Description

Technical Field

[0001] The present invention belongs to the technical field of electronic digital data processing, and in particular relates to a method and system for secure encryption transmission of Internet of Things data. Background Art

[0002] IoT data security encryption refers to the use of encryption technology to protect data during transmission in the IoT environment, ensuring the confidentiality, integrity and availability of data during transmission, and preventing the transmitted data from being tampered with or leaked. IoT devices usually collect and transmit a large amount of information, such as technical solution data and commercial confidential data. Encryption technology is a key means to ensure the security of this information, which can prevent data from being stolen or maliciously used, maintain the stable operation of the IoT system, and protect the interests of users.

[0003] IoT data needs to be shared and interacted between different platforms, but the encryption standards and encryption technologies of different platforms may be different, which makes it difficult to achieve secure data sharing during the transmission process between the two platforms. That is, one platform cannot receive the transmission data of another platform or the other platform cannot receive the transmission data of one platform, and the transmission data will be leaked, increasing the risk of transmission data leakage. Summary of the invention

[0004] The present invention provides a method and system for secure encryption transmission of Internet of Things data, which are used to solve the technical problems of secure transmission and sharing of Internet of Things data. By judging whether the passwords added to two mutually transmitted data generated in the same time period or in a certain time period are the same, it is determined whether the two mutually transmitted data can be transmitted to each other. Under the condition that the passwords added to the two mutually transmitted data are the same, after data interaction for one transmission data, one transmission data is sent out and received, and after data interaction for the other transmission data, the other transmission data is sent out and received. In this way, the two mutually transmitted data can be transmitted and received to each other.

[0005] In order to achieve the above object, the present invention is implemented by the following technical solutions:

[0019] Optionally, in step S2, a function separation method is used to determine whether the passwords added to two mutually transmitted data generated in the same time period are the same. The function separation method is the following formula (2):

[0020] (2);

[0021] in, A password added to the transmitted data. To detect a password added to a transmission, A password added to another transmission data. To detect a password added to another transmission;

[0022] Password separator, a password added to the transmission data Password added to another transmission data to separate;

[0024] For time detection operation, detect a password added to the transmitted data Password added to another transmission data Whether it is within the same time period;

[0025] To determine the password added to a transmission data within the same time period Password added to another transmission data Are they the same? To judge the result.

[0026] Furthermore, to determine whether the passwords added to two mutually transmitted data generated in the same time period are the same, the following steps are adopted:

[0027] Step a: within a certain time period, detecting the number of passwords, password characters and the order of password characters of a password added to a transmission data;

[0030] Among them, in step c, whether the passwords added to the two mutually transmitted data are the same determines whether the two mutually transmitted data can be transmitted.

[0031] Optionally, in step S3, the password added to the transmission data output after the transmission data is interacted with other data remains unchanged.

[0032] Optionally, in step S4, after another transmission data is interacted with through other data, the password added to the other transmission data outputted remains unchanged.

[0033] Optionally, in step S5, a password is regenerated after a certain period of time, and a password is added to each of the two mutually transmitted data, and the passwords added to the two mutually transmitted data are the same.

[0063] Step S2: Determine whether the passwords added to the two mutually transmitted data generated in the same time period are the same. If the passwords added to the two mutually transmitted data are the same, the two mutually transmitted data can be transmitted to each other. If the passwords added to the two mutually transmitted data are different, the two mutually transmitted data cannot be transmitted to each other.

[0073] Set a time period. The length of the time period is determined according to the setting. The time period can be 1 hour or 2 hours. The passwords added to the two mutually transmitted data are added at the same time (that is, the passwords added to the two mutually transmitted data are added within 1 hour or 2 hours). The passwords added to the two mutually transmitted data do not change within a time period, because the passwords added to the two mutually transmitted data have been automatically set within a time period (that is, within 1 hour or 2 hours). The passwords within a time period do not change.

[0074] The passwords added to the two mutually transmitted data are automatically generated within the same time period (ie, within 1 hour or 2 hours), and the passwords added to the two mutually transmitted data are randomly generated within the same time period.

[0086] Step b: within a certain time period, detecting the number of passwords, password character content and password character arrangement order of the password added to another transmission data;

[0087] Step c: If within a certain time period, the number of passwords, the content of password characters and the arrangement order of password characters of the password added to one transmission data are the same as the number of passwords, the content of password characters and the arrangement order of password characters of the password added to another transmission data, then the passwords added to the two mutually transmitted data are the same; otherwise, the passwords added to the two mutually transmitted data are different;

[0088] Among them, in step c, whether the passwords added to the two mutually transmitted data are the same determines whether the two mutually transmitted data can be transmitted.

[0089] In addition, in step S3, the password added to the transmission data output after the transmission data is interacted with other data remains unchanged.

[0090] In step S4, after another transmission data is exchanged through other data, the password added to the other transmission data outputted remains unchanged.

[0091] In step S5, a password is regenerated after a certain period of time, and a password is added to each of the two mutually transmitted data, and the passwords added to the two mutually transmitted data are the same.

[0092] Embodiment 5;

[0093] Based on all the above embodiments, Figure 1-Figure 3 As shown, the time is calculated by the time counting unit, and the password setting module uses the time counting unit to calculate the time so as to generate a password within a certain time period.

[0094] like Figure 2 As shown, within a certain period of time and Under the same conditions, with the added password The data in the first data platform is transmitted to the data interaction platform, and the user accesses the data with the added password through the data interaction platform. Data in the first data platform (because the user knows the password ), the data interaction platform has a password added The data in the first data platform is then transmitted to the second data platform through the data interaction platform, and the second data platform can receive the data with the password added. The data in the first data platform is encrypted because the password added to the data in the first data platform The password added to the data in the second data platform Same, as long as and Similarly, the second data platform allows access to the first data platform.

[0095] Similarly, if Figure 3As shown, within a certain period of time and Under the same conditions, with the added password The data in the second data platform is transmitted to the data interaction platform, and the user accesses the data with the added password through the data interaction platform. The data in the second data platform (because the user knows the password ), the data interaction platform has a password added The data in the second data platform is then transmitted to the first data platform through the data interaction platform, and the first data platform can receive the data with the password added. The data in the second data platform is encrypted because the password added to the data in the second data platform The password added to the data in the first data platform Same, as long as and Similarly, the first data platform allows access to the second data platform.

[0096] After a certain period of time, the password setting module regenerates a password, which is the password added by the data in the first data platform and the data in the second data platform, and the passwords added by the two mutually transmitted data are still the same, ensuring that the data in the first data platform and the data in the second data platform are the same after a certain period of time.
