The present invention will be further described with reference to the following examples.
The normalization processing of the detection data after the duplication removal comprises the following design:
design 1:
designing a file format: the file is integrally divided into 5 parts, including: the file header, the master sector configuration table, the key sector, and the master sector. These 5 sections will be described and analyzed, respectively.
(1) File head
The file header is a fixed-length data segment located at the beginning of the whole file and takes on certain functions and tasks. In this study, the header is the most important part of the whole file composition, identifies the basic information of the file, records the parameters and composition of the master sector and the key sector, ensures the integrity of the file, and also carries a part of the master sector configuration table. The header is the root guarantee for file storage and exchange sharing.
(2) Main sector configuration table
The main sector configuration table is a table for recording the use condition of the main sector, records the use of the main sector of the whole file, and each 4 bytes in the table represent a sector, and the 4 bytes represent different use conditions of the sector, including conditions such as MSID of the next sector of the sector, whether the sector is the end of a sector chain, whether the sector is idle, and the like. The configuration table of the first 109 sectors in the main sector configuration table is located in the file header, and the configuration table after the 110 th sector is immediately after the file header. The number of sectors used by the main sector configuration table and the MSID of the first additional main sector configuration table are recorded in a file header and managed by the file header.
(3) Key sector configuration table
The key sector configuration table is a chapter table recording key sector usage. This table is a record of key sector usage, and like the master sector configuration table, the MSIDs of the first key sector configuration table of this table are all recorded in the file header. Unlike the master sector configuration table, the key sector configuration table is a set of 8 bytes, the first 4 bytes represent the first MSID of the master sector storing the ciphertext, and the last 4 bytes represent the first SKSID of the key sector corresponding to the ciphertext. It is specified that the key sector of a standard document has one and only one key sector configuration table, i.e. a standard document may contain at most a number of different secret information.
(4) Main sector
The main sector is a sector in which file data is stored. The standard file stores the data to be stored or exchanged and shared in the main sector after encryption. The number of main sectors and the size of each main sector are managed and controlled by a file header. The MSID of the next main sector is specified for the last 4 bytes in the main sector, and a sector chain end character is added if the sector chain ends to that sector.
(5) Key sector
The key sector is a sector in which a key is stored. The key is not stored in the key sector in the form of plaintext, but encrypted by an attribute base, and the encrypted ciphertext is stored in the key sector. When the receiving party has the corresponding authority (attribute), the secret key can be decrypted, and the secret information encrypted by the secret key is decrypted by the secret key through a symmetric encryption algorithm.
The file structure design is shown in fig. 7.
Design 2:
and (3) data format normalization design: the data normalization description method not only needs to uniformly design the whole file structure, but also needs to uniformly design the data format in the environment of the Internet of things, so as to realize uniform storage, exchange and sharing of data of different types, different storage structures and different coding modes. The address offset and parameters in the data format normalized design are shown in table 1.
Table 1 address offset and parameter table in data format normalization design
| Offset amount | Parameter(s) |
| 0H-3H | Data size |
| 4H-7H | Data type |
| 8H-9H | Storage structure |
| 10H-11H | Compression encoding method |
| 12H-1FBH | Data content |
| 1FCH-1FFH | Next sector MSID |
Note: the main sector size is 512 bytes.
The first 4 bytes in the data format normalization design shown in table 1 represent the size of the data represented by the data, i.e., the total number of bytes of the data, which is the total size of the plaintext and the stego information. The next 4 bytes represent the type of the data, including various text data, picture data, video data, and the like. Examples of the data types are shown in table 2.
Table 2 data type example table
| Numbering | File type |
| 00 00 00 00 | txt text data |
| 00 00 00 01 | jpg picture data |
| 00 00 00 02 | png picture data |
| 00 00 00 03 | mp4 view data |
| 00 00 00 04 | avi video data |
| 00 00 00 05 | Custom data format |
| …… | …… |
The 8 th bit and the 9 th bit of the data format normalization design represent the storage structure of data, and common data storage structures include a sequential storage structure, an index storage structure, a hash structure storage, a tree storage structure, and the like. A data structure representation is shown in table 3.
Table 3 data structure example table
| Numbering | Data structure |
| 00 01 | Sequential storage structure |
| 00 02 | Index storage structure |
| 00 03 | Hash storage structure |
| 00 04 | Red and black tree storage structure |
| 00 05 | B + number storage structure |
| …… | …… |
The 10 th bit and the 11 th bit of the data format normalized design represent the compression encoding mode of the data. Many data can compress and encode the size of the data in the storage process, thereby reducing the storage space used by the data, optimizing the data storage efficiency, accelerating the data exchange and sharing and the like. The compression-encoded bits of the data are one record of the compression-encoding method of the data. An example of the data compression encoding method is shown in table 4.
Table 4 example table of data compression coding mode
| Numbering | Data compression coding mode |
| 00 00 | Zip compression |
| 00 01 | war compression |
| 00 02 | Huffman coding |
| 00 03 | AAC coding |
| 00 04 | 0gg coding |
| …… | …… |
The normalized design of the data format is the content of the data starting from bit 12. The last 4 bits of each main sector are MSIDs identifying the next sector, and when the data storage is finished, the data end identifier FF FEH is added, and the sector linking end identifier FF FFFF FEH is added to the last 4 bits of the sector, indicating that the data storage is finished.
After the data is stored in the main sector, the use condition of all the main sectors needs to be recorded in the main sector configuration table, and the function of recording each main sector configuration table is recorded. The sector configuration table (master sector and key sector are the same) has the same identifier as shown in table 5.
Table 5 sector configuration table identification
Design 3:
design supporting data privacy protection: in the data normalization description method, an attribute-based encryption technology based on a ciphertext strategy is adopted to support the privacy security of the whole data. Therefore, the version number of the attribute table is added into the file carrying data for managing the global attribute table; the file designs a key sector for storing an encryption key used for symmetric encryption after being encrypted by using the attribute set; the file can only store encrypted ciphertext in the main sector, and cannot be directly stored by using plaintext. The file is matched with the main sector through the file header, the key sector and the main sector, so that the influence caused by the difference of the data type and the data structure is shielded, and the data privacy protection work is completed. The process is as follows:
(1) generating a random AES key by adopting an AES encryption algorithm to encrypt the file data;
(2) storing the decrypted ciphertext in the main sector;
(3) encrypting the AES key by adopting an attribute-based encryption algorithm;
(4) and storing the cipher text after the encryption of the key in the key sector.
Design 4:
designing a file header: the data normalization description method erases original characteristic information of data and stores the encrypted ciphertext and the encrypted secret key. In order to ensure the availability of data and enable a receiver to smoothly receive, store and decrypt the data, the attributes of a file bearing the data need to be marked and managed in a file header mode, and each platform in a large-scale internet of things system can effectively process the file.
The file header is specified as 512 bytes, which is the same as a common compound document file header. The file header stores basic attribute information of the file, sector attribute information and a partial main sector configuration table. The detailed design of the header is shown in table 6.
Table 6 file header design table
| Number of bytes | Means of |
| 0H-7H | Document identifier |
| 8H-17H | Unique file identifier |
| 18H-19H | File format revision number |
| 1AH-1BH | File version number |
| 1CH-1DH | Attribute table version number |
| 1EH-1FH | Byte order identification |
| 20H-23H | File source numbering |
| 24H-27H | Minimum size of standard file |
| 28H-29H | Size of main sector |
| 2AH-2BH | Secret key sector man-small |
| 2CH-2FH | SID of first main sector |
| 30H-33H | Number of sectors used by the main sector |
| 34H-37H | SID of first key sector |
| 38H-3BH | Number of sectors used by key sector |
| 3CH-3FH | SID of first main sector configuration table |
| 40H-43H | Number of sectors used by master sector configuration table |
| 44H-47H | SID of key sector configuration table |
| 48H-49H | CRC checking |
| 4AH-4BH | Is not used |
| 4CH-1FFH | A portion of a master sector configuration table |
The 0H to 27H of the header store basic attributes of the file, including a document identifier, a file unique identifier, a file format revision number, a file version number, an attribute table version number, a byte order identifier, a file source number, and a standard file minimum size. The file identifier, the file format revision number, the file version number and the attribute table version number are managed and controlled by a unified mechanism, and the unique file identifier, the byte sequence identifier, the file source number and the standard file minimum size are generated by a sender. The byte order identification is divided into a big-end mode and a small-end mode, wherein the big-end mode is represented by FF FEH, and the small-end mode is represented by FEFFH.
The 28 th to 47 th of the document header store the sector attributes including the master sector size, the key sector size, the SID of the first master sector, the number of sectors used by the master sector, the SID of the first key sector, the number of sectors used by the key sector, the SID of the first master sector configuration table, the number of sectors used by the master sector configuration table, and the SID of the key sector configuration table. Wherein the master sector size and the key sector size are expressed in powers of 2, typically 9, i.e. 512 bytes; when the first master sector configuration table is not present, it is represented using-2 (FF FFFF FEH); the key sector configuration table is one and only one in a standard file.
Bits 48 to 49 of the header store the CRC check bits of the file. After the file completes the data structure normalization, the normalized data is processed through the CRC16 algorithm to generate CRC check bits of two bytes, and after the receiver decrypts the file, the same CRC16 algorithm is used for plaintext to obtain the CRC check bits of the receiver. The receiver compares the CRC check bits generated by calculation with the CRC check bits in the file header to judge whether the file has error codes, is lost, is tampered and the like, and if the two CRC check bits are the same, the file is complete, so that the integrity of the file is ensured. The 4 th AH to 4BH of the file are unused bits, and the data bits are not uniformly defined for use.
The 4CH to 1FFH of the header stores a portion of the file master sector configuration table. This part stores the use of the first 109 sectors, and when the number of sectors is less than 109, the remaining part is represented by-1 (FF FFFF FFH). When the number of sectors is larger than 109, an additional sector is generated for storing the main sector configuration table, the MSID of the table is stored in the SID bit of the first main sector configuration table in the file header, and when the sector is not enough to store all sectors, the next sector is continuously used to add the main sector configuration table until all sector states are stored in the main sector configuration table.
A complete illustration of the header is shown in fig. 8.
