The first address segment and the second address segment form a continuous address segment, and the field size of the first address segment is greater than the sum of the field sizes of the first sub-partition and the second sub-partition.

Specifically, the partition type of the first sub-partition is the fat type, and its size is 5M, which is used to store the interface login program of the Windows system. The partition type of the second sub-partition is Ext4 type, and its size is 10M, which is used to store the interface login program of the Linux system.

After the storage medium is connected to the user terminal, the login program associated with the terminal operating system enters the running state, and the login program in the running state provides a data read channel for the encrypted data partition. Therefore, this embodiment can effectively realize the compatibility of the storage medium in different operating systems, which is beneficial to improve the flexibility and convenience of the storage medium and further improve the use performance of the storage medium.

FIG. 4 schematically shows a flow chart of a method for accessing a storage medium according to an embodiment of the present disclosure. The execution body of the method may be, for example, a user terminal that has access to the storage medium. As shown in FIG. 4 , the method 400 may include operations S410˜S440.

In operation S410, a login program applicable to the current operating system in the login partition of the storage medium is executed.

In this embodiment, specifically, the storage medium includes a login partition divided on the first address segment and a data partition divided on the second address segment, the login partition includes at least two sub-partitions, and the at least two sub-partitions are used for storage Login programs for different operating systems, the data partition is used to store user data, and the data partition is encrypted.

After the storage medium is connected to the user terminal, run the login program suitable for the current operating system in the login partition of the storage medium, specifically, run the interface login program in the sub-partition suitable for the current operating system, so as to provide the user with the current operation Password input interface under the system. The interface login procedure can be implemented by using an existing algorithm, which will not be repeated in this embodiment.

Next, in operation S420, a decryption password input by the user based on the running login program is received.

In this embodiment, specifically, the decryption password input by the user based on the running login program is received, and specifically, the decryption password input by the user through the password input interface is received. By setting interface login programs associated with different operating systems, and using the interface login programs in the running state to provide users with a password input interface, the encrypted data reading channels for different operating systems are provided for users.

Next, in operation S430, it is verified whether the password can be decrypted, and if yes, the data partition of the storage medium is mounted.

In this embodiment, specifically, when verifying whether the decryption password can be approved, the decryption key associated with the decryption password is calculated according to a preset decryption algorithm; it is verified whether the decryption key is a legal key, and the data partition is mounted if it is. , wherein the decryption algorithm is applicable to different operating systems, and the decryption keys for data partitions under different operating systems are the same.

After receiving the decryption password input by the user through the password input interface, a decryption key associated with the decryption password is generated according to a preset decryption algorithm, combined with a random number generated inside the operating system and a preset number of iterations. Compare the generated decryption key with the pre-stored verification key for verifying the validity of the decryption password. When the two are consistent, determine that the decryption key is a valid key, and then determine that the decryption password entered by the user is Valid password. After determining that the decryption password input by the user is a valid password, mount the data partition of the storage medium, that is, mount the data files and file directories in the data partition into an accessible state.

FIG. 5 schematically shows a flow chart of storage medium access according to an embodiment of the present disclosure. After the interface login program associated with the current operating system in the login partition of the storage medium enters the running state, as shown in FIG. 5 , the storage medium displays the current Password input interface under the operating system (as shown in Figure 501). After receiving the decryption password entered by the user through the password input interface and determining that the decryption password can be approved, mount the data partition of the storage medium to make the data files and file directories in the data partition accessible (as shown in Figure 502 ) ).

Next, in operation S440, in response to the user's data access request, an access response operation based on the data access request is performed in the data partition.

In this embodiment, specifically, after the data partition is successfully mounted, in response to the user's data access request, according to the data access request, determine the target data that the user requests to access, and use the decryption key to decrypt the target data. , get the decrypted target data and display it.

When determining the target data requested by the user based on the data access request, determine the target address indicated by the data access request and request access by the user; according to the field size of the first address segment, perform an offset operation based on the target address to obtain the offset Address; take the user data indicated by the offset address as the target data, wherein the first address segment and the second address segment form a continuous address segment.

After the data partition is successfully mounted, the file directory in the data partition is accessible, but the data files in the data partition are still encrypted. When the user requests to read the target data, the decryption operation for the target data is performed, and the decrypted target data is obtained and displayed. Specifically, the user can select the file directory where the target data to be read is located by double-clicking or selecting an option, so as to realize the selection of the data address to be read. The terminal operating system generates a data access request based on the data address selected by the user, and transmits the data access request to the storage medium.

Based on the data access request, the disk drive or interface login program of the storage medium determines the target address that the user requests to read, and the target address is the absolute address of the target data in the storage medium, that is, the storage medium is not partitioned (that is, the entire storage medium constitutes data). data address in case of partition). In order to achieve compatibility with different operating systems, the storage medium in this embodiment is divided into a login partition and a data partition. Therefore, the relative position of the target data in the partitioned storage medium is different from that of the unpartitioned storage medium. Therefore, it is necessary to perform an offset operation on the target address that the user requests to read.

Specifically, an offset operation for the target address may be performed according to the field size of the first address segment to obtain the offset address. Since the first address segment and the second address segment form a continuous address segment, the target address can be offset by the field size of the first address segment to obtain the offset address. The user data indicated by the offset address is used as the target data to be decrypted, the decryption operation for the target data is performed, and the decrypted target data is displayed. In practical applications, the size of the first address segment is generally larger than the size of the field occupied by the login partition.

Exemplarily, the login partition of the storage medium includes two sub-partitions, wherein the partition type of one sub-partition is fat type, and its size is 5M, which is used to store the interface login program of the Windows system; the partition type of the other sub-partition is Ext4 type. , and its size is 10M, which is used to store the interface login program of the Linux system. After determining that the target address requested to be read by the user is A according to the data access request, it is necessary to offset the target address A according to the field size of the first address segment to obtain the offset address. Specifically, the field size of the first address segment is 50M, and the offset address for the target address A is A+50*1024*1024. In this example, the field size of the first address segment is greater than the sum of the field sizes of the two sub-partitions.

In the case where the storage medium is not encrypted, an encryption operation for the storage medium may be performed. Specifically, when the data partition is in an unencrypted state, the steps include: receiving an encrypted password input by a user through a login program; calculating an encryption key associated with the encrypted password according to a preset encryption algorithm; using the encryption key, Perform an encryption operation for the data partition, wherein the encryption algorithm is suitable for different operating systems, and the encryption keys for the data partition under different operating systems are the same. The encryption algorithm used for encrypting the storage medium is the same as the decryption algorithm used for decrypting the storage medium, and the adopted encryption and decryption algorithms are suitable for different operating systems.
