[0002] Existing technologies for preventing unauthorized network connections primarily employ software and hardware encryption, which are technically challenging, costly, and ineffective. In certain specialized network systems, such as my country's dedicated medical insurance network, the problem of unauthorized connections from authorized medical insurance network terminals persists, and this issue remains unresolved. Summary of the Invention

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a secure network encryption and decryption system for preventing unauthorized connections and theft, comprising a missing-line encryption structure and a decryption structure. The missing-line encryption structure includes a first circuit board and a first network cable interface. Both the first circuit board and the first network cable interface are provided with 8 wire sequence interfaces. Some of the 8 wire sequence interfaces transmit data, while the rest do not. Some or all of the non-data-transmitting wire sequence interfaces on the first circuit board are missing. Data-transmitting wire sequence interfaces are connected to the remaining non-data-transmitting wire sequence interfaces, or data-transmitting wire sequence interfaces are interconnected to form an encrypted wire sequence. The decryption structure includes a network cable decryption structure, a corresponding decryption structure, and a hybrid decryption structure. The network cable decryption structure includes a first decryption network cable and a standard network cable interface. The first decryption network cable is configured according to the missing-line encryption structure. The encrypted wiring sequence is fabricated and connected to the corresponding standard wiring sequence. The encrypted wiring sequence end is connected to the first network cable interface, and the standard wiring sequence end is connected to the standard network cable interface. The standard network cable interface uses the standard wiring sequence. The corresponding decryption structure includes a standard network cable, a second network cable interface, and a second circuit board. The standard network cable uses the standard wiring sequence, with one end connected to the first network cable interface and the other end connected to the second network cable interface. The wiring method of the second network cable interface and the second circuit board is the same as that of the first circuit board and the first network cable interface. The hybrid decryption structure includes a second decryption network cable, a third network cable interface, and a third circuit board. The second decryption network cable uses a jumper wire arrangement inside, with one end connected to the first network cable interface and the other end connected to the third network cable interface. The third network cable interface is connected to the standard wiring sequence of the third circuit board according to the jumper wire arrangement of the second decryption network cable.
[0005] Furthermore, data transmission is possible through the first circuit board and the first network cable interface on lines 1, 2, 3, and 6, while data transmission is not possible through lines 4, 5, 7, and 8.
[0006] Furthermore, the missing-line encryption structure is located in the upstream network device, and the decryption structure is located in the downstream network device.
[0007] Furthermore, the housings of the upper and lower network devices are secured with tamper-proof screws.
[0008] Furthermore, the housings of the upper and lower network devices are fixed together using hot melt adhesive.
[0009] Furthermore, the first circuit board and the first network cable interface are connected by soldering.
[0010] Compared with the prior art, the beneficial effects of the present invention are: the present invention solves the problems that the existing network anti-unauthorized connection and theft technologies are difficult, costly and ineffective.
[0011] This invention solves a long-standing but unresolved technical problem. Instead of using commonly employed software or hardware encryption technologies, it employs the simplest method of changing the wiring, overcoming existing technical biases. This invention is simple in structure, easy to implement, and effectively solves the problem of unauthorized connections to existing medical insurance dedicated networks. Its application has yielded excellent results, virtually eliminating unauthorized connections.
[0012] This invention breaks away from traditional standard networking systems by modifying network equipment and creating a self-developed networking system based on the principle of physical encryption. It can be used not only for leased lines but also in all network domains, including the Internet, private networks, virtual private networks, and intranets, and can be widely applied to any network node requiring protection against unauthorized connections. The principle is to first change the direct connection sequence between the circuit boards and Ethernet ports on network devices, system hosts, storage, and computer terminals, thus disrupting the connection sequence and achieving physical encryption.
[0013] This invention requires only simple modifications to network equipment, causing no damage, boasting a high success rate, and offering strong operability. For large-scale applications, customization can be negotiated with manufacturers for rapid and effective deployment. The network system's encryption principle is simple, practical, and widely applicable. Besides general internet, leased lines, and virtual private networks, it is also suitable for enterprise networks requiring protection against unauthorized connections. Beyond civilian applications, the network system and encryption principles can also be applied to lines or network equipment in military, public security, national security, banking, and financial sectors, effectively preventing unauthorized physical access and providing effective protection for national cybersecurity.

Detailed Implementation
[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
[0022] See Figures 1-6This embodiment describes a secure network encryption / decryption system for preventing unauthorized connections and theft. It includes a missing-wire encryption structure and a decryption structure. The missing-wire encryption structure includes a first circuit board 1 and a first network cable interface 2. Both the first circuit board 1 and the first network cable interface 2 have eight wire sequence interfaces. Some of these interfaces transmit data, while the rest do not. Some or all of the non-data-transmitting wire sequence interfaces on the first circuit board 1 are missing. Data-transmitting wire sequence interfaces are connected to the remaining non-data-transmitting wire sequence interfaces, or data-transmitting wire sequence interfaces are interconnected, forming an encrypted wire sequence. The decryption structure includes a network cable decryption structure, a corresponding decryption structure, and a hybrid decryption structure. The network cable decryption structure includes a first decryption network cable 4 and a standard network cable interface 6. The first decryption network cable 4 has a connector made according to the encryption wire sequence of the missing-wire encryption structure and corresponds to the standard wire sequence. The encryption wire sequence end is connected to the first network cable interface 2, and the standard wire sequence end is connected to the standard network cable interface 6, wherein the standard network cable interface 6 is a standard wire sequence. The corresponding decryption structure includes a standard network cable 7, a second network cable interface 8, and a second circuit board 9. The standard network cable 7 is a standard wire sequence, with one end connected to the first network cable interface 2 and the other end connected to the second network cable interface 8. The wiring method of the second network cable interface 8 and the second circuit board 9 is the same as the wiring method of the first circuit board 1 and the first network cable interface 2. The hybrid decryption structure includes a second decryption network cable 10, a third network cable interface 11, and a third circuit board 12. The second decryption network cable 10 adopts a jumper wire sequence arrangement inside, with one end connected to the first network cable interface 2 and the other end connected to the third network cable interface 11. The third network cable interface 11 is connected to the standard wire sequence of the third circuit board 12 according to the jumper wire sequence of the second decryption network cable 10.
[0023] In this embodiment, data transmission occurs at the first circuit board 1 and the first network cable interface 2 via pins 1, 2, 3, and 6, while data transmission does not occur at pins 4, 5, 7, and 8. Figure 2 As shown, when the first circuit board 1 and the first network cable interface 2 are connected, some or all of the wiring 4, 5, 7, and 8 in the wiring sequence of the first circuit board 1, which do not transmit data, are missing. The wiring 1, 2, 3, and 6, which transmit data, are connected to the remaining wiring without data transmission, or the wiring 1, 2, 3, and 6 are connected to each other. The missing wire encryption structure is set in the upper network device 3, and the decryption structure is set in the lower network device 5.
[0024] Network cable decryption structure as follows Figure 3As shown, the upper-end network device 3 uses an encrypted Ethernet port. Connectors are made according to the encrypted wiring sequence using network cables corresponding to the network interfaces of the upper-end network device. The lower-end network device 5 uses a standard wiring sequence and connects to network devices or network cards with standard network cable ports. The characteristic of this network cable decryption structure is that it relies on the network cable to achieve decryption. If the network cable is lost and a standard network cable is used to connect the upper and lower-end devices, the network will not be able to connect. This encryption has 1680 encryption combinations.
[0025] The corresponding decryption structure is as follows Figure 4 As shown, the upper-end network device 3 and the lower-end network device 5 use the same encrypted network cable ports and are connected using a standard network cable. The characteristic of this decryption structure is that the upper and lower-end devices use the same encryption method; if either network device is removed, the network will be disconnected. This encryption has 1680 possible combinations.
[0026] Hybrid decryption structure such as Figure 5 As shown, the upper-end network device 3 and the lower-end network device 5 use different motherboards and Ethernet port jumper wire arrangements, and decryption is performed through a network cable with different wire sequences at both ends. The characteristic of the hybrid decryption structure is that the wire sequences of both the upper and lower-end devices and the network cable at both ends are completely changed; if any link is missing, the network cannot be connected. This encryption has 2,822,400 encryption combinations.
[0027] Coloring the network cable connectors enhances their anti-hacking capabilities. Figures 1-5 The colors of the network cable numbers are: 1 orange-white, 2 orange, 3 green-white, 4 blue, 5 blue-white, 6 green, 7 brown-white, and 8 brown. During encryption and decryption, the traditional pattern of network cable position and color is broken, allowing for customization of the cable's position and color. This enables a greater variety of encryption combinations. For example, in hybrid encryption / decryption, customizing the network cable position and color results in a larger number of encryption combinations. To ensure the security of the encryption equipment, the casings and computer network cards of the modified end network device 3 and the downstream network device 5 are secured with anti-tamper screws or hot melt glue, and warning stickers are affixed to prevent unauthorized disassembly.
[0028] This embodiment is applied to the Harbin Medical Insurance Internet Virtual Private Network, such as... Figure 6 As shown, based on the original "Internet + IP SecVPN" networking model, physical encryption upgrades were performed on the network equipment at all levels of the "Harbin Medical Insurance Internet Virtual Private Network" to form an effective network system to prevent unauthorized connections and theft, thus eliminating acts by criminals that infringe upon national and individual interests.
