Abstract
The invention relates to an access method of mass data in an RFID (Radio Frequency Identification Device) electronic tag, comprising the following steps of: when service data are stored, reading an 8-digit numerical ID of the RFID electronic tag as a left key of 3DES (Data Encryption Standard); carrying out 3DES encryption operation of data by using an 8-digit numeric string of current time as a right key of the 3DES; then, storing ciphertexts into a databank of a software system by using a 16-digit numeric string comprising the 8-digit numerical ID and the 8-digit numeric string of the current time as a query condition; recording the 8-digit numeric string of the current time in the electronic tag; when the service data are read, taking out the ciphertexts by using the 16-digit numeric string comprising the 8-digit numerical ID of the RFID electronic tag and a stored 8-digit time numeric string as the query condition; and decrypting plaintexts by carrying out the 3DES decryption operation of the ciphertexts by using the 8-digit numerical ID of the RFID electronic tag as the left key and the stored 8-digit time numeric string as the right key. The access method can be used for accessing mass data in the RFID electronic tag.
Description
Technical field
The present invention relates to RFID electronic tag data access method.
Background technology
The RFID electronic tag is the popular call of radio-frequency (RF) identification (RFID), and it is made up of label, plug-in reader and data transmission and disposal system three parts.
Label is also referred to as electronic tag or intelligent label, and it is the chip that internal memory has antenna, store in the chip can recognition objective information.Characteristics such as the RFID label has persistence, and it is strong that message pick-up is propagated penetrability, and the canned data capacity is big, kind is many.Some RFID label is supported read-write capability, and the information of target object can be updated at any time.Plug-in reader is divided into hand-held and fixes two kinds, and by transmitter, receiving instrument, control module and transceiver are formed.Transceiver and control computer or programmable logic controller (PLC) (PLC) thus be connected the communication function of realizing it.Plug-in reader also has antenna to receive and transmission information.Data transmission and disposal system: the radiowave reception reading of data that plug-in reader sends by receiving label.Modal is Passive RFID system, when plug-in reader is met the RFID label, sends electromagnetic wave, form electromagnetic field on every side, label obtains the microchip circuit in the energy activated label from electromagnetic field, chip conversion electromagnetic wave, send to plug-in reader then, plug-in reader converts it to related data.Thereby the control counter just can be handled these data and manage control.In the active rfid system, it is movable in effective range that battery is housed in the label.
The RFID electronic tag has certain data storage capacities, but present electronic tag memory capacity is more limited, particularly the storage space of ultrahigh frequency RFID electronic tag has only the hundreds of data bit, and the cost that the space increases is very high, uses limited storage to seem very important efficiently.
Summary of the invention
Technical matters to be solved by this invention provides the access method of a kind of mass data at the RFID electronic tag, can save finite storage space in the RFID electronic tag, realize the strange land storage of a large amount of electronic tag related service data, and the strange land security of storage data and the integrality that guarantee, help improving the utilization ratio of electronic tag storage space, reduce of the constraint of electronic tag memory capacity the business datum amount.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of mass data is in the access method of RFID electronic tag:
When the storage service data, read the left key of 8 bit digital ID of RFID electronic tag as 3DES, with 8 character strings of current time is that the right key of 3DES carries out the 3DES cryptographic calculation to data, 16 character strings forming with 8 character strings of 8 bit digital ID and current time are that querying condition deposits ciphertext in the software system data storehouse then, and 8 character strings of record current time get final product in electronic tag;
When reading business datum, earlier 16 character strings forming with 8 bit time character strings of 8 bit digital ID of RFID electronic tag and storage are that querying condition takes out ciphertext, 8 bit digital ID with the RFID electronic tag are left key, and to be right key carry out the 3DES decrypt operation to ciphertext can decrypt expressly with 8 bit time character strings of storage.
The beneficial effect that the present invention is compared with prior art brought is:
The storage means of mass data of the present invention in the RFID electronic tag utilized advanced mechanics of communication, computing machine, microelectric technique, REID and network technology, for mass data provides a kind of high-efficiency method in the storage of electronic tag; The storage means of mass data of the present invention in the RFID electronic tag can be saved finite storage space in the RFID electronic tag, realize the strange land storage of a large amount of electronic tag related service data, and the strange land security of storage data and the integrality that guarantee, help improving the utilization ratio of electronic tag storage space, reduce of the constraint of electronic tag memory capacity the business datum amount.

Fig. 2 is the process flow diagram of the storage means reading of data of mass data of the present invention in the RFID electronic tag.
Embodiment
The invention will be further described below in conjunction with Figure of description.
As shown in Figure 1, a kind of mass data is in the access method of RFID electronic tag, when the storage service data, read the left key of 8 bit digital ID of RFID electronic tag as 3DES, with 8 character strings of current time is that the right key of 3DES carries out the 3DES cryptographic calculation to data, 16 character strings forming with 8 character strings of 8 bit digital ID and current time are that querying condition deposits ciphertext in the software system data storehouse then, and 8 character strings of record current time get final product in electronic tag.The memory capacity of RFID electronic tag is limited, and lot of data can't directly be stored.The invention enables no matter great packet is such as the 3K byte, all only take eight bytes, thereby make storage produce a leverage, store lot of data with finite storage space in the storage of electronic tag.
As shown in Figure 2, when reading business datum, read 8 bit digital ID of RFID electronic tag, taking-up is stored in 8 bit time character strings in the electronic tag, and 16 character strings of composition are querying condition, and ciphertext is taken out from the Management System Data storehouse, 8 bit digital ID with the RFID electronic tag are left key, with the 8 bit time character strings of storing in the electronic tag is right key, ciphertext is carried out the 3DES decrypt operation can decrypt expressly, and this expressly be the data that original needs are stored.
The storage means of mass data of the present invention in the RFID electronic tag utilized advanced mechanics of communication, computing machine, microelectric technique, REID and network technology, for mass data provides a kind of high-efficiency method in the storage of electronic tag; The storage means of mass data of the present invention in the RFID electronic tag can be saved finite storage space in the RFID electronic tag, realize the strange land storage of a large amount of electronic tag related service data, and the strange land security of storage data and the integrality that guarantee, help improving the utilization ratio of electronic tag storage space, reduce of the constraint of electronic tag memory capacity the business datum amount.
