Based on system software architecture in the credible platform connection system and embodiment two in embodiment one, the present embodiment is proposed
A kind of credible platform connection method, as shown in Fig. 2, including that user identity identifies, platform security identifies and according to identification
As a result three big steps of control network connection, the detailed process of the method are as follows:
1) connection prepares: before connection starts, Windows terminal and server incoming end passes through binding TPCM relevant interface
Carry out integrality collection；
2) user sends network insertion request to gateway；
3) user and gateway carry out user identity identification.Pass through code key agreement protocol based on trusted third party authentication center,
Communication code key Key is established, after communication code key is established, user encrypts relevant information U (id, password) by code key, sends
It compares, is identified with stored information after gateway decryption to gateway, enter step 4) if if identifying, otherwise refuse
The access request；
4) user sends platform identification request to Windows terminal, and gateway sends platform identification to server-side access point and asks
It asks；
5) after server-side access point receives platform identification request, a wheel is executed with Third Party Authentication center or takes turns platform mirror more
Other agreement realizes that the platform between access requestor and access control person identifies；
6) in platform discrimination process, Windows terminal and service termination access point pass through each of the IF-IMC and TPCM of platform
A IMC carries out information exchange, obtains integrity information M (hard disk information, memory information, operating system version, the important benefit of platform
Fourth, the network information, associated drives etc.), trusted third party carries out information exchange by IF-IMC and the IMC of storage and obtains standard value
Information M '；
7) in platform discrimination process, other than platform essential information, it is also necessary to the multidate information of collection system, i.e. behavior letter
Breath.TPCM calls IF-AGC interface to be collected behavior, and behavior includes the current running environment of computer, such as application operating
Whether rule is met, with the presence or absence of unauthorized access, whether legal, the network request situation of the sequence of operation etc.；
8) in platform discrimination process, the completeness check interface of storage calls in trusted third party, to user and gateway
Platform integrity metric value is verified and is assessed (i.e. verifying M==M '), and trusted third party generates user according to assessment strategy
With the completeness of platform assessment result of gateway, Windows terminal and service termination access point are sent by completeness of platform result；
9) assessment result that Windows terminal and service termination access point are generated according to trusted third party respectively generates access and determines
Plan is sent respectively to user and gateway；
10) user and gateway execute access control according to the access decision of generation, and gateway is according to the access decision control of generation
System (the allow, refusal) access of user to protected network, user according to the access decision of generation decide whether to be connected to this by
The network of protection, to realize that Windows trustable network connects.
The invention proposes a kind of credible platforms to connect system and method, using credible network connecting construction, in conjunction with user
Behavioural analysis realizes that the user identity that network is accessed under Windows environment identifies, bi-directional platform identifies and completeness of platform mirror
Not, it enables Windows server carry out authentic authentication to the behavior of access terminal, is decided whether to allow safety according to identification result
Network request access, to realize believable network connection.
