Abstract
The present invention relates to a kind of method to NFC label locking, it is characterised in that comprise the following steps: step 1: NFC label be placed into above card reader；Key zone is write the key zone after encryption by step 2:NFC label when initially writing card, and NFC label carries out subregion encryption lock operation；Step 3: now NFC label can only carry out read operation, it is impossible to carry out the operation write；Step 4: be again to carrying out write operation in NFC label.The invention have the advantage that and be written and read card operation in this way, can control accurate to content, label can write the data of arbitrary data types in the past, the label that the mode of this cipher authentication is encrypted is no longer disposable read only tag, but by the way of cipher authentication, label is written and read operation, in the case of cipher authentication and subregion key authentication, only just can change label substance；Improve the encryption level of chip.
Description
Technical field
The present invention relates to a kind of based on the method that NFC label is locked.
Background technology
Existing major part read-write card instrument is substantially based on NDEF (carrying out with nfc label of forum of nfc official definition
A kind of form of information exchange) it is written and read operation, and be merely able to label carry out disposable lock operation, after having locked
Anyone cannot carry out any read-write operation again to label.
Carry out label data is operated by NFED form, be merely able to the standard interface by third party provides and carry out
Reading and writing and locking, this lock mode cannot specifically recognize that bottom locking concrete to label represents the operation of position, and locking is also
Disposably, thus greatly reducing the utilization rate of label, once label is wrongly write and conducts the locking operations, just cannot be to mistake
Content carries out any have changed, and there is the biggest drawback and limitation.
Summary of the invention
For overcoming the defect of prior art, the present invention provides a kind of based on the method locking NFC label.The skill of the present invention
Art scheme is:
A kind of method to NFC label locking, comprises the following steps:
Step 1: NFC label is placed into above card reader；
NFC label by the key zone after key zone write encryption when initially writing card, and is carried out subregion and adds by step 2:NFC label
Close lock operation；
Step 3: now NFC label can only carry out read operation, it is impossible to carry out the operation write；
Step 4: be again to carrying out write operation in NFC label, following manner to be carried out:
1) content of key zone is first read；
2) key is verified:
When key is identical with the key newly read, then reading subregion sign position judgement symbol position, flag bit is 1 directly by content
It is written in the label subregion of correspondence, the operation thus NFC label can be increased, changed；When cipher key content with newly read
Cipher key content identical but time that read subregion sign position is not 1, NFC label can be carried out subregion encryption and more new key
Operation；
When key differs with the key newly read, then cannot be carried out the increasing of label, change operation, flow process directly terminates；
Step 5: repeatedly perform step 1～4 operations, until NFC label is finished completely.
The invention have the advantage that be written and read in this way card operation, can control accurate to content, can mark in the past
Writing the data of arbitrary data types in label, the label that the mode of this cipher authentication is encrypted is no longer disposable read only tag,
But label is written and read operation, by the way of cipher authentication only in the case of cipher authentication and subregion key authentication
Just can change label substance；Improve the encryption level of chip.
Detailed description of the invention
Below in conjunction with specific embodiment further describe the present invention, advantages of the present invention and feature will be with describe and
Apparent.But these embodiments are only exemplary, the scope of the present invention is not constituted any restriction.People in the art
Member it should be understood that to enter the details of technical solution of the present invention and form lower without departing from the spirit and scope of the present invention
Row amendment or replacement, but these amendments and replacement each fall within protection scope of the present invention.
The present invention relates to a kind of method to NFC label locking, it is characterised in that comprise the following steps:
Step 1: NFC label is placed into above card reader；
NFC label by the key zone after key zone write encryption when initially writing card, and is carried out subregion and adds by step 2:NFC label
Close lock operation；
Step 3: now NFC label can only carry out read operation, it is impossible to carry out the operation write；
Step 4: be again to carrying out write operation in NFC label, following manner to be carried out:
1) content of key zone is first read；
2) key is verified:
When key is identical with the key newly read, then reading subregion sign position judgement symbol position, flag bit is 1 directly by content
It is written in the label subregion of correspondence, the operation thus NFC label can be increased, changed；When cipher key content with newly read
Cipher key content identical but time that read subregion sign position is not 1, NFC label can be carried out subregion encryption and more new key
Operation；
When key differs with the key newly read, then cannot be carried out the increasing of label, change operation, flow process directly terminates；
Step 5: repeatedly perform step 1～4 operations, until NFC label is finished completely.
Claims (1)
1. the method to NFC label locking, it is characterised in that comprise the following steps:
