Based on the hardware structure, the embodiment of the communication method of the Internet of things is provided.
The invention provides an internet of things communication method, which is mainly applied to a first terminal, wherein in an embodiment of the internet of things communication method, the first terminal is in signal connection with a preset first management unit, and referring to fig. 2, the internet of things communication method comprises the following steps:
step S10, the first terminal acquires a first execution instruction, and acquires a first receiving address of the second terminal from the first execution instruction;
step S20, the first terminal performs public key encryption processing on the first execution instruction to generate a first encryption instruction;
step S30, the first terminal obtains a first delivery address and carries out digital signature processing on the first encryption instruction, the first delivery address and the first receiving address to generate a first signature mail;
step S40, the first terminal sends the first signature e-mail to the first management unit, so that the first management unit forwards the first signature e-mail to a second management unit in signal connection with the second terminal according to the first recipient address.
In the invention, the first terminal is an Internet of things device (such as a mobile phone, an intelligent household device and the like), and is in signal connection with other Internet of things devices through the Internet of things to realize data communication. The Internet of things equipment receives the e-mails sent by other Internet of things management units in real time, executes related operations, and sends one e-mail to the other side according to the needs after the operations are completed. The communication between the devices of the internet of things and human beings all conform to standard mail protocols including SMTP, IMAP and the like, and SSL transmission encryption protocol is adopted to ensure the communication safety.
The invention adopts a decentralized network structure to process the communication between the devices of the Internet of things, and adopts decentralized networking technology, which is similar to an electronic mail system, and adopts a related protocol-S/MIME to process the data of the Internet of things. Each internet of things management unit is a mail server, and each managed internet of things device is an email account on the mail server, that is to say: identifying each internet of things device with an e-mail box; the management units of the internet of things adopt an SMTP protocol for communication and data exchange, so that each piece of internet of things equipment can safely communicate with any piece of internet of things equipment like an electronic mailbox of each person, and can be interconnected and intercommunicated with an electronic mail system of a human, and communication among the pieces of internet of things equipment and communication between the pieces of internet of things equipment and the human are realized.
The specific contents are as follows:
step S10, the first terminal acquires a first execution instruction, and acquires a first receiving address of the second terminal from the first execution instruction;
in this embodiment, each piece of internet-of-things equipment is set as a mail server, instruction information is sent in a mail form, the equipment receives the instruction information in the mail, and then corresponding instruction operation is executed.
The first execution instruction is preset by a person, or is generated intelligently by the device (for example, the device wakes up another device regularly). The first terminal acquires a first execution instruction and acquires a device mailbox address for receiving the first execution instruction from the first execution instruction. For example, the operations to be performed by the first execution instruction are: the control device information is a and the device numbered a performs the music play operation. Then, the first execution instruction includes the number of the device to execute the instruction, and also includes device information a, where the device information a includes a mailbox address, and the mailbox address is the first recipient address. At this time, the device is the second terminal.
Step S20, the first terminal performs public key encryption processing on the first execution instruction to generate a first encryption instruction;
in order to avoid the damage and the theft of the external malicious program data, the embodiment encrypts the first execution instruction. The encryption process adopts a public key and private key encryption algorithm, and the public key is a public encryption key which is disclosed to each management unit and each equipment end of the Internet of things. The first terminal can directly obtain the public key, and the first execution instruction in the plaintext form is encrypted into the ciphertext form through the public key, so that the first encryption instruction is generated. The encryption process can serve as a data leakage prevention.
Step S30, the first terminal obtains a first delivery address and carries out digital signature processing on the first encryption instruction, the first delivery address and the first receiving address to generate a first signature mail;
and sending the first execution instruction in an email form, wherein the first execution instruction needs to be provided with a first sending address, a first receiving address and a first execution instruction. In this embodiment, each internet of things device binds to the email account corresponding to the identifier, so that the first terminal also includes the corresponding first delivery address to obtain the email address. The first terminal carries out digital signature on the first encryption instruction, the first sending address and the first receiving address so as to obtain a first signature mail. The digital signature processing can play a role in preventing data fraud, and prevents the second terminal from receiving harassing mails and fraudulent mails. The first signature mail is a mail containing a first execution instruction, the plaintext instruction content is encrypted by using a public key, and the instruction mail is signed by using a certificate of the first signature mail, so that the mail cannot be tampered and the integrity of the mail can be guaranteed. The first execution instruction is packaged through the mail, so that the first execution instruction can be protected by a mail protocol in the mail, and data leakage is avoided.
Further, the step S30 includes:
a first terminal acquires a first time stamp and first warp-weft information from a preset legal verification source;
each Internet of things device is provided with a trusted computing chip and a digital certificate representing the identity of the device, the digital certificate is bound with an e-mail address of the device, mini encrypted e-mail client software or a chip is arranged in the Internet of things device and used for receiving encrypted mails from an Internet of things management unit and sending digital signatures and encrypted mails, an S/MIME protocol is adopted, the digital signatures in the mails are used for proving the identity of other communication devices, and the encrypted mails ensure that exchanged information can be decrypted, read and executed only by a receiving device. All communications will be time stamped with location information as needed to effectively document the time of message delivery and the location information delivered.
Specifically, time is identified by timestamp data, and location position information is identified by longitude and latitude information. In order to avoid data fraud, the embodiment adopts a preset legal verification source to obtain the first timestamp and the first longitude and latitude information of the first terminal, wherein the legal verification source is an information verification source which is authenticated by the first terminal and the second terminal together in the invention, and digital visa proofreading service is provided for the first terminal and the second terminal. The first terminal may acquire the first timestamp and the first warp information from a legally verified source before sending the mail.
And b, the first terminal carries out digital signature processing on the first encryption instruction, the first delivery address and the first receiving address according to a first timestamp and first warp information to generate a first signature mail.
And according to the first timestamp and the first longitude and latitude, the first terminal carries out digital signature processing on the first encryption instruction, the first sending address information and the first receiving address information to generate a first signature mail. The first signature mail processed by digital signature is the legal authentication mail of the invention, and any terminal can analyze and execute corresponding instruction operation only by receiving the first signature mail processed by digital signature.
The following is an example of the embodiment, the first terminal acquires the first timestamp 20190501 and 183058 from the legal verification source, acquires the first longitude information as north latitudes 39 ' 26 ' to 41 ' 03 ', and acquires the east longitudes 115 ' 25 ' to 117 ' 30. Then the first terminal carries out digital signature processing according to the first timestamp and the first warp information, so as to mark a digital signature for the first delivery address, the first receiving address and the first encryption instruction, so that the first delivery address, the first receiving address and the first encryption instruction have distinguishable attributes, and the first signature mail is generated by encapsulation.
By using the timestamp and the longitude and latitude information to carry out digital visa, the method and the system can improve the resolution efficiency of the mail information, prevent the internal data security of the Internet of things equipment from being damaged by cheating mails, and greatly improve the communication security between the Internet of things equipment.
Step S40, the first terminal sends the first signature e-mail to the first management unit, so that the first management unit forwards the first signature e-mail to a second management unit in signal connection with the second terminal according to the first recipient address.
After the first signature mail is acquired, the first terminal uploads the first signature mail to the first management unit, and then the first management unit forwards the first signature mail, so that the first signature mail acquired from the first terminal is forwarded to the second management unit associated with the first recipient address, and then the second management unit issues the first signature mail to the second terminal corresponding to the first recipient address. It can be understood that the first receiving address is a basis for the first management unit and the second management unit to forward and issue the first signed e-mail, and the encryption and digital signature process ensures the safety of the e-mail in the forwarding process.
Referring to fig. 3, each internet of things device corresponds to one management unit. One management unit may serve multiple devices. Can communicate with two devices belonging to a management unit; two devices belonging to different management units can also communicate normally.
The first terminal of the device belongs to the first management unit, and the second terminal of the device belongs to the second management unit. The first terminal sends the encrypted and signed mail to the first management unit, the first management unit forwards the mail to the second management unit, and the second terminal acquires the instruction mail sent by the first terminal from the second management unit and executes the instruction mail.
After receiving the instruction mail sent by the first terminal, the second terminal sends a response mail to the second management unit, the second management unit forwards the response mail to the first management unit, and the first terminal acquires the response mail from the first management unit to complete the communication process.
Further, the first terminal and the second terminal may be under the same management unit, and referring to fig. 4, the first terminal and the second terminal are under the first management unit, then the second management unit in the present invention is the first management unit at this time, the first terminal sends the mail with the encrypted signature to the first management unit, and since the first recipient address is the device under the management unit, the second terminal may directly obtain the instruction mail sent by the first terminal from the first management unit and execute the instruction mail. Similarly, after the response email of the second terminal is sent to the first management unit, the first terminal can obtain the response email from the first management unit.
In the invention, a first terminal acquires a first execution instruction and acquires a first receiving address of a second terminal from the first execution instruction; the first terminal carries out public key encryption processing on the first execution instruction to generate a first encryption instruction; a first terminal acquires a first sending address and carries out digital signature processing on the first encryption instruction, the first sending address and the first receiving address to generate a first signature mail; and the first terminal sends the first signature mail to the first management unit so that the first management unit forwards the first signature mail to a second management unit in signal connection with the second terminal according to the first recipient address. The invention adopts a decentralized structure, simplifies the system structure, does not communicate in a command transmission mode, but transmits the command through the mail encryption signature, avoids external malicious attack, and ensures the data purity of the internal equipment of the Internet of things, thereby improving the resistance to external data invasion, data fraud and data leakage, further improving the communication safety among the equipment of the Internet of things, and improving the safety level of the communication of the Internet of things.
Further, based on the first embodiment, a second embodiment of the method is proposed, in which,
the step that the first terminal sends the first signature mail to the first management unit so that the first management unit forwards the first signature mail to a second management unit in signal connection with the second terminal according to the first recipient address further comprises the following steps:
step S50, if the first terminal does not acquire the first response mail fed back by the second terminal based on the first signature mail within the preset time, the first terminal re-performs digital signature processing on the first encryption instruction, the first delivery address and the first receiving address to generate a second signature mail;
after sending out the first signature mail, the second terminal executes relevant operation according to the first signature mail. However, in real life, there may be a situation that the management unit is down or the first terminal is not connected, which may cause a situation that the second terminal does not receive the mail because the first management unit or the second management unit cannot forward the first signed mail due to a fault after the first signed mail is sent to the first management unit. Therefore, the second terminal feeds back the response mail to the first terminal after performing the relevant operation, and if the response mail is not received, it is proved that the second terminal may not receive the first signature mail. In this embodiment, after the first signature email is sent out, a preset time is used as a buffer period, and the response email fed back by the second terminal is not obtained within the preset time, so that the first terminal resends the email to ensure that the second terminal device can execute relevant operations in time. However, since the transmitted mail needs to be repackaged, the digital signature process needs to be performed again, and the second signed mail is generated by digitally signing the mail with information such as a time stamp and latitude and longitude.
Step S60, the first terminal sends the second signed e-mail to the first management unit, so that the first management unit forwards the second signed e-mail to a second management unit in signal connection with the second terminal according to the first recipient address.
The first terminal resends the second signature mail to the first management unit for the first management unit to forward according to the first receiving address. It can be understood that if the first terminal still does not obtain the response mail based on the second signature mail within the preset time after the second signature mail is sent, the first terminal continues to generate a new signature mail and sends the new signature mail to the first management unit for forwarding until the packaged mail of the instruction to be executed is sent to the second terminal.
Through the embodiment, the phenomenon that the second terminal does not execute corresponding functional operation due to the fact that things or faults of the intermediate forwarding link occur can be avoided, and the completeness of mail communication is improved.
Further, based on the first embodiment, a second embodiment of the method is provided, in which the method for communicating the internet of things further includes:
step A, a first terminal acquires a third signature mail forwarded by a first management unit;
step B, the first terminal conducts signature verification processing on the third signature mail to determine whether the third signature mail passes signature verification;
each management unit of the internet of things has an access control rule, and the second terminal in the implementation can be set to receive only mails with digital signatures and encrypted mails and can be set to receive only encrypted mails sent by mailboxes with domain names, so that the problem of spam on the internet is prevented from happening on the internet of things.
In this embodiment, any one of the internet of things devices can send and receive mail information. And if the first management unit acquires the third signature mail forwarded by the first management unit, performing signature verification processing on the mail. The signature verification processing is signature verification processing, and the processing step verifies whether the third signature mail is a legal mail or not so as to avoid malicious operations such as data intrusion, data stealing and the like of malicious mails such as cheat mails, phishing mails or attack mails and the like.
Step C, if the first terminal detects that the third signature mail passes signature verification, a second encryption instruction, a second sending address and a second receiving address are obtained from the third signature mail;
specifically, the step C includes:
step C1, the first terminal acquires a second timestamp and second longitude and latitude information in the third signature mail;
step C2, the first terminal acquires a third timestamp and third longitude and latitude information matched with the third signature mail from a preset legal verification source;
the second timestamp and the second longitude and latitude information are verification data samples for the first terminal to confirm that the third signature mail is legal, and after the second timestamp and the second longitude and latitude information are obtained, the first terminal needs to obtain the third timestamp and the third longitude and latitude information which are matched with the third signature mail from a legal verification source. Since whether the third signed e-mail received by the first terminal is legal or not is unknown, the third timestamp and the third longitude and latitude information of the third signed e-mail stored on the legal verification source need to be judged.
Step C3, if the first terminal detects that the second timestamp is matched with the third timestamp and the second longitude and latitude information is matched with the third longitude and latitude information, the first terminal confirms that the third signed e-mail passes signature verification;
if the second timestamp is matched with the third timestamp (for example, the timestamps are uniform), and the second longitude and latitude information is matched with the third longitude and latitude information (for example, the longitude and latitude are uniform), the third signed mail can be confirmed to pass the signature verification. On the contrary, if any data of the timestamp or the longitude and latitude information does not match, the signature verification is not passed.
And step C4, the first terminal acquires the second encryption instruction, the second sending address and the second receiving address from the third signed mail passing the signature verification.
And the third signed e-mail passing the signature verification is a legal e-mail, and at the moment, the first terminal executes the operation of obtaining the second encryption instruction, the second sending address and the second receiving address for subsequent use.
Through the verification of the timestamp and the longitude and latitude information, most of malicious mail information such as fraudulent mails, phishing mails and attack mails can be filtered out, and the data safety and the communication safety in the Internet of things equipment are guaranteed.
D, the first terminal performs private key decryption processing on the second encryption instruction to obtain a second execution instruction;
the second encryption instruction is formed by encrypting through a public key and private key encryption algorithm, and decryption can be performed through private key decryption processing after the second encryption instruction is obtained. Each terminal has respective private key data, and only the device can decrypt and obtain correct decrypted data. By decrypting the second encryption instruction, the first terminal can convert ciphertext data in the second encryption instruction into plaintext data, so as to obtain a second execution instruction in a plaintext form.
Step E, the first terminal executes the instruction operation corresponding to the second execution instruction;
step F, if the first terminal finishes the instruction operation, generating a second response mail based on the second sending address, the second receiving address and a third signature mail;
and the first terminal executes corresponding instruction operation according to the second execution instruction. In order to complete the mail communication, after the instruction operation is completed, a first response mail is generated based on the second sending address, the second receiving address and the second signature mailbox address, and the response mail is mainly sent to a receiving terminal corresponding to the second receiving address to inform the receiving terminal that the communication is completed, so that the effect of finishing the communication is achieved.
And G, the first terminal sends the second response mail to the first management unit so that the first management unit can forward the second response mail according to the second receiving address.
And the first terminal sends the second response mail to the first management unit, and the first management unit sends the second response mail to the corresponding management unit for forwarding so as to finally reach the receiving terminal corresponding to the second receiving address.
It can be understood that any internet of things device in the invention can be a first terminal and a second terminal, the first terminal can decrypt the private key after verifying the signature of the third signature email, and if the signature verification fails or the email ciphertext is decrypted fails, the email is discarded without performing any operation.
Further, based on the second embodiment, a third embodiment of the method is provided, in which step G further includes:
and step H, the first terminal acquires the finished mail serial number of the second response mail and stores the finished mail serial number to a finished instruction list.
In this embodiment, the first terminal acquires the completed email serial number of the second response email, where the serial number provides identification information of the third signature email, and the first terminal may store the execution record of the device communication and store the execution record in the completed instruction list when acquiring the serial number. And storing the corresponding completed mail serial number into a completed instruction list every time the execution operation is completed.
Further, after H, if step B is executed, step B includes:
step B1, the first terminal obtains the serial number of the mail to be verified of the third signature mail;
step B2, if the first terminal detects that the completed email serial number matched with the email serial number to be verified does not exist in the completed instruction list, the first terminal performs signature verification processing on the third signed email to determine whether the third signed email passes signature verification.
In the process of sending and acquiring the mails, the first terminal cannot send out the response mails in time due to the fault or delay of the information transmission or management unit, so that the communication is not finished; if terminal A retransmits the mail, terminal B needs to confirm whether the execution procedure of the re-mail is completed, if so, the mail can be ignored, if not, the relevant operation needs to be executed.
In this embodiment, if the first terminal detects the third signed e-mail, the first terminal may obtain the serial number of the e-mail to be verified in the e-mail, and retrieve the serial number. And if the completed mail serial number corresponding to the mail serial number to be verified exists in the completed instruction list, the fact that the execution function operation referred by the current third signature mail is executed by the first terminal is proved to be completed without executing again. Otherwise, it is proved that the first terminal has not executed the function operation corresponding to the third signed e-mail, and the first terminal needs to check the third signed e-mail to determine whether the e-mail is a legal e-mail.
By processing the second signature mail, the phenomenon that the management unit, the first terminal or the second terminal misses the execution operation due to downtime or faults is avoided.
