Abstract
Aiming at the possibility that user data can be stolen illegally to produce heavy losses in the RFID (Radio Frequency Identification Device) label read-write process, the invention provides a method for enhancing radio-frequency identification information safety and privacy protection and belongs to the technical field of wireless radio-frequency. The method is characterized in that ECC (Error Correction Code)or PCF (Physical Unclonable Functions) circuit authentication is adopted between a reader-writer and labels and RSA (Rational Software Architect) or ECC authentication technology is adopted between the reader-writer and a back end data base to protect communication; as for the authorization access, the labels can be accessed and the back end data base can be queried only by the reader-writer being subjected to legal authentication; the reader is authenticated by the back end data base; traditional public key based authentication method is adopted between the back end data base and the reader; and only legal labels can be acquired by the legal reader-writer or can update status information in the identification of the labels. The method has the advantage that in conventional RFID label read-write, the defect that the RFID label can respond the reader-writer directly without the permission of the owner to query and steal the existent user data which results in the possibility of heavy losses and the like can be overcome.
Description
Technical field
The present invention is directed to the RFID(radio-frequency (RF) identification) user data can illegally be usurped the possibility that produces heavy losses in the label read-write process, has proposed a kind of method that strengthens information in radio frequency safety and secret protection, belongs to the wireless radio-frequency field.
Background technology
Internet of Things (Internet of things) is the important trend of present information networking development, is called as computing machine, the internet third wave of world's information industry afterwards, and radio RF recognition technology RFID is one of Internet of Things gordian technique.The RFID technology is a kind of contactless automatic identification technology, it is identified destination object automatically and obtains related data by radiofrequency signal, but, distance strong with its identification radio read-write, signal penetration capacity, long service life, good environmental adaptability, can many labels identify simultaneously, the information storage easily big and data advantage such as can rewrite, be used widely in recent years.
When existing RFID label is read and write, the RFID label does not need just directly to respond through its owner's permission the inquiry of read write line, do not have the user to be read by near read write line under the situation of perception, exist user data can illegally be usurped the possibility that produces heavy losses.Perhaps reveal individual's sensitive information, particularly may expose user's location privacy, make the user tracked.In addition, after label information is read, itself also exist to be replicated or the risk of " clone ".
Summary of the invention
The purpose of this invention is to provide a kind of method that strengthens information in radio frequency safety and secret protection; when solving existing RFID label read-write, do not inquire about existing user data and can illegally be usurped the deficiencies such as possibility that produce heavy losses because the RFID label does not need to allow just directly to respond read write line through its owner.
The objective of the invention is to be achieved through the following technical solutions, a kind of method that strengthens information in radio frequency safety and secret protection is characterized in that, described method is the authentication of granted access and label; Described granted access, have only read write line ability access tag, inquiry back-end data base through legal authentication, back-end data base authenticates reader, adopt tradition based on the authentication method of PKI between back-end data base and the reader, as the authentication based on RSA or ECC, also can adopt the authentication based on symmetric key; The authentication of described label has only legal label just can be obtained by legal read write line or update mode information, thereby can prevent bootlegging or " clone's " label.
The authentication of described label can be adopted the authentication based on ECC, also can adopt PCF(Physical Unclonable Functions) circuit realizes the uniqueness of label.
Described PCF circuit refers to that there is the difference of inevitable technological parameter in the chip production process, extract the difference parameter that produces in the chip manufacturing proces, generate a plurality of, unique, uncertain challenge responses is right, be stored in back-end data base, during each authenticating tag, select a challenge message to send to label, make the authentication to label after then the response message of the response message of label and storage being compared, in order to guarantee privacy, the reader end need be right to the enough challenge responses of each tag storage, challenge response between reader and the label can have strict time restriction, attacks thereby resist possible third party.
The present invention is by increasing the mode of granted access, to adopting ECC or PCF(Physical Unclonable Functions between read write line and the label) adopt RSA or ECC authentication techniques to protect communicating by letter between circuit authentication, read write line and the back-end data base, have only through the read write line of legal authentication could access tag, the inquiry back-end data base; Described granted access, have only read write line ability access tag, inquiry back-end data base through legal authentication, back-end data base authenticates reader, adopt tradition based on the authentication method of PKI between back-end data base and the reader, as the authentication based on RSA or ECC, also can adopt the authentication based on symmetric key; The authentication of described label has only legal label just can be obtained by legal read write line or update mode information, thereby can prevent bootlegging or " clone's " label.When having solved the read-write of existing RFID label, do not inquire about existing user data and can illegally be usurped the deficiencies such as possibility that produce heavy losses because the RFID label does not need to allow just directly to respond read write line through its owner.
Embodiment
Further specify the present invention in conjunction with the embodiments, back-end data base authenticates read write line, adopt tradition based on the authentication method of PKI between back-end data base and the read write line, comprise the authentication based on RSA or ECC, also can adopt the authentication mode based on symmetric key.
Authentication between read write line and the label comprises the authentication based on ECC, and PCF circuit authentication cheaply.The PCF authentication refers to that there is inevitable technologic nuance in the chip production process, the characteristic that these differences have is unpredictable, can not imitate and copy, even the manufacturer of chip also can not copy identical difference parameter from the another one chip, this unique trait of chip can be used as the anti-clone's of chip function: the difference of extracting inevitable generation in the chip manufacturing proces, generate a plurality of, unique, uncertain challenge responses is right, is stored in back-end data base.During each authenticating tag, select a challenge message to send to label, make the authentication to label after then the response message of the response message of label and storage being compared.In order to guarantee privacy, reader need be right to the enough challenge responses of each tag storage, to satisfy a large amount of label authentication needs.
In addition, in order further to strengthen the safety of the challenge response between reader and the label, can strictness limit the time of challenge response, attack thereby resist possible third party.Have only legal label just can be obtained by legal read write line or update mode information.Thereby can prevent bootlegging or " clone's " label.
