Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It should be noted that the remote testing method, device and system disclosed in the present application can be used in the technical field of testing safety, and can also be used in any field except the technical field of testing safety.

The remote testing method, device and system provided by the invention are described in detail below with reference to the accompanying drawings.

Near Field Communication (NFC for short) is an emerging technology, devices (such as mobile phones) using the NFC technology can exchange data when they are close to each other, and is integrated and evolved from a non-contact Radio Frequency Identification (RFID) and an interconnection technology, and by integrating functions of an induction card reader, an induction card and point-to-point Communication on a single chip, applications such as mobile payment, electronic ticketing, door access, mobile identity identification, anti-counterfeiting and the like are realized by using a mobile terminal.

It can be understood that data interaction between the NFC entity devices is near field communication, and for two NFC entity devices, a relay device is required to implement communication. In a specific embodiment of the present invention, two NFC entity devices that need remote communication are referred to as a first NFC entity device and a second NFC entity device, respectively. For example, in a scenario of mobile phone non-contact payment, the first NFC entity device is a pos machine and is configured to initiate a payment request, and the second NFC entity device is a mobile phone and responds to the payment request. If the pos machine and the mobile phone are in a near field, the NFC chip in the pos machine and the mobile phone can enable the pos machine and the mobile phone to directly communicate. If the pos machine and the mobile phone are in two different places and are in far fields, two relay devices need to be used, wherein the first NFC relay device corresponds to the first NFC entity device, and the pos machine and the mobile phone are in near fields, so that NFC direct communication can be realized; and the second NFC relay device corresponds to the second NFC entity device, and the second NFC relay device and the second NFC entity device are positioned in the near field, so that NFC direct communication can be realized. The first NFC relay device and the second NFC relay device may communicate via a wired or wireless network, for example, a wired network is a cable, and a wireless network is wifi or the like.

In a specific embodiment, the present application provides a remote testing method, where the method is applied to a first NFC relay device, as shown in fig. 1, and includes:

s1, receiving a tested signal transmitted by the first NFC entity device;

specifically, the first NFC entity device is an NFC-enabled device, which can actively send out a test signal to be tested. In a specific embodiment, the first NFC physical device may be a pos device, an access control device, or the like. For example, the first NFC physical device is a pos machine, and when an amount to be paid is input by pressing a keyboard, the pos machine generates a data packet according to the NFC related protocol, where the data packet is a signal to be tested and includes the amount to be paid. The first NFC entity device sends the generated signal to be tested to the first NFC relay device in an NFC mode, so that the first NFC relay device receives the signal to be tested.

S2, transmitting the tested signal to a second NFC relay device located at a far end, so that the second NFC relay device receives the tested signal and generates a response signal;

specifically, the first NFC relay device and the second NFC relay device are two devices in a remote state, so that communication between the two devices needs to be through a wired or wireless remote communication network. In a specific embodiment, the remote communication network may be a cable-based communication network or a wifi communication network. In order to ensure the security of the measured signal data, two ways are available, one is to build a private communication network of a first NFC relay device and a second NFC relay device, so that only two relay devices exist in the private communication network, and other devices cannot use or access the network, so that the measured signal may not be encrypted, and certainly, the measured signal may also be encrypted; and the other is that the first NFC relay device encrypts the transmitted measured signal and transmits the encrypted measured signal to the second NFC relay device through a public communication network, and the second NFC relay device decrypts the encrypted measured signal which is received in accordance with the second NFC relay device to obtain the measured signal. For the first, the requirements for its implementation are complex; the second method is a commonly used method for ensuring data security. For the second method, as shown in fig. 2, the specific steps are as follows:

s21, encrypting the tested signal to obtain the cipher text information of the tested signal;

in a specific embodiment, for example, in a non-payment application scenario of a mobile phone, a pos approaches a first NFC relay device after inputting a money amount, the pos generates a signal to be tested such as 00a404000E325041592E5359532E 44444446303100 through an NFC module, an NFC communication module of the first NFC relay device receives the signal and converts the signal into digital information, the digital information is sent to a central processing unit of the pos, the central processing unit transfers the digital information to an nfcc scolet program to complement the data 00a404000E325041592E5359532E 4446303100 with a preset number of 0, for example, 160 s in 000000000000, and then a key 12345678901234567890123456789012 is used for 3des ECB (word codebook) mode encryption, and the encryption is performed to obtain ciphertext information of the signal to be tested for each 8-byte group. If the number of bytes is less than a predetermined number, for example, 8 bytes, the encryption is not performed.

And S22, transmitting the tested signal ciphertext information to a second NFC relay device located at a far end, so that the second NFC relay device receives the tested signal ciphertext information and generates a response signal.

Specifically, the measured signal ciphertext information is transmitted to the second NFC relay device located at the far end through a cable network or a wifi network. In a specific embodiment, if a cable network is adopted, measured signal ciphertext information is modulated into an electric signal through a modem and loaded onto a cable, and the cable transmits the signal; if the wifi network is adopted, the signals are directly transmitted to the internet through the wifi module and transmitted. On the other hand, the second NFC relay device receives the cipher text information of the signal to be tested and generates a response signal. In a specific embodiment, after receiving the ciphertext of the signal to be tested, the second NFC relay device decrypts the ciphertext of the signal to be tested, first performs decryption in a 3des ECB mode with the key 12345678901234567890123456789012, and then removes the 16 th bit to obtain the decrypted signal to be tested. And sending the decrypted tested signal to a mobile phone through an NFC module, responding a payment request in the tested signal by the mobile phone to generate a response signal, and transmitting the response signal to second relay equipment. And the second NFC relay device transmits the response signal to the first NFC relay device through the remote network. In a specific embodiment, the second NFC relay device may encrypt the response signal and then transmit the response signal.

And S3, receiving the response signal, and further determining that the first NFC entity device is in a normal state according to the transmission condition of the detected signal and the response signal.

Specifically, after receiving a response signal transmitted by the second NFC relay device, the first NFC relay device sends the response signal to the first NFC entity device, and then may determine that the first NFC entity device is in a normal state according to the transmission conditions of the detected signal and the response signal. It can be understood that, if the received response signal is an encrypted signal, the encrypted response signal needs to be decrypted first, and the encrypted response signal is decrypted first in the 3des ECB mode with the key 12345678901234567890123456789012, and then the 16 bits are removed to obtain a decrypted response signal, and then the response signal is sent to the first NFC entity device. And if the first NFC entity device finishes the service operation according to the detected signal and the response signal, determining that the first NFC entity device is in a normal state, and if the first NFC entity device does not finish the service operation, determining that the first NFC entity device is in an abnormal state and further debugging is needed.

It is understood that the first NFC relay device may perform the above steps to include a measured signal receiving module, a measured signal transmitting module, and a response signal receiving module, where the measured signal receiving module performs step S1, the measured signal transmitting module performs step S2, and the response signal receiving module performs step S3, and subsequent related embodiments are not repeated.

On the other hand, in a specific embodiment, the present application provides a remote testing method, which is applied to a second NFC relay device, as shown in fig. 3, and includes:

s01, receiving a detected signal transmitted by a first NFC relay device at a far end;

specifically, the second NFC relay device receives the measured signal transmitted by the first NFC relay device located at the remote end through a remote network, such as a cable or wifi. If the signal is encrypted, the signal needs to be decrypted.

S02, transmitting the tested signal to a second NFC entity device;

specifically, the second NFC relay device and the second NFC entity device are in the near field, so that direct communication can be performed through the NFC function. And the second NFC relay equipment sends the unencrypted signal to be detected to the second NFC entity equipment. In a specific embodiment, for example, in a non-payment scenario of a mobile phone, that is, when the NFC relay device is close to the mobile phone, the measured signal is transmitted to the mobile phone end by the relay device.

And S03, receiving the response signal transmitted by the second NFC entity device, transmitting the response signal to the first NFC relay device at the far end, and determining that the second NFC entity device is in a normal state according to the transmission conditions of the detected signal and the response signal.

Specifically, when the second NFC entity device responds to the content in the signal to be detected and generates a response signal, the response signal is sent to the second NFC relay device. And the second NFC relay equipment receives the response signal transmitted by the second NFC entity equipment and transmits the response signal to the first NFC relay equipment at the far end. In a specific embodiment, for example, the mobile phone does not receive payment, the second NFC entity device is a mobile phone, and generates a corresponding response signal according to the payment request in the detected signal, if payment is available, payment is not available, balance is insufficient, and the like, and then sends the generated response signal to the second NFC relay device through the NFC function. After receiving the response signal, the second NFC relay device may directly send the response signal through the private network; the response signal may be encrypted and transmitted via the shared network. In a specific embodiment, the NFC communication module in the second NFC entity device receives the signal, converts the signal into digital information, sends the digital information to the central processing unit, and the central processing unit transfers the digital information to the nfcshook program to complement the data with a preset number of 0, for example, 0000000000000000, for 160 s, and then encrypts the data in 3des ECB mode with the key 12345678901234567890123456789012 to obtain ciphertext information of the response signal in every 8-byte group. If the number of bytes is less than a predetermined number, for example, 8 bytes, the encryption is not performed. And then the second NFC relay device transmits the ciphertext information of the response signal to the first NFC relay device through a wired or wireless shared network, so that the first NFC relay device sends the response signal to the first NFC entity device, and then the second NFC entity device can be determined to be in a normal state according to the transmission conditions of the detected signal and the response signal, if the first NFC entity device completes the business operation, the second NFC entity device can be determined to be in the normal state according to the transmission conditions of the detected signal and the response signal, and if the first NFC entity device does not complete the business operation, further debugging is needed.

In a specific embodiment, the overall system is integrated to obtain a remote testing method, as shown in fig. 4, which includes:

s101, a first NFC relay device receives a detected signal transmitted by a first NFC entity device and transmits the detected signal to a second NFC relay device located at a far end, so that the second NFC relay device receives the detected signal and transmits the detected signal to the second entity device;

s102, receiving a response signal transmitted by second NFC entity equipment by second NFC relay equipment, and transmitting the response signal to first NFC relay equipment so that the first NFC relay equipment receives the response signal and transmits the response signal to the first NFC entity equipment;

and S103, determining that the first NFC entity device and/or the second NFC entity device are in a normal state according to the transmission condition of the detected signal and the response signal.

In a specific embodiment, data interaction between the NFC entity devices is near field communication, and for two NFC entity devices, a relay device is required to implement communication. In a specific embodiment of the present invention, two NFC entity devices that need remote communication are referred to as a first NFC entity device and a second NFC entity device, respectively. For example, in a scenario of mobile phone non-contact payment, the first NFC entity device is a pos machine and is configured to initiate a payment request, and the second NFC entity device is a mobile phone and responds to the payment request. If the pos machine and the mobile phone are in a near field, the NFC chip in the pos machine and the mobile phone can enable the pos machine and the mobile phone to directly communicate. If the pos machine and the mobile phone are in two different places and are in far fields, two relay devices need to be used, wherein the first NFC relay device corresponds to the first NFC entity device, and the pos machine and the mobile phone are in near fields, so that NFC direct communication can be realized; and the second NFC relay device corresponds to the second NFC entity device, and the second NFC relay device and the second NFC entity device are positioned in the near field, so that NFC direct communication can be realized.

In order to ensure the security of the measured signal data, two ways are available, one is to build a private communication network of a first NFC relay device and a second NFC relay device, so that only two relay devices exist in the private communication network, and other devices cannot use or access the network, so that the measured signal may not be encrypted, and certainly, the measured signal may also be encrypted; and the other is that the first NFC relay device encrypts the transmitted measured signal and transmits the encrypted measured signal to the second NFC relay device through a public communication network, and the second NFC relay device decrypts the encrypted measured signal which is received in accordance with the second NFC relay device to obtain the measured signal. For the first, the requirements for its implementation are complex; the second method is a commonly used method for ensuring data security. For the second method, the specific steps are as follows:

On the other hand, in a specific embodiment, the second NFC relay device is configured to perform the following steps:
