Abstract
The invention discloses a method for generating an ID code on the basis of encryption calculation of a TID code and an EPC. The encryption calculation is finished in an RFID (radio frequency identification device) reader-writer, and the obtained ID code can be applied to multiple fields, for example, all systems of a security and protection system, a stored-value system and the like, which require ID confirmation. According to the method for generating the ID code on the basis of encryption calculation of the TID code and the EPC, a unique TID code in an RFID tag is taken as a secret key, one ID code is generated through encryption calculation of the EPC code, and the ID code is unique and obtained through encryption calculation. The method has the advantages that even if the EPC code and TID code of the RFID tag are intercepted by a third party or the EPC code is replicated, one ID code which is identical to the ID code obtained through encryption calculation is impossible to generate, the uniqueness of ID code comes into existence unless the TID code loses uniqueness, and the safety of a system requiring identity recognition is improved.

The TID code is the global unique ID number be comprised of some bytes that chip manufacturer is solidificated in the ROM the inside while dispatching from the factory.The TID code does not need password directly with read write line, to read.If select the TID code, although the TID code has uniqueness, can be used for representative and the identification of identity, because TID code book body 8 byte information can't its revised context, so caused equally the limitation of application.
With the RFID electronic tag in USER district, although need password authentification when read-write, not every label all is with the USER district on the one hand; When read write line and label carried out air communication, the password of checking use was was easily intercepted and captured and is cracked by the third party on the other hand, and this has equally also reduced the safety in utilization of label as identification ID.Simultaneously, when many labels were read to the USER district, operating speed was slower, and the encryption be not suitable under intensive label condition is read.
The ultrahigh frequency RFID electronic tag, be to use the EPC code as plain code, and the TID code is as manufacturer, and the USER district is as the privately owned district that reads and writes data of user (just can complete read-write with password authentification) and the electronic tag of making.With the ultrahigh frequency RFID electronic tag, replace traditional IC-card to carry out empowerment management in security system etc. needs the field of identification, have distance sensing to read, facilitate user's characteristics.The mode of application is mainly at present: using the EPC code as unique identification, or using the USER district as unique identification, or using the TID code as unique identification, carry out ID code sign, but all have the possibility that is replicated or is intercepted and captured, thereby security of system was lost efficacy.In view of above analysis, need to carry out to the ID code occasion of identity validation, the application of RFID technology need to have special means to realize.
Summary of the invention
For solving the problems of the technologies described above, the object of the present invention is to provide a kind of ID code safety that can guarantee that rfid system provides unique, and calculate based on TID code and EPC code encryption the method that produces the ID code.
For achieving the above object, the invention provides following technical scheme: a kind of method based on TID code and EPC code encryption calculating generation ID code, this computations completes in rfid interrogator inside, it is characterized in that, the method that described computations produces the ID code comprises the following steps:
(a) rfid interrogator is to RFID electronic tag inquiry TID code and EPC code;
(b) the RFID electronic tag is replied TID code and EPC code to rfid interrogator;
