Description

One-time anti-counterfeiting traceability system based on mobile terminal and RFID

Technical field

The invention relates to the field of commodity anti-counterfeiting technology.

Background technique

With the development of mobile communication technology, especially the development of 2.45GHz radio frequency identification technology and mobile phone short-range wireless communication technology (NFC13.56MHz), the close-range recognition function of mobile phones and mobile terminals is increasingly powerful. The mobile Internet and the Internet of Things are infiltrating into the realm of people's lives. Anti-counterfeiting recognition technology based on this technology emerges in an endless stream. For example, the Chinese patent "a product anti-counterfeiting system based on mobile terminals and RFID electronic tags" is a successful application of the Internet of Things to trace and verify product information through mobile interconnection. This technology has largely prevented counterfeiting and has been successfully applied in practice. Based on RFID electronic tags and mobile Internet, commodity information inquiry and anti-counterfeiting applications are increasingly widespread, and the information security and encryption system of commodity electronic anti-counterfeiting systems are becoming more and more important.

At present, the technical level of counterfeiting is correspondingly improved. The counterfeiters illegally obtain the encrypted authentication data in the electronic tag and illegally copy it through various means such as decryption of the electronic tag, thereby counterfeiting the electronic tag to achieve the purpose of fraud. Therefore, the existing Internet anti-counterfeiting authentication system needs to be improved and improved from the system security.

Summary of the invention

It is an object of the present invention to provide a system solution for efficiently replicating RFID electronic tags by preventing counterfeiters from passing through security holes in electronic tags or security holes in other anti-counterfeiting system components. In order to achieve the unreliable principle of any participant and any device provider used by the system, the entire black box system security architecture is built, and the security of the anti-counterfeiting system is ensured from the overall security architecture of the system.

The technical solution adopted for achieving the object of the present invention is such a one-time anti-counterfeiting traceability system based on mobile terminal and RFID, comprising a system server, an RFID electronic tag disposed on each commodity, and a read/write RFID electronic device. The function of the tag of the mobile terminal device.

Product anti-counterfeiting is achieved through the following process:

1) The message MB _{i,j is} written in the RFID tag on any item. The message MB _i,j is a digital identity certificate for the item. Where i is the serial number of the product, i=1, 2, . . . , n, where j is the number of times the RFID electronic tag is updated and written to the message, j=1, 2, . . . m. The system server stores the message set S={CB _i,1 , CB _i,2 . . . CB _i,j }. The message CB _{i, j} with the message MB _{i, j} corresponding to, and for the message MB _{i, j} for comparison operation, to verify the authenticity of goods. When any item is shipped for the first time, the RFID tag placed on the item is written to MB _i,1 , and the system server stores the message set S={CB _i,1 }, ie j=1.

2) verifying the authenticity of the commodity: after scanning the RFID electronic tag on the commodity to be tested by using the mobile terminal device, transmitting the message X in the read RFID electronic tag to the system server, and the message set S The elements in the pair are compared to verify the authenticity of the item.

Divided into the following three cases:

A) If the comparison operation is performed, the message X does not match any one of the elements of the message set S. The message X is not the message MB _i,j , and the detected item is false, and the system server The mobile terminal transmits the information that the item is false, and ends the authenticity verification operation.

B) if the comparison operation is performed, the message X matches another element of the message set S except the sub-message CB _i,j , the message X is not the message MB _i,j , the system server is to the mobile terminal Send the information that the product is suspicious and true, and end the authenticity check operation.

C) if the comparison operation is performed, the message X matches the message CB _i,j , that is, the message X is the message MB _i,j , and the system server sends the information that the commodity is true to the mobile terminal, and enters Next step.

3) Update certificate: The system server generates a message MB _{i, j+1} and sends it to the mobile terminal. The message MB _{i,j+1 is} written by the mobile terminal into the RFID electronic tag on the item to be tested that has been determined to be true in step 2) to replace the original MB _i,j . The message MB _i,j+1 is a new digital identity certificate representing the commodity, and is used for the next time the user performs authenticity authentication on the commodity. The system server stores the message MB _{i, j + 1} corresponding to the message CB _{i, j + 1,} i.e., the update message set S _{_{{CB i, 1, CB i}} , 2 ...... CB i, j, CB i, j ₊₁ }. The message CB _{i,j+1 is} used for the next comparison operation with the message MB _i,j+1 to verify the authenticity of the commodity.

Further, the relationship between CB _i,j and MB _i,j is one of the following three cases:

a) The CB _i,j is equal to MB _i,j .

b) The CB _i,j is an encrypted message of MB _i,j .

c) The CB _i,j is the hash value after MB _i,j has been hashed.

Further, after the step 3) ends, the message CB _i,j is still stored in the system server. On the premise that the message CB _i,j+1 exists on the system server, the system server receives the to-be-verified message MB _i,k sent by the mobile terminal _{, and} obtains the corresponding CB from MB _i,k _i,k ∈{CB _i,1 , CB _i,2 ......CB _i,j ,CB _i,j+1 } and k≤j, it is judged that the message MB _i,k has been stolen and written In the RFID electronic tag on counterfeit goods. The system server records and submits the scan time and geographic location of the mobile terminal that scans the commodity, and simultaneously invokes and submits the time and geographic location of the mobile terminal scanning the commodity RFID when the system server receives the MB _i,k last time. Provide counterfeiting time and geographical location for counterfeiters for anti-counterfeiting and counterfeiting.

The invention also discloses a combined encryption verification method of one-on-one certificate, that is, a one-word anti-counterfeiting traceability system based on a mobile terminal and an RFID, comprising a system server, an RFID electronic tag disposed on each commodity, and having read and write RFID The electronic terminal functions as a mobile terminal device and a random number generator.

Further, it includes a system server, an RFID electronic tag disposed on each item, a mobile terminal device having a function of reading and writing an RFID electronic tag, and a random number generator.

Product anti-counterfeiting is achieved through the following process:

1) Any item corresponds to a message MA _i , i=1, 2, . . . n composed of serial numbers. The combined message T1 _{i,j is} written into the RFID tag on any item. The combined message T1 _{i,j is a} combination of the message CA _i and the message MB _i,j , ie T1 _i,j =CA _i &MB _i,j , wherein the message CA _i is obtained by performing an encryption operation on the MA _i , ie CA _i = E(MA _i ), the message MB _i,j is a random number generated by the random number generator, as a digital signature certificate of the message MA _i , j is the number of times the RFID electronic tag is updated and written into the message, j=1, 2, ... m.

The system server stores a set of messages S={T2 _i,1 , T2 _i,2 . . . T2 _i,j }, where T2 _i,1 =MA _i &CB _i,1 , T2 _i,2 =MA _i &CB _{i , 1} , T2 _{i, j} = MA _i & CB _{i, j} , the message CB _{i, j} is obtained by performing encryption operation on MB _{i, j} , that is, CB _{i, 1} = H(MB _{i, 1} ), CB _i,2 =H(MB _i,2 ), ...CB _i,j =H(MB _i,j ). The message T2 _{i, j} with the message T1 _{i, j} corresponds to, and a message for T1 _{i, j} for comparison operation, to verify the authenticity of goods. When any item is shipped for the first time, the RFID tag set on the item is written to T1 _i,1 , and the system server stores the message set S={T2 _i,1 }, ie j=1.

2) Verification of the authenticity of the commodity: After scanning the RFID electronic tag on the commodity to be tested by using the mobile terminal device, the message X in the read RFID electronic tag is sent to the system server.

After receiving the message X sent by the reader, the system server first determines whether the format of X is the same as the combined message T1 _i,j . If not, the item to be tested is false, that is, the message X is not the combined message T1 _i,j , and the authenticity verification operation is ended.

If the format of the message X is the same as the combined message T1 _i,j , the message X is split into two parts, XA and XB. The format of the XA is the same as that of the CA _i , and the format of the XB is the same as MB _{i, j} , that is, X= XA&XB. The message XA is decrypted to obtain a value of MXA=E ^-1 (XA). If MXA≠MA _i , the commodity is false, that is, the message X is not the combined message T1 _i,j , and the authenticity verification operation is ended. If MXA=MA _i , find the CB _i,j corresponding to MA _i and perform a one-way function operation on XB to get CXB=H(XB), which is divided into the following three cases:

A) If CXB is not any element of {CB _i,1 , CB _i,2 ... CB _i,j }, message X is not a combined message T1 _i,j , and the detected item is false, the system server The mobile terminal transmits the information that the item is false, and ends the authenticity verification operation.

B) If CXB is any element other than CB _i,j in {CB _i,1 , CB _i,2 ... CB _i,j }, the message X is not the message T1 _i,j , the system server The mobile terminal sends the information that the product is true and false, and ends the authenticity verification operation.

C) If CXB=CB _i,j , the commodity to be tested is genuine, that is, the read message X is a combined message T1 _i,j , and the system server sends the information that the commodity is true to the mobile terminal, and enters Next step.

3) Update the certificate: The system server randomly generates a new random number MB _{i, j+1} . The random number MB _{i,j+1 is} used as a new digital signature certificate for the message MA _i . Transmitting, by the mobile terminal, the message MB _i,j+1 into the RFID electronic tag on the item to be tested that has been determined to be true in step 2) to replace the original combined message T1 _i,j =CA _i &MB _{i ,} MB _{i,j in j} , so that the combined message existing in the RFID electronic tag on the commodity to be tested that has been judged to be true in step 2) is updated to T1 _{i, j+1} = CA _i & MB _{i, j+1} , Used for the next time the user authenticates the item.

At the same time, the system server calculates CB _{i, j+1} = H(MB _{i, j+1} ), forms a new message combination message T2 _{i, j+1} = MA _i & CB _{i, j+1} , and saves it in the office. In the system server, the message set S is updated to {T2 _i,1 , T2 _i,2 ... T2 _i,j , T2 _i,j+1 }. The combined message T2 _{i, j+1 is} used for the next time the user performs authenticity authentication on the item, and performs a comparison operation with the combined message T1 _{i, j+1} to verify the authenticity of the product.

Further, after the step 3) ends, the message T2 _i,j is still stored in the system server. On the premise that the message T2 _{i, j+1} exists on the system server, the system server calculates the to-be-verified message X=XA&XB=CA _i &MB _i,k sent by the mobile terminal. CB _i,k =H(MB _i,k ), if CB _i,k ∈{CB _i,1 , CB _i,2 ......CB _i,j ,CB _i,j+1 } and k≤j, ie It is judged that the message T2 _{i, k} = CA _i & MB _{i, k} has been stolen and written into the RFID electronic tag on the counterfeit item. The system server records and submits the scan time and geographic location of the mobile terminal that scans the commodity, and simultaneously invokes and submits the time and geographic location of the mobile terminal scanning the commodity RFID when the system server receives the MB _i,k last time. Provide counterfeiting time and geographical location for counterfeiters for anti-counterfeiting and counterfeiting.

Further, the pre-written combined message T1 _i,j in the RFID electronic tag on each item has randomness and uniqueness. The CA _i and MB _i,j are not present in the system server after T1 _i,j =CA _i &MB _i,j are written into the RFID electronic tag, and T1 _i,j =CA _i &MB _{i, the} value of _j cannot pass Attack system servers are stolen and copied on a scale.

Further, the length of the message MA _i or MB _i,j is 8 to 1024 bits. The merchandise serial number portion MA _i includes a merchandise production time and a merchandise serial number.

Further, when the commodity is activated, the RFID electronic tag is destroyed. The RFID reader is a mobile phone or mobile terminal with a radio frequency identification function or a short-range wireless communication NFC function.

Further, a part of the bytes in MB _i,j serves as a key for decrypting CA _i .

Further, in the CA _i , a key for decrypting the CA _{i is} implicitly included according to a certain rule.

It is worth noting that the present invention can effectively prevent the electronic tag from being decrypted or being copied by the illegal counterfeiter due to the vulnerability of the tag itself. From the system architecture, the invention innovatively adopts a one-card dynamic signature authentication system. In the system security architecture, messages written to an electronic tag are in a one-time certificate. That is, the initial MB _i,j is stored in the electronic tag at the factory _, and when the user successfully scans the tag to obtain the product information, the server automatically generates a new MB _i,j+1 and calculates a new message CB _i,j+1 . The new message MB _{i+1 is} rewritten into the electronic tag set on the product by the mobile device such as a mobile phone, and the new message CB _{i, j+1} is stored in the system server. The next time you scan the same item, the new MB _{i, j+1} will be read for verification to prevent the label from being cracked and copied.

More preferably, in a preferred form of the invention, the system employs a fault tolerance mechanism to prevent password replacement failures due to network delays or other causes. And the system will make a complete certification record. Once a certain product certification is illegal, it can accurately locate the illegal starting position and possible geographical area.

detailed description

The invention is further illustrated by the following examples, but it should not be understood that the scope of the invention described above is limited to the following examples. Various changes and modifications may be made without departing from the spirit and scope of the invention.

Example 1:

A one-pass anti-counterfeiting traceability system based on a mobile terminal and an RFID, comprising a system server, an RFID electronic tag disposed on each item, and a mobile terminal device having a function of reading and writing an RFID electronic tag.

Anti-counterfeiting of goods through the following steps:

1) The message MB _{i,j is} written in the RFID tag on any item. The message MB _i,j is a digital identity certificate for the item. Where i is the serial number of the product, i=1, 2, ..., n, j is the number of times the RFID electronic tag writes the message, that is, the number of times the RFID electronic tag is updated and written to the message, j=1, 2, . . . m . The system server stores the message set S={CB _i,1 , CB _i,2 . . . CB _i,j }. The message CB _{i, j} with the message MB _{i, j} corresponding to, and for the message MB _{i, j} for comparison operation, to verify the authenticity of goods. When any item is shipped for the first time, the RFID tag placed on the item is written to MB _i,1 , and the system server stores the message set S={CB _i,1 }, ie j=1. For example, a message MB _1,1 is written in an RFID electronic tag, which is the first time the message is written into the RFID tag. The message written in the RFID tag on the commercially available authenticity will be the message set {MB _1,1 , MB _2,1 ,...,MB _n,1 ,...MB _1,2 ,MB _2,2 ,... ..., MB _{n, 2} , ... MB _{1, m} , MB _{2, m} , ... MB _{n, m} }.

The system server stores the message MB _{i, j} corresponding message CB _{i, j.} That is, the system server stores the message set as belonging to or equal to {CB _1,1 , CB _2,1 , . . . , CB _n,1 , . . . CB _1,2 , CB _2,2 , . . . , CB _n,2 , ...CB _1,m ,CB _2,m ,...CB _n,m }. The message CB _{i,j is} used for comparison with the message MB _i,j to verify the authenticity of the commodity.

In an embodiment _, the relationship between CB _i,j and MB _i,j is one of the following three cases: a) the CB _i,j is equal to MB _i,j . b) The CB _i,j is an encrypted message of MB _i,j . c) The CB _i,j is the hash value after MB _i,j has been hashed.

2) Verification of the authenticity of the product: After the RFID electronic tag on the product to be tested is scanned by using the mobile terminal device, the RFID electronic tag may also be an electronic tag on the authentic product, or may be an electronic tag on the counterfeit product. Transmitting the message X in the read RFID electronic tag to the system server, and performing a comparison operation with the message stored in the system server to verify that the commodity is authentic (ie, the message X may be a real message) MB _i,j may or may not be required by the system server).

Divided into the following three cases:

B) if the comparison operation is performed, the message X matches another element of the message set S other than the message CB _i,j , the message X is not the message MB _i,j , and the system server sends the message to the mobile terminal The product is suspicious and the end of the authenticity verification operation.

C) if the comparison test is performed to verify that the item to be tested is true, the message X matches the message CB _i,j , that is, the message X is the message MB _i,j , and the system server sends the message to the mobile terminal The goods are true information and go to the next step.

The specific implementation of this embodiment can also be illustrated by the following example:

A manufacturer has a total of 10 items shipped. 10 items were posted with messages MB _1,1 , MB _2,1 , MB _3,1 , MB _4,1 , MB _5,1 , MB _6,1 , MB _7,1 , MB _{8 respectively . 1, 1} , MB ₉ _{, 1} and MB _{10, 1} RFID electronic tags. Specifically, MB _1,1 =101, MB _2,1 =102, MB _3,1 =103, MB _4,1 =104, MB _5,1 =105, MB _6,1 =106, MB _7,1 = 107, MB ₈ , ₁ = 108, MB ₉ , ₁ = 109, MB ₁₀ , ₁ = 110.

The system server stores a message set S={CB _1,1 , CB _2,1 , . . . , CB _10,1 } for verifying the authenticity of the above 10 items. Among them, the message CB _1,1 is the hash value of the message MB _1,1 , the message CB _2,1 is the hash value of the message MB _2,1 , ... the message CB _10,1 is the hash of the message MB _10,1 Value, and so on.

After the consumer scans the RFID electronic tag on the product to be tested by using the mobile terminal device, the RFID electronic tag may also be an electronic tag on one of the above 10 genuine products, or may be an electronic tag on the counterfeit product.

If the message X=200 in the RFID electronic tag read by the mobile terminal is sent to the system server, after receiving the message X=200, the system server performs a hash operation on the obtained message. The hash value does not belong to the message set S, that is, it is determined that the item to be tested is not one of the above 10 pieces of genuine products. The system server sends the information that the commodity is false to the mobile terminal, and ends the authenticity verification operation.

If the mobile terminal reads the message X=101 in the RFID electronic tag and sends it to the system server, the system server receives the message X=101, and then hashes it to obtain The hash value belongs to the message set S, that is, it is determined that the commodity to be tested is one of the above 10 genuine products. The system server sends the information to the mobile terminal as authentic, and enters the operation of updating the certificate: the system server generates a message MB _{1, 2} = 1011 and sends it to the mobile terminal, through which the mobile terminal will The message MB _{1, 2} = 1011 is written in the RFID electronic tag on the item that has been judged to be genuine, that is, the original message MB _1,1 =101 in the RFID tag of the product is replaced by MB _1,2 =1011. At the same time, the system server will increment the hash value "message CB _1,2 " of the message MB _1,2 in the message set S.

After the consumer again scans the RFID electronic tag on the item using the mobile terminal device, the mobile terminal will message X=1011. The system server hashes the message X=1011, and the obtained hash value is “message CB _1,2 ”, which belongs to the message set S, and determines that the commodity is one of 10 genuine products. The system server sends the information to the mobile terminal as authentic, and enters the operation of updating the certificate again: the system server generates a message MB _{1, 3} = 10111 and sends it to the mobile terminal through the mobile terminal The message MB _1,3 = 10111 is written into the RFID electronic tag on the item that has been judged to be genuine, that is, the original message MB _1,2 = 1011 in the RFID tag of the product is replaced by MB _1,3 = 10111. At the same time, the system server will increment the hash value "message CB _1,3 " of the message MB _1,3 in the message set S.

......

If the system server receives the message MB _1,1 =101 sent by the mobile terminal more than once, and there is not only CB _{1,1 in the} system server, but also CB _1,2 , CB _1,3 ... CB _1,m One or more of them. That is, it is judged that the message MB _1,1 has been stolen and written into the RFID electronic tag on the counterfeit goods. The system server records the scan time and the geographical location of the mobile terminal of the previously transmitted message MB _1,1 =101, that is, the anti-counterfeiting anti-counterfeiting provides the counterfeiting time and geographical location of the counterfeiter.

Example 2

This embodiment is a preferred mode of Embodiment 1, and further includes a random number generator for implementing combined encryption authentication of the commodity.

A one-pass anti-counterfeiting traceability system based on a mobile terminal and an RFID, comprising a system server, an RFID electronic tag disposed on each item, a mobile terminal device having a function of reading and writing an RFID electronic tag, and a random number generator.

Anti-counterfeiting of goods through the following steps:

The system server stores a set of messages S={T2 _i,1 , T2 _i,2 . . . T2 _i,j }, where T2 _i,1 =MA _i &CB _i,1 , T2 _i,2 =MA _i &CB _{i , 1} , T2 _{i, j} = MA _i & CB _i,j , the message CB _i,j is obtained by performing an encryption operation on MB _i , that is, CB _i,1 =H(MB _i,1 ), CB _{i, 2} = H(MB _{i, 2} ), ... CB _{i, j} = H(MB _{i, j} ). In an embodiment, y = H(x) may be a one-way function. The message T2 _{i, j} with the message T1 _{i, j} corresponds to, and a message for T1 _{i, j} for comparison operation, to verify the authenticity of goods. When any item is shipped for the first time, the RFID tag set on the item is written to T1 _i,1 , and the system server stores the message set S={T2 _i,1 }, ie j=1.

For example, a message T1 _1,1 is written in an RFID tag, which is the first time a message is written into the RFID tag. The message written in the RFID tag on the commercially available authenticity will be the message set {T1 _1,1 , T1 _2,1 ,...,T1 _n,1 ,...T1 _1,2 , T1 _2,2 ,... ..., T1 _{n, 2} , ... T1 _{1, m} , T1 _{2, m} , ... T1 _{n, m} } A value.

The system server stores a message T2 _i,j corresponding to the message T1 _i,j . That is, the system server stores the message set as belonging to or equal to {T2 _1,1 , T2 _2,1 , . . . , T2 _n,1 , . . . T2 _1,2 , T2 _2,2 , . . . , T2 _{n, 2} , ... T2 _1,m , T2 _2,m ,...T2 _n,m }. The message T2 _{i,j is} used for comparison with the message T1 _i,j to verify the authenticity of the commodity.

If the format of the message X is the same as the combined message T1 _i,j , the message X is split into two parts, XA and XB. The format of the XA is the same as that of the CA _i , and the format of the XB is the same as MB _{i, j} , that is, X= XA&XB. Decrypting the message XA to obtain a value MXA=E ^-1 (XA), y=E(x) is an encryption function, and y=E ^-1 (x) is a decryption function corresponding to y=E(x) . If MXA≠MA _i , the item is false, that is, message X is not combined message T1 _i,j , and the authenticity check operation is ended. If MXA=MA _i , find the CB _i,j corresponding to MA _i and perform a one-way function operation on XB to get CXB=H(XB), which is divided into the following three cases:

3) Update the certificate: The system server randomly generates a new random number MB _{i, j+1} . The random number MB _{i,j+1 is} used as a new digital signature certificate for the message MA _j . Transmitting, by the mobile terminal, the message MB _i,j+1 into the RFID electronic tag on the item to be tested that has been determined to be true in step 2) to replace the original combined message T1 _i,j =CA _i &MB _{i ,} MB _{i,j in j} , so that the combined message existing in the RFID electronic tag on the commodity to be tested that has been judged to be true in step 2) is updated to T1 _{i, j+1} = CA _i & MB _{i, j+1} , Used for the next time the user authenticates the item.

At the same time, the system server calculates CB _{i, j+1} = H(MB _{i, j+1} ), forms a new message combination message T2 _{i, j+1} = MA _i & CB _{i, j+1} , and saves it in the office. In the system server, the message set S is updated to {T2 _i,j , T2 _i,2 . . . T2 _i,j , T2 _i,j+1 }. The combined message T2 _{i, j+1 is} used for the next time the user performs authenticity authentication on the item, and performs a comparison operation with the combined message T1 _{i, j+1} to verify the authenticity of the product.

As a preferred mode of this embodiment, after the step 3) ends, the message T2 _i,j is still stored in the system server. On the premise that the message T2 _{i, j+1} exists on the system server, the system server calculates the to-be-verified message X=XA&XB=CA _i &MB _i,k sent by the mobile terminal. CB _i,k =H(MB _i,k ), if CB _i,k ∈{CB _i,1 , CB _i,2 ......CB _i,j ,CB _i,j+1 } and k≤j, ie It is judged that the message T2 _{i, k} = CA _i & MB _{i, k} has been stolen and written into the RFID electronic tag on the counterfeit item. The system server records and submits the scan time and geographic location of the mobile terminal that scans the commodity, and simultaneously invokes and submits the time and geographic location of the mobile terminal scanning the commodity RFID when the system server receives the MB _i,k last time. Provide counterfeiting time and geographical location for counterfeiters for anti-counterfeiting and counterfeiting.

Product anti-counterfeiting is achieved through the following process:

1) Any one item corresponds to a message MA i , i=1, 2, . . . n composed of serial numbers; in the RFID electronic tag on any item, the combined message T1 i,j is written; the combined message T1 i,j is a combination of the message CA i and the message MB i,j , ie T1 i,j =CA i &MB i,j , wherein the message CA i is obtained by performing an encryption operation on the MA i , ie CA i = E(MA i ), the message MB i,j is a random number generated by the random number generator, as a digital signature certificate of the message MA i , j is the number of times the RFID electronic tag is updated and written into the message, j= 1, 2, ... m;

The system server stores a set of messages S={T2 i,1 , T2 i,2 . . . T2 i,j }, where T2 i,1 =MA i &CB i,1 , T2 i,2 =MA i &CB i , 2 , ... T2 i, j = MA i & CB i,j , the message CB i,j is obtained by performing an encryption operation on MB i,j , ie CB i,1 =H(MB i,1 ), CB i,2 =H(MB i,2 ), ...CB i,j =H(MB i,j ); the message T2 i,j corresponds to the message T1 i,j for the sum message T1 i, j performs a comparison operation to verify the authenticity of the commodity; when any product is shipped for the first time, the RFID electronic tag set on the commodity is written to T1 i,1 , and the system server stores the message set S={T2 i , 1 }, ie j=1;

2) verifying the authenticity of the commodity: after scanning the RFID electronic tag on the commodity to be tested by using the mobile terminal device, transmitting the message X in the read RFID electronic tag to the system server;

After receiving the message X sent by the reader, the system server first determines whether the format of the X is the same as the combined message T1 i,j ; if not, the product to be tested is false, that is, the message X is not the combined message T1 i, j , end the authenticity verification operation;

If the format of the message X is the same as the combined message T1 i,j , the message X is split into two parts, XA and XB. The format of the XA is the same as that of the CA i , and the format of the XB is the same as MB i, j , that is, X= XA&XB; decrypting the message XA to obtain the value MXA=E -1 (XA), if MXA≠MA i , the commodity is false, that is, the message X is not the combined message T1 i,j , and the authenticity verification operation is ended; If MXA=MA i , find the CB i,j corresponding to MA i and perform a one-way function operation on XB to get CXB=H(XB), which is divided into the following three cases:

A) If CXB is not any element of {CB i,1 , CB i,2 ... CB i,j }, message X is not a combined message T1 i,j , and the detected item is false, the system server The mobile terminal sends the information that the commodity is false, and ends the authenticity verification operation;

B) If CXB is any element other than CB i,j in {CB i,1 , CB i,2 ... CB i,j }, the message X is not the message T1 i,j , the system server The mobile terminal sends the suspicious information of the commodity, and ends the authenticity verification operation;

C) If CXB=CB i,j , the commodity to be tested is genuine, that is, the read message X is a combined message T1 i,j , and the system server sends the information that the commodity is true to the mobile terminal, and enters Next step;

3) updating the certificate: the system server randomly generates a new random number MB i, j+1 ; the random number MB i, j+1 is used as a new digital signature certificate of the message MA i ; message MB i, j + 1 has been written in step 2) is true is determined on the RFID tag test product in order to replace the original message composition T1 i, j = CA i & MB i, j of the MB i , j , so that the combined message existing in the RFID electronic tag on the item to be tested that has been determined to be true in step 2) is updated to T1 i, j+1 = CA i & MB i, j+1 for the next time the user pairs This item is used for authenticity authentication;

At the same time, the system server calculates CB i, j+1 = H(MB i, j+1 ), forms a new message combination T2 i, j+1 = MA i & CB i, j+1 , and saves in the In the system server, the message set S is updated to {T2 i,1 , T2 i,2 . . . T2 i,j , T2 i,j+1 }; the combined message T2 i,j+1 is used for the user The next time the product is authenticated, it is compared with the combined message T1 i, j+1 to verify the authenticity of the product.
