Step 7: cert services cluster is completed to sign using system root certificate to certificate request, generates effective device certificate
It is sent to IOT service cluster, IOT service cluster sends Internet of Things for certificate by Mqttbroker cluster and load balancing and sets
It is standby；
Step 8: Physical Network equipment sends activation success message to IOT service cluster after receiving certificate and disconnects two-way
TLS connection；
Step 9: internet of things equipment establishes new pair using root certificate, device certificate and device keys and IOT service cluster
To TLS connection, internet of things equipment only has the subscription/publication permission of sign test Topic at this time；
Step 10: internet of things equipment sends cert services cluster for device certificate abstract and carries out sign test, after sign test success
IOT service cluster is in the subscription/publication permission of database update internet of things equipment, and internet of things equipment can be ordered normally at this time
It reads/issues.
Further, whether it is specially to have to recognize to the querying service database equipment that ID is activated in the step 6 effectively
Demonstrate,prove permission.
Further, the certificate in the step 1-10 is the certificate for meeting X509 specification.
Compared with prior art, the present invention having the following advantages that and effect:
1, activate certificate and activation key only a set of for all devices, facilitating equipment end programming, (device id can be with
It is the information of equipment itself, such as MAC Address, is not necessarily to programming)；
2, activation process is protected by two-way TLS, and safety is secure；
3, it is close that a machine one has been truly realized in equipment normal course of communications；It is kept away by way of preset activation certificates/keys
Exempt from the device certificate/key different for each equipment programming, facilitates equipment production flow；
4, device keys are locally generated by equipment, other Anywhere without copy, prevent what device keys batch was lost
Possibility；Device keys are that equipment locally generates, and will not be ensured in the mode that transmission over networks, device certificate are issued online each
A equipment is all that a machine one is close.
5, device id is preserved in device certificate, platform can confirm the connection, subscription, publication permission of equipment by certificate
Equipment subscription/publication, permission and certificate information are bound, and safety is higher.
