Description

Technical Field

[0001] The present invention relates to the technical field of network security, and in particular to a special-shaped network physical isolation access kit and a use method thereof. Background Art

[0002] With the rapid development of information technology, the Internet has become an indispensable part of people's lives and work. However, network security issues are becoming increasingly serious, posing a huge threat to individuals, enterprises and society. In the field of network security, although traditional network security protection measures can ensure network security to a certain extent, they still have many shortcomings.

[0003] On the one hand, common network access devices often use standard universal interfaces in interface design, which allows attackers to exploit vulnerabilities in these universal interfaces for illegal access. For example, some hackers may easily access the network by imitating devices with standard interfaces or taking advantage of interface compatibility issues, thereby stealing sensitive information, implanting malware, or launching network attacks. This security risk based on the universality of interfaces poses a huge challenge to network security protection;

[0004] On the other hand, existing network security protection methods also have certain limitations in terms of data transmission security. Although software-level security measures such as firewalls and anti-virus software can prevent some network threats, the physical isolation and encryption processing of data during transmission are not perfect. In the absence of effective physical isolation measures, attacks from external networks may directly affect the security of internal networks, leading to serious consequences such as data leakage and system paralysis. At the same time, the strength and security of data encryption technology need to be improved to cope with increasingly complex network attack methods and ensure the confidentiality and integrity of data during transmission;

[0005] In addition, in terms of monitoring, the existing network security system lacks the ability to monitor the network operation status and data transmission in real time, and often fails to detect potential security threats and abnormal behaviors in a timely manner, causing irreparable losses to users;

Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0040] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0041] like Figure 1-Figure 6 As shown, an embodiment of the present invention provides a special-shaped network security physical isolation access kit, including a main component 1, the main component 1 includes a shell 11, a main control board 12, an interface module 13, a special-shaped socket 14, a customized plug 15, a plug sheet 16, a plug board 17, an elastic pin 18, a connection module 19, a connection line 20, a crystal plug 21, a physical isolation module 22, a security authentication module 23, a data encryption module 24 and a monitoring alarm module 25;

[0042] A main control board 12 is arranged inside the housing 11, and a plurality of interface modules 13 are arranged on the front of the upper surface of the main control board 12. A plurality of special-shaped sockets 14 are opened on the front surface of the housing 11, and a customized plug 15 is slidably connected to the inner side wall of the special-shaped socket 14, and a plug-in sheet 16 is arranged on the front of the lower surface of the customized plug 15. A plug-in board 17 is arranged on the rear of the inner bottom wall of the special-shaped socket 14, and a plurality of elastic pins 18 are arranged on the upper surface of the plug-in board 17, one end of the elastic pin 18 is electrically connected to the interface module 13, and the outer side wall of the elastic pin 18 is fitted and connected to the lower surface of the plug-in sheet 16. A connection module 19 is provided at the center of the rear part of the upper surface. The access end of the connection module 19 is electrically connected to a crystal plug 21 through a connection line 20. The end of the connection line 20 away from the connection module 19 passes through the center of the inner rear wall of the shell 11. A physical isolation module 22, a security authentication module 23, a data encryption module 24 and a monitoring alarm module 25 are provided in the middle of the upper surface of the main control board 12. The plug-in sheet 16 at the front of the lower surface of the customized plug 15 is fitted with the elastic pin 18 on the plug-in board 17 at the rear of the inner bottom wall of the special-shaped socket 14, thereby achieving electrical connection and facilitating data transmission.

[0043] Among them, the physical isolation module 22 is used to perform physical isolation processing on the data to ensure that the external network and the internal network are completely disconnected at the physical level, and only data that has passed the security authentication can be further transmitted;

[0044] The security authentication module 23 is used to authenticate the user's identity according to the authentication method set by the suite, such as fingerprint recognition, iris recognition, smart card authentication or password authentication. Only users who pass the security authentication can continue to transmit data;

[0045] The data is transmitted to the data encryption module 24, which uses a high-strength encryption algorithm to encrypt the data to ensure the confidentiality and integrity of the data during transmission;

[0046] The monitoring and alarm module 25 monitors the running status and data transmission of the suite in real time. If any abnormal behavior is found, such as illegal connection attempts, frequent authentication failures, data transmission abnormalities, etc., an alarm mechanism will be triggered immediately.

[0047] In one embodiment, specifically: the middle parts of both sides of the inner wall of the special-shaped socket 14 are fixedly connected with the limiting slide bar 26, and the middle parts of both sides of the customized plug 15 are provided with the limiting slide groove 27, and the inner wall of the limiting slide groove 27 is slidably connected to the outer wall of the limiting slide bar 26. The limiting slide grooves 27 on both sides of the customized plug 15 slide along the limiting slide bar 26, so as to limit the customized plug 15 and increase the stability of the insertion of the customized plug 15.

[0048] In one embodiment, specifically: a plug-in slot 28 is provided in the middle of the inner top wall of the special-shaped socket 14, a plug-in block 29 is provided in the middle of the upper surface of the customized plug 15, and the outer wall of the plug-in block 29 is slidably connected to the inner wall of the plug-in slot 28, and the plug-in block 29 on the customized plug 15 slides along the plug-in slot 28, thereby further increasing the stability of the insertion of the customized plug 15.

[0049] In one embodiment, specifically: a mounting hole 30 is provided in the middle of the inner top wall of the plug-in slot 28, the inner side wall of the mounting hole 30 is fixedly connected to a shell 31, the inner side wall of the shell 31 is slidably connected to a sliding block 32, a limiting block 33 is fixedly connected to the middle of the lower surface of the sliding block 32, the bottom of the limiting block 33 passes through the middle of the inner bottom wall of the shell 31, a limiting slot 34 is provided in the middle of the upper surface of the plug-in block 29, the lower part of the outer side wall of the limiting block 33 is fitted and connected to the inner side wall of the limiting slot 34, a pull rod 35 is fixedly connected at the center of the upper surface of the sliding block 32, the top of the pull rod 35 passes through the center of the inner top wall of the shell 31, and the top of the pull rod 35 is fixedly connected to a pull button 36. When the plug-in block 29 enters the plug-in slot 28, it will contact the limiting block 33. Due to the inclined surface 3 of the limiting block 33 and the plug-in block 29 8, the plug-in block 29 will push the limiting plug-in block 33 to move upward, so that the sliding block 32 slides upward in the shell 31, compressing the reset spring 37. When the customized plug 15 is fully inserted into the special-shaped socket 14, under the reset thrust of the reset spring 37, the limiting plug-in block 33 will move downward and insert into the limiting slot 34 in the middle of the upper surface of the plug-in block 29, so as to achieve the locking of the customized plug 15 in the special-shaped socket 14. At this time, a slight "click" sound can be heard, indicating that the connection is firm. By firmly locking the customized plug 15 in the special-shaped socket 14, it is prevented from accidentally falling off or being accidentally pulled out. For example, in some environments with extremely high requirements for network connection stability, such as financial transaction systems or military communication networks, it can ensure that the network connection will not be interrupted due to unexpected circumstances, thereby effectively ensuring the continuous and safe operation of the network.

[0050] In one embodiment, specifically: a reset spring 37 is sleeved on the outer wall of the pull rod 35, the top of the reset spring 37 is closely connected to the inner top wall of the shell 31 close to the outer side of the pull rod 35, and the bottom of the reset spring 37 is closely connected to the upper surface of the sliding block 32 close to the outer side of the pull rod 35. The reset spring 37 facilitates the use of the reset thrust to push the sliding block 32 and the bottom plug-in block 29 downward for reset.

[0051] In one embodiment, specifically: the bottom of the front surface of the limiting plug 33 and the rear surface of the plug-in block 29 are both provided with an inclined surface 38, and the inclined surface 38 of the limiting plug 33 and the plug-in block 29 are designed so that the plug-in block 29 can easily push the limiting plug 33 to move upward.

[0052] In one embodiment, specifically: a power module 39 is provided on one side of the rear portion of the upper surface of the main control board 12, the rear surface of the power module 39 passes through one side of the inner rear wall of the outer shell 11, and a power socket 40 is provided at the center of the rear surface of the power module 39. The power socket 40 is used to conveniently connect an external power source to power the access kit.

[0053] In one embodiment, specifically: signal indicator lights 41 are provided on both upper parts of the front surface of the housing 11 close to the special-shaped socket 14, and the signal indicator lights 41 are used to display the network connection status, network abnormal status, etc.

[0054] In one embodiment, specifically: connecting seats 42 are welded to the top of the four corners of the inner wall of the shell 11, and the upper surfaces of the four connecting seats 42 are fixedly connected to sealing covers 44 by screws 43. The outer side of the lower surface of the sealing cover 44 is fitted and connected to the rear part of the upper surface of the shell 11. The upper surface of the sealing cover 44 is provided with multiple heat dissipation grooves 45. The sealing cover 44 seals the top of the shell 11 to prevent dust from entering the interior. At the same time, the sealing cover 44 is made of aluminum alloy with good heat dissipation performance. The design of multiple heat dissipation grooves 45 on the sealing cover 44 increases the heat dissipation area, which is conducive to rapid heat dissipation.

[0055] In summary, the special-shaped network security physical isolation access kit proposed in the embodiment of the present invention performs well in terms of physical connection security, data transmission security, monitoring alarm, design innovation, applicability, and ease of maintenance and use, and can provide users with efficient and reliable network security protection.

[0056] like Figure 7 As shown, an embodiment of the present invention provides a method for using a special-shaped network security physical isolation access kit, including the following steps:

[0057] Step 1: Connect the power socket 40 on the power module 39 to the external power socket through the power cord and the adapted power plug, and insert the crystal plug 21 into the external network interface to ensure a stable connection;

[0058] Step 2: Align the customized plug 15 with the special-shaped socket 14 on the front surface of the housing 11 and insert it. During the insertion process, the plug block 29 will push the limit plug block 33 to move upward, so that the sliding block 32 slides upward in the housing 31 and compresses the return spring 37;

[0059] Step 3: After the customized plug 15 is completely inserted into the special-shaped socket 14, under the thrust of the return spring 37, the limit plug block 33 moves downward and is inserted into the limit slot 34 in the middle of the upper surface of the plug block 29, so as to limit the customized plug 15 and make the customized plug 15 firmly plugged into the special-shaped socket 14 to prevent accidental falling off or pulling out;

[0060] Step 4: After the connection is completed, the data is transmitted to the interface module 13 through the customized plug 15. The interface module 13 transmits the data to the physical isolation module 22, performs physical isolation processing on the data, and transmits the processed data to the security authentication module 23, and performs security authentication operation according to the authentication method set by the kit;

[0061] Step 5: After the authentication is passed, the data is transmitted to the data encryption module 24 for encryption processing. The encrypted data is transmitted through the circuit of the main control board 12, and is transmitted to the external network through the connection module 19, the connection line 20 and the crystal plug 21, or receives data from the external network for the opposite processing flow;

[0062] Step 6: During the data transmission process, the monitoring and alarm module 25 monitors the running status and data transmission status of the suite in real time. If any abnormal behavior is found, the alarm mechanism is immediately triggered, and the signal indicator light 41 displays an abnormal status;

[0063] Step 7: When removing the connected device, pull the pull button 36 to drive the pull rod 35 to move upward, so that the limiting plug block 33 is disengaged from the limiting slot 34 of the plug block 29, and pull out the customized plug 15 to remove the device.

[0064] In summary, the method for using a special-shaped network security physical isolation access kit provided by an embodiment of the present invention, through the various structural coordination between the customized plug 15 and the special-shaped socket 14, not only ensures that non-matching equipment cannot be accessed, but also uses a locking mechanism to prevent the customized plug 15 from accidentally falling off or being maliciously unplugged. Not only is the connection design unique and safe and reliable, and the connection steps are simple and convenient; in terms of data transmission, it has a comprehensive security processing flow, and provides multi-level security protection for data through physical isolation, multi-factor authentication and high-intensity encryption and other links in sequence. At the same time, the monitoring alarm module 25 monitors in real time, and promptly alarms and takes measures when abnormalities are found; the device removal operation is simple, and the customized plug 15 can be unplugged by pulling the button 36, which greatly improves the convenience and flexibility of use and the overall network security protection level.

[0065] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of various changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.

10. A method for using a special-shaped network security physical isolation access kit, applied to a special-shaped network security physical isolation access kit as claimed in any one of claims 1 to 9, characterized in that: The following steps are involved: Step 1: Connect the power socket (40) on the power module (39) to an external power socket via a power cord and an adapted power plug, and insert the crystal plug (21) into an external network interface; Step 2: Align the customized plug (15) with the special-shaped socket (14) on the front surface of the housing (11) and insert it. During the insertion process, the plug block (29) pushes the limit plug block (33) to move upward, so that the sliding block (32) slides upward in the housing (31) and compresses the return spring (37); Step 3: After the customized plug (15) is completely inserted into the special-shaped socket (14), under the thrust of the return spring (37), the limit plug block (33) moves downward and is inserted into the limit slot (34) in the middle of the upper surface of the plug block (29), thereby limiting the customized plug (15); Step 4: After the connection is completed, the data is transmitted to the interface module (13) through the customized plug (15), and the interface module (13) transmits the data to the physical isolation module (22), performs physical isolation processing on the data, and transmits the processed data to the security authentication module (23), and performs security authentication operation according to the authentication method set by the kit; Step 5: After the authentication is passed, the data is transmitted to the data encryption module (24) for encryption processing. The encrypted data is transmitted through the circuit of the main control board (12), and is transmitted to the external network through the connection module (19), the connection line (20) and the crystal plug (21), or the data is received from the external network to perform the reverse processing flow; Step 6: During the data transmission process, the monitoring and alarm module (25) monitors the running status and data transmission status of the suite in real time. If any abnormal behavior is found, the alarm mechanism is immediately triggered, causing the signal indicator light (41) to display an abnormal status; Step 7: When removing the connected device, pull the pull button (36) to drive the pull rod (35) to move upward, so that the limiting plug block (33) is disengaged from the limiting slot (34) of the plug block (29), and the customized plug (15) is pulled out to remove the device.
