Detailed Description
The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
Fig. 1 is a flowchart of a configuration method of an intelligent lock according to an embodiment of the present invention.
As shown in fig. 1, in this embodiment, the present invention provides a configuration method of an intelligent lock, including:
s12: generating a first private key and a corresponding first public key; wherein the first private key cannot be derived;
s14: storing the corresponding relation between the first public key and the current intelligent lock into an intelligent lock contract on the block chain;
s16: and storing the authorization relationship between the current intelligent lock and the second public key of the administrator into an intelligent lock contract, so that the terminal of the administrator generates an authorization transaction comprising a third public key of the first user and the intelligent lock information according to the second private key signature corresponding to the second public key and sends the authorization transaction to the block chain node for execution through the intelligent lock contract, and storing the authorization relationship between the current intelligent lock and the first user into the intelligent lock contract after the identity of the administrator is verified successfully.
Wherein the smart lock information includes at least one of: the first public key is the equipment information of the current intelligent lock; the corresponding relation and the authorization relation are used for verifying whether a user requesting to unlock the current intelligent lock is authorized.
Specifically, the intelligent lock configuration method provided by the embodiment is suitable for unshared equipment, and can be configured for private use scenes such as private door locks and cabinet locks, and can also be configured for commercial scenes such as hotel and hotel door locks.
Taking the initialization configuration of the private door lock as an example:
in the step S12, in step S12,automatic generation of first private key p incapable of being exported inside intelligent lock1And with p1Corresponding, public first public key P1。
Wherein the first private key p1And a first public key P1The smart lock can be generated by an encryption sim card chip built in the smart lock, and can also be generated by an encryption processor chip. Preferably, a first private key p is generated1The chip is also provided with hardware protection, and can be self-destroyed to ensure the first private key p when being cracked violently1And is not stolen.
In step S14, the smart lock passes through the first private key p1The signature generation comprises a first public key P1And device information LID of the current smart lock1To tx1, sends tx1 to the blockchain node.
The block chain node receives, broadcasts, packages and executes tx1 through intelligent lock contract, registers the current intelligent lock in the contract, and stores the corresponding relation (LID) between the current intelligent lock and the first public key1-P1)。
Preferably, in order to prevent the counterfeit smart lock from being registered in the smart lock contract as well, the first public key may be stored in the smart lock contract at the time of the factory shipment of the smart lock, so that the smart lock performs signature verification at the time of executing the first registration transaction tx1, thereby preventing the registration transaction sent by the counterfeit smart lock from being successfully executed.
In another embodiment, step S14 may be further configured to output the first public key P to the management device with the registered lock authority when the smart lock is shipped from the factory1And device information LID of the current smart lock1For the management equipment to produce P1And LID1To tx2, sends tx2 to the blockchain node. The blockchain node registers the current intelligent lock in the contract and stores the corresponding relation (LID) between the current intelligent lock and the first public key through the intelligent lock contract execution tx21-P1)。
In step S16, the smart lock obtains the second public key P of the current user (administrator)2Then, by the first private key p1Signature generation manager authorizes transaction tx3 and sends to tileAnd (4) linking the nodes.
Block chain nodes receive, broadcast, package, and execute tx3 through smart lock contract, through P1After the signature of tx3 is successfully verified, the current smart Lock (LID) is stored in the contract1) Administrator's public key P2。
After the administrator configuration is completed, the current user (administrator) can use the second private key p2And authorizing the family. For example, the user terminal of the current user passes through the second private key p2Signature Generation of a third public Key P comprising family members3And the first public key P of the current intelligent lock1And sends the authorized transaction tx4 to the blockchain node; block chain nodes receive, broadcast, package, and execute tx4 through smart lock contract, through P2After the signature of tx4 is successfully verified, the current smart Lock (LID) is stored in the contract1) Is authorized to the public key P of the user3。
When a user requests to unlock the current intelligent lock, the current intelligent lock can inquire the authorization relationship stored in the intelligent lock contract to verify whether the unlocking request is legal or not.
It should be noted that, the smart lock contract may configure the administrator as authorized or unauthorized according to actual requirements, for example, when the smart lock is applied in a private use scenario, the administrator may be configured as authorized (having an unlocking right), and then the administrator does not need to authorize itself any more; when the intelligent lock is applied to commercial scenes such as hotel door locks, an administrator can be configured to be unauthorized (without unlocking permission), and if the administrator needs the unlocking permission, the administrator needs authorization as a common user.
In a preferred embodiment, the authorized transaction further includes a validity period of the authorized relationship, and the smart lock contract is further configured to store the validity period of the authorized relationship.
For example, in any scenario, an administrator may temporarily authorize guests, and for example, in a business scenario, an administrator may authorize customers, clients, etc. for different objects on a short-term basis, depending on business needs.
