Problems solved by technology

So there is a serious conflict between the two technologies
In addition, in the key exchange mechanism, the existing schemes do not consider the characteristics of long delay and high bit error of the space link, and the number of information exchanges on the space link is too much

Abstract

The invention provides a design and implementation method of lightweight high-performance virtual private network software, the method comprising: sending node I and receiving node R negotiate to generate a secure session SA2, and network layer agent gateways X and Y serve as intermediate nodes and nodes I and R jointly negotiate to generate a secure session SA1, and transmit the negotiation messages related to proxy gateways X and Y to the wireless link. The invention proposes a design and implementation method of lightweight high-performance virtual private network software, which inherits the advantages and security of key exchange of the virtual private network, is suitable for wireless link characteristics, and reduces the amount of data calculation.

Description

technical field [0001] The invention relates to a virtual private network, in particular to a design and realization method of lightweight high-performance virtual private network software. Background technique [0002] The application of TCP / IP technology to the enterprise mobile network has become the development trend of the current enterprise mobile network. In the enterprise mobile network, due to the characteristics of high bit error, long delay, and asymmetric uplink and downlink, the network transmission performance is low. In the prior art, a network layer proxy gateway is deployed between wireless links to realize enhanced IP connection. The VPN technology encrypts the IP message as a whole, and only the communication parties can decrypt the data. In the network layer proxy gateway, the header needs to be read separately. So there is a serious conflict between these two technologies. In addition, in the key exchange mechanism, the existing schemes do not consid...
