Research on Network Security Based on IPSec

With the development of information technology, Network security issues are very prominent, Network security incidents occur frequently. In order to enhance network security, we must take certain measures that are the use of IP protocol. IP protocol also called Internet Protocol. As defined in the network layer in the internet important agreement, is the current implementation of the network communication between the computer requirements. As a security model, IPSec is based on end-to-end trust and security between the source IP address and the destination IP address. IPSec network transmission protocol is developed mainly to solve the network layer security issues, and IP protocol to improve the confidentiality and integrity. It is necessary to apply the IPSec to the new IPv6 network protocol. Through the use of IPSec, you can build a more secure and reliable network environment, which provides more spaces for the development of the Internet and e-commerce.
