Description

Technical Field

[0001] The present invention relates to the technical field of smart lock management, and in particular to a smart lock unlocking system based on the Internet of Things and a storage medium thereof. Background Art

[0002] With the continuous progress of society and the sustained development of economy, the use of locks and keys in various industries has gradually shown a diversified development trend. For example, the one-key unlocking in the power industry, the multi-key one-locking in the logistics and transportation industry, the master key system in the financial industry, etc. In order to meet the special needs of these industries, a number of new functional locks have emerged in the market, such as mechanical unlocking, mechanical key master locks, etc. Although these locks have been partially optimized in terms of usage compared to traditional locks and have achieved certain results, they cannot completely meet industry needs and solve key problems. Summary of the invention

[0003] The present invention provides an intelligent lock and unlocking system based on the Internet of Things and a storage medium thereof. The intelligent key is authorized by the intelligent lock and unlocking method stored on the storage medium, and a passive intelligent lock is used to lock various passage doors, protective screen cabinets, equipment and ladders related to production safety management in power enterprises, thereby realizing the informatization and electronicization of the unlocking operation process.

[0004] In order to achieve the above technical objectives, the present invention provides the following technical solutions:

[0005] A smart lock unlocking method based on the Internet of Things comprises the following steps:

[0006] Step 1: Build a control computer cluster. The control computers in the control computer cluster jointly build a blockchain co-governance management network with equal identities.

[0007] Before entering the IoT smart lock unlocking system under the control of the gateway, the control computer nodes, smart keys and passive smart locks in the blockchain co-governance management network need to perform the following initialization operations:

[0008] The control computer node in the blockchain co-governance management network enters its own device fingerprint information into the public database of the IoT smart lock unlocking system under the jurisdiction of the gateway and loads the common information in the IoT smart lock unlocking system under the jurisdiction of the gateway and the communication credentials of the control computer node in the blockchain co-governance management network and the co-governance credentials of the blockchain co-governance management network to which it belongs;

[0009] The smart key enters its own device fingerprint information into the public database of the IoT smart lock unlocking system under the jurisdiction of the gateway and loads the shared information in the IoT smart lock unlocking system under the jurisdiction of the gateway and the co-governance certificate of the blockchain co-governance management network;

[0010] The passive smart lock enters its own device fingerprint information into the public database of the IoT smart lock unlocking system under the jurisdiction of the gateway and loads the shared information in the IoT smart lock unlocking system under the jurisdiction of the gateway and the co-governance certificate of the blockchain co-governance management network;

[0011] Step 2: The control computer node in the blockchain co-governance management network authorizes the smart key. The specific process is as follows:

[0012] Based on the shared information in the IoT smart lock unlocking system under the control of the gateway, the smart key is set with the permission certificate for opening the passive smart lock, and then the first permission auxiliary application information, the second permission auxiliary application information and the third permission auxiliary application information are calculated and transmitted to the control computer node in the blockchain co-governance management network;

[0013] When a control computer node in the blockchain co-governance management network receives permission assistance application information, a control computer node in the blockchain co-governance management network is set as a proxy node and the remaining control computer nodes are set as non-proxy nodes. The proxy node executes smart contract I;

[0014] Smart Contract I: When the smart key applies to the control computer node in the blockchain co-governance management network for the permission certificate for opening the passive smart lock, the proxy node in the blockchain co-governance management network begins to verify the legitimacy of the identity of the smart key;

[0015] When smart contract I is successfully executed, set the non-agent nodes in the blockchain co-governance management network to execute smart contract II;

[0016] Smart Contract II: When Smart Contract I is successfully executed, the non-agent nodes in the blockchain co-governance management network begin to verify the legitimacy of the identity of the smart key and the agent node;

[0017] After the identity authentication of the smart key and the proxy node is successful, the non-proxy nodes in the blockchain co-governance management network jointly generate and send permission auxiliary challenge information to the smart key;

[0018] The smart key confirms the validity of the permission auxiliary challenge information, and after confirming that the verification is successful, generates the fourth permission auxiliary application information using the permission certificate, and sends the fourth permission auxiliary application information to the control computer node in the blockchain co-governance management network as a response;

[0019] When the control computer node in the blockchain co-governance management network receives the fourth permission auxiliary application information, the control computer in the blockchain co-governance management network is set to execute smart contract III;

[0020] Smart Contract III: When receiving the fourth permission auxiliary application information, the control computer node in the blockchain co-governance management network verifies the consistency of the response information and the challenge content;

[0021] When Smart Contract III is successfully executed, the control computer node in the blockchain co-governance management network authorizes the smart key and records the fourth permission auxiliary application information in the public database as the authorization certificate. The smart key officially obtains the permission certificate for opening the passive smart lock.

[0022] The control computer nodes in the blockchain co-governance management network authorize the unlocking user and send the unlocking user's identity information to the smart key;

[0023] Step 3: The smart key uses the permission certificate to open the passive smart lock. The specific process is as follows:

[0024] Collect the identity information of the unlocking user and compare it with the identity information of the unlocking user issued by the control computer node in the blockchain co-governance management network. When the comparison is correct, the unlocking user uses the smart key to open or close the passive smart lock. The specific process is as follows:

[0025] When the smart key opens the passive smart lock, the smart key supplies power to the passive smart lock and communicates with it, and the passive smart lock loads the second authority auxiliary application information and the fourth authority auxiliary application information from the smart key;

[0026] The passive smart lock authenticates the smart key. When the authentication of the smart key is correct, the unlocking user turns the mechanical key component of the smart key, and the passive smart lock opens and simultaneously uploads the opening status information to the control computer node in the blockchain co-governance management network.

[0027] When the smart key performs a locking operation on the passive smart lock, the smart key supplies power to the passive smart lock and communicates, and the passive smart lock loads the second authority auxiliary application information and the fourth authority auxiliary application information from the smart key;

[0028] The passive smart lock authenticates the authority of the smart key. When the authority of the smart key is correctly authenticated, the unlocking user turns the mechanical key component of the smart key, the passive smart lock locks and simultaneously uploads the locking status information to the control computer node in the blockchain co-governance management network.

[0029] A smart lock unlocking system based on the Internet of Things, the system is used to execute the smart lock unlocking method, including a management and control computer cluster, a smart key, a passive smart lock, a gateway and a public database of the Internet of Things smart lock unlocking system under the control of the gateway;

[0030] The control computer in the control computer cluster communicates with the smart key and the passive smart lock respectively through the gateway;

[0031] The control computer cluster is set to consist of at least four control computers, and the control computers in the control computer cluster jointly build a blockchain co-governance management network with equal identities.

[0032] Preferably, the management and control computer directly binds the user information with the smart key when allocating permissions and indirectly matches the user information with the passive smart lock.

[0033] A management and control computer includes a processor, a memory, a network interface and a database connected through a system bus, wherein a computer program is stored in the memory, and the computer program is characterized in that when the computer program is executed by the processor, the steps of the smart lock unlocking method based on the Internet of Things are implemented.

[0034] A computer-readable storage medium stores a computer program, which, when executed by a processor, implements the steps of a smart lock unlocking method based on the Internet of Things.

[0035] Compared with the prior art, the present invention has the following beneficial technical effects:

[0036] The present invention firstly constructs a smart lock unlocking system using the Internet of Things technology, and then designs an Internet of Things-based smart lock unlocking scheme based on the system. In the smart lock unlocking scheme, a new distributed lightweight dynamic authorization management mechanism is designed for the smart key used to open the passive smart lock. The dynamic authorization management mechanism can synchronously issue authorization credentials to a large number of smart key nodes, and the sending of authorization credentials does not require a secure channel, which effectively improves the flexibility and security of authorization credential distribution.
