In privately owned memory space E2.
Further, in step (3-4), enciphering/deciphering program reads the key deposited in inside reader, stores it in
Privately owned memory space E1；In step (3-7), data S1 and key E2 is subjected to computing by certain algorithm, after forming decryption
Data, are stored in privately owned memory space R1；In step (3-8), the data in R1 are for users to use.
A kind of control module based on RFID card, further, its built-in above-mentioned decryption program, and/or enciphering/deciphering are calculated
Method.
Compared with currently available technology, data ciphering method of the invention is global unique UID using every card itself
Code, by changing computing, is encrypted the data field of card by a reversible Encryption Algorithm.Data safety is reliable, and prevents
Only data duplication.Synthesis encryption/decryption algorithm based on RFID card is the unique UID codes in the whole world using every card itself, by becoming
Change computing, the data field of card is encrypted by a reversible Encryption Algorithm.Data safety is reliable, and prevents data from answering
System.The very high hardware resource that is implemented without configuring of the algorithm supports, but can provide higher security.
Applied to consumption system of the large enterprise based on RFID card, which is stored in RFID using dinner cost is monthly provided
In card, worker can at any time, in the dining room of any networking, hold and self-recharging carried out in the top-up machines kept at nobody；As long as
Information is effective in card, can really realize all-purpose card in any Eatery Consumption, gives worker's great convenience.At the same time
The cost of a large amount of meal coupons of printing has been saved, has avoided and collects the loss that false tickets are brought.
The algorithm arithmetic speed is fast, securely and reliably, has extensive adaptability.
Brief description of the drawings
Fig. 1 is enciphering/deciphering protocol procedures figure of the present invention
Embodiment
Below according to attached drawing, the present invention will be described in detail, it is a kind of preferred real in numerous embodiments of the present invention
Apply example.
A kind of synthesis encryption/decryption algorithm based on RFID card, is mainly used for such as amount of money data to being stored on card
Enciphering/deciphering, include the following steps：Reader does not stop externally to send read-write requests order, after reader detects card, according to
The instruction received, if desired for specific data is read, then calls decryption program, S1:Data to be treated are read, are stored
