[0025] The encryption server provided by the present invention is explained and illustrated in detail below with reference to the accompanying drawings.

[0026] This embodiment specifically discloses an encryption server, such as Figure 1-3 As shown, it includes a chassis and a motherboard 3, a hard disk 17, an encryption card 19 and a zeroing PCB board 30 inside the chassis. The hard disk 17, the encryption card 19 and the zeroing PCB board 30 are respectively connected to the motherboard 3. The motherboard 3 has a CPU, memory, a CPU cooling fan, a fiber optic interface, an RJ45 network interface, an indicator light, a PCIEx16 slot and a PCIEx8 slot.

[0027] The chassis consists of a chassis shell 1 and a chassis cover 2. The chassis shell 1 is a square structure with an opening on one side. The chassis cover 2 is mounted on the opening of the chassis shell 1 and is removably connected to the chassis shell 1. The chassis and chassis cover 2 are removably connected using bolts and nuts. The nuts are blind nuts to prevent attack by single-hinge probes. Existing server chassis use SGCC (hot-dip galvanized steel) steel plates. The chassis of this embodiment uses stainless steel, which has a hardness and toughness that exceeds SGCC by more than 30%, improving its resistance to physical attacks.

[0028] like Figure 2 and 3As shown, a zeroing logic lock hole 134 is provided on one side wall of the chassis housing 1. In this embodiment, the zeroing logic lock hole 134 is provided on the front side wall 13. A zeroing lock 10 is fixed in the zeroing logic lock hole 134. The zeroing lock 10 has two states, open and closed. The zeroing lock 10 is triggered by a key inserted into the zeroing logic lock hole 134. Figure 4 As shown, the outer surface of the side wall of the chassis shell 1 where the zero logic lock hole 134 is located is fixed with a chassis front panel 5, that is, the outer surface of the front side wall 13 is fixed with a chassis front panel 5, as shown in FIG. Figure 5 As shown, the front panel 5 of the chassis has a zeroing lock hole 53 corresponding to the zeroing logic lock hole 134. Holographic tape is affixed to the outer surface of the front panel 5 to cover the zeroing lock hole 53. The holographic tape is printed with a special pattern and leaves a mark after removal, making it unusable. When inserting a key into the zeroing lock 10 or the zeroing encryption card 19, the holographic tape covering the zeroing lock hole 53 must first be removed. The removal of the holographic tape leaves a mark, providing a mark and improving the encryption level.

[0029] A holographic tape is pasted on the joint of the chassis shell 1 and the chassis cover 2. The holographic tape needs to be torn off when the chassis cover 2 is opened. After the holographic tape is torn off, a trace is left, which makes a mark and improves the encryption level.

[0030] like Figure 2 and 3 As shown, a first normally closed limit switch 151 is fixed to the inner surface of one of the side walls of the chassis housing 1. The first normally closed limit switch 151 is located at the junction of the chassis housing 1 and the chassis cover 2. A second normally closed limit switch 152 is fixed to the inner surface of the side wall of the chassis housing 1 opposite to the first normally closed limit switch 151. The second normally closed limit switch 152 is located at the junction of the chassis housing 1 and the chassis cover 2. In this embodiment, the first normally closed limit switch 151 is fixed to the right side wall 14, and the second normally closed limit switch 152 is fixed to the left side wall 12. The first normally closed limit switch 151 and the second normally closed limit switch 152 are arranged opposite each other and are both arranged in the middle of the side walls. The first normally closed limit switch 151 and the second normally closed limit switch 152 are in a closed state when no external force is applied. The normally closed limit switch consists of an operating head and a main body. The operating head can move up and down. When the operating head is on the top, it is in a closed state, and when the operating head is on the bottom, it is in an open state. The normally closed limit switch is fixed on the inner wall of the chassis, and the operating head protrudes a small section of the side wall. When the chassis cover 2 is closed, the chassis cover 2 will press the operating head to move downward, turning from closed to open; when the chassis cover 2 is opened, the operating head is no longer pressed and moves upward, turning from open to closed.

[0031] A zeroing circuit is integrated on the zeroing PCB board 30, and the zeroing circuit is used to zero the encryption card 19. The input end of the zeroing circuit is electrically connected to the zeroing lock 10, the first normally closed limit switch 151 and the second normally closed limit switch 152 respectively, and the output end of the zeroing circuit is electrically connected to the encryption card 19. The first normally closed limit switch 151 and the second normally closed limit switch 152 are used to zero the encryption card 19 through the zeroing circuit when the chassis cover 2 is opened. The zeroing lock 10 zeroes the encryption card 19 through the zeroing circuit after being closed by the key.

[0032] The pins corresponding to the first normally closed limit switch 151 and the second normally closed limit switch 152 are connected to the zeroing circuit, and the closing signal of the normally closed limit switch will be transmitted to the encryption card 19 through the zeroing circuit to complete the zeroing encryption operation. When the chassis cover 2 is opened, at least one of the first normally closed limit switch 151 and the second normally closed limit switch 152 is closed, thereby zeroing the encryption card 19 through the zeroing circuit. The first normally closed limit switch 151 and the second normally closed limit switch 152 are arranged relative to each other, which can ensure that even if the chassis cover 2 is opened by one foot, it will be detected, thereby improving the encryption level. Normally closed limit switches can also be fixed on the other two side walls, that is, normally closed limit switches are fixed on all four side walls of the chassis, to further improve the encryption level and increase sensitivity.

[0033] The closing signal of the zero lock 10 is also transmitted to the encryption card 19 through the zero circuit, completing the zero encryption card 19 operation.

[0034] A third normally closed limit switch 153 is further fixed to the inner surface of the side wall of the chassis housing 1 where the first normally closed limit switch 151 and / or the second normally closed limit switch 152 are located. An alarm circuit is also integrated on the zeroing PCB board 30. The third normally closed limit switch 153 is electrically connected to the alarm circuit and is used to trigger an alarm circuit alarm when the chassis cover 2 is opened. In this embodiment, the third normally closed limit switch is fixed to the right side wall 14. There is a certain distance between the first normally closed limit switch 151 and the third normally closed limit switch 153. When the chassis cover 2 is opened, the encryption card 19 is reset to zero and an alarm can be triggered to alert the user.

[0035] The alarm circuit includes a safety switch, a buzzer, a power supply pin, and a switch pin connected in series. The switch pin is connected to a third normally closed limit switch 153. When the third normally closed limit switch 153 closes, the buzzer is triggered to sound an alarm. The power supply pin is a 5V power supply pin. When the chassis cover 2 is installed, the third normally closed limit switch 153 is in the open state and does not trigger the alarm circuit's buzzer. When the chassis cover 2 is removed, the third normally closed limit switch 153 is in the closed state, triggering the buzzer to sound an alarm.

[0036] like Figure 2As shown, a temperature switch assembly 18 for detecting the temperature of the encryption card 19 is also provided in the chassis. The temperature switch assembly 18 is arranged between the hard disk 17 and the encryption card 19 and is closer to the encryption card 19, and can be in contact with the encryption card 19. The temperature switch assembly 18 is electrically connected to the input end of the zeroing circuit. The temperature switch assembly 18 is used to zero the encryption card 19 through the zeroing circuit when the temperature exceeds the threshold range. In this embodiment, the temperature switch assembly 18 includes a high-temperature switch 181 and a low-temperature switch 182. The high-temperature switch 181 and the low-temperature switch 182 are fixed on a temperature bracket 183. The temperature bracket 183 is fixedly connected to the bottom wall of the chassis shell 1 by bolts and nuts. The nuts are blind hole nuts to prevent attacks from single-hinge probes. When removing the temperature switch assembly 18, it is necessary to first open the chassis cover 2. Opening the chassis cover will zero the encryption card 19 and improve the encryption level.

[0037] High-temperature switch 181 has an accuracy of ±3°C and a trigger temperature of 60°C. It is open at room temperature and closed when the temperature exceeds 60°C. The closing signal from high-temperature switch 181 is transmitted to encryption card 19 via the zeroing circuit, completing the zeroing encryption operation. Low-temperature switch 182 has an accuracy of ±3°C and a trigger temperature of -5°C. It is open at room temperature and closed when the temperature drops below -5°C. The closing signal from low-temperature switch 182 is transmitted to encryption card 19 via the zeroing circuit, completing the zeroing encryption operation.

[0038] In this embodiment, the zeroing circuit includes six input pins and one output pin. The six input pins are connected in parallel and then in series with the output pin. Five input pins are connected to the zeroing lock 10, the first normally closed limit switch 151, the second normally closed limit switch 152, the high temperature switch 181, and the low temperature switch 182, respectively. The remaining input pin is used as a backup, and the output pin is connected to the encryption card 19. When any of the zeroing lock 10, the first normally closed limit switch 151, the second normally closed limit switch 152, the high temperature switch 181, and the low temperature switch 182 completes the closing operation, it triggers the encryption card 19 to complete the zeroing operation.

[0039] like Figure 5 As shown, the front panel 5 of the chassis has a power switch hole 51, a USB hole 52, a zero lock hole 53, a fiber optic network port opening 54, an RJ45 network interface opening 55, a screen opening 56 and an indicator light opening 57. Figure 4 As shown, the chassis front panel 5 is fixed on the outer surface of the front side wall 13 of the chassis shell 1, and is fixed outside the chassis by bolts and blind hole nuts. One of the bolts and blind hole nuts is installed from the inside of the chassis. The chassis cover 2 must be opened to disassemble and install the chassis front panel 5.

[0040] like Figure 2 、 3As shown in FIG6 , the rear side wall 11 of the chassis housing 1 is provided with an air outlet 111, and the front side wall 13 is provided with a screen hole 131, an IO hole 132, an expansion drawer hole 133, a zeroing logic lock hole 134, and a fixing plate hole 135. The zeroing logic lock hole 134 on the front side wall 13 corresponds to the zeroing lock hole 53 on the chassis front panel 5, and the screen hole 131 on the front side wall 13 corresponds to the screen opening 56 on the chassis front panel 5. The screen 130 passes through the screen hole 131 and the screen opening 56 to exit the chassis.

[0041] Mainboard 3 is installed within the chassis and secured to front sidewall 13 of chassis housing 1 using bolts and blind nuts. The fiber optic port, RJ45 network port, and indicator light on mainboard 3 are located on front sidewall 13 of chassis housing 1 and extend out of the chassis through IO port 132. The fiber optic port corresponds to fiber optic network port opening 54 on chassis front panel 5, the RJ45 network port corresponds to RJ45 network port opening 55 on chassis front panel 5, and the indicator light corresponds to indicator light opening 57 on chassis front panel 5.

[0042] The PCIe expansion slot 4 is connected to the PCIEx 16 slot on the motherboard 3 and is secured to the chassis 1 on one side of the motherboard 3 via bolts and blind nuts. The PCIe expansion slot 4 converts one PCIEx 16 slot into two PCIEx 8 slots and facilitates connecting expansion modules, which are secured to the PCIe expansion drawer. The PCIe expansion drawer includes a first PCIe expansion drawer 281 and a second PCIe expansion drawer. The first PCIe expansion drawer 281 is covered by a first PCIe expansion drawer cover 291, and the second PCIe expansion drawer is covered by a second PCIe expansion drawer cover 292. The first and second PCIe expansion drawers 281 and 281 are installed and removed through the expansion drawer holes 133 on the front side wall 13. An expansion slot front panel 6 is mounted on the outer surface of the front side wall, corresponding to the expansion drawer holes 133. The expansion slot front panel 6 must be removed before removing the first and second PCIe expansion drawers 281 and 281.

[0043] like Figure 3 As shown, the switch USB fixing plate 110 is fixed to the front side wall 13 of the chassis housing 1. This plate is used to secure the switch PCB 8 and the USB_PCB 9. The switch USB fixing plate 110 corresponds to the fixing plate holes 135 on the front side wall. The switch USB fixing plate 110 has two sides, A and B. Side A is closer to the front side wall 13 of the chassis housing 1, and side B is closer to the interior of the chassis. The switch USB fixing plate 110 is fixed perpendicular to the front side wall 13, while side B is farther away from the front side wall 13. Side B of the switch USB has an upwardly angled hem, parallel to the front side wall. The hem reaches the bottom surface of the front shielding reinforcement plate 7 to prevent attack by a single-hinge probe.

[0044] The switch PCB 8 is mounted on the switch USB fixing plate 110 . The switch PCB 8 is connected to the switch pins on the mainboard 3 via a flat cable. The switch PCB 8 extends out of the chassis through the fixing plate hole 135 on the front side wall 13 , corresponding to the power switch hole 51 on the front panel 5 of the chassis.

[0045] The USB_PCB board 9 is installed on the switch USB fixing plate 110. The USB_PCB board 9 is connected to the encryption card 19 through a USB cable. The USB_PCB board 9 extends out of the chassis through the fixing plate hole 135 on the front side wall 13, corresponding to the USB hole 52 on the front panel 5 of the chassis.

[0046] The encryption card 19 is connected to the PCIEx8 slot of the mainboard 3 and is fixed to the encryption card bracket 20 by bolts and blind hole nuts. The encryption card bracket 20 is fixed to the chassis shell by bolts and blind hole nuts. The encryption card 19 is in the middle of the chassis.

[0047] There may be a gap greater than 0.3 mm between the switch PCB board 8 and the USB_PCB board 9 and the power switch hole 51 and USB hole 52 on the chassis front panel 5, and there may be a gap between the USB interface and the front side wall. Therefore, a folded edge is added to the side of the switch USB fixing plate 110B to prevent attack by a single hinge probe.

[0048] like Figure 2 and 3 As shown, a first air inlet assembly 122 is fixed to the inner surface of one side wall of the chassis shell 1, and a second air inlet assembly 142 is fixed to the inner surface of the side wall of the chassis shell 1 opposite the first air inlet assembly 122.

Above the optical fiber interface on the main board 3 ( Figure 3 A heat dissipation hole is provided on the left side of the optical fiber interface in the front side wall. A light port shielding plate 120 for shielding the heat dissipation hole is fixed on the inner surface of the side wall of the chassis shell 1 opposite to the heat dissipation hole. In this embodiment, the light port shielding plate 120 is fixed on the inner surface of the front side wall 13. The light port shielding plate 120 faces the heat dissipation hole. There is a spacing distance ( Figure 3 The middle optical port shielding plate 120 is located above the heat dissipation hole to avoid blocking the heat dissipation hole and prevent the attack of the single hinge probe.

The AC end is close to the front side wall 13 of the chassis shell 1, and the DC end is close to the motherboard 3. The power supply 26 consists of multiple power modules and a power shell. Multiple power modules are installed in parallel inside the power shell. The power module baffle is fixed to the AC end of the power supply 26 and is fixed to the left side wall 12 of the chassis shell 1 by bolts and blind hole nuts. When installing or removing the power module in the battery shell, the power module baffle must be removed in advance.

[0053] A fan 22 is fixed on the inner bottom wall of the chassis shell 1, and an air outlet 111 is provided on the side wall of the chassis shell 1 opposite to the air outlet path of the fan 22. An air outlet assembly is provided between the air outlet 111 and the fan 22, and an air outlet oblique baffle is fixed on the air outlet assembly.
