Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of cryptographic machine protection equipment, and more specifically, to a cryptographic machine with a disconnection alarm structure. Background Technology
[0002] Server cryptographic machines possess functions such as data encryption / decryption, signing, signature verification, MAC, and hashing. They support SM1 / SM2 / SM3 / SM4 / SM9 and ZUC national cryptographic algorithms, addressing security concerns related to the confidentiality, integrity, validity, and non-repudiation of sensitive information. As a high-end commercial basic cryptographic product, server cryptographic machines provide high-performance data encryption / decryption services for secure information transmission systems. They also serve as key cryptographic devices and core components for host data security storage systems, identity authentication systems, and symmetric and asymmetric key management systems, demonstrating broad system application potential. They can be widely used in secure business application systems across industries such as banking, insurance, securities, transportation, postal services, e-commerce, and mobile communications.
[0003] The structure of a server cryptographic machine mainly includes several USB ports, network ports, and VGA interfaces. In actual use, these interfaces are used for data exchange, but they are also easily connected to external hardware devices, such as USB flash drives, which can steal confidential data from the server cryptographic machine through internal software programs. This is difficult to detect and address in a timely manner. Therefore, a dedicated offline alarm structure needs to be designed for the server cryptographic machine. Utility Model Content
[0004] The purpose of this invention is to provide a cryptographic machine with a disconnection alarm structure. This disconnection alarm structure can provide timely alarm feedback when a certain line of the server cryptographic machine is disconnected, thereby improving the practical security and reliability of the cryptographic machine and preventing external hardware devices from intruding through the cryptographic machine's interface.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A cryptographic machine with a disconnection alarm structure includes a cryptographic machine. An I / O cover plate is fixedly connected to the rear side of the cryptographic machine by a physical lock cylinder. The surface of the I / O cover plate is processed with heat dissipation holes, a fan bracket, and a power interface. The surface of the I / O cover plate below the heat dissipation holes is processed with a video transmission interface, a network port, and a data transmission interface. A disconnection detection cover plate is fixedly connected to the outer side of the video transmission interface, network port, and data transmission interface of the I / O cover plate. The surface of the disconnection detection cover plate is processed with through slots corresponding to the positions of the video transmission interface, network port, and data transmission interface on the I / O cover plate. A network cable, a data cable, or a video cable passes through the through slots.
[0007] As a further optimization of this solution, connecting screws are provided at the four corners of the back of the disconnection detection cover. The connecting screws pass through the I / O cover and are connected and limited by the nuts on the inside. The detection box is fixed to the back of the I / O cover with screws. The surface of the detection box is provided with control buttons, display screen, buzzer and battery compartment. The main board inside the detection box is provided with controller, memory and signal transmitter. The battery compartment is connected to an external charging cable. The signal line of the disconnection detection cover passes through the I / O cover and is connected to the interface on the side of the detection box.
[0008] As a further optimization of this solution, a groove is formed on the upper side surface of the through groove, and symmetrical connecting seats are provided on the left and right sides of the front end of the groove. A reset spring shaft is installed between the connecting seats, and a pressure plate is installed on the reset spring shaft. Symmetrical pressure sensors are provided on the left and right sides of the rear end of the groove.
[0009] As a further optimization of this solution, after the pressure plate is inserted and pressed down by the outer shell of the network cable, data cable or video cable, it is rotated and pressed tightly onto the pressure sensor, and the pressure sensor is connected in parallel to the signal line.
[0010] As a further optimization of this solution, the charging cable is connected to the power supply interface on the internal motherboard of the cryptographic machine.
[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows:
[0012] This invention features a disconnection detection cover with a through-slot. Inside the through-slot, a resetting and rotatable pressure plate and a pressure sensor are designed to detect whether the network cable, data cable, or video cable of the cryptographic device has been unplugged. Specifically, when a network cable, data cable, or video cable is detected to be unplugged, the pressure plate at that location moves away from the pressure sensor under the elastic force of the reset spring shaft. The pressure sensor generates a change in current signal, which is transmitted to the detection box. The detection box then issues an audible alarm via a buzzer, which can be emitted from inside the heat dissipation holes. Additionally, it can wirelessly transmit the disconnection information to the administrator's mobile device via a signal transmitter. This facilitates timely detection of disconnection situations, improves the security and reliability of the cryptographic device, and prevents external hardware devices from intruding through the cryptographic device's interface.
[0013] This invention incorporates a battery compartment structure on the detection box, allowing a rechargeable battery to be placed inside. Even in the event of a power outage, it can detect disconnection actions for an extended period. Combined with a charging cable structure, the rechargeable battery is charged when the motherboard is powered normally, ensuring the detection box operates normally for an extended period.

Detailed Implementation
[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.
[0020] To address the problem that existing cryptographic machine interfaces are easily connected to by external hardware devices, allowing them to steal confidential data from the server's cryptographic machine and making it difficult to detect in a timely manner;
[0021] like Figure 1 As shown, this application includes a cryptographic machine 1. An I / O cover plate 2 is fixedly connected to the rear side of the cryptographic machine 1 by a physical lock cylinder 3. The surface of the I / O cover plate 2 is processed with heat dissipation holes 4, a fan bracket 5 and a power interface 6. The surface of the I / O cover plate 2 below the heat dissipation holes 4 is processed with a video transmission interface 7, a network port 8 and a data transmission interface 9. A disconnection detection cover plate 10 is fixedly connected to the outer side of the video transmission interface 7, network port 8 and data transmission interface 9 of the I / O cover plate 2.
[0022] like Figure 3 As shown, the surface of the disconnection detection cover 10 is machined with through slots 20 that correspond to the positions of the video transmission interface 7, network port 8 and data transmission interface 9 on the I / O cover 2. The network cable 11, data cable 12 or video cable passes through the through slots 20.
[0023] like Figure 2 and Figure 3As shown, connecting screws 15 are provided at the four corners of the back of the disconnection detection cover. The connecting screws 15 pass through the I / O cover 2 and are connected and limited by the nuts 16 on the inside. The detection box 13 is fixed to the back of the I / O cover 2 by screws 14. The surface of the detection box 13 is provided with control buttons, display screen, buzzer 26 and battery compartment 17. The main board inside the detection box 23 is provided with controller, memory and signal transmitter. The battery compartment 17 is connected to the external charging cable 18. The signal line 19 of the disconnection detection cover 10 passes through the I / O cover 2 and is connected to the side interface of the detection box 13.
[0024] like Figure 4 As shown, a groove 21 is provided on the upper side surface of the through groove 20. Symmetrical connecting seats 22 are provided on the left and right sides of the front end of the groove 21. A reset spring shaft 23 is installed between the connecting seats 22. A pressure plate 24 is installed on the reset spring shaft 23. Symmetrical pressure sensors 25 are provided on the left and right sides of the rear end of the groove 21.
[0025] Specifically, the charging cable 18 is connected to the power supply interface on the internal motherboard of the cipher machine 1. When the motherboard of the cipher machine 1 is powered normally, it charges the rechargeable battery, so that the detection box 13 can also supply power to the pressure sensor 25, the signal transmitter and the buzzer 26 when the motherboard is powered off, and detect the disconnection action for a long time.
[0026] During operation, the manager can remove the I / O cover plate 2 by opening the physical lock cylinder 3 with a key. The disconnection detection cover plate 10 is then installed on the I / O cover plate 2 using nuts 16, and the detection box 13 is installed using screws 14. By operating the control buttons and observing the display screen to set the relevant detection parameters, the I / O cover plate 2 is reinstalled. Figure 1 As shown, after the network cable 11 and data cable 12 are plugged in, their outer shells are inserted inward and pressed down, causing the pressure plate 24 to rotate and press against the pressure sensor 25. At this time, it is considered that there is no disconnection. When the network cable 11 and data cable 12 are pulled out, the pressure plate 24 moves away from the pressure sensor 25 under the elastic force of the reset spring shaft 23. The pressure sensor 25 generates a change in current signal and transmits it to the detection box 13. The detection box 13 provides an audible alarm through the buzzer 26, and the sound can be transmitted from inside the heat dissipation hole 4. On the other hand, it can wirelessly transmit the disconnection information to the mobile device of the management personnel through the signal transmitter, so as to facilitate timely detection of disconnection and acquisition of alarm information.
