【Abstract】 Virtual Private Network (VPN) is the security technology by which transferring private information is implemented under open network, and IPSec (IP security) is the efficient measures realizing VPN. In this paper, IPSec protocol architecture is analysed, and the theory design and implementation of VPN under Linux structure are discussed. The security VPN technology of IPSec in tunnel mode is mainly introduced.更多还原
