The invention relates to an intelligent IC card metering device with a hardware encryption function. The device comprises a data metering unit, a controller and an IC card reading-writing unit, wherein an output end of the data metering unit is connected to a data input end of the controller and used to send metering data for the controller. The device is characterized by comprising an encryption-decryption module, wherein the encryption-decryption module comprises a processor and a storage unit; a double-way connection is formed between the processor and the controller, so that data communications between the processor and the controller can be completed; a double-way connection is formed between the processor and the IC card reading-writing unit, so that data communications between the encryption-decryption module and the IC card reading-writing unit can be completed; and a double-way connection is formed between the storage unit and the processor, so that the storage unit can store encryption-decryption program information and data information of the encryption-decryption module. The intelligent IC card metering device has the advantages that the structure is simple; confidentiality is high; identity authentication can be conducted accurately; data safety of the intelligent IC card metering device is enhanced; and economic properties of a user are also guaranteed.
Description
technical field [0001] The invention relates to the field of measuring instruments, in particular to an intelligent IC card measuring instrument with hard encryption function. Background technique [0002] With the continuous advancement of science, smart metering instruments are more and more widely used in production and life. Meters can be divided into two types in terms of payment methods: one is to pay first and then use it, which is called prepayment, such as IC card meter, and the other is to use it first and pay later, which is called postpayment, such as ordinary meter. Among them, the IC card meter needs to be paid first, and then used, which involves the security of the IC card recharge. At present, the smart IC card metering instruments that appear on the market have hidden dangers in security issues when users pay for recharging. Even if there is an IC card measuring instrument with higher safety performance, its production cost is also higher, which is not co...
