Description

Internet of things pairing method and device, base station and storage medium

Technical Field

The invention relates to the field of communication of the Internet of things, in particular to a pairing method, a pairing device, a base station and a storage medium of the Internet of things.

Background

With the development of the internet of things and the industrial internet, new technology which is continuously emerging prompts the intelligent equipment to greatly facilitate the daily life of people. More and more industries are beginning to improve the convenience of device usage in daily life by setting up applications that are combined with smart devices.

The commonly used method for realizing pairing of the internet of things at present comprises the following steps:

1 techniques based on wireless channels

The radio frequency identification technology RFID (radio frequency identification) is a technology for performing non-contact data communication by using a radio signal, and realizes identification of a specific target and data reading and writing by combining wireless communication with a data access technology. In the process of object identification, the reading, writing and communication of the electronic tag by the device are realized in the form of electromagnetic waves, and physical or optical contact between an identification system and a specific object is not needed. Conventional RFID systems consist of three parts: readers, electronic tags (transponders) and application software systems. The working principle of the RFID system is as follows: firstly, a reader activates a transponder in a mode of transmitting radio waves with preset frequency to the transponder, after energy is transmitted to the transponder, the transponder starts a driving circuit to transmit identification information stored in the transponder to the outside, the reader receives and decodes data of the transponder in sequence, and finally the data are sent to an application program to be correspondingly processed.

NFC (near field communication) is an improved technology for RFID, and is also a short-distance high-frequency near field wireless communication technology, and the main difference with RFID is that point-to-point communication is added. For RFID the relationship between the reader and the transponder is a master-slave relationship, whereas for NFC the two are peer-to-peer relationships, and the devices can find each other and establish a communication connection. Therefore, the RFID is mainly applied to logistics, asset management, production and tracking, and the NFC is applied to the fields of public transport, mobile payment, entrance guard and the like.

Other wireless channel technologies such as Wi-Fi, bluetooth and ZigBee have longer communication distances than NFC, but users still face the risk of being eavesdropped without knowing.

2 Acoustic based techniques

The acoustic-based technique refers to generating a key by sound. The principle is that according to the background sound of the position of the equipment, a secret key is obtained from frequency domain information, and pairing is completed through fast Fourier transform. Dhwani further uses the sound signal to emulate hardware NFC to achieve the goal of near field communication. The microphone and the loudspeaker are used for realizing the secure communication pairing of the mobile phone under the near field condition, and the requirement on any special NFC hardware is eliminated. However, the limitations of microphones result in inconsistent and less secure communication information. In order to improve the security, the sampling time needs to be prolonged, and the matching difficulty is increased.

Compared with the traditional network communication, the communication between the Internet of things devices sends information through a public channel, and the risk of interception and tampering by a third party exists. In order to avoid the risk that information is intercepted and cracked in the transmission process and ensure the safety and the confidentiality of information transmission, a wireless network communication protocol needs to encrypt the information before transmitting the information; meanwhile, in order to ensure the reliability of data transmission, it is necessary to prevent information from being interfered by an external signal source during transmission. How to realize safe and stable information transmission becomes a challenge without influencing the life convenience of people.

Example one

Fig. 1 is a flowchart of an internet of things pairing method according to an embodiment of the present invention, where the embodiment is applicable to a base station capable of implementing internet of things pairing, and the method specifically includes the following steps:

s110, broadcasting a key request at a first frequency, wherein the key request comprises base station identity information.

In this embodiment, the base station continuously broadcasts the key request when the base station does not establish the communication connection with the transponder, the key request is used to activate the transponder within the effective communication range of the base station, the key request can be received by all transponders within the effective communication range of the base station, but only a specific transponder will establish the communication connection with the base station, where the first frequency is a broadcast frequency in a state of maintaining low power consumption of the base station. Broadcasting key requests at a first frequency aims at reducing base station energy consumption. The base station identity information is a base station id (identity document), which may be a unique code or other identifier representing the identity of the base station, so that the responder can identify different base stations to realize communication with the specified base station.

Optionally, in some embodiments, step S110 includes steps S111-113 (not shown):

s111, judging whether a responder which is already in communication connection with the base station exists in the communication range of the base station.

And S112, if so, stopping broadcasting the key request.

And S113, if not, periodically broadcasting the key request outwards at the first frequency.

Considering that in the case that the base station has established a communication connection with the responder within the communication range of the base station, there is no need to broadcast the key request and perform data reception and analysis, and in this case, in order to reduce unnecessary energy consumption and achieve the function of energy protection, in an alternative embodiment, the base station stops broadcasting the key request when the base station has established a communication connection with the responder, and the base station is normally maintained in a servo state, which means that the base station operates in a low energy consumption state. In the above embodiment, in order to avoid activating the subsequent pairing process due to the key request of the unpaired base station after the responder enters the communication area of the unpaired base station, the key request broadcast by the base station includes the base station identity information (ID information), which is intended to provide an identification mark for the responder, thereby avoiding energy waste and key leakage caused by frequent unnecessary activation of the responder.

And S120, receiving vibration data returned by the responder based on the key request at a second frequency, wherein the second frequency is greater than the first frequency, and the vibration data is generated by the responder after the identity information of the base station passes verification.

After receiving the key request sent by the base station, the responder returns vibration data after verifying that the base station sending the key request is the appointed pairing base station, specifically, whether the base station sending the key request is the appointed pairing base station is verified according to the identity information of the base station, if so, the verification is passed, otherwise, the verification is not passed. The base station can detect whether the responder returns vibration data or not before completing pairing with the responder, the base station can enter a high-frequency data sampling state when receiving the vibration data, the base station performs high-frequency sampling on the vibration data at the moment, full-range high-frequency vibration data acquisition is performed in a vibration time period when the vibration is sensed, and after the responder stops returning the vibration data, the base station cannot sense the vibration and then recovers a servo state to listen to the vibration at a low frequency. The second frequency is a sampling frequency after a base station enters a high-frequency data sampling state, and the second frequency is greater than the first frequency.

Optionally, in some embodiments, step S120 includes S121-122 (not shown):

and S121, detecting whether vibration data reaching a preset threshold exists in the communication range in a low-frequency mode.

And S122, if so, receiving the vibration data at a second frequency, converting the vibration data into vibration data by the responder according to a preset encoding algorithm and a preset key, and returning the vibration data in a mechanical vibration mode.

The low-frequency mode is a mode that the base station monitors vibration in a low power consumption state, the base station cannot always collect vibration data in order to reduce energy consumption, and because the sampling frequency is far higher than the monitoring frequency, the energy consumption is higher, so that the vibration data can be collected at the second frequency (sampling frequency) only when the vibration data returned by the responder is detected.

And S130, analyzing the vibration data to obtain a preset key.

After the base station receives all the vibration data, the vibration data in this embodiment cannot be directly used as a secret key, and the vibration data needs to be processed and analyzed, specifically, the vibration data is restored to a preset secret key according to a preset analysis algorithm.

And S140, establishing communication connection with the responder by using the preset key.

After the preset key is obtained through analysis, the base station performs subsequent arrangement according to the validity of the preset key, specifically: and matching the preset secret key with a standard secret key stored in the base station, if the preset secret key is not in accordance with the standard secret key, the preset secret key is invalid, the base station stops receiving the vibration data and enters a servo state, if the preset secret key is in accordance with the standard secret key, the base station starts to establish a link with the responder, and the base station and the responder are established to be in communication connection to complete pairing.

In the technical scheme of the embodiment of the invention, the base station broadcasts the key request at the first frequency to activate the responder, receives the vibration data returned by the responder at the second frequency which is higher than the first frequency, and analyzes the vibration data to obtain the preset key to establish communication connection with the responder.

Example two

The embodiment is further optimized based on the above embodiments, and for example, the process of analyzing the vibration data is further explained, which includes the following specific contents:

in this embodiment, the base station senses the vibration condition around based on the acceleration sensor, that is, collects vibration data through the acceleration sensor. In the process of detecting whether vibration data reaching a preset threshold exist in the communication range in a low-frequency mode, adopting an SVM threshold detection method: in the detection process, the spatial direction of the acceleration is ignored, the vector sum operation is carried out on the spatial acceleration, the resultant acceleration V is calculated through the vector sum of the three-axis acceleration, and the resultant acceleration V is compared with a preset threshold value to judge whether the vibration occurs. If the combined acceleration V of the three values of the sensor reaches a preset threshold value, the vibration can be preliminarily judged and the vibration data can be received. The resultant acceleration V based on the SVM is calculated as follows:

wherein x, y and z respectively represent acceleration values on three coordinate axes.

The vibration data generation is transmitted by a vibration motor on the transponder, which transmits the vibration data in the form of vibrations to the surroundings by means of different vibration durations, vibration intensities and vibration frequencies. The motion of acceleration along three orthogonal axes in the presence of vibration can convert the data into a three-dimensional data set (X, Y, Z), in which gravitational acceleration represents a constant offset along an axis directed toward the floor. According to the embodiment, the preset key for transmitting the vibration data depends on the length of the vibration time, different vibration times represent different key elements, and the deviation direction of vibration in the physical direction is not considered, so that the system ignores the spatial direction of acceleration in the process of extracting the vibration characteristics from the data monitored by the acceleration sensor.

More specifically, as shown in FIG. 2, step S130 includes steps S131-133:

s131, analyzing the single character of the vibration data through a key character analysis algorithm, and determining character information corresponding to the vibration data.

In this embodiment, the single character in the vibration data is analyzed to ensure accurate determination and completeness of the analyzed character string, and after each character is accurately analyzed, complete character information of the preset key is obtained.

S132, analyzing the time interval of the character string from the vibration data by using a key character string start time determination algorithm.

On one hand, different from wireless transmission, only the start time and the end time of character string transmission need to be confirmed, and in the vibration data transmission process, the corresponding start time and end time need to be confirmed for each key unit in the preset key, so that the preset key can be accurately analyzed. On the other hand, the transponder starts transmission upon receiving a key request sent by the base station. In order to ensure the success rate of transmission and the accuracy of received data, the transponder usually performs more than one data transmission, and the base station needs to have the capability of separating out the correct secret key from the vibration data and starting matching after obtaining the vibration data. How to obtain the correct pre-key from the continuous vibration requires a mechanism to be set up to confirm. The time interval for analyzing the character string is to analyze the starting time and the ending time of intercepting the character string data in the vibration data, avoid the occurrence of string codes in the obtained preset key, and ensure that the obtained preset key is complete and has no error in sequence.

And S133, determining a preset key corresponding to the vibration data according to the character information and the time interval.

More specifically, the time interval for parsing the character string in step S132 corresponds to the mechanism adopted by the vibration data transmission process of the transponder, and is illustrated here by two examples:

the first is a vibration interval based detection mechanism. The base station starts collecting vibration data and extracting the key from the vibration data when the vibration is detected. Under the mechanism, as long as the base station detects that vibration data is generated, the secret key is supposed to start to be transmitted, the sampling frequency is increased, and the vibration data is started to be collected and the secret key is analyzed. The method is simple to operate and easy to realize. However, the key transmitted by the transponder is easily determined as an invalid key by misidentification of the base station, resulting in a failure of the authentication. According to the VibKey (Vibration-based Key Generation and Communication) transmission mechanism, after the responder enters the Communication range of the base station and receives a Key request sent by the base station, the responder starts to transmit the preset Key in a Vibration mode. To ensure the integrity and accuracy of the delivery of the preset keys, the transponder must continuously transmit multiple sets of preset keys. When the transponder contacts the base station, the preset key is not normally transferred from the first character, so the base station will easily generate an erroneous string code by decoding the key only by recording the continuous vibration data. For example, the transponder passes two sets of preset keys 213 and 213. Since the base station starts receiving vibration data from the second digit in the first set, the base station may misidentify the pre-key as 132.

This problem can be achieved by setting the key transmission interval. In general, there are three ways to set the transmission time interval: in the first mode, the key interval is the interval time between the end time of the first transmission and the start time of the second transmission, and is used for facilitating the base station to intercept the key character string; in the second mode, the key interval is the time interval between the characters in the same group of key strings, and is used for clarifying the starting time and the ending time of a single character, so that each individual character contained in the character can be distinguished conveniently; in a third mode, the key interval is the transmission interval time between adjacent bits of each key character after being encoded by the binary encoding mechanism, and is used for determining the starting time and the ending time of each binary encoding in the vibration data of the single character. The three key interval time relations are as follows: the interval time between the key character strings is longest, the interval time between the characters in the key character strings is next to the longest, and the time interval between the binary coding numbers corresponding to each character after the binary coding is carried out on the key is shortest. That is, the vibration data generated by the transponder is determined from the vibration data, from which three vibration intervals are determined: the key structure comprises a first vibration interval (interval time between key strings), a second vibration interval (interval time between characters in the key strings) and a third vibration interval (time between each character and a binary encoding code after binary encoding of the key) the first vibration interval is larger than the second vibration interval, the second vibration interval is larger than the third vibration interval, the first vibration interval corresponds to the character string interval, the second vibration interval corresponds to the character interval, and the third vibration interval corresponds to the binary encoding bit interval of each character.

The second is a start time identifier based detection mechanism. The starting time and the ending time of the key transmission are represented by setting a special transmission vibration mode. Before the preset secret key is transmitted, setting a special vibration (initial transmission vibration symbol) to indicate that the next transmitted data is the vibration data of the preset secret key to the base station module; and setting an end vibration symbol after the key transmission is finished to inform the base station that the vibration data of the preset key is transmitted completely. Compared with the detection mechanism based on the vibration time interval, the detection mechanism based on the start time identifier needs to perform additional vibration mode representation before each transmission unit starts transmission and after the transmission is finished, the transmission complexity is high, the system energy consumption is high, and the risk of intercepting the vibration data is increased. Therefore, VibKey preferentially selects a mechanism based on vibration intervals to realize key coding and transmission of a responder end and key analysis of a base station end. Namely, a first pass vibration symbol and an end vibration symbol are identified based on the vibration data, the first pass vibration symbol is used for determining a vibration data starting point corresponding to the character string of the preset key, and the end vibration symbol is used for determining a vibration data ending point corresponding to the character string of the preset key.

Optionally, in some embodiments, as shown in fig. 3, after step S130, the method further includes:

s150, sending a vibration stopping request to the responder, wherein the vibration stopping request is used for informing the responder to stop sending vibration data and comprises base station identity information.

After the complete preset key is obtained based on the vibration data, no matter whether the preset key is consistent with the standard key of the base station or not, the base station sends a vibration stopping request to the responder to inform the responder to stop transmitting vibration data so as to reduce energy consumption, and meanwhile, in order to not influence the normal work of other responders, the vibration stopping request sent by the base station also comprises base station identity information which is used for the responder to verify whether the base station sending the vibration stopping request is the base station receiving the vibration data of the responder.

According to the technical scheme of the embodiment of the invention, a specific mode for detecting whether the vibration data appears or not according to the preset threshold value and a specific mode for analyzing the time interval of the character string are provided, so that the completeness and the accuracy of obtaining the vibration data and analyzing to obtain the preset key are further ensured.

EXAMPLE III

Fig. 4 is a schematic diagram of a pairing method of the internet of things according to a third embodiment of the present invention, where the present embodiment is applicable to a transponder capable of implementing pairing of the internet of things, and the method specifically includes the following steps:

s310, receiving a key request sent by a base station, wherein the key request comprises base station identity information, and verifying whether the base station is a matched base station or not according to the base station identity information.

The responder is responsible for receiving a key request sent by a base station and transmitting a preset key carried by the responder to a specified base station in a vibration mode to complete pairing, before the key request sent by the base station is not received, the responder is in a servo state, the responder is maintained to operate in a low-power state, wireless data information (such as the key request) around the responder is periodically intercepted, after the key request is intercepted, whether the key request is sent by the specified base station needs to be verified, namely whether the base station corresponding to the key request is the specified base station is verified according to the identity information of the base station in the key request, if so, the key request is responded, and if not, the key request is not responded (the servo state is maintained).

And S320, if so, converting the preset key into vibration data.

After the key request received by the responder is verified to be sent by the appointed pairing base station, the responder can convert the preset key stored in the responder into vibration data according to the preset coding algorithm, so that the conversion from characters to a vibration mode digital sequence is realized. In the process, the character string of the key is expressed into a key character string array according to a preset encoding algorithm. In order to facilitate the effective recognition of the character codes in the preset key by the base station after transmission, the process also comprises a mechanism for processing the starting time and the ending time of the character string of the key, and the position of the character string in the data stream can be effectively marked.

S330, transmitting the vibration data to the base station in a mechanical vibration mode.

After the vibration data is obtained, the transponder realizes data stream transmission of the key through mechanical vibration of the vibration motor, and due to the limitation of the intelligent device on the vibration mechanical motor, preferably, the vibration data transmission can be performed in a time-sharing mode.

More specifically, in some embodiments, the process of converting the preset key into the vibration data, that is, the encoding process according to the preset encoding algorithm and the preset key, may be implemented in two ways, including:

the time-based encoding mechanism represents different characters by vibrating for different vibration time lengths for characters in the preset key, for example, a character string to be transmitted is encoded by the corresponding time length of each character, vibrating for 1 second continuously represents the number 1, vibrating for 2 seconds continuously represents the number 2, and so on. The coding mechanism has the advantages that the coding is simple, the characters in the preset key only need to vibrate in equal length according to the numerical value, and the key identification accuracy is high because each character corresponds to a continuous vibration time period. Its disadvantages are slow transmission speed and high energy consumption.

A binary-based encoding mechanism sets a password according to a binary code, encoding each character in a binary manner. The method has the advantages that the average length of a single secret key is short, and the energy consumption is low; the method has the disadvantages that each character is represented by a plurality of binary systems, the characters in the preset key can be analyzed only by accurately identifying each binary system, and the difficulty coefficient of key analysis is increased.

In either way, due to the nature of mechanical vibrations, a problem needs to be solved first: how to set the representation method of the number 0. In wireless signal transmission, coding is generally performed using manchester coding technology to realize identification of data such as consecutive 0 s or 1 s without a clock synchronization signal. However, in the process of transferring a key by vibration, if non-vibration is represented as 0, it is easy to confuse the time when no data is transmitted with the transmission time representing the digital 0, resulting in erroneous key identification. Therefore, a setting mechanism is required to effectively distinguish the time period of transmitting the digital 0 from the time period of no data transmission.

In the digital coding process of the vibration data, the invention adopts a +1 method to realize coding, and avoids the identification error easily caused by a digital 0. In the encoding process, 1 is used to represent 0, 2 represents 1, and so on 10 represents 9. The corresponding vibration data encoded under the two-bit system encoding scheme is composed of 2 and 1. According to the principle of the time length coding scheme described above, the number 0 is represented by a 1 millisecond vibration time after coding, and the number 1 is represented by a 2 millisecond vibration time after coding. For example, the modified binary-coded representation of the number 0 is 11 and the modified binary-coded representation of the number 1 is 21.

In the internet of things pairing method applied to the responder, after the key request sent by the pairing base station is verified, the preset key is converted into the vibration data, the vibration data is sent to the pairing base station for analysis, and the key is transmitted in a mechanical vibration mode through the vibration data, so that the risk that the key is easily attacked and interfered by types such as 'attack of a third party' and the like during wireless channel transmission is avoided.

Example four

The broadcast module 410 is specifically configured to: judging whether a responder which is in communication connection with a base station exists in the communication range of the base station; if yes, stopping broadcasting the key request; if not, the key request is broadcasted outwards at the first frequency periodically, and the key request comprises the identity information of the base station. The method maintains the base station to operate in a low energy consumption state without receiving and analyzing the key, and periodically broadcasts the key request to the outside at the first frequency, so that the vibration data can be fed back in time after the responder enters the communication range of the base station. The key request broadcast by the broadcast module 410 includes the base station identity information, which is intended to provide an identification mark for the responder, and avoid the energy waste and key leakage caused by the subsequent pairing process triggered by the responder after entering the communication area of the non-paired base station. The broadcasting module 410 broadcasts the key request only when it is determined that the transponder is not within the communication range, and if the key is within the communication range and the link is established, the base station stops broadcasting the key request, thereby reducing unnecessary energy consumption and realizing the function of energy protection.

And a key receiving module 420, configured to receive, at a second frequency, vibration data returned by the transponder based on the key request, where the second frequency is greater than the first frequency, and the vibration data is generated by the transponder after the identity information of the base station is verified.

The key receiving module 420 is specifically configured to: detecting whether vibration data reaching a preset threshold exists in the communication range in a low-frequency mode; if so, receiving the vibration data at a second frequency, converting the vibration data into vibration data by the responder according to a preset encoding algorithm and a preset key, and returning the vibration data in a mechanical vibration mode, otherwise, keeping a low-frequency mode to sense vibration. The key receiving module 420 collects the whole course high-frequency vibration data of the sensed vibration in the vibration time period to obtain vibration data, and monitors in a low-frequency mode when the vibration is not detected, and enters a high-frequency data sampling state after the vibration is detected to exist until the vibration stops detecting the vibration data and then returns to the low-frequency monitoring mode.

And a key analysis module 430, configured to analyze the vibration data to obtain a preset key.

In some embodiments, the key resolution module 430 includes:

the character analysis unit is used for analyzing a single character of the vibration data through a key character analysis algorithm and determining character information corresponding to the vibration data;

the time analysis unit is used for analyzing the time interval of the character string from the vibration data through a key character string starting time judgment algorithm;

and the key determining unit is used for determining a preset key corresponding to the vibration data according to the character information and the time interval.

The character analysis unit is used for ensuring the integrity and the accuracy of character string analysis, and the time analysis unit is used for avoiding the generation of key string codes and ensuring the validity of generated keys.
