Abstract


With the rapid development of computer network technology, the use of a wide range of open network environment for global communication has become the development trend of the times. However, the network at the same time to provide an open and shared resources, inevitably there is a security risk. Security issues pose a serious threat to the network economy, how to protect the security of the network, in particular the security of information transmitted over the network, has become a focus of attention. Therefore, the research and development of broadly applicable network information security product has great practical value. In this paper, the IP security protocol system IPSec-based virtual private network (VPN) that is widely popular information security technology and its implementation in-depth study. Paper in turn explains the status of the security issues, classification and countermeasures; VPN technology, definitions, classifications and the basis of agreements; composition of the IPSec protocol architecture and key technologies; Finally, specific description of how to use the the IPSec design and construction VPN gateway, and its safety performance test. Involved in research work in this paper the following aspects: (1) VPN technology gives the definition of VPN features and benefits; VPN key technologies; VPN classification and the classification applicable application environment; focusing on comparison of several with has many advantages to achieve the advantages and disadvantages of VPN security protocols and determine IPSec VPN on the basis of key research. (2) IPSec protocol architecture gives the IPSec design purpose, role and composition; analysis of two IPSec security protocols - AH and ESP, including the security features of each protocol, packet format, the application and data packet processing; focuses on the security association (SA) as well as two modes: the means of transport mode and tunnel mode, the organization and management of SA - Security Association Database (SAD), as well as security policy management tools - security policy database (SPD); Finally, the Internet Key Exchange (IKE) are described in detail. (3) the implementation of IPSec protocol detailed analysis of IPSec on Linux an implementation --FreeS/WAN of including its structure and composition; focuses on the FreeS / WAN how to use a combination of SPD and SAD to implement a security policy representation associated with the management, the SPD and SAD data structure, construction method, the search algorithm, and both. (4) Construction and testing of VPN gateway is designed on the basis of in-depth study on IPSec and FreeS / WAN VPN gateway structure contains two of the core module and user module. Then, the detailed description of the structure of the VPN gateway, including system configuration, FreeS / WAN installation and configuration, and a concrete example of the whole process of the structure VPN gateway. Finally, the VPN gateway testing, functional testing and application mode test.
