The invention discloses a gas meter reading system based on a national cryptographic algorithm and a gas data transmission method thereof. The system comprises an information acquisition device, a central information processor, a national cryptographic algorithm module, a receiving terminal and the like. The method comprises the steps that fuel gas data is collected; meter reading data is generated; the national cryptographic algorithm module encrypts the meter reading data to generate a first ciphertext, encrypts a first abstract of the first ciphertext to generate a first abstract ciphertext, and then sends the first ciphertext and the first abstract ciphertext to the receiving terminal; and the receiving terminal decrypts the first abstract ciphertext to obtain a first abstract, recalculates the abstract of the first ciphertext to obtain a second abstract, and decrypts the first ciphertext to obtain meter reading data after the second abstract is successfully matched with the firstabstract. Through a dual encryption mode of encrypting and transmitting the meter reading data and encrypting and transmitting the first abstract of the first ciphertext, the meter reading data can beobtained only after dual encryption verification succeeds, so that the data transmission security is greatly improved, and stealing is prevented.
Description
technical field [0001] The invention relates to the technical field of gas data processing, in particular to a gas meter reading system based on a national secret algorithm and a gas data transmission method thereof. Background technique [0002] The gas distributed by the gas supply industry mainly includes coal gas, liquefied petroleum gas and natural gas. my country's gas supply has increased significantly since the 1990s. Among them, after a substantial increase in the supply of artificial gas in 1990, it was in a relatively slow growth stage due to its shortcomings such as high pollution and strong toxicity; the supply of liquefied petroleum gas remained stable due to the impact of rising oil prices; The calorific value of natural gas is 30%-50% cheaper than gasoline and diesel, which is obviously economical. At the same time, the country pays more and more attention to environmental protection, and the market demand for clean energy continues to grow. Consumption has...
