Description

Technical Field

[0001] The present invention relates to the field of logistics information technology, and particularly relates to a method for double-encrypting logistics information. Background Art

[0002] Whether it is the product delivery of large enterprises or the incoming goods of raw materials and accessories, logistics is indispensable. Logistics has also played an indelible role in China's economic development and industrial production. On the other hand, with the booming development of online shopping in China, it has further promoted the growth of the demand for the express logistics industry. There are a large number of express deliveries waiting for logistics transportation every day. However, on the other hand, the logistics transportation industry not only requires fast delivery and efficient transportation, but also provides low-cost transportation. The modern logistics industry mainly uses two-dimensional codes, barcodes, and commodity information stickers as express identifiers to play the role of express identification and distribution; information carriers such as two-dimensional codes, barcodes, and information stickers are easily damaged or replaced during transportation, and it is impossible to ensure the consistency of the information between the commodity and the label.

[0003] At the same time, especially for valuable goods, it is not uncommon for the goods to be stolen during the transportation between different stations due to the particularly high value of the goods on the logistics list. Therefore, the confidentiality of logistics information is particularly important. Existing technologies such as Chinese Patent Application No. 201810982580.7, publication date January 18, 2019, disclose an article transportation method and system, which specifically disclose obtaining the logistics information of the transported article and the route information that each staff member at each station can obtain, and encrypting the logistics information and the route information that each staff member can obtain to obtain encrypted logistics information, and then generating a logistics two-dimensional code according to the encrypted logistics information. This method can only encrypt the logistics information and the route information of each station, and it is presented in the form of a two-dimensional code. During the express delivery process, the two-dimensional code is easily damaged by the weather, resulting in subsequent inability to identify. Moreover, this logistics information is only encrypted once at the logistics end. If the personnel at the next station steal the decryption device, it will lead to the problem of low encryption security. Summary of the Invention

[0004] The present invention provides a method for double-encrypting logistics information. Through the method of the present invention, the logistics information can be double-encrypted, which can better protect the data security of the logistics information during transportation between different stations and prevent the logistics information from being stolen or leaked.

[0005] To achieve the above object, the technical solution of the present invention is: a method for double-encrypting logistics information, and the specific steps include:

[0006] (1) The shipping end obtains the logistics information of the input logistics box.

[0007] (2) Upload the logistics information to the cloud password system of the terminal.

[0008] (3) The cloud password system encrypts the logistics information and generates Ciphertext 1 and a sha256 identifier.

[0009] (4) The cloud password system stores Ciphertext 1 and the sha256 identifier, and at the same time sends Ciphertext 1 and the sha256 identifier to the NFC chip on the logistics box, and the NFC chip is encapsulated on the logistics box through a plastic sealing mechanism.

[0010] (5) The NFC chip stores the sha256 identifier, and at the same time encrypts Ciphertext 1 and generates Ciphertext 2 corresponding to the sha256 identifier.

[0011] (6) The NFC chip generates a hardware decryption private key corresponding to Ciphertext 2 and encrypts the hardware decryption private key.

[0012] (7) The NFC chip sends Ciphertext 2 and the encrypted hardware decryption private key to the cloud password system through an NFC reader.

[0013] (8) The receiving end identifies the NFC chip through an NFC reader.

[0014] (9) The NFC chip sends the sha256 identifier to the cloud password system.

[0015] (10) The cloud password system sends the corresponding encrypted hardware decryption private key to the NFC chip for decryption according to the sha256 identifier.

[0016] (11) The NFC chip decrypts the encrypted hardware decryption private key and uses the hardware decryption private key to decrypt Ciphertext 2 to obtain Ciphertext 1, and sends Ciphertext 1 to the cloud password system.

[0017] (12) The receiving end verifies the logistics information in the cloud password system according to Ciphertext 1.

[0018] The above method involves the shipping end encrypting the logistics information to form a sha256 identifier, storing the sha256 identifier in the NFC chip, encrypting the logistics information for the first time, then storing the first ciphertext and the sha256 identifier in the NFC chip on the logistics box, and the NFC chip encrypting the first ciphertext to form the second ciphertext. After encrypting the corresponding private key, it is sent to the cloud password system. Then, the receiving end obtains the sha256 identifier through the NFC reader, retrieves the corresponding encrypted private key from the cloud password system, decrypts the first ciphertext with the decrypted private key, and then sends the first ciphertext to the cloud password system to verify the logistics information. This ensures that the shipping end and the receiving end cannot obtain the logistics information, which is hidden in the NFC chip of the logistics box, and the information transmitted between the cloud password system and the shipping end and the receiving end is ciphertext information. Even the information intercepted on the transmission channel is ciphertext information, thus ensuring data security. At the same time, the shipping end and the receiving end obtain the private key and the encrypted first ciphertext through the cloud password system, so that the receiving end that has not been recognized and authenticated by the NFC reader cannot obtain the logistics information, and the security is higher.

[0019] Further, the step of "encrypting the hardware decryption private key" in step (6) includes: encrypting the hardware decryption private key through a random number generator. The step of "the NFC chip decrypting the hardware decryption private key" in step (11) includes the NFC chip decrypting the encrypted hardware decryption private key through a random number generator to obtain the hardware decryption private key.

[0020] With this setting, by randomly generating the key of the hardware decryption private key, the effect of one-time pad is achieved, so that the decryption of the logistics information of each logistics box is different, thus better protecting the logistics information.

[0021] Further, the cloud password system stores the sha256 identifier, the first ciphertext, the second ciphertext, and the encrypted hardware decryption private key, and the NFC chip stores the sha256 identifier and the second ciphertext.

[0022] Further, step (7) specifically includes the NFC chip uploading the second ciphertext and the encrypted hardware decryption private key encoded in Base64 to the cloud password system through the NFC reader.

[0023] With the above setting, the encrypted hardware decryption private key and the second ciphertext are transmitted in the form of base64 encoding to ensure the reliability of the transmission.

[0024] Further, the logistics information includes key information such as the batch, specification, and weight of the goods to be shipped.

[0025] The above settings enable the key information of the goods to be shipped to be saved, ensuring the safety of the goods to be sent.

[0026] Further, the plastic sealing mechanism includes a wire break detection silicone strip and a thermoplastic film. An NFC chip is provided on the wire break detection silicone strip; the thermoplastic film wraps the logistics box, and the wire break detection silicone strip is provided between the logistics box and the thermoplastic film. The wire break detection silicone strip covers the top end face, bottom end face and side faces of the logistics box.

[0027] The above settings can detect whether there is a wire break in the plastic sealing mechanism by setting the short - wire detection silicone strip of the plastic sealing mechanism on the logistics box.

[0028] Further, the wire break detection silicone strip includes a main silicone strip and a secondary silicone strip. The secondary silicone strip is arranged on the main silicone strip. The center of the main silicone strip is located on one end face of the logistics box, and both ends of the main silicone strip extend to the other end face of the logistics box along the side faces of the logistics box. One end of the secondary silicone strip is connected to the main silicone strip, and the other end of the secondary silicone strip extends outside the main silicone strip to cover at least two corner positions of the logistics box. A detection copper wire is provided inside the main silicone strip and the secondary silicone strip. The detection copper wire is connected to a wire break detection module, the wire break detection module is connected to the NFC chip, and the NFC chip is also communicatively connected to an NFC reader. The NFC chip is arranged at the center of the main silicone strip.

[0029] The above settings enable the logistics box to play an alarm role when it is illegally unsealed by setting the wire break detection silicone strip.

[0030] Further, the main silicone strip includes a silicone layer and a steel sheet. The silicone layer is provided with a silicone upper layer and a silicone lower layer. The detection copper wire is arranged on the steel sheet. The silicone upper layer is provided above the detection copper wire, and the silicone lower layer is arranged below the steel sheet. The detection copper wire is connected to the wire break detection module.

[0031] The above settings, by setting the detection copper wire, when attempting to open the logistics box, the detection copper wire will break when it undergoes secondary deformation, thus playing the role of wire break detection. If the detection copper wire breaks, the wire break detection module will not be able to detect the electrical signal of the detection copper wire, and thus a signal will be sent to the NFC reader through the NFC chip for alarm prompt. The role of the steel sheet is to increase the rigidity of the silicone strip, so that it is firmly fixed on the surface of the logistics box, and at the same time ensure that the copper wire can be bent at an angle close to 90°. After the silicone strip is fixed, the entire logistics box will be wrapped with a TPU thermoplastic film to prevent the silicone strip from falling off. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0043] As Figures 1 to 2 shown, a dual encryption method for logistics information, the specific steps include:

[0044] (1) The shipping end obtains the logistics information of the input logistics box.

[0045] (2) The logistics information is uploaded to the cloud password system of the terminal.

[0046] (3) The cloud password system encrypts the logistics information and generates ciphertext one and sha256 identifier.

[0047] (4) The cloud password system stores the ciphertext one and sha256 identifier, and at the same time sends the ciphertext one and sha256 identifier to the NFC chip on the logistics box, and the NFC chip is encapsulated on the logistics box through the plastic sealing mechanism.

[0048] (5) The NFC chip stores the sha256 identifier, and at the same time encrypts the ciphertext one and generates ciphertext two corresponding to the sha256 identifier.

[0049] (6) The NFC chip generates a hardware decryption private key corresponding to the ciphertext two and encrypts the hardware decryption private key.

[0050] (7) The NFC chip sends the second ciphertext and the encrypted hardware decryption private key to the cloud password system through the NFC reader.

[0051] (8) The receiving end identifies the NFC chip through the NFC reader.

[0052] (9) The NFC chip sends the sha256 identifier to the cloud password system.

[0053] (10) The cloud password system sends the corresponding encrypted hardware decryption private key to the NFC chip for decryption according to the sha256 identifier.

[0054] (11) The NFC chip decrypts the encrypted hardware decryption private key and uses the hardware decryption private key to decrypt the second ciphertext to obtain the first ciphertext, and sends the first ciphertext to the cloud password system.

[0055] (12) The receiving end verifies the logistics information in the cloud password system according to the first ciphertext.

[0056] In the above method, the shipping end encrypts the logistics information to form a sha256 identifier, stores the sha256 identifier in the NFC chip, and encrypts the logistics information for the first time. Then, the first ciphertext and the sha256 identifier are stored in the NFC chip on the logistics box, and the NFC chip encrypts the first ciphertext for the second time to form the second ciphertext, and the corresponding private key is encrypted and sent to the cloud password system. Then, after the receiving end obtains the sha256 identifier through the NFC reader, it obtains the corresponding encrypted private key from the cloud password system, and then decrypts the first ciphertext through the decrypted private key, and then sends the first ciphertext to the cloud password system to verify the logistics information. Thus, the shipping end and the receiving end cannot obtain the logistics information, and the logistics information is hidden in the NFC chip of the logistics box. Moreover, the information transmitted between the cloud password system and the shipping end and the receiving end is ciphertext information. Even the information intercepted on the transmission channel is ciphertext information, thus ensuring the security of the data. At the same time, the shipping end and the receiving end obtain the private key and the encrypted first ciphertext through the cloud password system, so that the receiving end without being recognized by the NFC reader cannot obtain the logistics information, and the security is higher. In this embodiment, the terminal is a terminal such as a PC terminal that can process information, which is a specific existing technology and will not be elaborated here.

[0057] The step of "encrypting the hardware decryption private key" in step (6) includes: encrypting the hardware decryption private key through a random number generator. The step of "the NFC chip decrypts the hardware decryption private key" in step (11) includes that the NFC chip decrypts the encrypted hardware decryption private key through a random number generator to obtain the hardware decryption private key.

[0058] With this setting, by using the key of the randomly generated hardware decryption private key, the effect of one-time pad is achieved, so that the decryption of the logistics information of each logistics box is different, thus better protecting the logistics information.

[0059] The cloud password system stores the sha256 identifier, ciphertext one, ciphertext two, and the encrypted hardware decryption private key. The NFC chip stores the sha256 identifier and ciphertext two.

[0060] Step (7) specifically includes that the NFC chip uploads the ciphertext two and the encrypted hardware decryption private key to the cloud password system in Base64 encoding through the NFC reader.

[0061] With the above setting, by transmitting the encrypted hardware decryption private key and ciphertext two in the way of Base64 encoding, the reliability of the transmission is ensured.

[0062] In this embodiment, the ciphertext one and ciphertext two are encrypted by using the elliptic curve encryption method.

[0063] The logistics information includes key information such as the batch, specification, and weight of the goods to be shipped.

[0064] With the above setting, the key information of the goods to be shipped can be saved, ensuring the security of the goods to be sent.

[0065] As Figures 3 - 10 shown, the plastic sealing mechanism includes a wire break detection silicone strip and a heat shrinkable film (not shown in the figure). The NFC chip 7 is connected to the wire break detection silicone strip; the heat shrinkable film wraps the logistics box, and a wire break detection silicone strip is provided between the logistics box and the heat shrinkable film. The wire break detection silicone strip covers the top surface, bottom surface, and side surface of the logistics box.

[0066] With the above setting, by setting the short wire detection silicone strip of the plastic sealing mechanism on the logistics box, it can be detected whether there is a wire break in the plastic sealing mechanism.

[0067] As Figure 3 shown, the wire break detection silicone strip 1 includes a main silicone strip 11 and a sub-silicone strip 12. The sub-silicone strip 12 is arranged on the main silicone strip 11. The center of the main silicone strip 11 is located at one end face of the logistics box 01, and both ends of the main silicone strip 11 extend to the side surface of the logistics box 01 to the other end face. One end of the sub-silicone strip 12 is connected to the main silicone strip 11, and the other end of the sub-silicone strip 12 extends outward from the main silicone strip 11 to cover the end face and side surface of the logistics box 01. A detection copper wire 112 is arranged in the main silicone strip and the sub-silicone strip. The detection copper wire is connected to the wire break detection module. The wire break detection module is arranged at the center of the main silicone strip 11, and the wire break detection module is communicatively connected to the NFC reader. In this embodiment, the NFC reader is a signal conversion carrier, which is a specific prior art and will not be elaborated here.

[0068] With the above settings, by setting the wire break detection silicone strip, the logistics box can play an alarm role when it is illegally unsealed.

[0069] As Figure 4 shown, the main rubber strip 11 includes a silicone layer 111 and a steel sheet 113. The silicone layer 111 is provided with a silicone upper layer 1111 and a silicone lower layer 1112. The detection copper wire 112 is arranged on the steel sheet 113. The silicone upper layer 1111 is arranged above the detection copper wire 112, and the silicone lower layer 1112 is arranged below the steel sheet 113. With the above settings, by setting the detection copper wire, when the wire break detection module detects an abnormal wire break of the detection copper wire, the wire break detection module sends a signal to the NFC reader, thereby prompting the staff at the site that the logistics box has traces of being unsealed, so that the staff can check whether the logistics box has been stolen, lost or damaged.

[0070] As Figures 3 - 10 shown, the wire break detection module 2 includes a diode LED1, a diode LED2, a diode LED3, a diode LED4, a resistor R7, a resistor R8, a resistor R9, and a resistor R10. The positive electrode of the diode LED1 is connected to the first pin of the sending chip through a detection copper wire, and the negative electrode of the diode LED1 is grounded through one end of the resistor R7. The positive electrode of the diode LED2 is connected to the second pin of the sending chip through a detection copper wire, and the negative electrode of the diode LED2 is grounded through one end of the resistor R8. The positive electrode of the diode LED3 is connected to the fourteenth pin of the sending chip through a detection copper wire, and the negative electrode of the diode LED3 is grounded through one end of the resistor R10. The positive electrode of the diode LED4 is connected to the thirteenth pin of the sending chip through a detection copper wire, and the negative electrode of the diode LED4 is grounded through one end of the resistor R11.

[0071] The NFC chip includes a main control chip, a signal emission module, and a power supply circuit. The power supply circuit is connected to the main control chip U3, and the main control chip U3 is communicatively connected to the NFC reader; the power supply circuit includes a wireless power supply circuit, and the wireless power supply circuit includes a wireless power supply coil, a transfer interface J1, a capacitor C9, a capacitor C7, and a capacitor C8. The positive electrode of the wireless power supply coil is connected to the first pin of the transfer interface J1, and the negative electrode of the wireless power supply coil is connected to the second pin of the transfer interface J1. The second pin of the transfer interface J1 is grounded; a capacitor C9, a capacitor C7, and a capacitor C8 are connected between the positive electrode and the negative electrode of the wireless power supply coil; one end of the detection copper wire is connected to the transfer interface J1, and the other end of the detection copper wire is connected to the main control chip U6. The wireless power supply coil is also connected to the signal emission module and charges the chip emission module. In this embodiment, the model of the main control chip U3 is STM32F103C8T6.

[0072] With the above settings, during power supply, the wireless power supply coil sends a power supply signal to the main control chip U3 to achieve power supply. At the same time, the disconnection detection module is connected to the signal transmission module through the detection copper wire. When the detection copper wire is disconnected, the disconnection detection module disconnects, so that the corresponding pin of the signal transmission module is set high, and thus the power supply voltage of the wireless power supply coil cannot be detected. Then, an alarm signal is sent to the NFC reader through the main control chip U3 for alarm indication.

[0073] As Figure 6 shown, the signal transmission module includes a chip U6. The 1st, 2nd, 13th, and 14th pins of the chip U6 are connected to the detection copper wire; the 3rd - 6th, 9th - 12th, 15th - 18th, and 21st - 24th pins of the chip U6 are left unconnected; the 7th pin of the chip U6 is connected to the power supply circuit, the 8th and 25th pins of the main control chip U6 are grounded, and a capacitor C16 is provided between the 7th and 8th pins of the chip U6; the 19th pin of the main control chip U6 is connected to the 2nd pin of the signal transmitter U5, the 20th pin of the chip U6 is connected to the 1st pin of the signal transmitter U5, and capacitors C17, C18, and C19 are provided between the 19th and 20th pins of the chip U6; the signal transmitter U5 is communicatively connected to the NFC reader.

[0074] In this embodiment, the NFC reader is a signal conversion carrier, which can be a mobile phone or a tablet computer, which is a specific prior art and will not be elaborated here.

[0075] With the above settings, when the chip U6 detects an abnormal disconnection of the detection copper wire, the chip U6 sends a signal to the signal transmitter U5 through the 19th and 20th pins, and then the signal transmitter U5 sends a disconnection abnormal signal to the reader, thus reminding the staff of the risk of theft, loss, or damage of the logistics box.

[0076] In this embodiment, as Figure 10 shown, the model of the main control chip U3 is STM32F103C8T6. The main control chip U3 is used to encrypt and decrypt logistics information, and at the same time send the encrypted and decrypted data to the chip U6 of the signal transmission module and then transmit it to the NFC reader.

[0077] As Figure 7 shown, the power supply circuit further includes a USB power supply circuit 5. The USB power supply circuit 5 includes a USB interface, a connector U4, and a capacitor C5. The 1st pin of the USB interface is connected to the 3rd pin of the connector U4, the 5th and 6th pins of the USB interface are grounded, and the 2nd - 4th pins of the USB interface are left unconnected; the 1st pin of the connector U4 is grounded, the 2nd pin of the connector U4 is connected to the 7th pin of the main control chip U6, and the 3rd pin of the connector U4 is also grounded through the capacitor C5.

[0078] With the above settings, the chip U6 can be powered through the settings of the USB interface. The structure is simple and effective. When powering, the USB interface is connected to an external charging device, and then the charging voltage emitted by the charging device passes through the second pin of the connector U4 to the seventh pin of the main control chip U6, thus realizing power supply.

[0079] With the above settings, by setting the detection copper wire, when attempting to open the logistics box, the detection copper wire will break when it undergoes secondary deformation, thus playing the role of breakage detection. If the detection copper wire breaks, the main control chip U6 will not be able to detect the electrical signal of the detection copper wire, and thus a signal will be sent to the NFC reader through the signal transmitter for alarm prompt. The role of the steel sheet is to increase the rigidity of the silicone tape, making it firmly fixed on the surface of the logistics box, and at the same time ensuring that the copper wire can be bent at nearly 90°. After the silicone tape is fixed, the entire logistics box will be wrapped with a TPU thermoplastic film to prevent the silicone tape from falling off. In this embodiment, the upper silicone layer and the lower silicone layer are each 1 mm thick, having a certain elasticity and ductility, and can protect the express delivery to a certain extent. By setting the detection copper wire, when the breakage detection module detects an abnormal breakage of the detection copper wire, the breakage detection module sends a signal to the reader, thus prompting the staff at the station that the logistics box has signs of being unsealed, so that the staff can check whether the logistics box has been stolen, lost or damaged.
