[0027] Hereinafter, the embodiments of the present application will be described in detail with reference to the accompanying drawings and in conjunction with the embodiments.

[0028] It should be noted that the terms "first", "second" and the like in the description and claims of the present application and the above drawings are used to distinguish similar objects, and do not necessarily indicate a specific order or sequence.

[0029] The method embodiments provided in the embodiments of the present application can be executed in a mobile terminal, a computer terminal or a similar computing device. Taking the case of running on a mobile terminal, Figure 1 is a hardware structure block diagram of a mobile terminal of a management method of a magnetic key according to an embodiment of the present application. As shown in Figure 1 , the mobile terminal can include one or more (only one is shown in Figure 1 ) processor 102 (the processor 102 can include but not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA) and a memory 104 for storing data, wherein the above-mentioned mobile terminal can also include a transmission device 106 for communication function and an input and output device 108.

For example, the mobile terminal can also include more or less components than those shown in Figure 1 , or have a different configuration from Figure 1 .

[0030] The memory 104 can be used to store computer programs, for example, software programs and modules of application software, such as the computer program corresponding to the management method of the magnetic key in the embodiments of the present application. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, that is, implements the above-mentioned method. The memory 104 can include a high-speed random access memory, and can also include a non-volatile memory, such as one or more magnetic storage devices, flash memories, or other non-volatile solid-state memories. In some examples, the memory 104 can further include a memory remotely arranged with respect to the processor 102, which can be connected to the mobile terminal through a network.

[0031] The transmission device 106 is configured to receive or send data via a network. The network can include a wireless network provided by a communication provider of the mobile terminal. In one embodiment, the transmission device 106 includes a network interface controller (NIC) configured to connect to other network devices via a base station to communicate with the Internet. In one embodiment, the transmission device 106 can be a radio frequency (RF) module configured to communicate with the Internet via a wireless network.

[0032] In the present embodiment, a management method of a magnet key for the mobile terminal is provided, Figure 2 is a flow chart of a management method of a magnet key according to the present embodiment, as shown in the figure, the flow includes the following steps: Figure 2

[0033] In step S202, the host computer acquires a secret key package sent by a management system and decodes the secret key package to obtain a secret key of the magnet key, an effective time of the secret key, and a geographical location of the secret key. The effective time indicates a time range during which the secret key is effective. The geographical location indicates a geographical range during which the secret key is effective.

[0034] Specifically, the switch is a device for network communication and a physical guarantee for network communication security. Therefore, after the switch manufacturer completes the switch device, the manufacturer usually does not allow the customer to disassemble the switch. In order to prevent the switch case from being opened in violation of rules or disassembled by the customer, the switch case of the present application is locked by a magnet locking mechanism. The magnet locking mechanism can be opened only under the action of a magnet key. The polarity of the magnet key can be changed. The change of the polarity of the magnet key depends on the secret key of the magnet key. The magnet key is physically connected to the host computer, for example, by a USB method. The secret key is acquired from the management system by the host computer. The management system can also set the effective time of the secret key and the geographical range of the secret key to limit the time during which the secret key is effective and the geographical location during which the secret key is effective, thereby enhancing the security of the secret key.

[0035] In step S204, the host computer acquires a current time and a current geographical location, determines whether the current time is within the effective time, and determines whether the current geographical location is within the geographical location. The current geographical location is the geographical location of the host computer.

[0036] ​Specifically, the upper computer is generally a mobile phone or a computer or the like. The upper computer determines the geographical position of the upper computer through the GPS function of the upper computer, obtains the current geographical position, and acquires the current time of the upper computer. Then, the upper computer determines whether the current time is within the above-mentioned effective time range and whether the current geographical position is within the above-mentioned effective geographical position range, to determine whether the current opening condition of the switch cabinet is met.

[0037] In step S206, when the current time is within the above-mentioned effective time range and the current geographical position is within the above-mentioned effective geographical position range, the upper computer transmits the secret key to the magnet key, so that the polarity of the plurality of electromagnetic columns in the magnet key changes, thereby opening the magnet locking mechanism of the switch cabinet. The magnet key includes a plurality of electromagnetic columns and non-electromagnetic columns.

[0038] Specifically, when the current time and the current geographical position meet the above-mentioned effective time range and the effective geographical position range, the magnet key opens the magnet locking mechanism of the switch cabinet by using the principle that opposite poles attract and like poles repel. During the manufacturing process of the switch cabinet, the switch manufacturer stores the polarity information of the magnet locking mechanism of the switch cabinet into a management system, and stores the corresponding polarity information of the magnet key, i.e., the secret key, into the management system. The management system (such as an ERP system) in the enterprise manages and controls the secret key information. As a way of encrypting the magnet key, the magnet key includes a plurality of electromagnetic columns and non-electromagnetic columns. The electromagnetic column includes a magnetic column, and the non-electromagnetic column can be an iron column. The polarity of the electromagnetic column can change, i.e., it can be encoded. The polarity of the magnetic column is fixed and cannot change. The iron column does not have polarity, i.e., it is empty. In actual application, the number of electromagnetic columns is generally two for ease of management, but it can also be multiple according to different actual application scenarios.

[0039] By the above steps, since the secret key of the magnet key is obtained by the host computer, the host computer needs to determine whether the current time and the current location are within the effective time and the geographical location range of the secret key before sending the secret key to the magnet key. If the current time and the current location are within the effective time and the geographical location range of the secret key, the host computer sends the secret key of the magnet key to the magnet key to open the magnet locking mechanism of the switch cabinet. Compared with the prior art in which the cabinet of the switch is sealed by a label or a screw, which may be illegally disassembled, the application transmits the secret key to the magnet key in real time through the host computer, and limits the use time and the use location of the magnet key by determining whether the current time of the host computer is within the effective time range of the secret key and whether the current geographical location is within the geographical location range of the secret key. Only when the above conditions are met, the cabinet can be opened by the magnet key. Therefore, the problem that the cabinet of the switch may be opened without permission is solved, and the effect of preventing the cabinet of the switch from being illegally opened is achieved.

[0040] The execution subject of the above steps can be a server, a terminal, etc., but is not limited thereto.

[0041] In order to determine the polarity of the magnet key, in some optional embodiments, the magnet key further comprises a plurality of electromagnetic coils, the electromagnetic columns and the electromagnetic coils one-to-one correspond, and the polarity of the plurality of electromagnetic columns in the magnet key is changed triggered by the change of the current direction of the plurality of electromagnetic coils. The current direction of the electromagnetic coil is forward or reverse, and the forward or reverse of the electromagnetic coil is controlled by the secret key of the magnet key. This method controls the current direction of the electromagnetic coil in the magnet key and then controls the polarity of the magnetic column in the electromagnetic key through the secret key, so that the polarity of the magnetic column in the magnet key can be flexibly controlled according to the secret key.

[0042] Specifically, each electromagnetic column in the magnet key corresponds to an electromagnetic coil, and the magnetic column is made of a magnet. After the magnet key is physically connected with the host computer, the host computer can energize the coil in the magnet key. The host computer controls the flow direction of the coil current in the magnet key through the secret key. For example, the polarity of the magnetic column is divided into N pole and S pole, so the secret key decoding can consist of a string of numbers composed of 0 and 1. The coil current direction corresponding to the number 0 is clockwise, assuming that clockwise is forward, the corresponding magnetic column polarity is N pole, and the coil current direction corresponding to the number 1 is counterclockwise, i.e. reverse, and the corresponding magnetic column polarity is S pole. In the specific application process, the polarity of the magnetic column can be determined by using the right-hand screw rule for the coil current direction. It should be noted that the secret key is invisible throughout the process and is completely controlled by the system in-band.

[0043] In an example embodiment, the above-mentioned magnet locking mechanism of the above-mentioned switch cabinet is opened when a plurality of the above-mentioned electromagnetic posts and a plurality of the above-mentioned non-electromagnetic posts in the above-mentioned magnet key are in one-to-one correspondence with a plurality of contacts in the above-mentioned magnet locking mechanism of the above-mentioned switch cabinet, wherein the above-mentioned magnet locking mechanism on the above-mentioned switch cabinet includes a plurality of the above-mentioned contacts, the above-mentioned contacts include electromagnetic contacts and empty contacts, the above-mentioned electromagnetic contacts are in one-to-one correspondence with each of the above-mentioned electromagnetic posts or each of the above-mentioned magnetic posts in the above-mentioned magnet key and have the same electromagnetic polarity, and the above-mentioned empty contacts are contacts without magnetism and are in one-to-one correspondence with each of the above-mentioned non-electromagnetic posts in the above-mentioned magnet key. This method makes the magnet key and the magnet locking mechanism contact, that is, the electromagnetic posts, the non-electromagnetic posts in the magnet key and the contacts of the corresponding magnet locking mechanism contact, so that the switch cabinet magnet locking mechanism can be opened by using the principle that the same poles repel each other and the opposite poles attract each other.

[0044] Specifically, after the magnet key obtains the secret key sent by the upper computer, the polarity of each electromagnetic post in the magnet key is determined. The magnet key is brought into contact with the magnet locking mechanism of the cabinet, so that each electromagnetic post, magnetic post and iron post of the magnet key is in contact with each contact of the corresponding magnet locking mechanism. As mentioned above, the polarity of each contact of the magnet locking mechanism has been stored in the management system (such as an ERP system) of the manufacturer before the switch cabinet is shipped, and the secret key of the corresponding magnet key is also stored in the management system and sent to the magnet key. Therefore, the polarity of each electromagnetic post in the magnet key is necessarily the same as the polarity of each contact of the magnet locking mechanism, and the switch cabinet magnet locking mechanism is opened under the principle that the same poles repel each other.

[0045] In order to facilitate the recording and management of the event that the switch cabinet is opened, in an example embodiment, after the above-mentioned upper computer transmits the above-mentioned secret key to the above-mentioned magnet key, the above-mentioned upper computer further sends the above-mentioned current time and the above-mentioned current geographic location to the above-mentioned management system, so that the above-mentioned management system records the time and location at which the above-mentioned magnet key opens the above-mentioned magnet locking mechanism. This method sends the current time and the current geographic location to the management system, so that the management system can record the opening time and geographic location of the switch cabinet.

[0046] Specifically, in order to ensure the safety of the switch equipment, the cabinet of the switch is generally not allowed to be opened. Even if it needs to be opened, it needs to be reported to the management system. Therefore, the upper computer needs to upload or send the opening time and the opening geographic location of the cabinet to the management system, and the administrator can query and control the cabinet opening event through the management system.

[0047] In an example embodiment, the host computer obtains the secret key package sent by the management system in the case that the management system receives the disassembly application and issues the disassembly instruction. This method needs the management system to approve the disassembly application before starting the switch, and only in the case that the disassembly application is approved, the subsequent conditions can be judged, which can further limit the conditions of starting the switch and ensure the safety of the switch equipment.

[0048] Specifically, in actual application, if the user needs to disassemble the switch, the user needs to apply for disassembly to the management system of the switch manufacturer, that is, to initiate a disassembly application. After obtaining the consent of the management system of the manufacturer, the manufacturer will appoint a special officer to open the switch on site, that is, to obtain the secret key package sent by the management system through the host computer, and to verify whether the current time and the current geographic location are within the scope of the effective time and the geographic location of the secret key. If the above conditions are within the scope, the host computer is connected with the magnet key, the current direction of the coil in the magnet key is changed according to the secret key, the polarity of the magnetic column in the magnet key is determined, and after the magnetic column of the magnet key contacts the contact of the magnet locking mechanism, the cabinet of the switch is opened.

[0049] In order to improve the security of the secret key, in an example embodiment, the host computer obtains the secret key package sent by the management system by converting the secret key of the magnet key, the effective time of the secret key and the geographic location of the secret key into a machine code format secret key package and sending it to the host computer. This method encodes and decodes the secret key package, which can further improve the security of the secret key package.

[0050] Specifically, since the administrator of the enterprise can set the effective time of the secret key and the geographic location of the secret key through the management system, for example, by inputting the secret key, the corresponding effective time of the secret key and the geographic location of the secret key, that is, the secret key package, through the human-computer interaction interface of the management system, and then the management system converts the secret key package into a machine code format, in order to ensure the security of the secret key package during transmission, the secret key package is converted into a machine code format secret key package by using the machine code compiling method of the switch manufacturer, and the machine code format secret key package is transmitted to the host computer. In this way, even if the machine code format secret key package is lost or damaged during transmission, since it cannot be decoded by any device other than the host computer, the security of the secret key package is ensured. After the secret key package is transmitted to the host computer, the host computer decodes the secret key package to obtain the secret key, the effective time of the secret key and the geographic location of the secret key.

[0051] In one example embodiment, the host computer obtains the key package sent by the management system and clears the key of the magnet key after the magnet locking mechanism is opened, and obtains the key in the case that the management system receives the next disassembly application and issues the next disassembly instruction. This method clears the key of the magnet key after the chassis of the switch is opened, so that the key can be used only once, further improving the security of the switch equipment.

[0052] Specifically, after the chassis of the switch is opened, in order to ensure that the magnet key uses the key to open the chassis of the switch again, the key of the magnet key is cleared, and in some optional embodiments, the polarity of the contact of the magnet locking mechanism of the chassis of the switch is also reset, and the polarity of the contact of the magnet mechanism after reset is stored to the management system. The corresponding key after resetting the contact is also stored to the management system, and the key after resetting is sent to the magnet key to open the chassis of the switch when opening the chassis of the switch is needed next time. This further improves the security of the chassis of the switch.

[0053] In order for those skilled in the art to more clearly understand the technical solutions of the present application, the implementation process of the management method of the magnet key of the present application will be described in detail below in conjunction with specific embodiments.

[0059] Through the description of the above embodiments, those skilled in the art can clearly understand that the method according to the above embodiments can be realized by means of software and a general hardware platform as required, and of course, it can also be realized by hardware, but in many cases, the former is a better embodiment. Based on such understanding, the technical solutions of the present application can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, magnetic disk, optical disk), and includes a plurality of instructions for making a terminal device (which can be a mobile phone, computer, server, or network device, etc.) execute the method described in the above embodiments.

[0060] A magnet key management device according to an embodiment of the present application is also provided in the present embodiment, which is used to implement the above-mentioned embodiments and preferred embodiments, and will not be described again. As used below, the term "module" can be a combination of software and / or hardware that implements a predetermined function. Although the device described in the following embodiments is preferably implemented in software, implementation of hardware, or a combination of software and hardware, is also possible and contemplated.

[0061] Figure 8 A structure block diagram of a magnet key management device according to an embodiment of the present application is shown in FIG. 1, which comprises: Figure 8

[0062] The acquisition module 22 is configured to acquire and decode the secret key package sent by the management system by the host computer to obtain the secret key of the magnet key, the effective time of the secret key, and the geographic location of the secret key, wherein the effective time of the secret key represents the time range in which the secret key can function, and the geographic location of the secret key represents the geographic location range in which the secret key can function.

[0063] Specifically, the switch is a device for network communication and is also a physical guarantee for ensuring the security of network communication. Therefore, after the switch manufacturer completes the switch device, the switch manufacturer usually does not allow the customer to disassemble the switch. In order to prevent the switch case from being opened in violation of rules or disassembled by the customer, the switch case of the present application is locked by a magnet locking mechanism. The magnet locking mechanism can only be opened under the action of the magnet key. The polarity of the magnet key can be changed, and the change of the polarity of the magnet key depends on the secret key of the magnet key. The magnet key is physically connected to the host computer, for example, by a method such as USB. The secret key is acquired from the management system by the host computer. The management system can also set the effective time of the secret key and the geographic range of the secret key to limit the time in which the secret key can function and the geographic location in which the secret key can function, thereby enhancing the security of the secret key.

[0064] The judgment module 24 is configured to acquire the current time and the current geographic location by the host computer, judge whether the current time is within the range of the effective time, and judge whether the current geographic location is within the range of the geographic location, wherein the current geographic location is the geographic location of the host computer.

[0065] Specifically, the host computer is generally a mobile phone or a computer device. The host computer locates the geographic location of the host computer by the GPS function of the host computer to obtain the current geographic location and acquire the current time of the host computer. Then, the host computer judges whether the current time is within the range of the effective time and whether the current geographic location is within the range of the geographic location to determine whether the current conditions meet the opening conditions of the switch case. ​

[0066] The transmission module 26 is configured to transmit the secret key to the magnet key to change the polarity of the plurality of electromagnetic columns in the magnet key, so as to open the magnet locking mechanism of the switch cabinet, when the current time is within the effective time range and the current geographic position is within the effective geographic position range, wherein the magnet key comprises a plurality of electromagnetic columns and non-electromagnetic columns.

[0067] Specifically, when the current time and the current geographic position meet the effective time range and the effective geographic position range, the magnet key opens the magnet locking mechanism of the switch cabinet by using the principle that opposite poles attract and like poles repel. During the manufacturing process of the switch cabinet, the switch manufacturer stores the polarity information of the magnet locking mechanism of the switch cabinet into the management system, and stores the corresponding polarity information of the magnet key, i.e., the secret key, into the management system. The management system (such as an ERP system) in the enterprise manages and controls the secret key information. As a way of encrypting the magnet key, the magnet key comprises a plurality of electromagnetic columns and non-electromagnetic columns. The electromagnetic column comprises a magnetic column, and the non-electromagnetic column can be an iron column. The polarity of the electromagnetic column can be changed, i.e., it can be encoded. The polarity of the magnetic column is fixed and cannot be changed. The iron column does not have polarity, i.e., it is empty. In actual application, the number of electromagnetic columns is generally two, but it can be more according to different application scenarios.

[0068] Through the above steps, since the secret key of the magnet key is obtained by the host computer, the host computer needs to determine whether the current time and the current position are within the effective time range and the effective geographic position range of the secret key before sending the secret key to the magnet key. If the current time and the current position are within the effective time range and the effective geographic position range of the secret key, the host computer sends the secret key of the magnet key to the magnet key to open the magnet locking mechanism of the switch cabinet. Compared with the method of sealing the cabinet of the switch with a label or a screw in the prior art, which can be illegally disassembled, the application transmits the secret key to the magnet key in real time by the host computer, and limits the use time and the use position of the magnet key by determining whether the current time of the host computer is within the effective time range of the secret key and whether the current geographic position is within the effective geographic position range of the secret key. Only when the above conditions are met, the cabinet can be opened by the magnet key. Therefore, the problem that the switch cabinet can be opened without permission is solved, and the effect of preventing the switch cabinet from being illegally opened is achieved.

[0069] In order to determine the polarity of the magnet key, in some optional embodiments, the magnet key in the above device further comprises a plurality of electromagnetic coils, the electromagnetic columns and the electromagnetic coils one-to-one correspond, and the polarity of the plurality of electromagnetic columns in the magnet key is changed by changing the current direction of the plurality of electromagnetic coils. The current direction of the electromagnetic coil is forward or reverse, and the electromagnetic coil is forward or reverse controlled by the secret key of the magnet key. This method controls the current direction of the electromagnetic coil in the magnet key through the secret key, and then controls the polarity of the magnetic column in the electromagnetic key. In this way, the polarity of the magnetic column in the magnet key can be flexibly controlled according to the secret key.

[0070] Specifically, each magnetic column in the magnet key corresponds to an electromagnetic coil. After the magnet key is physically connected with the upper computer, the upper computer can energize the coil in the magnet key. The upper computer controls the flow direction of the coil current in the magnet key through the secret key. For example: the polarity of the magnetic column is divided into N pole and S pole, so the secret key can be composed of a string of 0 and 1. The coil current direction corresponding to the number 0 is clockwise. Assuming that clockwise is forward, the corresponding magnetic column polarity is N pole, then the coil current direction corresponding to the number 1 is counterclockwise, that is, reverse, and the corresponding magnetic column polarity is S pole. In the specific application process, the polarity of the magnetic column can be determined by using the right-hand screw rule for the coil current direction. It should be noted that the secret key is invisible throughout the process and is completely controlled by the system in-band.

[0071] In one exemplary embodiment, the magnet locking mechanism of the above switch case in the above device is opened when the plurality of electromagnetic columns and the plurality of non-electromagnetic columns in the above magnet key are one-to-one corresponding contact with the plurality of contacts in the magnet locking mechanism of the switch case. The magnet locking mechanism on the switch case comprises a plurality of contacts, the contacts comprise electromagnetic contacts and empty contacts, the electromagnetic contacts are one-to-one corresponding to each of the electromagnetic columns or each of the magnetic columns in the magnet key and have the same electromagnetic polarity, and the empty contacts are non-magnetic contacts and are one-to-one corresponding to each of the non-electromagnetic columns in the magnet key. This method makes the magnet key and the magnet locking mechanism contact, that is, the electromagnetic column, the non-electromagnetic column in the magnet key and the contact of the corresponding magnet locking mechanism, so that the same pole repels and the opposite pole attracts. In this way, the magnet locking mechanism of the switch case can be opened.

[0072] Specifically, after the magnet key obtains the secret key sent by the host computer, the polarity of each electromagnetic column in the magnet key is determined. The magnet key is in contact with the magnet locking mechanism of the cabinet, so that each electromagnetic column, magnetic column and iron column of the magnet key is in contact with each contact point of the corresponding magnet locking mechanism. As mentioned above, the polarity of each contact point of the magnet locking mechanism has been stored in the manufacturer's management system before the switch is shipped, and the secret key of the corresponding magnet key is also stored in the management system and sent to the magnet key. Therefore, the polarity of each electromagnetic column in the magnet key is necessarily the same as the polarity of each contact point of the magnet locking mechanism. Under the principle of same polarity repelling each other, the magnet locking mechanism of the switch cabinet is opened.

[0073] In order to facilitate the recording and management of the event that the switch cabinet is opened, in an example embodiment, the above-mentioned device further comprises a sending module for the host computer to send the above-mentioned current time and the above-mentioned current geographic location to the above-mentioned management system, so that the above-mentioned management system records the time and location of the above-mentioned magnet key opening the above-mentioned magnet locking mechanism. The method sends the current time and the current geographic location to the management system, so that the management system can record the opening time and geographic location of the switch.

[0074] Specifically, in order to ensure the safety of the switch equipment, the cabinet of the switch is generally not allowed to be opened. Even if it needs to be opened, it needs to be reported to the management system. Therefore, the host computer needs to upload or send the opening time and opening geographic location of the cabinet to the management system, and the administrator can query and control the cabinet opening event through the management system.

[0075] In an example embodiment, the host computer in the above-mentioned device obtains the above-mentioned secret key package sent by the above-mentioned management system in the case that the above-mentioned management system receives the disassembly application and issues the disassembly approval instruction. This method needs the management system to approve the disassembly application before opening the switch. Only in the case that the disassembly application is approved, the subsequent conditions can be judged. This can further limit the conditions of opening the switch and ensure the safety of the switch equipment.

[0076] Specifically, in the actual application process, if the user needs to disassemble the machine, the user needs to apply to the switch manufacturer's management system for disassembly, that is, initiate a disassembly application. After obtaining the consent of the manufacturer's management system (such as an ERP system), the manufacturer will appoint a special agent to open the user's switch on site, that is, the host computer obtains the secret key package sent by the management system, and verifies whether the current time and the current geographic location are within the scope of the effective time and the effective geographic location of the secret key through the host computer. If the above conditions are within the scope, the host computer is connected with the magnet key, the current direction of the coil in the magnet key is changed according to the secret key, the polarity of the magnetic column in the magnet key is determined, and after the magnetic column of the magnet key contacts the contact of the magnet locking mechanism, the case of the switch is opened.

[0077] In order to improve the security of the secret key, in an example embodiment, the host computer in the above device obtains the secret key package sent by the management system is that the management system converts the secret key of the magnet key, the effective time of the secret key and the effective geographic location of the secret key into a machine code format secret key package and sends it to the host computer. This method encodes and decodes the secret key package, which can further improve the security of the secret key package.

[0078] Specifically, since the administrator of the enterprise can set the effective time of the secret key and the effective geographic location of the secret key through the management system, for example: input the secret key, the effective time of the secret key and the effective geographic location of the secret key, that is, the secret key package, through the human-computer interaction interface of the management system, and then the management system converts the secret key package into a machine code format. In order to ensure the security of the secret key package during transmission, the secret key package is converted into a machine code format secret key package by using the machine code compiling method of the switch manufacturer, and the machine code format secret key package is transmitted to the host computer. In this way, even if the machine code format secret key package is lost or damaged during transmission, since it cannot be decoded by any device other than the host computer, the security of the secret key package is ensured. After the secret key package is transmitted to the host computer, the host computer decodes the secret key package to obtain the secret key, the effective time of the secret key and the effective geographic location of the secret key.

[0079] In an example embodiment, the host computer in the above device obtains the secret key package sent by the management system is also obtained after opening the magnet locking mechanism, clearing the secret key of the magnet key, and receiving the next disassembly application and issuing the next consent disassembly instruction in the management system. This method clears the secret key of the magnet key after the case of the switch is opened, so that the secret key can only be used once, further improving the security of the switch device.

[0080] Specifically, after the chassis of the switch is opened, in order to ensure that the magnet key can open the chassis of the switch again by using the secret key, the polarity of the contact of the magnet locking mechanism of the chassis is reset in some optional embodiments, and the reset polarity of the contact of the magnet locking mechanism is stored to the management system again. The corresponding secret key after the reset of the contact is also stored to the management system. When the chassis of the switch needs to be opened next time, the secret key after the reset is sent to the magnet key to open the chassis of the switch. In this way, the security of the chassis of the switch is further improved.
