and step 21, the production and test terminal determines a communication key between the production and test terminal and the Internet of things device through a wireless link between the production and test terminal and the Internet of things device.

In this step, the user needs to establish a wireless link between the production and measurement terminal and the equipment for internet of things, so as to encrypt the interaction information in the communication process between the production and measurement terminal and the equipment for internet of things.

In one implementation, a user starts local area network equipment scanning by triggering a production and test terminal, scanning the last four digits of an MAC (media access control) by using a code scanning gun of the production and test terminal, then searches for a hot spot of an internet of things module of the internet of things equipment, and establishes connection, and at the moment, no configuration information is powered on the internet of things equipment and is in a Soft AP (Soft-AP) mode.

Wherein the wireless link may be a path through a TCP connection.

It should be understood that the production testing terminal supports multi-client linking, that is, multiple internet of things devices can be detected simultaneously, and the embodiment of the present invention is described in detail with one internet of things device.

Optionally, after the wireless link is established, the production and measurement terminal starts to authenticate identity information with the equipment of the Internet of Things, so as to ensure information security during subsequent production of the equipment of the Internet of Things, that is, connection between a Software Development Kit (SDK) for production and measurement of the Internet of Things (IoT) and the equipment of the Internet of Things is not allowed.

In step 21, when interacting with the internet of things device at the production testing terminal side, the following operations are performed:

step 1, sending a first random number generated by a production testing terminal to an Internet of things device.

Wherein the first random number may be a random number 1(4 Bytes).

And step 2, receiving a second random number sent by the Internet of things equipment, the identifier of the Internet of things equipment and a result of whether the Internet of things equipment supports the equipment key.

Optionally, after sending the first random number to the equipment of the internet of things, the equipment of the internet of things generates a second random number, which may be random number 2, and sends the second random number to the production and measurement terminal, and the equipment of the internet of things searches for an identifier of the equipment of the internet of things, determines whether the equipment key is supported, and returns the result to the production and measurement terminal.

And step 3, determining a communication key according to the first random number, the second random number, the identification of the Internet of things equipment and the result of whether the Internet of things equipment supports the equipment key.

In one possible implementation, at initialization, a list of type identities TypeId and device keys DeviceKey is loaded on the production terminal. The list describes the identifiers of the multiple internet of things devices and device keys corresponding to the multiple internet of things devices.

Specifically, according to the identifier of the internet of things device, the device key corresponding to the identifier of the internet of things device is found in the list.

And then, calculating the communication key by using different algorithms according to the first random number, the identifier of the second random number and the result of whether the equipment key is supported by the equipment of the Internet of things.

Specifically, in one possible implementation, if the device key is supported by the internet of things device, the algorithm by which the first signature is generated is implemented as MD5 (random number 2, random number 1, device key).

In addition, in another possible implementation, if the device key is not supported by the internet of things device, the first signature is set to null, that is, the first signature may not exist.

And step 4, sending a first signature encrypted based on the communication key to the Internet of things equipment.

Optionally, after the first signature and the communication key are determined in the above steps, the first signature is encrypted by using the communication key, and after the first signature is encrypted, the first signature is sent to the internet of things device.

In step 4 and in the following processes, the encryption algorithm related to the communication key may be based on a Universal Serial Interface (USS) small-cycle communication encryption algorithm, and the key is the communication key.

Optionally, the second signature is determined at the equipment of the internet of things, and the equipment of the internet of things determines the identity authentication result between the production test terminal and the equipment of the internet of things according to the first signature and the second signature.

In one possible implementation, as for the identity authentication result, after the identity authentication between the production testing terminal and the internet of things equipment passes, the production testing of the internet of things equipment can be normally carried out; when the identity authentication between the production and measurement terminal and the equipment of the Internet of things is not passed, a wireless link between the production and measurement terminal and the equipment of the Internet of things is disconnected; and when identity authentication is not needed between the production testing terminal and the equipment of the Internet of things, responding to the operation of a user, and judging whether to continue production testing on the equipment of the Internet of things or stop production testing on the equipment of the Internet of things.

And step 2, the Internet of things module sends a second random number generated by the Internet of things module, the identification of the Internet of things equipment and a result of whether the Internet of things equipment supports the equipment key to the production and measurement terminal.

The Internet of things module searches the identification of the Internet of things equipment and confirms whether the equipment key is supported or not in the bottom plate.

And 3, the Internet of things module acquires a first signature which is sent by the production and measurement terminal and encrypted based on the communication key.

And step 4, determining a communication key according to the first signature, the first random number and the second random number.

Specifically, if the first signature is not null (that is, the equipment key is supported by the equipment in the internet of things), the module in the internet of things generates a third random number according to the first random number and the second random number, the module in the internet of things sends the third random number to the bottom plate, and the bottom plate determines the communication key according to the third random number and the equipment key.

In one possible implementation, if the device key is supported by the internet of things device, the internet of things module calculates a third random number (e.g., random number 3) according to the first random number and the second random number, and the algorithm is implemented as MD5 (random number 1, random number 2). And then sending a random number 3 to the bottom plate, reversely calculating the random number 3 by the bottom plate to obtain a random number 1 and a random number 2, and then generating a communication key by the bottom plate according to the random number 3 and the equipment key.

In addition, if the first signature is null (that is, the equipment key is not supported by the equipment of the internet of things), the internet of things module determines the communication key according to the first random number and the second random number.

In one possible implementation, if the equipment key is not supported by the internet of things device, the internet of things module calculates the communication key according to the first random number and the second random number, and the algorithm is implemented as MD5 (random number 2, random number 1).

In the process, if the first signature is not empty, the internet of things module generates a fourth random number according to the first random number and the second random number, the internet of things module sends the fourth random number to the bottom plate, then the bottom plate generates a second signature according to the fourth random number, and the bottom plate sends the second signature to the internet of things module; the Internet of things module generates an identity authentication result according to the first signature and the second signature, wherein the identity authentication result comprises any one of the following: and the identity authentication between the production and measurement terminal and the equipment of the Internet of things is passed and the identity authentication between the production and measurement terminal and the equipment of the Internet of things is not passed.

In a possible implementation, if the equipment key is supported by the equipment of the internet of things, the second signature can be obtained through the calculation, and the result of the identity authentication is determined by the module of the internet of things according to the comparison between the first signature and the second signature, namely when the first signature and the second signature are consistent, the identity authentication is passed; when the first signature and the second signature are consistent, the identity authentication is not passed, and the identity authentication result can be that an error code 30004 is returned, and then the wireless link between the terminal and the internet of things device is disconnected.

In addition, if the first signature is empty, the Internet of things module generates an identity authentication result, and the identity authentication result is used for indicating that identity authentication is not needed between the production testing terminal and the Internet of things equipment.

That is, if the equipment key is not supported by the equipment of the internet of things, the next step of the production and measurement terminal and the equipment of the internet of things is referred to the above embodiment without the need of identity authentication.

After step 21, the production test terminal sends a wireless production test request encrypted based on the communication key to the internet of things device.

The wireless production test request is used for requesting the test of the Internet of things equipment.

In this step, the above process already realizes the verification of the identity authentication information between the production test terminal and the equipment in the internet of things and the determination of the communication key, and at this time, the equipment in the internet of things is tested in response to the wireless production test request sent by the production test terminal and encrypted based on the communication key.

Optionally, the internet of things device decrypts the wireless production test request encrypted based on the communication key, notifies the bottom plate to enter a production test mode, and waits for the bottom plate of the internet of things device to reply.

Specifically, the bottom plate enters a wireless production testing mode, and sends a wireless production testing mode response to the Internet of things module.

In addition, if the bottom board refuses to enter the production test mode, the Internet of things equipment responds to an encrypted frame of an application layer error code 0x0001 of the wireless production test request of the production test terminal, keeps the current state of the Internet of things equipment unchanged, and waits for the wireless production test request sent by the production test terminal next time.

It should be understood that: the backplane will enter the production test mode only when the backplane correctly responds to the wireless production test start request, and a time length can be preset as reception timeout, for example, 10 minutes; receiving uplink and downlink frames in a production test mode, and refreshing a receiving overtime timer; except for the production test related command, other commands do not respond; the production test mode cannot be configured; the internet of things device can be always in the AP mode and does not exit.

Further, a first request result of the internet of things device encrypted based on the communication key is received.

The system comprises an Internet of things module, a production test terminal and a wireless production test mode response module, wherein the Internet of things module sends the wireless production test mode response, namely a first request result to the production test terminal, and the first request result is used for indicating that the Internet of things equipment enters the wireless production test mode.

And step 22, after the Internet of things equipment enters the wireless production test mode, the production test terminal sends a production test command encrypted based on the communication key to the Internet of things equipment.

Wherein, the production test command is used for instructing the internet of things device to perform performance test, and the production test command can be a file in uwt format.

And step 23, the equipment of the Internet of things performs performance detection on the equipment of the Internet of things according to the production detection command to obtain a detection result.

Wherein the detection result indicates the performance of the equipment of the Internet of things.

Optionally, the internet of things module sends a package frame, which is packaged after the production test command is decrypted, to the bottom plate, the bottom plate performs production test according to the package frame to obtain a detection result, and the bottom plate sends the detection result to the internet of things module.

Specifically, production test unvarnished transmission data (uplink and downlink for explanation) can be used, a production test terminal sends the data to an internet of things module, the internet of things module decrypts the data, encapsulates the frame again and sends the frame to a bottom plate, the bottom plate replies a confirmation frame, and the bottom plate sends unvarnished transmission data to the internet of things module.

And 24, the Internet of things module sends a detection result encrypted based on the communication key to the production and test terminal.

In this step, the internet of things module encrypts the detection result based on the communication key and sends the detection result to the production and test terminal through the wireless link, so that a user can observe and check the detection result on the production and test terminal and solve possible problems of the detection result, and performance and/or quality of the internet of things equipment are/is improved.

Specifically, in connection with the above example, the internet of things module replies to the confirmation frame, and then encrypts the transparent transmission data and sends the encrypted transparent transmission data to the production and measurement terminal.

Further, after step 24, the equipment of the internet of things sends an exit production test request encrypted based on the communication key to the equipment of the internet of things, and the exit production test request is used for requesting the equipment of the internet of things to exit the production test mode.

The production test quitting request can be responded all the time, if the production test quitting terminal initiatively initiates the production test quitting, and the bottom plate does not respond correctly, the Internet of things module and the bottom plate can not quit the production test mode, so that the bottom plate can normally quit the production test mode.

In the production test mode, the production test terminal does not receive data exiting the wireless production test mode after exceeding a preset time (for example, 10 minutes), the Internet of things equipment sends an exiting production test frame to the bottom plate, and if the bottom plate of the computer plate does not correctly respond, the Internet of things equipment exits the production test mode, so that the logic of the Internet of things equipment is normal, and the exiting production test frame cannot be sent to the production test terminal.

That is, the production test terminal receives a second request result which is returned by the internet of things device and is encrypted based on the communication key, and the second request result is used for indicating that the internet of things device exits the wireless production test mode.

The performance detection method of the internet of things equipment provided by the embodiment of the invention is applied to a production test terminal and the internet of things equipment, a communication key is determined between the production test terminal and the internet of things equipment through a wireless link between the production test terminal and the internet of things equipment, then the production test terminal sends a production test command based on encryption of the communication key to the internet of things equipment after the internet of things equipment enters a wireless production test mode, then the internet of things equipment carries out performance detection, and finally the production test terminal obtains a detection result based on encryption of the communication key sent by the internet of things equipment. In the technical scheme, the production testing terminal is communicated with the Internet of things equipment through the wireless link and performs encryption communication interaction, so that the mode that production testing can be realized only through large-scale wiring and hardware support in the prior art is avoided, and the production testing efficiency is improved.
