Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a communication method, device, storage medium and program product. Background Art

[0002] Customer premises equipment (CPE), a type of home gateway, interacts directly with clients through service ports, providing them with various network services. Each service port corresponds to a specific service. For example, Hypertext Transfer Protocol (HTTP) port 80 provides web browsing services for clients, while Hypertext Transfer Protocol Secure (HTTPS) port 443 provides encrypted web browsing services.

[0003] However, the more service ports a CPE exposes, the greater its potential attack surface, leading to higher network security risks. Therefore, how to reduce the network security risks of CPE is an unresolved issue. Summary of the Invention

[0004] The embodiments of the present application provide a communication method, device, storage medium, and program product that can reduce network security risks of CPE.

[0005] In a first aspect, embodiments of the present application provide a communication method. The method includes: a CPE receiving first information from a client via a first port, the first information including a port number of a second port, the second port being the source port of the first information. If the port number of the second port is the same as the port number agreed upon between the CPE and the client, the CPE determines that one or more internal service ports of the CPE provide services to the client; if the port number of the second port is different from the port number agreed upon between the CPE and the client, the CPE determines that the first port provides services to the client.

[0006] It can be seen that in the embodiment of the present application, when the source port number of the first information (i.e., the port number of the second port) is the same as the port number agreed upon by the CPE and the client, the CPE determines that the internal service port of the CPE provides services to the client, which is conducive to the CPE forwarding the received information to the internal service port through the first port to achieve indirect interaction between the second port and the internal service port. Compared with the method of directly exposing multiple service ports by the CPE, the network security risk of the CPE can be reduced.

[0007] In addition, in an embodiment of the present application, the CPE can determine that the first port provides services to the client when the source port number of the first information (i.e., the port number of the second port) is different from the port number agreed upon by the CPE and the client, which is conducive to the CPE realizing multi-service carrying to meet different service requests of the client.

[0008] Optionally, ports provide services to clients, which can be understood as providing the required network services to clients through ports. For example, HTTP port 80 (referred to as port 80) provides web browsing services for clients, HTTPS port 443 (referred to as port 443) provides encrypted web browsing services for clients, Secure Shell (SSH) port 22 (referred to as port 22) provides remote server login or management services for clients, and File Transfer Protocol (FTP) port 21 (referred to as port 21) provides file upload and download services for clients.

[0009] In an optional implementation manner, the first information is used to request the CPE to establish a connection, that is, the first information may be request information for requesting the CPE to establish a connection.

[0010] In the above implementation, the CPE can determine whether the port number of the second port is the port number agreed upon by the CPE and the client based on the port number of the second port during the connection establishment phase with the client, so as to determine the port for providing services to the client, thereby facilitating the CPE to provide various services to the client based on the determined port.

[0011] In an optional embodiment, when the port number of the second port is the same as the port number agreed upon by the CPE and the client, the CPE may also perform the following operations: receiving first data from the client through the first port, the first data including first identification information for identifying the first data; determining a third port based on the first identification information, the third port being one of one or more internal service ports; and sending the first data to the third port through the first port.

[0012] In this embodiment, when the port number of the second port is the same as the port number agreed upon by the CPE and the client, the CPE receives the first data from the second port through the first port, and can further determine the target port (i.e., the third port) of the first data based on the first identification information, so that the first port forwards the first data to the third port, thereby facilitating the third port to provide services to the client.

[0013] In an optional implementation manner, the CPE may further perform the following operations: providing services to the client according to the third port and the first data.

[0014] In an optional implementation, when the second port number is different from the port number agreed upon by the CPE and the client, the CPE may also perform the following operations: receive second data from the client through the first port; and provide services to the client based on the first port and the second data.

[0015] In this embodiment, when the port number of the second port of the CPE is different from the port number agreed upon by the CPE and the client, the first port receives the second data from the second port and provides services to the client based on the first port and the second data. In this way, the first port can also provide services to the client to meet the client's service request.

[0016] In a second aspect, an embodiment of the present application provides a communication device, the device comprising: A communication module, configured to receive first information from a client, wherein the first information includes a port number of a second port, and the second port is a source port of the first information; a processing module, configured to, when the port number of the second port is the same as the port number agreed upon by the CPE and the client, determine that one or more internal service ports of the CPE provide services to the client; The processing module is further configured to determine that the first port provides services for the client when the port number of the second port is different from the port number agreed upon by the CPE and the client.

[0017] In addition, in this aspect, other optional implementations of the communication device can refer to the relevant content of the first aspect above and will not be described in detail here.

[0018] In a third aspect, an embodiment of the present application provides a communication device, comprising a communication module, a power module, a storage module, and a chip, wherein: The power supply module is used to provide power to the communication device; The storage module is used to store data and instructions; The communication module is used for internal communication of the communication device, or for communication between the communication device and an external device; The chip is used to execute the method described in the first aspect above.

[0019] In a fourth aspect, the present application further provides a computer device, comprising: a memory and a processor, wherein a computer program is stored in the memory, and when the computer program is executed by the processor, the steps of the above method are implemented.

[0020] In a fifth aspect, the present application further provides a computer storage medium, wherein the computer storage medium stores a computer program, and when the computer program is executed by a processor, the steps of the above method are implemented. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application.

[0028] In the subsequent description, the use of suffixes such as "module", "component" or "unit" to represent elements is only for the purpose of facilitating the description of the present application and has no specific meaning. Therefore, "module", "component" or "unit" can be used interchangeably.

[0029] In order to better understand the communication method disclosed in the embodiment of the present application, the system architecture applicable to the embodiment of the present application is described.

[0030] Figure 1 This is a schematic diagram of the architecture of a communication system provided in an embodiment of the present application. Figure 1 As shown, the communication system includes a client 101 and customer premises equipment (CPE) 102. The client 101 is used to initiate a request to the CPE and receive a response. The CPE 102, as a home gateway device, is used to receive the client's request and return a response.

[0031] The client in the embodiments of the present application may be a terminal device that communicates with the CPE. The terminal device may also be referred to as a terminal, and may refer to various forms of user equipment (UE), access terminal, remote terminal, mobile device, personal computer (PC), user terminal, wireless communication device, user agent, or user device. The terminal device may also be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, a terminal device in a fifth-generation mobile communication (5G) network, or a terminal device in a future-evolved public land mobile network (PLMN), etc., and the embodiments of the present application are not limited thereto.

[0032] The CPE in the embodiments of this application can be any device deployed on the user side to access the operator's network and provide various network services. The CPE can be a wireless router, a fourth-generation mobile communication (4G) CPE, a 5G CPE, a smart home gateway, etc., and the embodiments of this application are not limited to these.

[0033] In one approach, the CPE's multiple service ports interact directly with the client, providing it with various network services. However, the more service ports the CPE exposes, the greater its potential attack surface, posing a higher network security risk.

[0034] This application embodiment proposes a communication method, which is described from the perspective of CPE. Figure 2 , Figure 2 This is a flow chart of a communication method provided in an embodiment of the present application, which includes but is not limited to: S201. The CPE receives first information from the client through the first port.

[0035] The first port is a port directly exposed to the outside on the CPE, for example, the first port is a port directly exposed to the client on the CPE, and is used for direct interaction with the client. For example, the first port may be port 80.

[0036] The first information includes the port number of the second port, which is the source port of the first information. This helps the CPE determine whether the source port number of the first information (i.e., the port number of the second port) is the same as the port number agreed upon between the CPE and the client. This in turn helps the CPE determine the port providing services to the client and provide the required services to the client based on the determined port.

[0037] In a possible implementation, the CPE checks the port number of the second port.

[0038] Optionally, the CPE verifies the port number of the second port, including: verifying whether the port number of the second port is the same as the port number agreed upon between the CPE and the client. For example, if the port number agreed upon between the CPE and the client is 1024 and the port number of the second port is 1024, then the port number of the second port is the same as the port number agreed upon between the CPE and the client. For another example, if the port number agreed upon between the CPE and the client is 1024 and the port number of the second port is 1022, then the port number of the second port is different from the port number agreed upon between the CPE and the client.

[0039] The CPE and the client may agree on the port number before the client sends the first information, which is not limited in this embodiment of the present application.

[0040] In one possible implementation, the first information is used to request the CPE to establish a connection. That is, the first information may be request information for requesting the CPE to establish a connection. This approach facilitates the CPE, during the connection establishment phase with the client, to determine, based on the port number of the second port, whether the port number of the second port is the same as the port number agreed upon between the CPE and the client, thereby determining the port to provide services to the client. This facilitates the CPE to provide various services to the client based on the determined port.

[0041] S202. When the port number of the second port is the same as the port number agreed upon between the CPE and the client, the CPE determines that one or more internal service ports of the CPE provide services for the client.

[0042] The internal service port is a port on the CPE that is not directly exposed to the outside world. For example, the internal service port is a port on the CPE that is not directly exposed to the client. The internal service port can indirectly interact with the client through the first port. For example, the internal service port can be one or more of port 443, port 22, and port 21.

[0043] Optionally, one or more internal service ports of the CPE provide services to the client, which can be understood as: one or more internal service ports of the CPE provide the client with the required network services. Assuming that the internal service ports include port 443, port 22, and port 21, the CPE can provide encrypted web browsing services to the client through port 443, provide remote login to a server or management server through port 22, and provide file upload and download services to the client through port 21. The services provided to the client by ports 443, 22, and 21 are not limited to the above, and are not limited to these in the embodiments of the present application.

[0044] S203. When the port number of the second port is different from the port number agreed upon between the CPE and the client, the CPE determines that the first port provides services for the client.

[0045] Optionally, providing services to the client through the first port can be understood as providing the client with the required network services through the first port. Assuming the first port is port 80, the CPE can provide web browsing services to the client through port 80. The services provided to the client through port 80 are not limited to the above, and are not limited in this embodiment of the present application.

[0046] It can be seen that in the embodiment of the present application, the CPE can determine that the internal service port of the CPE provides services to the client when the source port number of the first information (i.e., the port number of the second port) is the same as the port number agreed upon by the CPE and the client, thereby facilitating the CPE to forward the received information to the internal service port through the first port to achieve indirect interaction between the second port and the internal service port. Compared with directly exposing multiple service ports, the network security risk of the CPE can be reduced.

[0047] In addition, in an embodiment of the present application, the CPE can determine that the first port provides services to the client when the source port number of the first information (i.e., the port number of the second port) is different from the port number agreed upon by the CPE and the client, which is conducive to the CPE realizing multi-service carrying to meet different service requests of the client.

[0048] See also Figure 3 , Figure 3 A flow chart of another communication method provided in an embodiment of the present application, which includes but is not limited to: S301. The client sends the first information.

[0049] Correspondingly, the CPE receives the first information through the first port.

[0050] The relevant contents of S301 can be found in the relevant description of S201 above, which will not be repeated here.

[0051] S302. The CPE verifies the port number of the second port.

[0052] The relevant contents of S302 can be found in the relevant description of S201 and will not be repeated here.

[0053] The CPE verifies the port number of the second port in the following situations: Case 1: The port number of the second port is the same as the port number agreed upon by the CPE and the client. Execute S303 to S308 below: S303. When the port number of the second port is the same as the port number agreed upon between the CPE and the client, the CPE determines that one or more internal service ports of the CPE provide services for the client.

[0054] The relevant contents of S303 can be found in the relevant description of S202 above, which will not be repeated here.

[0055] S304. The CPE sends information indicating that the verification is complete.

[0056] The information indicating that the verification is completed means that the CPE device has completed the verification between the port number of the second port and the port number agreed upon by the CPE and the client.

[0057] Accordingly, the client receives information indicating that the verification is complete, which facilitates the client to send data to the CPE based on the information to obtain services.

[0058] S305. The client sends the first data through the second port.

[0059] Correspondingly, the CPE receives the first data through the first port.

[0060] Optionally, the first data may be service request data from the client, that is, service request data sent by the client to the CPE. For example, the first data may be service request data requesting the CPE to enable the service corresponding to port 443. For another example, the first data may be service request data requesting the CPE to enable the service corresponding to port 22. For another example, the first data may be service request data requesting the CPE to enable the service corresponding to port 21. In this way, the CPE can parse the service request data and provide the required service to the client.

[0061] The first data includes first identification information for identifying the first data, and the first identification information is used to distinguish the type of the first data. For example, the CPE can distinguish whether the first data is https data, ssh data, or ftp data based on the first identification information.

[0062] It can be seen that when the port number of the second port is the same as the port number agreed upon by the CPE and the client, the CPE receives the first data from the second port through the first port, which is beneficial for the CPE to further determine the receiving port of the first data based on the first identification information, so that the CPE forwards the first data to the corresponding receiving port through the first port to provide services to the client.

[0063] S306. The CPE determines the third port according to the first identification information.

[0064] The third port is one of one or more internal service ports, and is used to indirectly interact with the client and provide services to the client.

[0065] For example, the CPE determines that the third port is port 443 among the one or more internal service ports based on the first identification information indicating that the first data is https data. For another example, the CPE determines that the third port is port 22 among the one or more internal service ports based on the first identification information indicating that the first data is ssh data. For another example, the CPE determines that the third port is port 21 among the one or more internal service ports based on the first identification information indicating that the first data is ftp data.

[0066] It can be seen that the CPE can determine the third port from one or more internal service ports according to the first identification information, which is conducive to the CPE accurately providing the required service to the client according to the third port.

[0067] S307. The CPE sends the first data to the third port through the first port.

[0068] Correspondingly, the CPE receives the first data from the first port through the third port.

[0069] It can be seen that the CPE forwards the first data to the third port through the first port, which is conducive to isolating the third port from the second port, thereby reducing the network security risk of the CPE.

[0070] S308. The CPE provides services to the client based on the third port and the first data.

[0071] Optionally, the CPE provides services to the client based on the third port and the first data, which can be understood as: the CPE parses the first data through the service program of the third port, and provides services to the client through the service program of the third port based on the parsing result.

[0072] For example, the CPE parses https data through the service program on port 443 and, based on the parsing results, provides web page transmission services to the client through the service program on port 443. Another example is that the CPE parses ssh data through the service program on port 22 and, based on the parsing results, provides remote server login or management services to the client through the service program on port 22. Another example is that the CPE parses ftp data through the service program on port 21 and, based on the parsing results, provides file upload and download services to the client through the service program on port 21.

[0073] It can be seen that in case one, when the port number of the second port is the same as the port number agreed upon by the CPE and the client, the CPE receives the first data from the second port through the first port, and can further determine the target port (i.e., the third port) of the first data based on the first identification information, so that the first port can forward the first data to the third port, and provide services to the client based on the third port and the first data to meet the client's service request.

[0074] Case 2: If the port number of the second port is different from the port number agreed upon by the CPE and the client, execute S309 to S312 below: S309. If the port number of the second port is different from the port number agreed upon between the CPE and the client, the CPE determines that the first port provides services to the client.

[0075] The relevant contents of S309 can be found in the relevant description of S203 above, which will not be repeated here.

[0076] S310. The CPE sends information indicating that verification is complete.

[0077] Accordingly, the client receives information indicating that the verification is complete.

[0078] The relevant contents of S310 can be found in the relevant description of S304 above, which will not be repeated here.

[0079] S311. The client sends the second data through the second port.

[0080] Correspondingly, the CPE receives the second data through the first port.

[0081] Optionally, the second data may be service request data from the client, i.e., service request data sent by the client to the CPE. For example, the second data may be service request data requesting the CPE to enable a service corresponding to port 80. In this way, the CPE can parse the service request data and provide the required service to the client.

[0082] It can be seen that when the port number of the second port of the CPE is different from the port number agreed upon by the CPE and the client, the first port receives the second data from the second port, which is beneficial for the CPE to provide services to the client based on the first port and the second data.

[0083] S312. The CPE provides services to the client according to the first port and the second data.

[0084] Optionally, the CPE provides services to the client based on the first port and the second data. This can be understood as: the CPE parses the second data through the service program on the first port, and based on the parsing result, provides services to the client through the service program on the first port. For example, the CPE parses HTTP data through the service program on port 80, and based on the parsing result, provides web browsing services to the client through the service program on port 80.

[0085] It can be seen that in case 2, when the port number of the second port of the CPE is different from the port number agreed upon by the CPE and the client, after receiving data through the first port, there is no need to distinguish the data, but the first port can directly parse the data and provide services to the client.

[0086] In addition, the CPE receives the second data from the second port through the first port and provides services to the client according to the first port and the second data. In this way, the first port can also provide services to the client to meet the service request of the client.

[0087] S313. The client sends information indicating disconnection.

[0088] Accordingly, the CPE receives information indicating disconnection.

[0089] Optionally, the client sends a disconnection instruction based on its own circumstances. For example, if the client detects high energy consumption, it sends a disconnection instruction to the CPE to disconnect. For another example, if the client detects insufficient memory resources, it sends a disconnection instruction to the CPE to disconnect.

[0090] It can be seen that in the embodiment of the present application, the CPE receives data from the client through the first port and sends data to the internal service port, which can realize indirect interaction between the second port and the internal service port. Compared with the method of directly exposing multiple service ports, the network security risk of the CPE can be reduced.
