[0038] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0039] The data packet processing method provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown. Among them, the client terminal device 102 communicates with the server 104 through the network. The data storage system can store the initial data packets that the server 104 needs to process. The data storage system can be integrated on the server 104, or it can be placed on the cloud or other network servers. Among them, the client terminal device 102 serves as a wireless access device, converts the wireless cellular signal into wireless LAN / LAN data, and provides data pipeline services. The server 104 can be implemented with an independent server or a server cluster consisting of multiple servers.
[0040] First of all, it should be noted that due to software quality issues or specific service changes, the CPE needs to use the Firmware Over-The-Air (FOTA) technology to upgrade the system to ensure normal use by users. The FOTA upgrade package consists of a header and an upgrade image, which is stored on the FOTA server. The CPE connects to the FOTA server through the network to download the upgrade package. Usually, the upgrade image is encrypted as a whole. After the CPE downloads the upgrade package, it needs to decrypt the upgrade image before upgrading. After the decryption is completed, the storage space contains both the encrypted image and the decrypted image. An upgrade image generally exceeds 100MB. Since the upgrade image is decrypted as a whole in the CPE, the storage space contains both the encrypted image and the decrypted image after the upgrade image is decrypted. The redundant space required by the CPE is at least 100MB, resulting in a waste of CPE storage resources and excessive occupation of CPE storage space.
[0041] In one embodiment, Figure 2 As shown, a data packet processing method is provided, which is applied to Figure 1 The client terminal device in the example is used as an example to illustrate, including the following steps:
[0042] S201, receiving a data packet sent by a server; the data packet includes a plurality of encrypted data blocks.
[0043] Among them, the data packet can be a data packet of any application in the customer terminal equipment (Customer Premise Equipment, CPE). As an optional implementation, the data packet in the embodiment of the present application can be an air download technology (Firmware Over-The-Air, FOTA) data packet.
[0044] Optionally, in this embodiment, the client terminal device may send a request to the server to obtain the data packet from the server when an upgrade is required; or, the server may periodically send the data packet to the client terminal device according to a preset sending cycle.
[0045] Optionally, the multiple encrypted data blocks included in the data packet in this embodiment can be obtained by the server dividing the initial data packet into multiple data blocks and then encrypting the divided multiple data blocks respectively. Optionally, in this embodiment, the data volume of each encrypted data block can be determined according to a preset threshold, that is, the server can divide the initial data packet into multiple data blocks according to the preset threshold, and then encrypt the divided multiple data blocks respectively to obtain the above-mentioned multiple encrypted data blocks.
[0046] S202, decrypting a plurality of encrypted data blocks in a preset order, and deleting a corresponding encrypted data block when the decryption of each encrypted data block is completed.
[0047] Optionally, in this embodiment, after the client terminal device receives a data packet including multiple encrypted data blocks sent by the server, the client terminal device can decrypt the multiple encrypted data blocks of the data packet in order from the beginning to the end of the data packet, and delete the corresponding encrypted data block when the decryption of each encrypted data block is completed, or, after the client terminal device receives a data packet including multiple encrypted data blocks sent by the server, the client terminal device can decrypt the multiple encrypted data blocks of the data packet in order from the end to the beginning of the data packet, and delete the corresponding encrypted data block when the decryption of each encrypted data block is completed.
[0048] For example, assuming that the data size of each encrypted data block is 10MB, you can start from the end of the encrypted image of the received data packet and decrypt it in units of 10MB. After each 10MB of data is decrypted, the decrypted encrypted data block is immediately deleted. The redundant space occupied in the client terminal device is 10MB. Compared with traditional technologies, the storage space occupied by the client terminal device is greatly reduced.
[0049] Optionally, in this embodiment, when decrypting multiple encrypted data blocks, the client terminal device may use a decryption algorithm that is symmetrical to the encryption algorithm of the encrypted data block to decrypt each encrypted data block.
[0050] In the above-mentioned data packet processing method, since the data packet sent by the server received by the client terminal device includes multiple encrypted data blocks, the client terminal device can decrypt the multiple encrypted data blocks separately according to a preset order, and delete the corresponding encrypted data block when the decryption of each encrypted data block is completed. In this way, during the upgrade of the client terminal device, only the storage space corresponding to each encrypted data block is redundantly occupied. Compared with the traditional technology that occupies the storage space corresponding to the entire data packet, this solution greatly reduces the storage space occupied by the client terminal device during the data packet decryption process, and avoids the problem of excessive occupation of the storage space of the client terminal device during the upgrade of the client terminal device.
[0051] In this embodiment, the detailed process of the client terminal device decrypting multiple encrypted data blocks in a preset order is described. In one embodiment, the multiple encrypted data blocks are arranged in sequence from the beginning to the end; the above S202 includes: step A, decrypting the multiple encrypted data blocks in order from the end to the beginning.
[0052] In this embodiment, after receiving the data packet, the client terminal device can decrypt the multiple encrypted data blocks in the received data packet in order from the end to the beginning. Accordingly, as an optional implementation, the above data packet can be obtained by the server grouping and encrypting the initial data packet in order from the end to the beginning. Optionally, in this embodiment, the data volume of each encrypted data block is related to the data volume of the available storage space of the client terminal device, that is, in this embodiment, the server can determine the grouping threshold for grouping the initial data packet according to the available storage space of the client terminal device, divide the initial data packet into multiple data blocks according to the grouping threshold, and then group and encrypt the divided multiple data blocks in order from the end to the beginning to obtain the above data packet.
[0053] It should be noted that the initial data packet generally includes a header and an upgrade image. When the initial data packet is encrypted, the upgrade image therein is mainly encrypted. For example, Figure 3 As shown, Figure 3 When making an encrypted upgrade image for a server, the image data is grouped in units of 10MB, and each group of data blocks in the initial data packet is encrypted in the order from the end to the beginning of the initial data packet. The encrypted data block size is consistent with the original data block size. After the upgrade image is encrypted, the header is added to form a complete upgrade package. Accordingly, Figure 4 As shown, Figure 4 The figure shows a process in which the client terminal device decrypts a plurality of encrypted data blocks in a received data packet in order from the end to the beginning to obtain a decrypted data block corresponding to each encrypted data block.
[0054] In this embodiment, the client terminal device decrypts multiple encrypted data blocks in the received data packet in order from the end to the beginning, which can ensure that each encrypted data block in the received data packet is decrypted in sequence, ensuring the integrity of the multiple encrypted data blocks in the data packet when decrypting, and preventing decryption omissions, thereby ensuring the integrity of the decrypted data blocks obtained.
[0055] When the server encrypts the multiple data blocks in the initial data packet, the encryption key may be used for encryption. As an optional implementation, when the client terminal device decrypts the multiple encrypted data blocks, the encryption key may be used for decrypting the multiple encrypted data blocks. Figure 5 As shown, the above step A includes:
[0056] S301, receiving the encryption key of the data packet sent by the server.
[0057] Optionally, in this embodiment, the server may use a symmetric encryption algorithm to encrypt multiple data blocks in the initial data packet. After encrypting the multiple data blocks of the initial data packet, the server may send an encryption key of the symmetric encryption algorithm to the client terminal device.
[0058] S302, decrypting multiple encrypted data blocks using the encryption key in order from the end to the beginning.
[0059] In this embodiment, after the client terminal device receives the encryption key of the above-mentioned data packet sent by the server, it can use the received encryption key to decrypt multiple encrypted data blocks in the data packet in order from the end to the beginning to obtain multiple decrypted data blocks corresponding to the data packet.
[0060] In this embodiment, the client terminal device can receive the encryption key corresponding to the data packet sent by the server, so that when decrypting multiple encrypted data blocks included in the data packet, the multiple encrypted data blocks in the data packet can be decrypted in order from the end to the beginning using the received encryption key, thereby ensuring the accuracy and integrity of the decryption of the encrypted data blocks, and obtaining the decrypted data blocks corresponding to each encrypted data block in the data packet completely and accurately.
[0061] In some scenarios, the client terminal device can also use the multiple decrypted data blocks obtained above to upgrade the client terminal device. Figure 6 As shown, the above method also includes:
[0062] S401, arranging and combining decrypted data blocks corresponding to a plurality of encrypted data blocks in a decryption order to obtain a decrypted data packet.
[0063] In this embodiment, after the client terminal device decrypts multiple encrypted data blocks in the data packet and obtains the decrypted data blocks corresponding to each encrypted data block, the decrypted data blocks corresponding to the multiple encrypted data blocks can be arranged and combined in the order of decryption, and the decrypted data blocks can be combined into a complete data packet to obtain the decrypted data packet. Optionally, the client terminal device can sequentially arrange and combine the decrypted data blocks corresponding to each encrypted data block in the order of decryption to obtain the above-mentioned decrypted data packet.
[0064] S402, upgrading the client terminal device using the decrypted data packet.
[0065] In this embodiment, after the client terminal device obtains the complete decrypted data packet, the client terminal device can be further upgraded and updated using the obtained complete decrypted data packet to update the software and services of the client terminal device.
[0066] In this embodiment, after the client terminal device arranges and combines the decrypted data blocks corresponding to the multiple encrypted data blocks in the data packet in the order of decryption, it can obtain a complete decrypted data packet, so that the client terminal device can be upgraded using the complete decrypted data packet, and the client terminal device can be updated and maintained in a timely manner, ensuring the availability of the client terminal device.
[0067] In one embodiment, Figure 7 As shown, a data packet processing method is provided, which is applied to Figure 1 The server in the example is used to illustrate the following steps:
[0068] S501, encrypting the initial data packet in groups in order from the end to the beginning to obtain a data packet including a plurality of encrypted data blocks.
[0069] Optionally, in the present embodiment, the data volume of each encrypted data block included in the data packet may be related to the data volume of the available storage space of the client terminal device, that is, in the present embodiment, the server may determine a grouping threshold for grouping the initial data packet based on the available storage space of the client terminal device, divide the initial data packet into multiple data blocks according to the grouping threshold, and then group and encrypt the multiple divided data blocks in order from the end to the beginning to obtain the above-mentioned data packet.
[0070] Optionally, in this embodiment, the server may use a symmetric encryption algorithm to encrypt multiple data blocks in the initial data packet. After encrypting the multiple data blocks of the initial data packet, the server may send the encryption key of the data packet to the client terminal device, so that the client terminal device can use the encryption key to decrypt the multiple encrypted data blocks in order from tail to head when decrypting the multiple encrypted data blocks in order from tail to head.
[0071] S502, sending a data packet to a client terminal device, so that the client terminal device decrypts a plurality of encrypted data blocks according to a preset order, and deletes the corresponding encrypted data block when the decryption of each encrypted data block is completed.
[0072] Among them, the data packet can be a data packet of any application in the customer terminal equipment (Customer Premise Equipment, CPE). As an optional implementation, the data packet in the embodiment of the present application can be an air download technology (Firmware Over-The-Air, FOTA) data packet.
[0073] Optionally, in this embodiment, when the client terminal device needs to be upgraded, the client terminal device sends an acquisition request to the server, and the server sends a data packet to the client terminal device based on the acquisition request; or, the server periodically sends data packets to the client terminal device according to a preset sending cycle.
[0074] Optionally, the multiple encrypted data blocks included in the data packet in this embodiment can be obtained by the server dividing the initial data packet into multiple data blocks and then encrypting the divided multiple data blocks respectively. Optionally, in this embodiment, the data volume of each encrypted data block can be determined by the server according to a preset threshold, that is, the server can divide the initial data packet into multiple data blocks according to the preset threshold, and then encrypt the divided multiple data blocks respectively to obtain the above-mentioned multiple encrypted data blocks.
[0075] Optionally, in this embodiment, after the client terminal device receives a data packet including multiple encrypted data blocks sent by the server, the client terminal device can decrypt the multiple encrypted data blocks of the data packet in order from the beginning to the end of the data packet, and delete the corresponding encrypted data block when the decryption of each encrypted data block is completed, or, after the client terminal device receives a data packet including multiple encrypted data blocks sent by the server, the client terminal device can decrypt the multiple encrypted data blocks of the data packet in order from the end to the beginning of the data packet, and delete the corresponding encrypted data block when the decryption of each encrypted data block is completed.
[0076] For example, assuming that the data size of each encrypted data block is 10MB, you can start from the end of the encrypted image of the received data packet and decrypt it in units of 10MB. After each 10MB of data is decrypted, the decrypted encrypted data block is immediately deleted. The redundant space occupied in the client terminal device is 10MB. Compared with traditional technologies, the storage space occupied by the client terminal device is greatly reduced.
[0077] Optionally, in this embodiment, when decrypting multiple encrypted data blocks, the client terminal device may use a decryption algorithm that is symmetrical to the encryption algorithm of the encrypted data block to decrypt each encrypted data block.
[0078] In the above-mentioned data packet processing method, since the data packet sent by the server to the client terminal device is a data packet including multiple encrypted data blocks obtained by the server grouping and encrypting the initial data packet in order from the end to the beginning, the client terminal device can decrypt the multiple encrypted data blocks respectively in a preset order after receiving the data packet, and delete the corresponding encrypted data block when the decryption of each encrypted data block is completed. In this way, during the upgrade process of the client terminal device, only the storage space corresponding to each encrypted data block is redundantly occupied. Compared with the traditional technology that occupies the storage space corresponding to the entire data packet, this scheme greatly reduces the storage space occupied by the client terminal device during the data packet decryption process, and avoids the problem of excessive occupation of the storage space of the client terminal device during the upgrade process of the client terminal device.
