Embodiment 1

[0074] Embodiments of the present invention provide a communication method for an IoT meter, such as figure 1 As shown, the method includes the following steps:

[0075] In step S101, a communication key is obtained, wherein the communication key is a communication password determined after key negotiation between the IoT meter and the service management organization.

[0076] Specifically, in the prior art, when IoT meters communicate with business management organizations, all meters use the same key for data encryption. This communication method has great potential security risks. Once the key is leaked, others will All communication data can be decrypted by using this key, and the data security of the IoT meter cannot be guaranteed. Therefore, in the present invention, before the IoT meter communicates with the business management agency, it is necessary to negotiate and confirm a communication after two-way identity authentication. password, and use this communication pa...

Embodiment 2

[0089] figure 2 is a flow chart of an optional communication method for an IoT meter according to an embodiment of the present invention, such as figure 2 As shown, the method includes the following steps:

[0090] In step S11, a communication key is obtained, wherein the communication key is a communication password determined after key negotiation between the IoT meter and the service management organization.

[0091] The acquisition of the communication key has been described in detail in the above-mentioned Embodiment 1, which is not repeated here, and the process of acquiring the communication key will be described in detail below.

[0092] Step S12, using the communication key to encrypt the first uplink data of the IoT meter to obtain the first uplink ciphertext, and sending the first uplink ciphertext to the service management organization, wherein the first uplink data includes: uplink service The sending time of data and uplink service data.

[0093] The sending...

Embodiment 3

[0131] Embodiments of the present invention provide a communication method for an IoT meter, such as image 3 As shown, the method includes the following steps:

[0132] Step S201, receiving the first uplink ciphertext sent by the IoT meter.

[0133] Step S202: Decrypt the first uplink ciphertext by using a communication key, where the communication key is a communication password determined after key negotiation between the IoT meter and the service management organization.

[0134] Specifically, when the business management agency conducts business communication with the IoT meter, it will first receive the first uplink ciphertext sent by the IoT meter, and then use the IoT meter to negotiate a key with the business management agency to determine the value. The communication password (communication key) decrypts the first uplink ciphertext to obtain service data carried by the first uplink ciphertext.

[0135] Step S203: Encrypt the first downlink data by using the communi...

Abstract

The invention provides a communication method, device and system for an Internet of Things meter, relating to the technical field of meter data communication, including obtaining a communication key determined after key negotiation between the Internet of Things meter and a business management organization; using the communication key The key encrypts the first uplink data of the Internet of Things meter and sends it to the business management agency; receives the downlink business data returned by the business management agency; executes the business operation instructions carried by the downlink business data, obtains the execution result and sends it encrypted to the business management agency governing body. In the method of the present invention, when the meter of the Internet of Things and the business management organization are in business communication, the communication key is obtained after the key negotiation between the two parties, which realizes one table and one secret, ensures the confidentiality of communication data, and alleviates the current situation. There is a technical problem that the communication method of the Internet of Things meter has low security.

Description

technical field [0001] The invention relates to the technical field of meter data communication, in particular to a communication method, device and system for an Internet of Things meter. Background technique [0002] In recent years, the Internet of Things, as a new generation of information technology, has been widely used in various technical fields. For example, the Internet of Things technology can be applied to various meters such as gas dials, water dials, and electric dials. The meter realizes the collection and transmission of data in a remote way, which changes the traditional meter reading method, thereby simplifying the workload and improving the efficiency, and has become the best choice for a new generation of meter terminals. [0003] In the prior art, when IoT meters communicate with a business management organization, all meters use the same key for data encryption. If the key is leaked, it means that the communication data of all meters can be decrypted. ...
