Claim 0:
1. A blockchain-enhanced open Internet of Things (IoT) access architecture, comprising: an access point, an IoT device, a blockchain mining network, and a core network; wherein the access point provides a short-packet access service to the IoT device, and a process of the short-packet access service is controlled by a blockchain enabling mechanism;
wherein control steps of the blockchain enabling mechanism comprises:
1) depositing, by the IoT device, a predetermined amount of tokens into a blockchain account of the IoT device before accessing an IoT network, wherein registration information is recorded in a blockchain;
2) filling in and signing, by the IoT device, a smart contract comprising details of the short-packet access service before the short-packet access service starts, and performing, by the IoT device, a hash operation by using the smart contract, a to-be-transmitted short packet, a device identification code, and a timestamp, wherein when a hash operation output of the IoT device meets an access condition required by the access point, the IoT device sends the smart contract, the to-be-transmitted short packet, and the hash operation output meeting the access condition of the access point together to request the access point to provide the short-packet access service; and
3) checking and verifying, by the access point after receiving the to-be-transmitted short packet and the smart contract from the IoT device, whether the hash operation output of the IoT device has an access condition required by a current access point, and checking and verifying content and a signature of the smart contract, and an account balance of the IoT device, wherein after a verification succeeds, the access point uploads the smart contract and a hash value of the to-be-transmitted short packet to the blockchain mining network, and directly uploads the to-be-transmitted short packet sent from the IoT device to the core network to complete the short-packet access service.
