Embodiment Construction

[0036] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0037] The present invention is aimed at the problem that mifare technology and the DES algorithm in the financial electronic wallet are used in the prior art. When the financial electronic wallet deposits, the data is transmitted in plain text, the security of data storage and transmission cannot be guaranteed, and the transaction process is too complicated. A new method of increasing and deducting the emission data of IC card is proposed.

[0038] The present invention proposes a new method for increasing sewage discharge data of an IC card. The software system for realizing the method is used to download to the user card as the only card of an enterprise, and can also be downloaded to the ESAM ( Embedded Secure Acce...

Abstract

The invention discloses a method for increasing and deducting the sewage discharge data of an IC card and an IC card, wherein the method for increasing the sewage discharge data of the IC card includes: receiving an instruction for increasing the sewage discharge amount issued by a recharging device, and the instruction for increasing the sewage discharge amount includes: first Random number: judging whether the first random number is random, if the first random number is random, the command to increase the amount of pollutant discharge is legal, and the recharge operation of the recharge device is accepted. The method for increasing and deducting the sewage data of the IC card and the IC card of the present invention introduce the concept of random numbers in the sewage discharge command, effectively preventing illegal users from intercepting the recharge data and performing multiple recharges; and introducing a special authentication code measure , the special authentication code is written into the security data area of ​​the chip, which prevents the generation of cloned chips; the introduction of the check code measures prevents the transmission error of the sewage data or the illegal attack during the transmission process, thus ensuring the pollution discharge Security and confidentiality of data during transmission.

Description

technical field [0001] The invention relates to the technical field of data transmission and safety in the communication field, in particular to a method for increasing and deducting sewage discharge data of an IC card and an IC card. Background technique [0002] The pollutant discharge permit system is aimed at improving environmental quality, based on the total amount of pollutant discharge control, and stipulates the types and data of pollutants discharged by pollutant discharge units. It is an administrative management system with legal implications. , The means of quantitative management of the main pollutant discharge of key pollutant discharge units. In the past, in the process of pollution source remediation, only the emission concentration was controlled, and the pollution problem could not be solved as a whole. Only by controlling the total amount of emission from key pollution sources and issuing pollutant discharge permits can the environmental quality of the en...
