As certificate server firstly generates the private key and public key that occur in pairs, and pass through public key is passed through it is raw after specific Hash and coding
At the second block chain address.Wherein, private key is grasped by their own without being published in network, and it includes it to be sent to the system of support
When support system receives the second certification request block chain is written in the public key of certificate server by the second certification request of public key
In, certificate server just completes the registration of block chain network as a result,.
Using the above method, its public key is written to area by certificate server in registration by the support system of mobile network
In block chain, user equipment inquires the public affairs that certificate server can be obtained in block chain according to the second block chain address of certificate server
Key.In this way, user equipment carries out signature authentication according to the public key of certificate server to the second signing messages of certificate server, if
Signature authentication success then can determine that the certificate server of request certification has grasped private key corresponding with the public key, thus can be shown that this
Certificate server is legal.
Since the information being written in block chain has the characteristic that can not be distorted, so that user equipment can be according to true
Whether the certificate server of the public key of believable certificate server, checking request certification is legal, to ensure that certificate server
It can not pretend to be.
