[0050] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0051] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0052] The main solution of the embodiment of the present application is: obtain a marking block information set at a preset position in a pre-built encrypted upgrade package; decrypt the upgrade firmware at the corresponding position in the encrypted upgrade package based on the position information and encryption length in the marking block information set to obtain the decrypted upgrade firmware; and perform firmware upgrade based on the decrypted upgrade firmware.

[0053] In this embodiment, for the convenience of description, the firmware upgrade system is used as the execution subject for explanation below.

[0054] Since the current upgrade firmware is large in size, usually between 2GB and 7GB, and one upgrade package contains multiple firmwares that need to be upgraded, if these firmwares are packaged using a compression algorithm and the compressed upgrade package is encrypted using a traditional symmetric encryption algorithm, it will take too long to decrypt on the embedded device, thereby increasing the waiting time for firmware upgrades.

[0055] The present application provides a solution, which obtains a marker block information set at a preset position in a pre-built encrypted upgrade package, decrypts the upgrade firmware at the corresponding position in the encrypted upgrade package based on the position information and encryption length in the marker block information set, obtains the decrypted upgrade firmware, and performs firmware upgrade based on the decrypted upgrade firmware, so that the firmware can be directly obtained for upgrading without decompressing the upgrade package, and the upgrade firmware at the corresponding position in the encrypted upgrade package is decrypted based on the position information and encryption length in the marker block information set, thereby shortening the decryption time and reducing the waiting time for firmware upgrade.

[0056] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a firmware upgrade device, etc., or an electronic system capable of realizing the above functions, a firmware upgrade system, etc. The following takes the firmware upgrade system as an example to illustrate this embodiment and the following embodiments.

[0057] Based on this, the present application embodiment provides a firmware upgrade method, referring to Figure 1 , Figure 1 A flowchart of the first embodiment of the firmware upgrade method of the present application is provided.

[0058] In this embodiment, the firmware upgrade method includes steps S120, S140, and S150:

[0059] Step S120, obtaining a set of marking block information at a preset position in a pre-built encrypted upgrade package;

[0060] It should be noted that in a scenario where a firmware upgrade is required, a pre-built encrypted upgrade package is obtained.

[0061] Among them, a marking block information set exists at a preset position of the pre-built encrypted upgrade package.

[0062] The marker block information set refers to a series of data blocks or information sets located at specific preset positions in the pre-built encrypted upgrade package. These marker blocks contain important information about the encrypted firmware and are used to guide the subsequent decryption and firmware upgrade process.

[0063] As an implementation method, a marker block information set exists at the beginning / end of the pre-built encrypted upgrade package.

[0064] Before step S120, an encrypted upgrade package may be constructed first. As an implementation method, the method for constructing the encrypted upgrade package may include the following steps (1) to (4):

[0065] (1) using a high-performance compression algorithm (such as the LZ4 algorithm) to compress each upgrade firmware; using a file system image to encapsulate all compressed upgrade firmware to obtain an upgrade image;

[0066] (2) By parsing the file system layout, locate the location of the upgrade firmware in the upgrade image, and encrypt the dictionary (depending on the specific algorithm, some algorithms use hash tables, collectively referred to as dictionary tables) of the location according to the characteristics of the compression algorithm, and record the location information and encryption length as the encryption mark block information (ENC_INFO) for subsequent use;

[0067] (3) Continue parsing the file system until all firmware is encrypted and a series of encrypted mark block information is obtained; encrypt the key partition information, file distribution information, etc. of the file system, and also record and save the location and encryption length as encrypted mark block information;

[0068] (4) All the generated encrypted mark block information is encrypted and then saved at the end of the upgrade image. The new upgrade image is used as the encrypted upgrade package, and the encrypted upgrade package is thus completed.

[0069] Step S140, decrypting the upgrade firmware at the corresponding position in the encrypted upgrade package based on the position information and the encryption length in the marking block information set to obtain the decrypted upgrade firmware;

[0070] Among them, using the location information and encryption length provided in the marker block information set, the system can locate the encrypted firmware at the corresponding position in the encrypted upgrade package. Then, the system will decrypt the encrypted firmware using the same encryption algorithm and key (or key generation method) as when encrypting.

[0071] Step S150: performing firmware upgrade based on the decrypted upgrade firmware.

[0072] The image file containing the upgraded firmware can be mounted to the system so as to extract the firmware therefrom and perform the upgrade operation.

[0073] It should be noted that "mount" is a computer science term, which is usually used to connect a storage device (such as a hard disk partition, optical disc, USB device, etc.) or a part of a file system to the file system tree (also called a directory tree) of the operating system, so that users can access the contents of these devices or file systems just like accessing local files.

[0074] The present embodiment provides a firmware upgrade method, which obtains a marker block information set at a preset position in a pre-constructed encrypted upgrade package, decrypts the upgrade firmware at the corresponding position in the encrypted upgrade package based on the position information and encryption length in the marker block information set, obtains the decrypted upgrade firmware, and performs firmware upgrade based on the decrypted upgrade firmware, so that the firmware can be directly obtained for upgrading without decompressing the upgrade package, and the upgrade firmware at the corresponding position in the encrypted upgrade package is decrypted based on the position information and encryption length in the marker block information set, thereby shortening the decryption time and reducing the waiting time for firmware upgrade.

[0075] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the first embodiment can be referred to the above description, and will not be described in detail later. On this basis, in step S140, the upgrade firmware at the corresponding position in the encrypted upgrade package is decrypted based on the position information and the encryption length in the marker block information set, and before obtaining the decrypted upgrade firmware, the firmware upgrade method further includes step S130:

[0076] Step S130, decrypting the marker block information set to obtain a decrypted marker block information set;

[0077] The marker block information set may be decrypted using an appropriate decryption algorithm and key, such as a symmetric decryption algorithm, an asymmetric decryption algorithm, and the like.

[0078] The step S140, decrypting the upgrade firmware at the corresponding position in the encrypted upgrade package based on the position information and the encryption length in the marker block information set, and obtaining the decrypted upgrade firmware includes step S141:

[0079] Step S141, decrypting the upgrade firmware at the corresponding position in the encrypted upgrade package based on the position information and the encryption length in the decrypted mark block information set to obtain the decrypted upgrade firmware.

[0080] Among them, using the location information and encryption length provided in the marker block information set, the system can locate the encrypted firmware at the corresponding position in the encrypted upgrade package. Then, the system will decrypt the encrypted firmware using the same encryption algorithm and key (or key generation method) as when encrypting.

[0081] The present embodiment provides a firmware upgrade method, which obtains a marker block information set at a preset position in a pre-constructed encrypted upgrade package, decrypts the upgrade firmware at the corresponding position in the encrypted upgrade package based on the position information and encryption length in the marker block information set, obtains the decrypted upgrade firmware, and performs firmware upgrade based on the decrypted upgrade firmware, so that the firmware can be directly obtained for upgrading without decompressing the upgrade package, and the upgrade firmware at the corresponding position in the encrypted upgrade package is decrypted based on the position information and encryption length in the marker block information set, thereby shortening the decryption time and reducing the waiting time for firmware upgrade.

[0082] Based on the second embodiment of the present application, in the third embodiment of the present application, the same or similar contents as those in the second embodiment can be referred to the above description, and will not be described in detail later. On this basis, before step S120, obtaining the marker block information set at the preset position in the pre-built encrypted upgrade package, the firmware upgrade method further includes steps S10 to S60, S90 to S110:

[0083] Step S10, obtaining the upgrade firmware and the file system where the upgrade firmware is located;

[0084] Among them, the file system is a structure in the operating system for organizing and storing files and data. Different devices or operating systems may use different file systems.

[0085] Step S20, compressing the upgrade firmware using a preset compression algorithm to obtain compressed upgrade firmware;

[0086] Among them, in order to reduce the size of the upgraded firmware and improve its transmission efficiency, this step uses a preset compression algorithm (such as ZIP, GZIP, TAR, LZ4, etc.) to compress the firmware. The compressed firmware file will take up less storage space and may be completed faster in network transmission.

[0087] Step S30, encapsulating the compressed upgrade firmware through a file system image to obtain an upgrade image;

[0088] The file system image is a file that contains the complete file system structure, which simulates the file system layout on the actual storage device. The packaging process ensures that the firmware file can be correctly identified, decompressed and installed on the target device.

[0089] Step S40, parsing the file system layout, and locating the position of the upgrade firmware in the upgrade image;

[0090] After the encapsulation is completed, this step parses the file system layout in the upgrade image to determine the exact location of the compressed firmware file in the image. This usually involves reading the metadata or header information of the image file to obtain the file system structure and file storage location.

[0091] Step S50, encrypting the dictionary table in the position to obtain encrypted data;

[0092] In the firmware compression process, a data structure called a dictionary table is usually used to store recurring strings or data blocks to improve compression efficiency. This step encrypts the dictionary table part located in the firmware compressed data to increase the security of the firmware data and prevent unauthorized access or tampering.

[0093] Step S60, recording the relevant information of the position and the encryption length of the encrypted data as first encryption mark block information;

[0094] In order to accurately find and decrypt the encrypted firmware data during the decryption process, this step records the location information of the encrypted data (such as the starting offset and the ending offset) and the encryption length. This information is organized into one or more encrypted marker block information (herein referred to as the first encrypted marker block information) for subsequent use.

[0095] Step S90, encrypting the first encrypted marker block information to obtain the marker block information set;

[0096] In order to further improve security, the first encrypted mark block information may be encrypted.

[0097] Step S100, saving the marking block information set to a preset position in the upgrade image to obtain a new upgrade image;

[0098] As an implementation mode, the marker block information set may be saved to the head end / end of the upgrade image to obtain a new upgrade image.

[0099] Step S110: using the new upgrade image as the encrypted upgrade package.

[0100] This embodiment provides a firmware upgrade method, which records key information such as the location and encryption length of encrypted data through a marker block information set, which is crucial for the subsequent decryption process. By encrypting the marker block information set and saving it in a preset position in the upgrade image, the security of this information during transmission and storage is ensured, thereby improving the reliability of the firmware upgrade.

[0101] Based on the third embodiment of the present application, in the fourth embodiment of the present application, the same or similar contents as those in the third embodiment can be referred to the above description, and will not be described in detail later. On this basis, in step S90, before encrypting the first encrypted marking block information to obtain the marking block information set, the firmware upgrade method further includes steps S70 to S80:

[0102] Step S70, encrypting the metadata of the file system to obtain encrypted metadata;

[0103] Among them, metadata is information that describes the structure and content of the file system, such as file name, file size, file location, file permissions, etc.

[0104] As an implementation method, key file system partition information, file distribution information and other contents in the file system may be encrypted to obtain encrypted metadata.

[0105] Step S80, recording the metadata location information and the encrypted length of the encrypted metadata as second encrypted mark block information;

[0106] After encrypting the metadata, this step records the location information (such as the start offset and end offset) and the encryption length of the encrypted metadata in the file system image. This information is organized into the second encryption mark block information so that the encrypted metadata can be accurately found and decrypted during the decryption process.

[0107] The step S90 of encrypting the first encrypted marker block information to obtain the marker block information set includes the step S91:

[0108] Step S91, encrypting the first encrypted marker block information and the second encrypted marker block information to obtain the marker block information set.

[0109] Among them, this step combines the previously recorded first encrypted mark block information (about the location and encryption length of the encrypted firmware data) and the second encrypted mark block information (about the location and encryption length of the encrypted metadata), and encrypts the combined information. The encrypted mark block information set contains complete information about the encrypted firmware data and the encrypted metadata. The encrypted mark block information set ensures the security of this information during transmission and storage.

[0110] This embodiment provides a firmware upgrade method, which helps to accurately find and decrypt the encrypted metadata during the decryption process by recording the location information and encryption length of the encrypted metadata as the second encryption mark block information. This enhances the recoverability of the file system image, so that the file system structure and content can be completely restored when needed.

[0111] Based on the third embodiment of the present application, in the fifth embodiment of the present application, the same or similar contents as those in the third embodiment can be referred to the above description, and will not be described in detail later. On this basis, the file system is a FAT32 file system, and step S50, encrypting the dictionary table in the position, and obtaining the encrypted data also includes step S51:

[0112] Step S51, encrypting the FAT table information in the position to obtain the encrypted data.

[0113] This embodiment takes the FAT32 file system as an example. Figure 2 As shown, Figure 2 This is a schematic diagram of the FAT32 file system structure;

[0114] Among them, the structure of the FAT32 file system generally includes a boot area, a FAT table and a data area.

[0115] In order to achieve the confidentiality of the file system, some key parts of the FAT32 file system can be encrypted. As an implementation method, the boot area and the FAT table can be encrypted:

[0116] (1) Encrypting the boot area: By encrypting the boot area, unauthorized access or tampering can be prevented. If the boot area is encrypted, any device or software that attempts to access the file system without the correct decryption key will not be able to recognize or access the file system.

[0117] (2) FAT table encryption: The FAT table contains the storage location and link information of the file. By encrypting the FAT table, the contents of the file system can be further protected. Without the correct decryption key, the attacker will not be able to obtain the storage location of the file, and thus cannot read or tamper with the file content.

[0118] In this embodiment, each upgrade firmware is first compressed using a high-performance compression algorithm (such as the LZ4 algorithm); all compressed upgrade firmware are encapsulated using a file system image to obtain an upgrade image;

[0119] Then, by parsing the file system layout, that is, the FAT32 file system layout, the location of the upgrade firmware in the upgrade image is located, and according to the characteristics of the compression algorithm, the dictionary (depending on the specific algorithm, some algorithms use hash tables, collectively referred to as dictionary tables) of the location is encrypted, and the location information and the encryption length are recorded as the encryption mark block information (ENC_INFO) for subsequent use;

[0120] Then, the file system is parsed continuously until all firmware is encrypted and a series of encrypted mark block information is obtained; the key partition information and file distribution information of the file system are encrypted, and the location and encryption length are also recorded and saved as encrypted mark block information;

[0121] Finally, all the generated encrypted mark block information is encrypted and then saved at the end of the upgrade image. The new upgrade image is used as an encrypted upgrade package, and thus the encrypted upgrade package is completed.

[0122] The present embodiment provides a firmware upgrade method, which obtains a marker block information set at a preset position in a pre-constructed encrypted upgrade package, decrypts the upgrade firmware at the corresponding position in the encrypted upgrade package based on the position information and encryption length in the marker block information set, obtains the decrypted upgrade firmware, and performs firmware upgrade based on the decrypted upgrade firmware, so that the firmware can be directly obtained for upgrading without decompressing the upgrade package, and the upgrade firmware at the corresponding position in the encrypted upgrade package is decrypted based on the position information and encryption length in the marker block information set, thereby shortening the decryption time and reducing the waiting time for firmware upgrade.

[0123] Based on the third embodiment of the present application, in the sixth embodiment of the present application, the same or similar contents as those in the third embodiment can be referred to the above description, and will not be described in detail later. On this basis, the preset compression algorithm is the LZ4 compression algorithm, and step S50, encrypting the dictionary table in the position, and obtaining the encrypted data also includes step S52:

[0124] Step S52, encrypting the hash table in the position to obtain the encrypted data.

[0125] This embodiment takes the preset compression algorithm as the LZ4 compression algorithm as an example. Figure 3 As shown, Figure 3 This is a schematic diagram of the LZ4 compressed file format.

[0126] Among them, the LZ4 compressed file format includes LZ4 information, hash table and token data block. LZ4 uses hash table (dictionary table) to find matching strings. As long as part of the data in the hash table (dictionary table) is encrypted, the LZ4 compressed file will not be able to be decompressed. At the same time, the size of the hash table (dictionary table) is generally at the KB level, and the amount of data is very small, so the purpose of using smaller data encryption to protect larger files is achieved.

[0127] The present embodiment provides a firmware upgrade method, which obtains a marker block information set at a preset position in a pre-constructed encrypted upgrade package, decrypts the upgrade firmware at the corresponding position in the encrypted upgrade package based on the position information and encryption length in the marker block information set, obtains the decrypted upgrade firmware, and performs firmware upgrade based on the decrypted upgrade firmware, so that the firmware can be directly obtained for upgrading without decompressing the upgrade package, and the upgrade firmware at the corresponding position in the encrypted upgrade package is decrypted based on the position information and encryption length in the marker block information set, thereby shortening the decryption time and reducing the waiting time for firmware upgrade.
