Wherein, H is hash algorithm, such as SHA1, and SHA256 etc., OS are operating system and its version information, and Vendors is to produce
Quotient, Device are the sequence number of hardware information such as hard disk, memory, CPU of equipment etc..
Second step, IoT equipment is registered to block chain network: business men is by the IoT product oneself produced to block chain network
Registration, detailed process is by the ID of IoT equipment, characteristic information (such as hardware information, operating system, the product serial of IoT equipment
Number, business men information etc.), and by above- mentioned information Hash, then with being published to the public of block chain network after the private key signature of business men
Account book, to register the ID of the IoT equipment to block chain network.
Step 3: IoT equipment identifies: user uses whether IoT equipment need to verify IoT equipment to block chain network for the first time
For believable equipment.Specifically, IoT equipment can issue the device id to block chain network first when equipment starts for the first time
And corresponding facility information and signature, after block chain network receives checking request, block chain node, which needs to verify the information, is
No is legal IoT equipment, once being verified, which can access block chain network.
Step 4: user authentication IoT equipment: once the identification work of IoT equipment is completed, user can pass through fingerprint and hand
Machine receive identifying code as user identity ID (wherein, ID=H (H (finger print information)+H (identifying code))) by IoT equipment with set
The identity of standby owner is bound, i.e., IoT device id is associated with to the ID of a certain user, realizes equipment certification, user can also
The information such as preference are used so that the system of IoT equipment is arranged.And by device id, the characteristic information of IoT equipment, user identity ID,
The signing messages of business men, system are using being published to block chain network after the Information Signature such as preference.
Step 5: isomery IoT device authorization accesses: different types of IoT equipment can pass through the use in block chain network
Family ID is associated, realizes interconnecting between variety classes equipment.User can also by block chain realize from it is different
The business demands such as the access of IoT device authorization, information sharing.
In conclusion a kind of internet of things equipment identity identifying method and system based on block chain of the present invention is more by extracting
Dimension IoT equipment feature is registered using after encryption, signature generation internet of things equipment identity ID to block chain network, and in for the first time
When using IoT equipment, to block chain network issue identification certification request, so as to detect user purchase IoT equipment whether be can
The IoT equipment of letter, and after being verified, user identity ID is generated, and user identity ID is bound with internet of things equipment,
Realize the purpose of the internet of things equipment authentication based on block chain network, different business mens and not of the same race may be implemented in the present invention
