Further, the electronic tag may be an RFID (Radio Frequency Identification) electronic tag, and the RFID electronic tag is provided with a plurality of blocks (block areas) for writing product information or logistics information respectively; and has been written into the RFID electronic tag. Product information and logistics information can only be read by combining the corresponding key.

The RFID electronic tag includes an analog front end and an AES module; the AES module includes a controller, a RAM module, and a data path; a sub-module is built in the data path, and the sub-module performs only one-quarter of the MixColumns operation, as shown in FIG. And Figure 4 shows.

The authentication process for RFID electronic tags involves an authentication server, an authentication reader, and an authentication tag (ie, an RFID tag). Referring to FIG. 5-a, the encryption unit of the authentication server includes an XOR execution unit 201. The XOR execution unit 201 performs an XOR operation on the 0 to 15 bits of the acknowledgment data 203 and the output key 205 to be encrypted, through the bit unit for generating the cryptographic confirmation data 207. The encryption confirmation data 207 is transmitted to the authentication reader together with the input key (InputKey_RN), and the confirmation data 207 and the input key (InputKey_RN) transmitted to the authentication reader are generated as one message and transmitted to the authentication tag.

As shown in FIG. 5-b, the decryption unit of the authentication tag (ie, the RFID electronic tag) includes an XOR execution unit 211. The XOR execution unit 211 performs an XOR operation with respect to bits 0 to 15 of the output key 215 and the encryption confirmation data 213 included in the Sec_Auth command message, and the unit 217 is configured to generate decryption confirmation data. In this case, the output key 215 is used by the key processor of the authentication tag to use the input key (InputKey_RN) included in the Sec_Auth command message and the AES key included in the authentication memory.

Further, as shown in FIG. 5-c, the encryption unit of the authentication tag includes an XOR execution unit 221. The XOR execution unit 221 performs XOR on the acknowledgment data 223 to be encrypted and the bits 16 to 31 of the output key 225, and performs an XOR operation in bit units to generate cryptographic confirmation data 227. In this case, the confirmation data 223 to be encrypted may be the confirmation data 217 decrypted from the decryption unit of the authentication tag. Therefore, the XOR execution unit 221 re-encrypts the decrypted confirmation data 217 to generate the encrypted confirmation data 227.

The encryption confirmation data 227 is composed of a Sec_auth response message and is sent to the authentication reader. Further, the confirmation data 227 sent to the authentication reader is transmitted to the authentication server.

Further, as shown in FIG. 5-d, the decryption unit of the authentication server includes an XOR execution unit 231. The XOR execution unit 231 performs an XOR operation on the bits 16 to 31 of the encryption confirmation data 233 and the output key 235, and generates decrypted confirmation data 237 in units of bits.

Subsequently, the authentication server compares the confirmation data 203 generated in the authentication server with the decryption confirmation data 237 received from the authentication reader, thereby verifying the authenticity of the authentication tag.

6 is a block diagram of a configuration of an RFID authentication system having an authentication function. The RFID authentication system includes an authentication server 301, an authentication reader 321 and an authentication tag 331; the authentication server 301 includes a key database 302, a key processor 303, an authentication data generator 304, an encryption unit 305, a tag authentication unit 306, and a decryption unit 307.

When receiving the authentication information from the authentication reader 321, the key processor 303 uses the authentication information to determine the AES key. Here, the authentication information includes an electronic product code (EPC) and SecParam. That is, the key processor 303 determines the AES key corresponding to the AES key index of the SecParam in the key database 302.

Subsequently, the key processor 303 generates an output key by using an AES key and an input key (InputKey_RN) randomly generated in the authentication server 301. In this case, the input key (InputKey_RN) can be a public key.

The confirmation data generator 304 generates confirmation data of a predetermined length, and encrypts the confirmation data by using the encryption unit 305. Subsequently, the confirmation data generator 304 transmits the input key and the encryption confirmation data to the authentication reader 321. Here, the encryption unit 305 performs exclusive OR (XOR) for the confirmation data and the output key for encrypting the confirmation data.

Upon receiving the encrypted acknowledgment response data from the authentication reader 321, the tag authentication unit 306 decrypts the encrypted acknowledgment response data by using the decryption unit 307, and compares the acknowledgment data with the decrypted acknowledgment response data to verify the authentication tag 331. The authenticity, that is, when the confirmation data and the decrypted confirmation response data are the same, the authentication tag 331 is authenticated by the authentication reader 321 , and therefore, the tag authentication unit 305 verifies that the authentication tag 331 is authentic, indicating that the authentication tag 331 is Produced by legal producers. On the contrary, when the confirmation data and the decrypted confirmation response data are different, the authentication reader 321 does not authenticate the authentication tag 331, so the tag authentication unit 305 verifies that the authentication tag 331 is not authentic, indicating that the authentication tag 331 is not generated by the legal producer. . Subsequently, the tag authentication unit 305 can transmit the authentication result to the authentication reader 321. Here, the decryption unit 307 can perform XOR on the encrypted acknowledgment response data and the output key for decrypting the encrypted acknowledgment response data.

Therefore, the encryption unit 305 performs XOR on the input data by using the output key, and performs an encryption key on the input data in the same manner as the decryption unit 307 performs XOR with respect to the input data using the output to decrypt the input data, and thus, the encryption unit 305 and The decryption unit 307 can have the same structure.

The authentication reader 321 may further include an authentication information transmission unit 323 and an acknowledgment information transmission unit 325.

The authentication information transmission unit 323 transmits a part of the authentication information when receiving the authentication information from the authentication tag 331. Here, the authentication information includes Protocol Control (PC), Extended Protocol Control (XPC), EPC, and a SecParam.

In this case, the authentication information transmission unit 323 can receive the PC, XPC, EPC, and SecParam transmitted after the ST bit of the XPC is identified as T through the authentication tag 331.

Further, the authentication information transmission unit 323 first receives the PC, XPC and EPC in the authentication information, and the authentication information transmitting unit 323 determines that the ST bit XPC of the authentication information transmitting unit 323 is identified as "1". Subsequently, the authentication information transmission unit 323 can receive the SecParam from the authentication tag 331 by using the Get_SecParam command and the response message.

Further, in the receiving phase, after receiving the parcel, the consignee first confirms whether the parcel has physical damage, and if there is physical damage, it can directly reject the product, that is, the traceability of the product fails, otherwise the RFID is read through the assigned public key. The goods information or logistics information in the electronic label will be signed after confirmation.

In the delivery phase, the package information can also be uploaded for receipt. The party compares the packaging information at the time of receipt to further verify the goods.

It should be noted that the blockchain has the self-checking function of the node: the blockchain uses the blockchain structure to store the data record, and the modification of the partial record destroys the integrity of the blockchain structure, and can be quickly verified and from other nodes. Restore the data. In addition, each billing node of the blockchain has its own private key, and each block header contains the signature of the private key of the node, and the modification of the data in the block can be verified by the signature;

The blockchain also has a multi-node quasi-real-time data check function: when the private key of the node is stolen, the malicious user has the possibility of modifying all the data on the ledger chain, and the blockchain provides quasi-real-time between multiple nodes. The data comparison mechanism can timely find out that a certain node's account book data has been tampered with.

User information and blockchain addresses in the blockchain are isolated. From the record storage of each node, the associated user information cannot be obtained. User information storage has multiple layers of protection such as access control, access authentication, and encrypted storage. Users with higher transaction confidentiality can also choose the transaction irrelevance mechanism. Each transaction of the same user is mapped to different addresses on the blockchain, thus ensuring that multiple users of a user cannot be obtained on the transaction book. The relevance of the transaction.

In the key management solution of the blockchain, a key safe and a user account delegation function are provided to ensure the security of the key. The key safe uses the user information to encrypt and divide the key and store it on multiple different nodes. The key safe is not accessed under the normal business process. After the user key is lost, the key can be found after the user information is authenticated. return. The account entrustment is to realize the account retrieving function by entrusting the account to operate the entrusted account. All the entrusted account operations in the blockchain are independently recorded on the blockchain, and the operation of the entrusted account has strict frequency restriction and independent. The risk control strategy can strictly control the operational risk of the entrusted account.

In one embodiment, as shown in FIG. 13, the tamper device 500 includes a mechanical tamper device 510 disposed at the opening of the package of the packaged goods, and the electronic tag 200 is located in the mechanical tamper device 510. The mechanical tamper device 510 destroys the electronic tag 200 when the package opening is opened.

The cargo traceability anti-counterfeiting device of the embodiment of the present invention corresponds to the above-mentioned product traceability anti-counterfeiting method, and the technical features and the beneficial effects thereof described in the embodiment of the above-described cargo traceability anti-counterfeiting method are applicable to the embodiment of the cargo traceability anti-counterfeiting device.

In one embodiment, the item traceability anti-counterfeiting method can be applied to a scene of logistics transportation.

The packaged goods are registered into the account book server produced by the blockchain technology. When the delivery order is issued, the blockchain issues a delivery statement to the designated carrier link, and each carrier confirms the receipt in the respective blockchain account. Goods and parcels that continue to be shipped as a technical unit. At the same time, the AES continuous key is authenticated by the blockchain server and passed to the link one by one. For example, after the first carrier authenticates the identity through the blockchain, the blockchain server transmits the holding sequence key N and uses the key. After a write operation, the blockchain server will recognize the transfer of the carrier responsibility and will abolish the key seal and issue the consecutive key N+1 that the next carrier should hold on the next link.

Each time a carrier is changed in the transport path, the carrier writes the RFID chip with the phase key N+X held by him, and writes the carrier's receiver information (such as identification number, GPS information, receiving goods). Operator, license plate number, time, etc.) to the specified block, and write the operation to its own blockchain server account, recognize the occurrence of its own responsibility, form a blockchain accounting contract mechanism, and synchronize the upstream and downstream data of the ledger.

When the parcel is delivered to the final consignee, the consignee has received the delivery statement and the consignee key B from the consignor's blockchain server, and the consignee can register with the card reader held by the consignee. The terminal with the identity binding reads the encrypted data on the RFID chip and interprets it, and reads all the information of the consignor and the carrier information on the terminal. After the confirmation information is correct, the actual temporary key B and the key A and the carrier continuous key N, N+1...N+X are simultaneously invalidated after the customer receives the goods, and are The mark is invalid and cannot be reused for a limited period of time, and these keys will be cancelled after the expiration date.

Previously, it is inevitable that both the carrier and the final consignee should check the packaging intact to judge whether the packaged goods are received by the most traditional rules. If the packaging is intact, further read the chips that have not been destroyed. If the packaging is damaged, you can investigate the transportation and storage responsibility of the packaged goods without having to read the chip.

The chip is protected by the outer packaging and its own protection device during transportation. If the chip is damaged, it means that the packaging is damaged or the chip protection device is violently destroyed, or the package is opened in the middle. Any state occurs, which means The carrier violates the carrier’s liability or is liable for damage to the parcel, and our system limits the carrier’s liability to the current carrier. The next carrier refuses to accept the goods and marks the parcel goods as current carrier liability in the blockchain and announces them to the upstream and downstream links. At this time, the consignor will know the abnormal situation, the parcel goods will be handled abnormally and the responsibility will be clearly defined. The bearer, the final consignee will not be damaged or unpacked parcels.

Such a rule guarantees the end-to-end integrity of the technical unit under the protection of the AES encryption protection and the RFID protection device as a blockchain accounting, so that the packaged goods cannot be replaced in the middle, avoiding The generation of intermediate fakes accurately locates the ultimate responsible person of the packaged goods.

Logically, each package has become a non-counterfeit, data-unchangeable, and directional IoT offline mobile technology unit. This technology unit transfers the responsibility through the blockchain accounting mechanism. The responsibility for the preservation changes as the technical unit registers in the path, forming a blockchain contract.

In the specific application, as shown in FIG. 14, in the process 1, if there is an e-commerce order corresponding, the consignor generates a distribution list (BOM) according to the e-commerce order (CO), and completes the BOM unloading and packing. If there is no e-commerce order, it can be packaged according to the manufacturer's BOM information, the factory packaged goods BOM content, etc. The data format is agreed by the technical service provider and the shipper. It must contain the valid identification information of the shipper, packaging production line information, BOM, geographic information, etc., in which the shipper can customize random information such as greetings and random gifts. Etc., this information is registered with the image capture information of the packaged package on the blockchain ledger server deployed by the service provider and cannot be changed. This information is also synchronized to the third-party virtual carrier's blockchain server. After registration, both parties can't change it. At the same time, the data is synchronized to the client terminal, and it cannot be changed. (The synchronization in the blockchain is the unreadable information of the encrypted translation. At the same time, it cannot be changed, except that the consignor and the consignee are not readable.

In the process 2, according to the data generated by the BOM production package, the data packet generated as the previous step is combined with the image capture data, combined into a composite data packet, and registered and stored in the blockchain server.

In the process 3, the BOM packing completion signal is used as a trigger to generate the key A, and the data packet generated by the previous process is translated into the encrypted compression code, and the key A is encapsulated and written into the original system. The RAM block specified block in the RFID chip held by the shipper.

Design a relatively solid logistics package, such as PE/PP plastic or wooden box, with an RFID chip and battery, with a tamper-proof device installed in the package closure, to make a buckle lock similar to the normally closed circuit in the alarm circuit Closed device. Once the box is opened, unless the violent destruction of the box causes irreparable damage, the buckle locking device will completely destroy the RAM portion of the RFID, which will cause the chip and the circuit board to be destroyed together. Whether it is the cabinet or the damage of the chip, it is software or physically visible. The abnormal situation can be handled in time, and the responsibility phase can be locked. This fully protects the integrity and process reliability of the package as a technology package.

As shown in FIG. 15, through the docking with the e-commerce system, the information terminal of the end user pointed to by the order number is obtained at the time of delivery, and the technology is bound, and the address of the recipient or the network communication mode is also obtained.

The start of the delivery process is the holder of the package that is packaged by technology at the moment, perhaps a manufacturer or trader, at which point they:

(1) Holding a package that has been bound with an e-commerce user order;

(2) Holds a package that has been packaged by technology, and this package meets the end-user requirements pointed to by the order number.

At this time, if it is the case (1), the consignee's terminal has been bound by technology, then the system sends a one-time decryption Key B to the consignee terminal through the blockchain server, and the Key B can only be used for decryption to be paired. The key A points to a specific technology encapsulation unit that contains the customer's order items.

If it is case (2), the terminal binding activation procedure is executed first, and then the process described in the previous paragraph is executed, so that the specific package encapsulated by the technology can form an end-to-end closed loop with the legal recipient binding terminal. contact.

When the system sends Key B and binds the recipient terminal, the shipper server sends a continuous key N attached to Key A to the first carrier, and the blockchain server issues a delivery statement.

The first carrier reads the count value in the RFID chip wrapped as a technical package unit. If the technical and physical verification is normal, the first carrier holds the Key N and writes the block to the system of the RFID chip pointed by Key N. The own receipt information, after the successful verification of the write, is sent to the consignor blockchain server by the blockchain server deployed to the first carrier (which can be the SAAS server bound to the first carrier) The notification is also the flow 1 in Figure 15.

When the first carrier forwards the package, it issues a delivery statement to the shipper (flow 2 in Figure 15), triggering process 3 (see Figure 15), and the next time Key N+1 is sent to the second by the shipper server. The carrier, the second carrier repeats the operation of the first carrier, and after successful, proceeds to process 4 (see Figure 15), and sends the receipt confirmation to the first carrier, while the current carrier of the first carrier and the second carrier The package retention responsibility status change triggers the process 5, and both parties register the status change with the shipper server.

This mechanism will be implemented backwards until the Xth carrier as the last carrier bears the responsibility of serving the consignee, where the change in the status of the responsibility and the process data are shipped to the various carriers on the entire logistics link. The human server registers and synchronizes the data until the last carrier delivers to the consignee and issues a delivery statement to the consignor server. During the process, Key N-N+X is specified for the number of uses and the validity period. It can be pre-warned before the expiration of the validity period. When the usage count is exhausted, it will be marked abnormally in the following data synchronization.

As shown in Figure 16, after each carrier receives the package, it is assumed that the current carrier is Y, Y first confirms whether the package has physical damage, and if there is physical damage, it directly rejects it; otherwise, it reads the flag judgment technology in the RFID chip. Whether the package is intact or not, and whether it is illegally opened. If all is normal, the receipt is registered. Otherwise, an exception statement is issued to start the exception handling.

The exception handling will notify the previous carrier Y-1 server and send an abnormal status, notifying Y-1 that the package was rejected and notifying the shipper server.

The subsequent warranty is limited to the carrier Y-1, and the consignor issues an agreement with Y-1 for the claim and the notification that the technology package unit has failed. Further, after judging that the technical unit is indeed damaged by physical or technical means (such as chip damage and its minor probability event), the shipper revokes the key B of the technology packaging unit and releases the Key B and the consignee registration. Binding of the terminal.

Further processing can be a customer return or the shipper re-delivery.

As shown in Figure 17, the last carrier X assumes the responsibility of serving the consignee. When the specific dispatcher picks up the goods, the final judgment is that the goods are in good condition, the card is normal with the handheld terminal, and a delivery statement is issued, stating that the goods are delivered. The server of person X is sent to the shipper server. At this time, the shipper server sends the data image registered with the binding technical unit to the legal consignee binding terminal. At this time, the terminal data is complete, and the pre-issued data does not include the image description, such as the package color of the batch.

Prior to this, the shipper server has registered the encapsulated technical unit information encapsulated in the blockchain and has been sent to the legal consignee binding terminal with Key B.

When the consignee receives the goods, confirm that the goods receipt operation is:

(1) The consignee activates the APP or computer program (both through the binding terminal), and uses the NFC or dedicated card reader to read the RFID data on the package of the technology package unit using the held Key B, and with the received data. Data comparison

(2) Further, it is also possible to perform visual comparison by viewing the image image data.

(3) Operate on the APP or client to confirm the receipt.

When the consignee receives the goods, KeyA, B, N-N+X are all abolished, the chip is locked and disabled, and the chip has been destroyed.

Photograph the package by the camera and packaging workbench software that is packaged on the workbench. If the image of the goods can be captured by the camera, it will be verified at the time of receipt. This will greatly increase the difficulty and cost of copying, making the copying work uneconomical and not capable of bulk copying. The intermediate logistics carrier can also retrieve the original image of the package through the legal interface, which is applied in the definition of responsibility and the search of goods.

The packaging platform software system adds a watermark that can indicate the location, environment, time, and identity of the camera when capturing the scene, and retains the “fingerprint” evidence of the image as another means of auxiliary verification packaging in addition to RFID encryption. One.
