Specific embodiment
Below in conjunction with drawings and Examples, the present invention is described in further detail.
The network data security transmission method of the present invention, for realizing that message sender is network with message receiver Data communication, has set up the secure communication channel for transmission data, that is, has built between message sender and message receiver The communication channel that the SSL/TLS based on certificate connects is found.
The specific implementation for setting up secure communication channel is：
Ca authentication certificate, service end certificate, client certificate, ca authentication certificate pair are generated initially with the close algorithm of related state The certificate of service end and client is signed, it is ensured that the security of certificate, and a ca authentication certificate can be to multiple service ends Certificate and client certificate are signed.Ca authentication certificate and service end certificate, client is deposited between in the message in part service end End is communicated with message-oriented middleware using its client certificate, after certification authentication passes through, is set up credible connection, that is, is set up secure communication Channel.
As Figure 1-3, network data security transmission method disclosed by the invention, comprises the following steps：
S1：Message receiver, based on credible platform module (TPM：Trusted Platform Module) close ellipse using state Circular curve public key algorithm SM2 creates public private key pair, and credible platform module preserves private key, exports public key, should to certification authority's registration Public key, applies and generates public key certificate；
The certification authority is the organization based on PKIX PKI.
S2：Message sender, obtains the public key certificate from certification authority, and it is close to generate session based on credible platform module Key；
Credible platform module provides interface and generates random key, and the key is session key.
S3：The initial data that message sender is sent to message receiver, generates digital envelope after process, sends to disappearing Breath recipient：
