[0041] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0042] Reference Figure 1 , Figure 1 This is one of the flow charts of the audio and video transmission method in the embodiment of the present application. The audio and video transmission method provided in the embodiment of the present application may include:

[0043] Step 100, when the signaling request sent by the target device passes the inspection, receiving the audio and video stream pushed by the target device;

[0044] Specifically, the audio and video transmission method in the embodiment of the present application includes three parts: signaling inspection, audio and video stream inspection, and the processing process of failed inspection. This embodiment focuses on the inspection of audio and video streams and the processing process of failed inspection, and the signaling inspection part will be described below. The inspection process of the audio and video stream is first to receive the audio and video stream pushed by the target device. In order to enhance the security of receiving the audio and video stream, the gateway service that receives the audio and video stream pushed by the target device allocates a stream receiving port for each signaling request sent by the target device (using a random allocation method), and only after the signaling request inspection is passed, the listening state of the stream receiving port is opened, that is, the audio and video stream pushed by the target device is received only after the signaling request inspection is passed.

[0045] Step 200, when the audio and video stream is a real-time transport protocol packet, parsing the real-time transport protocol packet;

[0046] The audio and video transmission method provided in the embodiment of the present application may further include:

[0047] Step 600, when the audio and video stream is not a real-time transport protocol packet, the source Internet Protocol address of the audio and video stream is added to a preset blacklist through a preset packet filtering firewall proxy module.

[0048] Specifically, after receiving the public network data (the audio and video stream pushed by the target device), the receiving port first detects whether the audio and video stream pushed by the target device is a normal Real-time Transport Protocol (RTP) packet. If the audio and video stream pushed by the target device is not an RTP packet, it is directly determined that the source Internet Protocol Address (IP) of the audio and video stream does not meet the requirements, that is, the audio and video stream inspection fails. The processing process of the audio and video stream that fails the inspection is as follows: the gateway service notifies the packet filtering firewall proxy module to add the source IP of the audio and video stream to the firewall of the operating system, and directly isolates the request source that does not meet the requirements at the network level, reducing the processing pressure of the gateway service.

[0049] After detecting that the audio and video stream pushed by the target device is a normal real-time transport protocol packet, the RTP payload type (RTP Payload Type, RTP PT) and SSRC (synchronization source identifier, length is 32 bits, the synchronization source refers to the source of the RTP packet stream) in the RTP packet are parsed out.

[0050] Step 300, comparing the parsing result with the signaling request to obtain a first comparison result;

[0051] The audio and video transmission method provided in the embodiment of the present application may further include:

[0052] Step 310, compare the first field in the parsing result with the second field in the second configuration response information to obtain a first comparison result; the first comparison result includes that the first field is consistent with the second field, and the first field is inconsistent with the second field.

[0053] Specifically, the RTP payload type and SSRC (i.e., the parsing result in this embodiment) parsed from the RTP packet are compared with the corresponding values ​​of the fields obtained during the inspection process of the first part of the signaling to determine whether the first field in the parsing result is consistent with the second field in the second configuration response information. If they are inconsistent, it is directly determined that the source Internet Protocol address of the audio and video stream does not meet the requirements, that is, the audio and video stream inspection fails. The processing process of the audio and video stream that fails the inspection is as described above.

[0054] Step 400, comparing the source Internet Protocol address of the signaling request with the source Internet Protocol address of the audio and video stream to obtain a second comparison result;

[0055] Specifically, the registration port of the gateway service is different from the port of the audio and video stream, but the IP of the target device is definitely the same, so the gateway service side can check whether the source IP of the audio and video stream is consistent with the signaling source of the current audio and video stream SSRC, that is, the second comparison result in this embodiment. If they are inconsistent, it can be determined that the audio and video stream source does not meet the requirements; parse the sequence parameter set (Sequence Paramater Set, SPS) and picture parameter set (Picture Paramater Set, PPS) before the first frame of the audio and video stream to obtain the encoding format, resolution and frame rate information in the video description information; parse the frames of the audio and video stream to obtain the encoding format and sampling rate information. The above parsed data is completely matched with the information stored in the field in the SDP. If inconsistency is found, it is directly determined that the audio and video stream source does not meet the requirements.

[0056] Step 500: Transmit the audio and video stream based on the first comparison result and the second comparison result.

[0057] The audio and video transmission method provided in the embodiment of the present application may further include:

[0058] Step 510, when the first comparison result is that the first field is consistent with the second field, and the second comparison result is that the source Internet Protocol address of the signaling request is consistent with the source Internet Protocol address of the audio and video stream, it is determined that the audio and video stream inspection has passed, and the audio and video stream is transmitted.

[0059] Specifically, according to the above content, it can be known that when the signaling request check passes, the audio and video stream is a real-time transport protocol packet, the first field in the parsing result is consistent with the second field in the second configuration response information, and the source Internet Protocol address of the signaling request and the source Internet Protocol address of the audio and video stream are consistent, if all are met, it is determined that the audio and video stream source meets the requirements. In this case, the audio and video stream that meets the requirements is transmitted.

[0060] This embodiment verifies the audio and video streams sent by the target device in strict accordance with the requirements of the GB / T28181 protocol, including verifying whether the audio and video streams are real-time transport protocol packets. The configuration parameters in the real-time transport protocol packet are parsed, and the parsing result is compared with the signaling request sent by the target device. The transmission of the audio and video stream is then processed securely in combination with the comparison result of the source Internet Protocol address of the signaling request and the source Internet Protocol address of the audio and video stream. This solves the risk of being vulnerable to injection attacks of media streams that do not meet the requirements based on the transmission of the public security video surveillance networking system.

[0061] Reference Figure 2 , Figure 2 This is a second flow chart of the audio and video transmission method in the embodiment of the present application. In one embodiment, the audio and video transmission method provided in the embodiment of the present application may also include:

[0062] Step 10, when the session initiation protocol request sent by the target device meets the preset requirements, sending the preset configuration information to the target device;

[0063] Specifically, regarding the inspection part of the above-mentioned signaling: in terms of signaling, whether the information content requested by the target device complies with the characteristics of the GB / T28181 protocol, such as whether the GBID (national standard unified code containing the regional code) meets the requirements, whether the registration cycle and heartbeat cycle of the target device comply with the customized configuration.

[0064] Configure unified GBID information (this part is generated strictly in accordance with the unified ID coding rules of the GB / T28181 protocol), customized registration expiration time, heartbeat sending cycle and heartbeat timeout times (for example, the default values ​​are 3600 seconds, 30 seconds and 3 times respectively) for the managed southbound security devices (i.e., the target devices in this embodiment). For example, they are set to 366 seconds (here, the validity period is greatly shortened to improve detection efficiency), 33 seconds and 4 times respectively, so that it is easy to judge whether it is a managed device that meets the requirements based on the registration and heartbeat rules. After configuration, the managed device will initiate registration with the southbound gateway deployed in the public network environment with no source restriction.

[0065] After receiving the SIP request for registration, the southbound gateway service first checks whether the GBID meets the requirements, mainly checking whether the ID length of the registration request field meets the number of digits of the GBID (for example, 20 digits). If not, the packet filtering firewall is directly notified to add it to the list and check whether the area code in the 20-digit GBID is in the same area as the requested IP. If the above information does not meet the requirements, the registered SIP request will be included in the suspect list, and then a manual review will be conducted. Enter the normal GB / T28181 protocol user ID and password verification process. If the password is incorrect, it is also considered to be unqualified and directly added to the blacklist.

[0066] Step 20, determining whether the session initiation protocol request passes the verification based on the first configuration response information of the target device;

[0067] The audio and video transmission method provided in the embodiment of the present application may further include:

[0068] Step 21: If the target device sends a registration request within the registration validity period, and the heartbeat of the target device is consistent with the heartbeat sending period, it is determined that the session initiation protocol request verification is passed.

[0069] Specifically, after the registration process check is passed, in order to ensure that the above customized configuration information is reviewed again, the customized registration expiration time, heartbeat sending cycle, heartbeat timeout times and other information are sent to the target device according to the commonly supported protocol. A simple check is performed on the above response information, and those that do not respond or respond abnormally can be directly added to the blacklist; enter the heartbeat cycle detection process, if the heartbeat of the target device is not sent according to the customized time period, it is also considered an illegal request and is directly added to the blacklist; enter the registration validity period detection process, if the cancellation and re-registration request of the target device is not received after the customized registration validity period, it is also considered an illegal request and is added to the blacklist; other response information of the target device (for example, subscription and alarm) is detected, and illegal responses are directly added to the blacklist and access is prohibited.

[0070] Step 30, when the session initiation protocol request verification passes, sending the target configuration information to the target device;

[0071] Step 40: Determine whether the signaling request of the target device passes the inspection based on the second configuration response information of the target device.

[0072] The audio and video transmission method provided in the embodiment of the present application may further include:

[0073] Step 41, determining the configuration information received by the target device, and information of the target device's response based on the received configuration information;

[0074] Step 42: Compare the received configuration information with the response information to determine whether the signaling request of the target device passes the inspection.

[0075] Specifically, the southbound gateway service generates a unique SSRC configuration and sends it to the target device signaling request SDP's y field, and determines whether the field in the received response SDP is consistent with the request field. If not, it is directly determined as a non-compliant response; next, the f field in the response SDP is parsed to determine whether the field is present or the audio and video format description information is strictly defined in accordance with the national standard. If the field exists but the description information is empty, the IP is included in the suspect list for manual review. The a field in the SDP records whether the RTP PT is within the range of 96-98 of the GB / T28181 protocol. If it exceeds this range, it is also considered a non-compliant request. The a, y, and f fields of the SDP in the above content and the corresponding southbound device IP address are saved for subsequent testing of whether the audio and video streams meet the requirements. If the information in the above content is incorrect, it does not completely violate the GB / T28181 protocol, so a manual review flow needs to be introduced.

[0076] This embodiment verifies the signaling request, determines that the request signaling does not meet the requirements, and directly adds the source IP to the firewall of the operating system, isolates the request source that does not meet the requirements at the network layer, and reduces the processing pressure of the southbound gateway service. It solves the risk of injection attacks on media streams that do not meet the requirements based on the transmission of public security video surveillance networking systems.
