Fig. 2 is the process flow diagram of electronic tag compression of the present invention and encryption method.
[embodiment]
The present invention is further described below in conjunction with description of drawings and embodiment.
Be the module map of electronic labelling system of the present invention as shown in Figure 1.Present embodiment provides electronic tag 1, antenna 3 and read-write equipment 5.The packet 10 of electronic tag 1 is divided into boot section and data field, the boot section by 8 bytes totally 64 form, the data bit of boot section be 1 the expression data field storage data are arranged, data bit be 0 the expression data field do not have data storage.Data field IncFlds byte, data length byte, data division and BCC check code.The packet 10 of electronic tag 1 is through des encryption, and the packet ciphertext that generates equal length stores in the electronic tag 1.
In the present embodiment, the DES algorithm is that the data block of fixed size (64) is carried out the encrypting and decrypting operation, need adopt for those not enough 64 data blocks that to fill machine-processed cover to 64 long, use for convenience, the filling of data bit is transparent for the user, utilize this instrument to carry out encrypting and decrypting when operation, the user only needs information such as filename, the write operation result's of type, the reading of data of input operation filename, key.
In the present embodiment, the key of des encryption is 64, obtains from the user there.Remove in 64 passwords the 8th, 16,24,32,40,48,56,64 as parity check bit, key is effectively imported in 56 remaining conducts.The key of des encryption is managed by read-write equipment.Read-write equipment is read the data of electronic tag storage.
In the present embodiment, the byte quantity of the data length byte of data field is variable.The data implication in each territory is according to the concrete agreement that should be used in the boot section.
Be the process flow diagram of electronic tag compression of the present invention and encryption method as shown in Figure 2.In step S100, whether electronic tag judgment data territory is not empty.
If empty, then return step S100, continue to judge other data field.
If be not empty, then enter step S102, generate the boot section data.
The boot section by 8 bytes totally 64 form, the data bit of boot section be 1 the expression data field storage data are arranged, data bit be 0 the expression data field do not have data storage.
In step S104, adding one by one is not empty data field, generates the data field, with boot section composition data bag, and data field IncFlds byte, data length byte, data division and BCC check code.In the present embodiment, the byte quantity of the data length byte of data field is variable; The data implication in each territory is according to the concrete agreement that should be used in the boot section.
