Description

[0002] At present, the default port is usually used for communication between the client and the server. For example, when the SSH (Secure Shell) communication protocol is used, port 22 is used by default, which is very easy to be scanned and cracked by malicious programs (such as viruses, Trojans, etc.). Therefore, related technologies propose that different ports can be used in different time periods, such as using port 13456 for a period of time and port 14980 for another period of time. However, the server needs to inform the client of the port number of the target port, otherwise the client will not be able to communicate with the server. In addition, if the server is transmitting data with the client when the port is switched, the data transmission will be interrupted, resulting in data transmission failure. Summary of the invention

[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described in combination with the embodiments below. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] At present, the existing port switching method has problems such as poor security and high probability of data transmission failure. Based on this, the present invention implements a communication port switching method, device, electronic device and storage medium, which can significantly improve the security and reliability of the communication port and effectively reduce the probability of data transmission failure.

[0035] To facilitate understanding of this embodiment, a communication port switching method disclosed in an embodiment of the present invention is first introduced in detail, which is applied to a port management server (abbreviated as Mgr) for switching different port functions. Figure 1 The flowchart of a method for switching a communication port is shown in FIG. 1 , and the method mainly includes the following steps S102 to S104:

[0036] Step S102, obtain the target port function, and send the target port function to the first end and the second end to be communicated respectively. The target port function is used to determine the target port, the first end can be the server end (referred to as Ser), and the second end can be the client end (referred to as Cli). In one embodiment, a plurality of initial port functions are pre-configured in the port management server, from which an initial port function can be randomly selected as an alternative port function, and each random variable in the alternative port function is assigned a value to obtain the target port function, thereby sending the target port function to the server end and the client end respectively, so that the server end and the client end temporarily store the target port function, and at this time the server end and the client end still communicate based on the target port determined by the current port function.

[0037] Step S104, when it is monitored that both the first end and the second end are in the switching ready state, the function switching instruction is sent to the first end and the second end respectively, so that the first end and the second end communicate based on the target port function. The switching ready state is also the state in which the target port can be run at any time. Optionally, when the server or the client receives the target port function, it can enter the switching ready state. At this time, the server and the client have the same target port function. The function switching instruction is used to instruct the server and the client to use the target port function to cover the current port function, so that the server and the client communicate based on the target port determined by the target port function.

[0038] The communication port switching method provided by the embodiment of the present invention can send a function switching instruction to the first end and the second end when it is monitored that the first end and the second end are in a switching ready state, so that the first end and the second end can determine the same target port for communication based on the same target port function, without the need for port synchronization between the first end and the second end, thereby significantly improving the security and reliability of the communication port and effectively reducing the probability of data transmission failure.

[0039] To facilitate understanding of the aforementioned target port function, an embodiment of the present invention provides an implementation method for obtaining the target port function, specifically:

[0040] (1) Determine an alternative port function from a plurality of pre-configured initial port functions. The alternative port function is related to the port switching period, and the alternative port function is provided with a plurality of random variables. The port switching period is used to characterize the period of switching the current port used by the first end and the second end. Exemplarily, the port switching period may be one day, one week, one month, etc., and may be specifically configured based on actual needs. In one embodiment, the alternative port function may be randomly selected from the initial port function. Exemplarily, the port function may be time-related, such as:

[0041] (1.1) port1 = (week n1 + first parameter) % second parameter + third parameter. This port function can change the target port number every day. Wherein, port1 is the port number, the port switching cycle is one week, and the current week (week n1) is used as the time parameter. At least one of the first parameter, the second parameter, and the third parameter is a random variable. Assuming that the first parameter is a random variable, and the second parameter and the third parameter are constants, then port1 = (week n1 + random variable) % 61 + 12345;

[0042] (1.2) port2 = (the n2th hour of the day + the fourth parameter) % the fifth parameter + the sixth parameter. This port function can change the target port number every hour. As above, port2 is the port number, the port switching cycle is one day, and the current time (the n2th hour) is used as the time parameter. At least one of the fourth parameter, the fifth parameter, and the sixth parameter is a random variable. Assuming that the fourth parameter is a random variable, and the fifth parameter and the sixth parameter are constants, then port2 = (the n2th hour of the day + the random variable) % 17 + 100002.

[0043] Exemplarily, it is assumed that a port function port1=(week n1+random variable)%61+12345 is randomly selected as an alternative port function.

[0044] (2) According to the port switching cycle and the variable value of the random variable in the alternative port function, the target port function is obtained. The target port function is recorded as func_new. In practical applications, each random variable has multiple random values ​​to choose from. For example, assuming that the above random variable is 12, the target port function is port1 = (week n1 + 12) % 61 + 12345.

[0045] On this basis, the embodiment of the present invention provides an implementation method of sending the target port function to the first end and the second end to be communicated respectively, specifically:

[0046] (I) Sending the target port function to the first end to be communicated, so that the first end determines the time parameter according to the port switching cycle of the target port function, and determines the target port according to the time parameter through the target port function. After the target port function is sent to the first end, and the first end and the second end are both in a switching ready state, a time parameter matching the port switching cycle can be selected, such as if the port switching cycle is one week, the time parameter is week n1, such as if the port switching cycle is one day, the time parameter is the n2th hour, and the time parameter is substituted into the target port function to obtain the port number of the corresponding target port.

[0047] (ii) sending the target port function to the second end to be communicated, so that the second end determines the time parameter according to the port switching cycle matched by the target port function, and determines the target port according to the time parameter through the target port function. In the specific implementation, the implementation process of determining the port number of the target port by the first end mentioned above can be referred to, and the embodiment of the present invention will not be repeated here.

[0048] In one implementation, if a response instruction fed back by the server or the client is received, it can be determined that both the first end and the second end are in a switching ready state, specifically:

[0049] (1) If the first response instruction fed back by the first end is received within the first preset time length, it is determined that the first end is in a switching ready state; conversely, if the first response instruction fed back by the first end is not received within the first preset time length, the target port function is sent to the first end again until the first response instruction fed back by the first end is received within the first preset time length. Exemplarily, assuming that the first preset time length is 5 minutes, and the first response instruction is "received", if the "received" instruction fed back by the server end is received within 5 minutes, it is determined that the server end is in a switching ready state, and if the "received" instruction fed back by the server end is not received within 5 minutes, the target port function is resent to the server end.

[0050] (2) If the second response instruction fed back by the second end is received within the first preset time length, it is determined that the second end is in the switching ready state. Conversely, if the second response instruction fed back by the second end is not received within the first preset time length, the target port function is sent to the second end again until the second response instruction fed back by the second end is received within the first preset time length. Exemplarily, assuming that the first preset time length is 5 minutes, and the second response instruction is "received", if the "received" instruction fed back by the client is received within 5 minutes, it is determined that the client is in the switching ready state. If the "received" instruction fed back by the client is not received within 5 minutes, the target port function is resent to the client.

[0051] In actual applications, if both the server and the client are in a ready-to-switch state, a function switching instruction can be sent to the server and the client, respectively, so that the server and the client can immediately apply the target port function. For example, assuming that the function switching instruction is "use the new function immediately", since both the server and the client have fed back the response instruction, indicating that the probability of the signal receiving and sending channel being normal is relatively high, "use the new function immediately" can also be sent successfully with a high probability, so that the server and the client can switch from the current port function to the target port function, and communicate based on the target port determined by the target port function, where the current port function is recorded as func_old.

[0052] Considering that if the target port function is directly used to cover the current port function, there will be a short-term situation where the port function is different, such as the target port function directly covers the function currently being used by the server, and it is immediately different from the function currently being used by the client, or if the target port function directly covers the function currently being used by the server, and the port management server is disconnected from the client, that is, the port management server cannot communicate with the client, at this time, the target port function cannot cover the function currently being used by the client, which will cause the situation that the client and the server are currently using different functions to last for a long time. Therefore, the embodiment of the present invention proposes that when the server and the client receive the target port function, the target port function will be temporarily stored, rather than directly using the target port function, and when the first end and the second end are both in a switching ready state, after receiving the function switching instruction, the target port function is used to cover the current port function, so that the function currently being used by the server is the same as the port function currently being used by the client. In addition, preparing the function may also take time, such as the client preparing a new function to be available, which may take 2 seconds; the server preparing a new function to be available, which may take 5 seconds, when the server and the client are both ready, they are covered at the same time, and the situation that the client and the server are currently using different functions at this time lasts for a short time.

[0053] Based on the above embodiments, the present invention provides another communication port switching method, which is applied to the first end. Figure 2 FIG. 1 is a flow chart of another method for switching a communication port, the method mainly comprising the following steps S202 to S204:

[0054] Step S202, receiving the target port function, and controlling the first end to be in a switching ready state. The target port function is used to determine the target port, and the switching ready state is a state in which the target port can be operated. In one embodiment, if the server receives the target port function, it will send a first response instruction to the port management server within a first preset time length, and enter the switching ready state, and the server will temporarily store the target port function.

[0055] Step S204, receiving a function switching instruction, controlling the first end and the second end to communicate through the target port; wherein the second end receives the target port function and is in a switching ready state. In one embodiment, the time parameter can be determined according to the port switching cycle matched by the target port function, and then the target port is determined according to the time parameter by the target port function, thereby controlling the first end and the second end to communicate through the target port. Exemplarily, assuming that the target port function is port1=(week n1+12)%61+12345, wherein the port switching cycle matched by the target port function is determined to be every day, and the time parameter is an integer between 1 and 7, if the current time is Friday, the time parameter is determined to be 5, at this time port1=(5+12)%61+12345, thereby obtaining a new port number, the port corresponding to the port number is the target port, and the target port is immediately opened, that is, the target port is operated to receive new connections.

[0056] The communication port switching method provided by the embodiment of the present invention can enter a switching ready state when a target port function is received, and when a function switching instruction is received, the first end can communicate with the second end based on the target port determined by the target port function, so that the first end and the second end determine the same target port based on the same target port function, and there is no need to synchronize the ports between the first end and the second end, thereby significantly improving the security and reliability of the communication port and effectively reducing the probability of data transmission failure.

[0057] In one embodiment, for the server, when "the current port function changes", or when "time changes (such as Monday becomes Tuesday), resulting in a change in the port calculated according to the current port function", a new target port needs to be used. At this time, the server will first immediately open the use of the new target port, that is, run the target port to receive new connections, and then determine the way to close the current port according to whether the current port still has data connection or data transmission, specifically:

[0058] (a1) If the first end is transmitting data with the second end through the current port, a pre-close signal is sent to the second end, so that the second end interrupts the data transmission based on the pre-close signal. For example, the pre-close signal can be "I am about to close this port", expecting the client to actively try to interrupt the data transmission.

[0059] (a2) If the second end is detected to interrupt data transmission within the second preset time period, the current port is controlled to be closed; or, if the second end is not detected to interrupt data transmission within the second preset time period, the current port is controlled to be closed. For example, assuming that the second preset time period is 10 minutes, if the client is detected to interrupt data transmission within 10 minutes, the server can directly close the current port; if the client still does not interrupt data transmission after 10 minutes, the server will forcibly close the current port.

[0060] Based on the above embodiments, the present invention provides another communication port switching method, which is applied to the second end. Figure 3 FIG. 1 is a flow chart of another method for switching a communication port, the method mainly comprising the following steps S302 to S304:

[0061] Step S302, receiving the target port function, and controlling the second end to be in a switch-ready state. The target port function is used to determine the target port, and the switch-ready state is a state in which the target port can be run. In one embodiment, if the client receives the target port function, it will send a second response instruction to the port management server within a first preset time length, and enter the switch-ready state, and the client will temporarily store the target port function.

[0062] Step S304, receiving a function switching instruction, and controlling the second end to communicate with the first end through the target port; wherein the first end receives the target port function and is in a switching ready state. In one embodiment, a time parameter can be determined according to a port switching cycle matched by the target port function, and then the target port is determined according to the time parameter by the target port function, thereby controlling the second end to communicate with the first end through the target port. For details, please refer to the aforementioned step S204, which will not be described in detail in the embodiment of the present invention.

[0063] The communication port switching method provided by the embodiment of the present invention can enter a switching ready state when a target port function is received, and when a function switching instruction is received, the second end can communicate with the first end based on the target port determined by the target port function, so that the first end and the second end determine the same target port based on the same target port function, and there is no need to synchronize the ports between the first end and the second end, thereby significantly improving the security and reliability of the communication port and effectively reducing the probability of data transmission failure.

[0064] In actual applications, if the second end transmits data with the first end through the current port, and receives a pre-close signal sent by the first end, the data transmission is interrupted based on the pre-close signal, and the data transmission is resumed according to the target port. Exemplarily, when the client receives the message "I am about to close this port" sent by the server, the client attempts to interrupt the data transmission, recalculates the target port according to the "target port function" and the "current time", establishes a connection with the server on the target port, and resumes the data transmission. Specifically, when the client attempts to interrupt the data transmission, it can lock / suspend the data transmission thread, and calculate the target port according to the "target port function" and the "current time", so as to establish a connection with the server according to the target port. The data transmission thread reuses the connection. At this time, the client can resume the data transmission by unlocking / resuming the data transmission thread.

[0065] In one implementation, if the client cannot re-establish a connection with the server, an error prompt or an error log may be generated, such as generating a related email and sending the email to an associated terminal of the user.

[0066] In another implementation, if the port management server crashes, the server and the client can still use the current port function to calculate the target port number.

[0067] In another embodiment, if the user receives an email alert and finds after inspection that the target ports determined by the server and the client are always unequal, the user can: (1) check whether the system time difference between the server and the client is too large; (2) manually request the port management server to regenerate the target port function and send it to the server and the client.

[0068] To facilitate understanding of the above embodiments, an embodiment of the present invention provides an application example of a method for switching a communication port, see Figure 4 FIG. 4 is a flow chart of another method for switching a communication port, the method mainly comprising the following steps S402 to S426:

[0069] Step S402, Mgr periodically switches the target port function.

[0070] Step S404, Mgr sends the target port function to Ser.

[0071] Step S406, Mgr sends the target port function to Cli.

[0072] Step S408, Mgr waits for Ser and Cli to feedback a response instruction.

[0073] Step S410, Mgr sends function switching instructions to Ser and Cli respectively.

[0074] Step S412, Cli uses the target port function as the "current port function".

[0075] Step S414, Cli opens the target port according to the "current port function" and the "current time".

[0076] Step S416, Ser takes the target port function as the "current port function".

[0077] Step S418, Ser opens the target port according to the "current port function" and the "current time".

[0078] Step S420, Ser opens the target port and determines whether there is data transmission on the current port. If yes, execute step S424; if not, execute step S422.

[0079] Step S422, Ser closes the current port.

[0080] Step S424, requiring the Cli to actively close the current port, otherwise the current port is forcibly closed after a second preset time period.

[0081] Step S426, when Cli receives Ser's request to close the current port, it attempts to stop data transmission and attempts to resume data transmission according to the "current port function" and the "current time".

[0082] For the communication port switching method provided in the above embodiment, the present invention provides a communication port switching device, which is applied to a port management server, see Figure 5 The structure diagram of a switching device of a communication port shown in FIG. 1 mainly includes the following parts:

[0084] The instruction sending module 504 is used to send function switching instructions to the first end and the second end respectively when it is monitored that both the first end and the second end are in a switching ready state, so that the first end and the second end communicate based on the target port function; wherein the switching ready state is a state in which the target port can be operated.

[0085] The switching device of the communication port provided by the embodiment of the present invention can send a function switching instruction to the first end and the second end when it monitors that the first end and the second end are in a switching ready state, so that the first end and the second end can determine the same target port for communication based on the same target port function, without the need for port synchronization between the first end and the second end, thereby significantly improving the security and reliability of the communication port and effectively reducing the probability of data transmission failure.
