High-intensity data confidentiality as all the data transmitted via the Internet, it must be data encryption and data integrity protection. VPN Virtual Private Network General provided more than 128-bit symmetric encryption, asymmetric encryption algorithm using 1024-bit, and a network protocol stack on the application layer VPN technology, all with one-time password system, data security is extremely high. VPN Virtual Private Network data also MD5 digest algorithm used to protect the integrity of the data transfer process. The general does not provide any form of telecommunication line of encryption, VPN technology, while it built on the Internet on top, but its high-strength encryption measures to make the security of data telecommunication line is much higher than the average. IP VPN is established through an open IP network of private data transmission channel, to remote branch offices, business partners, and other mobile workers connecting a private network technology. For enterprises, IP VPN alternative to traditional leased lines to connect to a computer or local area network and so on. Any IP VPN services are based on the tunneling technology, the VPN tunnel mechanism is the key to the implementation. Therefore, IP VPN is one of the main tasks of standardization standardization of the tunnel mechanism.
