Abstract

The invention discloses a pollution discharge data secure transmission method and terminal and a system. The method comprises the steps that a random number is obtained from a user card, and an encryption result K1 is obtained after the random number is encrypted based on a built-in secret key of the user card; an encryption result K2 is obtained after the random number is encrypted based on a built-in secret key of the secure transmission terminal; the encryption result K1 and the encryption result K2 are compared, and if K1 is equal to K2, the user card passes authentication. The system comprises a pollution discharge system and a total quantity control system. The pollution discharge system comprises an environment-friendly background system and the total quantity control system, and the total quantity control system comprises the pollution discharge data secure transmission terminal. According to the pollution discharge data secure transmission method and terminal and the system, pollution discharge data are encrypted and decrypted based on a pre-appointed built-in secret key through an SM1 algorithm in the transmission process, and security and confidentiality of the pollution discharge data in the storage and transmission process are guaranteed.

Description

technical field [0001] The invention relates to the technical field of transmission and data services in the communication field, and in particular to a method, terminal and system for secure transmission of sewage data in a card swiping sewage system. Background technique [0002] In my country's existing card-swiping sewage system, sewage enterprises purchase pollutant discharge data through the Environmental Protection Tong IC card at the Environmental Protection Center, and use the Environmental Protection Tong IC card as the medium to transmit the sewage discharge data to the total pollutant discharge control system (hereinafter referred to as the total amount control system); The total amount control system uses disks or general-purpose memory chips to store blowdown data. The sewage equipment collector regularly transmits the sewage data to the total volume control system for calculation and deducts the disk data. When the collection equipment communicates with the to...
