Description
Technical field
The present invention relates to trustable network access field, specifically a kind of high concurrent strategic decision-making system, trustable network
System and cut-in method.
Background technique
TNC (full name in English is Trusted Network Connect, and translator of Chinese is trustable network access), as TCG
A branch in (full name in English is TrustedComputing Group, and translator of Chinese is Trusted Computing Group), it is special negative
Blame the Trustworthy task that the network terminal networks.
Trustable network refers to before terminal connects network, authenticates to the identity of user.If certification passes through, to end
The identity of end platform is authenticated, if certification passes through, is measured to the platform credible state of terminal, if measurement results are full
The security strategy being connected to the network enough, then allow terminal connect network, otherwise terminal is connected to specified area of isolation, to its into
Row safety repairing and upgrading.
Current trustable network system is for can satisfy the use of user when terminal quantity scale is not too big, but when can
When terminal quantity is more than certain scale in communication network system, the framework of current trustable network cannot meet system requirements, portion
The waiting of some time is just had during point terminal trustable network access, reduces user experience.
Netfilter is the subsystem that Linux 2.4.x is introduced, its general, abstract frame as one mentions
For the administrative mechanism of a whole set of hook function so that such as Packet Filtering, network address translation (NAT) and be based on protocol class
The connection tracking of type becomes possibility.The related mechanism for how utilizing netfilter, avoids mass termination trustable network access
The system delay of Shi Fasheng is the technical issues that need to address.
