Smart card containing Mifare functional module and data updating method thereof

Abstract

The invention discloses a smart card with a Mifare functional module and a data updating method, including: the Mifare functional module, updating the data stored in the Mifare functional module according to the received charging or consuming command information; a control module controlling the Mifare functional module and updating the data according to the charging command information when receiving the charging command information. The invention represents the convenience of Mifare function also can exert the high safety of the CPU smart card in the CPU card or KEY and the like including the Mifare function, which finally advances the whole safety of the application system.

Description

technical field [0001] The invention relates to data security, in particular to a smart card containing a Mifare function module and a data updating method thereof. Background technique [0002] At present, the products of the Mifare family have been widely used in non-contact applications around the world. They mainly contain non-contact logical encryption cards (Mifare Standard) with certain security, and are mainly used in urban pass cards that require certain security or convenience. , public utility cards (including water, coal, electricity, gas meter cards, etc.), parking charge debit cards, various VIP cards and other application fields, when it is necessary to recharge or consume, the Mifare function module only needs to The recharge or consumption command message updates the data stored in the Mifare function module, so that the amount mapped to the data in the card can be recharged or consumed. With the maturity of micropayment applications, more and more differen...

AI Technical Summary

Problems solved by technology

For the wallet, there are recharge and consumption functions. For the system attacker, if the consumption function is cracked, the amount of the attacker / user's wallet will be reduced, and the attacker will not have more benefits, nor will it make much sense; therefore, If the recharge function is cracked, the amount of the attacker / user wallet will increase, and the attacker will get a lot of benefits, which will drive the attacker to more attacks

[0006] However, the deficiency of the existing technology is that there is no solution for the decline of the security of the entire application system due to the low security of the Mifare part
