order to perform search over the shared data. The implied need for secure communication, Platform: |
