Detailed Description
To make the objects, technical solutions and advantages of one or more embodiments of the present disclosure more apparent, the technical solutions of one or more embodiments of the present disclosure will be described in detail and completely with reference to the specific embodiments of the present disclosure and the accompanying drawings. It is to be understood that the embodiments described are only a few embodiments of the present specification, and not all embodiments. All other embodiments that can be derived by a person skilled in the art from the embodiments given herein without making any creative effort fall within the protection scope of one or more embodiments of the present disclosure.
The technical solutions provided by the embodiments of the present description are described in detail below with reference to the accompanying drawings.
In the prior art, a renter is a party who delivers rented objects to a renter for use in a renting contract and obtains earnings. The lessee is the party who uses the leased object in the lease contract and pays the lease money to the lessor according to the contract. In many device rental scenarios, the renter wants to know the operating status and usage of the rented device to prevent the renter from damaging the rented device during usage. However, at present, a renter usually adopts a mode of manually reporting the running state information of the rented equipment by a renter to obtain the running state information of the rented equipment. The operating state information of the leased device acquired based on this way has poor credibility.
Therefore, how to obtain the running state information with high credibility of the leased equipment becomes a technical problem to be solved urgently.
In order to solve the defects in the prior art, the scheme provides the following embodiments:
fig. 1 is a schematic flowchart of an overall scheme of a method for sending operation status information of a leased device according to an embodiment of the present disclosure. As shown in fig. 1:
the renter can provide various rentable equipment such as a computer, a smart phone and the like. A first user (lessee) 101 has a first leased device 103 leased from a lessor and a second user (lessee) 102 has a second leased device 104 leased from a lessor. The first leased device 103 and the second leased device 104 are provided with security systems, so that the first leased device 103 and the second leased device 104 can digitally sign their own operating state information by using a private key stored in their security systems, and upload the digitally signed operating state information to node devices (e.g., the first node device 106, the second node device 107, the third node device 108, etc.) in the block chain network 105.
Next, a method for sending operation status information of a rented device according to an embodiment of the present disclosure will be described in detail with reference to the accompanying drawings:
fig. 2 is a flowchart illustrating a method for sending operation status information of a leased device according to an embodiment of the present specification. From the program perspective, the execution subject of the flow may be the rented device or the program loaded in the rented device.
As shown in fig. 2, the process may include the following steps:
step 202: and acquiring current time information.
In the embodiment of the present specification, a rented device is a device which is rented by a renter from a renter to obtain a use right. The rented device may be various, for example, a computer, a physical server, a cloud server, an industrial production device, a vehicle, etc., which is not particularly limited.
In the embodiment of the present specification, the current time information acquired by the rented device may be information for determining the current time. In practical applications, a clock system may be configured in the leased device so as to obtain the current time information by using the clock system. Or, the rented equipment can also obtain current time information with high accuracy based on the synchronous time service provided by the GPS clock server. In the embodiments of the present specification, the manner of acquiring the current time information is not particularly limited.
Step 204: and if the current time information meets the preset time trigger condition, acquiring the running state information of the rented equipment.
In this embodiment of the present specification, the rented device may determine whether current time information meets a preset time trigger condition, if so, a subsequent reporting process of the operation state information of the rented device may be executed, and if not, the operation state information of the rented device may not be temporarily collected and reported until the preset time trigger condition is met, and then the reporting process of the operation state information of the rented device is executed. Of course, the rented device may also obtain the running state information of the rented device in real time and report the running state information, but this way consumes a large amount of device resources.
Specifically, the rented device may determine whether a time interval between a current time indicated by the current time information and a time at which the operation state information is last reported reaches a set period duration; if so, it may be determined that the current time information satisfies a preset time trigger condition. If not, determining that the current time information does not meet the preset time triggering condition. Therefore, the leased equipment periodically uploads the equipment state information to the blockchain network.
In practical applications, the cycle durations of different setting periods may be the same or different. For example, the set period duration may be set according to the production rule of the tenant, for example, the set period duration may be 1 hour from monday to friday, that is, the running state information of the rented device is reported every 1 hour. On saturday and sunday, the set period duration can be set to 2 hours, that is, the running state information of the rented equipment is reported every 2 hours.
Alternatively, the set period duration for the rented devices rented by the respective lessees may be determined according to the reliability evaluation level of the lessee with respect to the lessee. For example, the set period duration for rented devices rented by a lessee with higher reliability may be set to a larger value, for example, 2 hours. And the set period duration for the rented devices rented by the less reliable lessee may be set to a small value, for example, 1 hour or the like. In the embodiment of the present specification, the setting mode of the set period duration is not specifically limited, and the user may set the setting mode according to actual requirements.
Step 206: digitally signing the operating state information with a private key stored in a security system of the leased device.
In the embodiment of the present specification, a security system may be installed in the rented device. The security system may be implemented by hardware, software, or a combination of hardware and software, which is not particularly limited. For example, the security system may include: secure element SE (secure element), trusted Execution environment TEE (trusted Execution environment), or trusted Execution environment TEE in secure element SE.
The security element SE is usually provided in the form of a chip. To prevent external malicious analysis attacks and to protect data security, an encryption/decryption logic is usually provided in the secure element SE. The trusted execution environment TEE is an execution environment for executing trusted computing, independent of the device operating system. The trusted execution environment TEE in the secure element SE element may then refer to the trusted execution environment deployed within the secure element.
In the embodiment of the present specification, the security system in the rented device has a key generation interface api (application Programming interface). The rented device calls the Key generation interface to enable the Key generation interface to generate a Public Key (Public Key) and a Private Key (Private Key) in a pair, wherein the Private Key can be stored in the security system to be used for digitally signing the running state information of the rented device, and the Public Key can be sent to the target device so that the target device can verify the running state information of the rented device after digital signature.
In this embodiment, step 206 may specifically include: and calling a digital signature interface API of the security system, and sending the running state information of the rented equipment as a parameter to the security system so as to digitally sign the running state information of the rented equipment by using a private key stored in the security system. The running state information after digital signature can be generated in the safety system, so that the reliability is high.
Step 208: and uploading the digitally signed running state information to node equipment in the block chain network.
In the embodiment of the present specification, since the data stored in the blockchain network has the tamper-resistant characteristic, the operation state information of the leased device may be stored to the node device in the blockchain network, so as to ensure the reliability of the operation state information of the leased device.
In practical application, the digitally signed operating state information may be uploaded to the node device in the blockchain network by the security system of the rented device. Alternatively, the security system of the rented device may send the digitally signed running state information to the operating system of the rented device, so as to upload the running state information to the node device in the blockchain network based on the operating system. This is not particularly limited.
In an embodiment of the present specification, a Smart contract (Smart contract) is a computer protocol intended to propagate, verify, or execute contracts in an informational manner. The intelligent contract runs on the block chain network and can automatically execute the protocol according to preset conditions.
Thus, data communication processes between leased devices and the blockchain network may be managed based on intelligent contracts. Specifically, the heartbeat information to be reported by the leased device can be specified through the intelligent contract, and the heartbeat information includes the running state information of the leased device, and the reporting frequency and the storage address of the heartbeat information reported by the leased device are specified through the intelligent contract. The rented equipment can send the running state information after digital signature as heartbeat information to the node equipment of the block chain network for storage according to the intelligent contract.
In this embodiment of the present specification, a node device in the block chain network needs to obtain a public key corresponding to a private key that digitally signs operation state information of a rented device, so that the digitally signed operation state information can be verified by using the public key, and if the verification passes, it can be indicated that the operation state information of the rented device uploaded to the node device in the block chain network is not tampered, and therefore, the node device in the block chain network can store the operation state information of the rented device. If the verification fails, it may indicate that the operation state information of the leased device uploaded to the node device in the blockchain network is tampered, and therefore, the node device in the blockchain network may refuse to store the operation state information of the leased device.
Thus, the method in fig. 2 may further include:
invoking a key generation interface of the security system. Obtaining a public key corresponding to the private key fed back by the key generation interface; the private key is stored within the secure system. And sending the public key to the block chain network so that the node equipment of the block chain network stores the running state information of the rented equipment after the running state information digitally signed by the public key passes verification.
In practical application, the rented equipment can be rented by different users, and after the rented equipment is rented by a new user, the public key and the private key corresponding to the rented equipment can be updated, so that interference between running state information generated when different users rent the equipment is avoided.
Thus, the method in fig. 2 may further include:
invoking a key generation interface of the security system when the rented device is rented by a new user.
Acquiring a new public key fed back by the key generation interface; a private key corresponding to the new public key is stored within the secure system, and the private key corresponding to the new public key can be used to digitally sign current operating state information of the leased device.
And sending the new public key to the block chain network so that the node equipment of the block chain network verifies the running state information digitally signed by using the private key corresponding to the new public key by using the new public key, and stores the running state information after the verification is passed, thereby ensuring that the running state information stored in the rented equipment of the block chain network is not tampered.
In practical application, when the number of node devices in the blockchain network is smaller than a threshold value, the rented device may send the digitally signed operation state information to each node device in the blockchain network, so as to quickly store the digitally signed operation state information at each node device in the blockchain network. When the number of the node devices in the blockchain network is greater than or equal to the threshold, the rented device may send the digitally signed operation state information to only some of the node devices in the blockchain network, and based on the blockchain consensus mechanism, the remaining node devices may obtain the digitally signed operation state information from other node devices, so as to reduce resource consumption of the rented device.
It should be understood that the order of some steps in the method described in one or more embodiments of the present disclosure may be interchanged according to actual needs, or some steps may be omitted or deleted.
The method of fig. 2 digitally signs the operating status information of a leased device by using a private key in the secure system of the leased device; and uploading the digitally signed running state information to node equipment in the block chain network, so that the node equipment in the block chain network verifies the digitally signed running state information by using a public key corresponding to the private key and then stores the running state information. Therefore, the running state information uploaded to the node equipment in the block chain network can be guaranteed not to be tampered in the uploading process and the storing process, and high reliability of the running state information of the rented equipment acquired from the block chain network subsequently can be guaranteed.
Based on the method of fig. 2, the present specification also provides some specific embodiments of the method, which are described below.

And part of the devices have application process limitations, for example, CPU overload operation is not allowed, and therefore load information of the devices needs to be monitored.

In practical application, the obtained running state information of the rented equipment can be used as data for quantitatively analyzing the operating conditions of the renter and the lessee. For example, determining that the usage rate of the device is greater than the threshold value based on the operating status information of the rented device may indicate that the operation of the renter is stable, or may indicate that the renter actually rents the rented device without counterfeiting. Therefore, new dimension data with high reliability are provided for the third-party enterprise to analyze the operation conditions of the renters and the lessees.
The obtaining of the location information of the rented device may specifically include:
reading the network address of the leased device through a specific interface of the network card of the leased device so as to determine the location information of the leased device based on the network address.
