Abstract

The invention provides a secure communication method and a system based on an identification algorithm, wherein the method comprises the following steps of: combining a security chip with an NB-IoT communication module is encapsulated into a security module and arranged in the terminal; when the terminal access the network for the first time, the terminal sends the request activation message to the background, the background receives the request activation message, verifies the authenticity of the identification signature data, if the verification is passed, the terminal generates the updateddistribution information according to the gas label, and sends the APDU instruction package to the terminal; the terminal verifies the authenticity of the update signature data, and if the verification is passed, the secondary distribution message cipher is decrypted to obtain the renewal distribution information, and the initial distribution information is replaced with the renewal distribution information to store the renewal distribution information; according to the grade of the reported data, the terminal sends the plaintext of the common data and the MAC value obtained by calculating thecommon data to the background, or sends the key data ciphertext obtained by encrypting the plaintext of the key data and the key data signature obtained by signing the key data ciphertext to the background.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and system for safe communication based on an identification algorithm. Background technique [0002] Narrow Band Internet of Things (NB-IoT) is built on a cellular network and only consumes about 180KHz of bandwidth. It can be directly deployed on a GSM network, UMTS network or LTE network, and has become an important branch of the Internet of Things. The NB-IoT network has the characteristics of large connection, low power consumption, low cost, and wide coverage, which meets the needs of smart gas terminals. The application of NB-IoT Internet of Things technology will promote the "Internet +" information construction of new gas management, promote the technical standardization and industrial scale of the gas industry, and jointly create an industry benchmark for smart gas. [0003] The NB-IoT module is a packaged communication module based on the NB-IoT baseband chip, which...
