Description

Technical Field

[0002] With the development of science and technology, smart electronic devices have been widely used in the fields of medical care, communications, industrial automation and consumer electronics. Regardless of the industry, reliable, secure and efficient data transmission is crucial.

[0003] In the medical industry, the data security (also known as cybersecurity in regulations) of electronic components within electronic medical devices is becoming increasingly important. Traditional medical control devices lack a dedicated engineering service (data transmission) interface on the device housing for embedded hardware (such as printed circuit boards), as is the case with USB and HDMI interfaces. While this design prevents data stored on the PCB from being uploaded or downloaded arbitrarily, enhancing the cybersecurity of electronic components, it also creates certain inconveniences for maintenance and repair by engineers. Whenever an embedded program on the PCB needs to be updated or a device experiences an electronic circuit malfunction, engineers often need to completely open the device's outer casing to connect to the data interface on the PCB for program overwriting and communication diagnostics. Furthermore, if an engineering service interface is required on the housing, encryption software must be designed and installed to ensure communication security, significantly increasing R&D costs and complexity.

[0004] Therefore, in order to improve the convenience of maintenance and repair, and to protect the data security of the host's internal system, it is particularly important to design a data transmission solution that can both ensure data security and facilitate maintenance. Utility Model Content

In the description of the present invention, it should be noted that the term "or" is generally used in the sense of including "and / or" unless the content clearly indicates otherwise.

[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or a magnetic connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be a communication between the two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances. In addition, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0032] Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Example 1

[0034] The embodiment of the utility model provides a variable encryption data transmission harness, the structure of which includes several data transmission wires, such as Figure 1Each data transmission wire includes a wire body 10 and transmission connectors 20 at both ends. The transmission connectors 20 at both ends are configured as type-I terminals 21 and / or type-II terminals 22. The type-I terminals 21 and type-II terminals 22 can be detachably connected. The two ends of the variable encryption data transmission harness are configured as a first connection part and a second connection part. The first connection part and the second connection part both include transmission connectors 20 of multiple data transmission wires. The multiple transmission connectors 20 are arranged in a preset geometric shape, and the type-I terminals 21 and type-II terminals 22 are arranged in a preset arrangement order.

[0035] In a preferred embodiment, the wire body 10 is responsible for transmitting electrical signals or data signals between different devices and is a channel for data transmission. It is made of a highly conductive metal material and covered with an insulating layer to prevent short circuits and electromagnetic interference.

[0036] In a preferred embodiment, the transmission connectors 20 at both ends of the wire body 10 can be the same or different, so the transmission connectors 20 at both ends can be configured as type I terminals 21, or both can be configured as type II terminals 22, or one end can be a type I terminal 21 and the other end can be a type II terminal 22.

[0037] In a preferred embodiment, the type 1 terminal 21 is configured as a male connector, and the type 2 terminal 22 is configured as a female connector. Figure 1 As shown, the male and female connectors have complementary shapes and mating structures, respectively, so that the male connector can be inserted into the female connector and form electrical contact. The structure of the male and female connectors ensures the stability and conductivity of the connection, while facilitating plugging and unplugging operations, and achieving detachable engagement with the female connector. Those skilled in the art will understand that the male and female structures of the type-1 terminal 21 and the type-2 terminal 22 are also interchangeable. When the type-1 terminal 21 is configured as a female connector, the type-2 terminal 22 is correspondingly configured as a male connector.

[0038] Specifically, the type 1 terminal 21 is provided with multiple metal contact pins or contacts, and a protective shell made of plastic or other insulating materials is provided on the outside. The type 2 terminal 22 is provided with multiple metal contact holes or slots, and a protective shell is also provided on the outside. The structure of the metal contact pins and the metal contact holes ensures good conductivity between the two, reduces contact resistance, and ensures efficient signal transmission. The protective shells of the two can be further provided with a locking structure, such as a thread or a buckle, to ensure the mechanical stability of the connection between the type 1 terminal 21 and the type 2 terminal 22 to prevent loosening or falling off.

[0039] In a preferred embodiment, a standard 2.54 DuPont wire can be used as the conductor body 10, with a highly conductive metal core inside and an insulating layer outside. The Type I terminal 21 is a male connector, also known as a pin, at one end of the standard DuPont wire, and the Type II terminal 22 is a female connector, also known as a jack, at the other end of the standard DuPont wire. Those skilled in the art will appreciate that 2.54 DuPont wire is a standard cable widely used for electronic connections, with its pins having a 2.54mm pitch. This specification makes it suitable for most electronic component and circuit board interfaces, particularly for various embedded systems, ensuring compatibility with other standard 2.54 DuPont interfaces.

[0040] In a preferred embodiment, the conductor body 10 and the transmission connectors 20 at both ends can be fixedly connected by crimping or threading.

[0041] Preferably, the transmission connectors 20 at both ends of each data transmission wire in the variable encryption data transmission harness can be used to be inserted into the interface of the embedded device, and can also be used to axially continue to connect to another data transmission wire; when the two ends of each data transmission wire are used to connect to the embedded device and the external device respectively, the transmission connectors 20 of each data transmission wire are used to form the first connection part and / or the second connection part, or the first connection part and / or the second connection part are composed of the transmission connectors 20 of some data transmission wires and empty connectors; when the data transmission wire is used to axially continue to connect to another data transmission wire, in the variable encryption data transmission harness, the transmission connectors 20 of at least some of the data transmission wires are used to axially connect other data transmission wires, and the axially adjacent data transmission wires are connected through a combination of the first terminal and the second terminal, and the transmission connectors 20 at both ends of multiple axially connected data transmission wires are used to form the first connection part or the second connection part.

[0042] When the transmission connector 20 of the data transmission wire continues to be connected to other data transmission wires, on the one hand, the extension length of the variable encrypted data transmission harness can be extended, and on the other hand, the male and female properties of the transmission connector 20 that is finally connected to the interface of the embedded device can be changed, thereby adjusting the ratio of the number of male connectors and female connectors in the first connection part and / or the second connection part. For example, when one end of a transmission wire is a male connector, if you want to change it to a female connector, you can directly connect a data transmission wire with female connectors at both ends to achieve the change of the male and female properties of the transmission connector 20 of the transmission wire.

[0043] Those skilled in the art should understand that when only the transmission connectors 20 of some of the data transmission wires in the variable encryption data transmission harness are used to continue connecting other data transmission wires, the total length of the variable encryption data transmission harness remains unchanged, and the length of the variable encryption data transmission harness depends on the length of the shortest data transmission wire in the harness.

[0044] Preferably, the first connection portion is used to connect to an interface of an embedded device, and the second connection portion is used to connect to an external device (such as a PC). It should be understood that the connection objects of the first connection portion and the second connection portion can also be interchangeable.

[0045] In a preferred embodiment, the first connection portion and the second connection portion of the variable encryption data transmission harness have the same preset geometric shape, which includes a matrix arrangement, a linear arrangement, a ring arrangement, a radial arrangement or other irregular arrangement.

[0046] Specifically, since each transmission joint 20 of the second connection part corresponds one-to-one to the transmission joint 20 at the same position of the first connection part, the two have the same preset geometric shape.

[0047] Preferably, when the preset geometric shape is a matrix arrangement, the transmission joints 20 located at the first connection part / the second connection part are arranged in rows and columns to form a matrix, and the matrix can be 3x3, 4x4, etc.; when the preset geometric shape is a linear arrangement, the transmission joints 20 located at the first connection part / the second connection part are arranged in a straight line; when the preset geometric shape is a ring arrangement, the transmission joints 20 located at the first connection part / the second connection part are arranged in a circular ring shape to form a closed ring; when the preset geometric shape is a radial arrangement, the transmission joints 20 located at the first connection part / the second connection part are arranged radially from the center to the outside; when the preset geometric shape is an irregular arrangement, the transmission joints 20 located at the first connection part / the second connection part are arranged in an irregular shape. Possible forms of irregular shapes are not listed here one by one, and those skilled in the art can customize them according to specific needs.

[0048] In a preferred embodiment, when the interfaces of the embedded device connected to the first connecting portion are arranged in a matrix, but the matrix contains one or more empty interfaces, at this time, since the empty interfaces may not be configured with matching transmission connectors 20, the first connecting portion and the second connecting portion in this case are both arranged in an irregular shape.

[0049] In another preferred embodiment, when the interface of the embedded device connected to the first connecting part is arranged in a matrix, but the matrix contains one or more empty interfaces, at this time, one or more matching transmission connectors 20 can also be configured in the first connecting part. Although the transmission connector 20 does not transmit the corresponding electrical signal or data signal, it can make the first connecting part and the second connecting part arranged in a matrix, which is convenient for the arrangement of several data transmission wires in the variable encryption data transmission harness.

[0050] In a preferred embodiment, the first connection part and the second connection part of the variable encrypted data transmission harness have the same or different preset arrangement orders. The preset arrangement order refers to the arrangement order of the type I terminal 21 and the type II terminal 22. Preferably, the preset arrangement order includes alternating arrangement or specific coding rule arrangement.

[0051] As described above, since the transmission connectors 20 at both ends of the data transmission wire can be the same or different, the first connection portion and the second connection portion can be arranged in the same, different, or partially the same and partially different order; since the transmission connector 20 of the data transmission wire can continue to be connected to other data transmission wires, the arrangement order of the first connection portion and the second connection portion can be changed by adjusting the male and female properties of the transmission connectors 20 of other data transmission wires to which one or some data transmission wires are axially connected.

[0052] In a preferred embodiment, when the preset arrangement order is an alternating order, the type-1 terminals 21 and the type-2 terminals 22 are arranged in an alternating manner. Specifically, it can be configured as several type-1 terminals 21 and one or several type-2 terminals 22 being arranged alternately, or several type-2 terminals 22 and one or several type-2 terminals 22 being arranged alternately.

[0053] To improve security, it is more preferred to arrange the type 1 terminal 21 and the type 2 terminal 22 in a specific coding order, that is, the type 1 terminal 21 and the type 2 terminal 22 are arranged according to a certain coding rule, and the coding rule can be designed based on a specific algorithm to ensure the reliability of encryption.

[0054] Taking the first connection part as an example, which is configured as a 3x3 matrix arrangement, in this matrix, the arrangement order of the first row can be type 1 terminal 21, type 2 terminal 22, type 2 terminal 22, the arrangement order of the second row can be type 2 terminal 22, type 2 terminal 22, type 1 terminal 21, and the arrangement order of the third row can be type 1 terminal 21, type 1 terminal 21, type 2 terminal 22.

[0055] In the above embodiment, the data interface is protected and encrypted by physically changing the number ratio and arrangement order of the male and female connectors in the first connection part / second connection part, and the interface order and quantity can be modified at any time to achieve physical level encryption and enhance the security of the data interface.

[0056] In a preferred embodiment, a digital identification may be further provided on each transmission connector 20 to record each configuration.

[0057] like Figure 2Preferably, a detachable connection structure is further provided on the side of each transmission joint 20, and the detachable connection structure is used to detachably connect with the transmission joint 20 adjacent to the side, thereby realizing mechanical interlocking and firm connection between the transmission joints 20.

[0058] In a preferred embodiment, the detachable connection structure is configured as a complementary guide groove 23 or a slider 24. The guide groove 23 is provided on the side of one transmission joint 20, and the slider 24 is provided on the side of an adjacent transmission joint 20. The guide groove 23 can slide with the slider 24 to achieve a tight connection between adjacent transmission joints 20.

[0059] Specifically, the guide groove 23 is a groove provided on the side of a transmission joint 20, has a certain depth and width, and extends along the axial direction of the transmission joint 20 so that the slider 24 can be smoothly inserted and slid. The guide groove 23 is preferably made of the same material as the main body of the transmission joint 20; the slider 24 is a protrusion provided on the side of the adjacent transmission joint 20, designed to be shaped to match the guide groove 23, and its material is preferably the same as the main body of the transmission joint 20.

[0060] In a preferred embodiment, the detachable connection structure includes a magnet 25 disposed on the side of one transmission connector 20 and another magnet 25 disposed on the side of an adjacent transmission connector 20. The two magnets 25 can attract each other and magnetically connect to achieve a tight connection between the adjacent transmission connectors 20. At this time, the electromagnetic compatibility (EMC) of the data transmission wire can also be improved, thereby enhancing the anti-interference capability.

[0061] Preferably, magnets 25 are provided on both axial end faces and side faces of the transmission connector 20 , and the magnets 25 on opposite faces have different polarities to achieve connection with the transmission connector 20 adjacent in the axial direction or on the side faces.

[0062] Specifically, a magnet N is provided on the side of a certain transmission connector 20, and a magnet S is provided on the adjacent surface of an adjacent transmission connector 20. The magnet N and the magnet S have relative polarities. When the two transmission connectors 20 are close to each other, the magnet N and the magnet S will attract each other, thereby achieving a stable connection.

[0063] By setting up a detachable connection structure, not only can a tight connection between the transmission connectors 20 be achieved to prevent loosening and separation, but the installation and disassembly process is also simple and convenient without the need for additional tools. At the same time, since the transmission connectors 20 can be combined and disassembled as needed, the flexibility and scalability of the configuration in the variable encryption data transmission harness of the data transmission wires are improved.

[0064] Compared with the existing technology, the technical solution in this embodiment is based on the preset geometric shape / preset arrangement order of the data transmission harness and interface, and realizes encryption at the hardware level. By adjusting the geometric arrangement of the transmission connector 20 and the arrangement order of the male and female connectors, the encryption rules can be flexibly changed. This complex physical arrangement increases the difficulty of cracking, making the encryption method more complex and unpredictable, further improving the security of data transmission.

[0065] Example 2

[0066] An embodiment of the present utility model provides a variable encryption docking system, including the variable encryption data transmission harness in the above embodiment 1. The technical features recorded in the above embodiment 1 are naturally inherited in this embodiment and will not be repeated.

[0067] Preferably, the variable encryption docking system includes a variable encryption data transmission harness and a variable encryption data transmission interface 30. The variable encryption data transmission interface 30 includes an interface on the embedded device side and an interface on the external device side. The two ends of the variable encryption data transmission harness are respectively matched and connected with the interface on the embedded device side and the connector on the external device side to perform data transmission.

[0068] In a preferred embodiment, taking the variable encrypted data transmission interface 30 at the embedded device end as an example, the first connection part of the variable encrypted data transmission harness is matched and connected with the interface at the end, and the variable encrypted data transmission interface 30 includes several first sub-interfaces and second sub-interfaces, and the first sub-interfaces and the second sub-interfaces are arranged in a preset geometric shape, and the first sub-interfaces and the second sub-interfaces are arranged in a preset arrangement order.

[0069] Preferably, various types of pins are provided in the mainboard of the embedded device, and different pins are respectively connected to a first sub-interface or a second sub-interface. The first sub-interface is configured as a female interface and can be connected to a type I terminal 21 in the first connection part. The second sub-interface is configured as a male interface and can be connected to a type II terminal 22 in the first connection part.

[0070] Preferably, the first sub-interface and the second sub-interface are arranged in a specific geometric shape, such as a matrix arrangement, a linear arrangement, a circular arrangement, a radial arrangement, or other irregular arrangement. This geometric shape is symmetrical with the geometric shape of the transmission connector 20 in the first connection portion, and each first sub-interface corresponds to a type-one terminal 21, and each second sub-interface corresponds to a type-two terminal 22. Preferably, the first sub-interface and the second sub-interface are arranged in a preset arrangement order. To ensure that the first connection portion corresponds to it, the arrangement order of the type-one terminals 21 and the type-two terminals 22 in the first connection portion is symmetrical with the arrangement order of the first sub-interface and the second sub-interface, so as to ensure that each type-one terminal 21 corresponds to a first sub-interface, and each type-two terminal 22 corresponds to a second sub-interface.

[0071] In another preferred embodiment, still taking the interface of the embedded device end as an example, the first connection part of the variable encrypted data transmission harness is matched and connected with the interface of the end, and the variable encrypted data transmission interface 30 includes several first sub-interfaces, second sub-interfaces and third sub-interfaces, which are arranged in a preset geometric shape and arranged in a preset arrangement order.

[0072] Preferably, the mainboard of the embedded device is provided with various types of pins with data transmission functions and empty pins, and different pins with data transmission functions are respectively connected to a first sub-interface or a second sub-interface, the first sub-interface is configured as a female interface, which can be connected to a type I terminal 21 in the first connection part, the second sub-interface is configured as a male interface, which can be connected to a type II terminal 22 in the first connection part, and the empty pin is connected to the third sub-interface, that is, the third sub-interface is configured as an empty interface, and the empty interface corresponds to the empty connector in the first connection part and / or the second connection part.

[0073] In a preferred embodiment, the first sub-interface, the second sub-interface and the third sub-interface are arranged in a preset geometric shape. When the variable encrypted data transmission harness is provided with a corresponding transmission connector 20 at the position of the first sub-interface, the transmission connector 20 does not transmit data and is only used for shape matching. At this time, the geometric shape arrangement of the overall transmission connector 20 in the first connection part is symmetrical with the interface of the embedded device; when the variable encrypted data transmission harness is not provided with a corresponding transmission connector 20 at the position of the first sub-interface, the geometric shape arrangement of the overall transmission connector 20 in the first connection part is asymmetrical with the interface of the embedded device.

[0074] In a preferred embodiment, the first sub-interface, the second sub-interface and the third sub-interface are arranged in a preset order, and the arrangement order of the type I terminal 21 and the type II terminal 22 in the first connecting portion is symmetrical to the arrangement order of the first sub-interface and the second sub-interface.

[0075] In a preferred embodiment, an embedded device is configured with four mainboards as an example. Each mainboard is provided with three pins: SDIO, GND, and SWCLK, and one unused pin. Except for the four unused pins, the other pins are connected to a first sub-interface or a second sub-interface. Each unused pin is connected to a third sub-interface. All pins are connected to a 4×4 matrix interface. After the positions of the four third sub-interfaces are determined, the remaining interfaces can be arranged arbitrarily. In this case, there can be 7,464,960 randomly arranged interface combinations, as follows:

[0076] like Figure 3 , define the third sub-interface as A, the second sub-interface as B, the first sub-interface as C, and define the 4×4 matrix as 16 grids. The first step is to select 4 grids to fill A, which can be calculated by the combination number, that is, the number of ways to select 4 from 16 different elements, recorded as C(16,4), which is calculated to be 1820; the second step is for the remaining 12 grids, each grid can be independently filled with B or C, which means that for each grid, there are two choices. Therefore, if there are no restrictions, these 12 grids can be filled with 2 12 different ways to be filled (because each position has two possible numbers), there are 2 12 The calculated value is 4096. However, since there is no limit on the number of B and C, this means that as long as all grids are not identical, any allocation is allowed. Based on the above analysis, we can directly use 2 12 The number of possibilities for this part is reasonable because it already includes all possible combinations of B and C.

[0077] In theory, the first and second steps should be multiplicative, as they are two independent selection processes. However, it is important to note that the first step has already determined the specific four boxes to be filled with A, and the second step operates on this basis. Therefore, the total number of permutations and combinations is 1820 × 4096 = 7464960. In summary, there are a total of 7464960 different possibilities.

[0078] Compared with the existing technology, this embodiment realizes encryption at the hardware level by directly embedding encryption logic in the physical connection, eliminating the need to rely on software algorithms or external encryption devices, avoiding possible vulnerabilities and attack risks in software encryption, making the system more secure and reliable, and not affected by software updates or vulnerabilities. It also reduces the need for complex encryption software and protocols, simplifies the system architecture, thereby improving the efficiency and security of encryption during data transmission, and reducing maintenance difficulty.
