With the increasing popularity of SSD products, more and more SSD products are required to support TCG (Thin-State Delivery Code) functionality to enhance the security of SSD data.
[0003] Within the TCG module, the Transaction function provides a convenient and simple way to modify and apply changes to the SP (Service Provider), and also a convenient way to handle error behavior. However, traditional technical solutions do not offer a complete technical solution for implementing the Transaction function in the SSD TCG module. Summary of the Invention
[0004] Therefore, it is necessary to provide a method, apparatus, computer device, and storage medium for implementing the Transaction function in an SSD TCG module to address the aforementioned technical problems.

[0038] Figure 7 This is an internal structural diagram of a computer device in one embodiment. Detailed Implementation
[0039] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0040] In one embodiment, such as Figure 1 As shown, a method for implementing the Transaction function in an SSD TCG module is provided, the method including:
[0041] Step 102: Create two spaces in the non-user data area to store two identical SP data, including the first SP data and the second SP data.
[0042] Step 104: When changes occur within a Transaction, only update the data of the first SP;
[0043] Step 106: When the Transaction is aborted, use the second SP data to restore the first SP data and the local SP data;
[0044] Step 108: When the Transaction is closed, the changes to the first SP data take effect immediately and the first SP data is copied to the second SP data.
[0045] In this embodiment, a method for implementing the Transaction function applied to the SSD TCG module is provided. This method utilizes the design of dual backup of SP data. When the Transaction is opened, only one copy is updated. When the Transaction is aborted, the SP table that has not been updated is used to restore it. When the Transaction is closed, both copies of the SP table are updated.
[0046] First, two spaces are allocated in the non-user data area to store two identical SP data, including the first SP data SP_A and the second SP data SP_B.
[0047] The Transaction function is optional in the TCG module. The protocol stipulates that a Transaction must exist in an open session. When the session is aborted, the Transaction must also be aborted.
[0048] When a method is invoked outside of a transaction, the changes take effect immediately and are persisted.
[0049] When a method is called within a Transaction, it remains active until the Transaction is committed. If a Transaction is aborted, all changes made within the Transaction must be rolled back, and the SP's state must be restored to its state before the Transaction began.
[0050] Changes made to SPs within a Transaction are considered to be effective until the Transaction ends.
[0051] Specifically, refer to Figure 2 The diagram shown illustrates the process of a transaction being aborted. Changes made within a transaction only take effect on SP_A. When aborted, SP_A and the local SP are restored using SP_B.
[0052] Specifically, refer to Figure 3 The diagram shows the process of a transaction taking effect. When the transaction closes, the changes in SP_A take effect immediately and are copied to SP_B.
[0053] In this embodiment, two spaces are allocated within the non-user data area to store two identical SP data sets, namely a first SP data set and a second SP data set. When changes occur within a Transaction, only the first SP data set is updated. When a Transaction is aborted, the first SP data set and the local SP data set are restored using the second SP data set. When a Transaction is closed, changes to the first SP data set take effect immediately, and the first SP data set is copied to the second SP data set. This invention improves the functionality of the TCG module, implements the Transaction function, and allows for the rollback of changes when a Transaction is aborted while it is in progress.
[0054] In one embodiment, such as Figure 4 As shown, a method for implementing the Transaction function in an SSD TCG module is provided, which further includes:
[0055] Step 402: Enable the Transaction function, execute TCG cmd and update the SP table;
[0056] Step 404: Update the local SP data and the first SP data according to the TCG cmd;
[0057] Step 406: When the TCG module receives the abort cmd, it uses the second SP data to restore the first SP data and restores the local SP data, and the rollback is successful.
[0058] Step 408: When the TCG module receives the End transaction cmd, it copies the updated first SP data to the second SP data to make the two SP data consistent.
[0059] For specific details, please refer to Figure 5 The flowchart shown illustrates the implementation method of the Transaction function applied to the SSD TCG module. The specific implementation steps are as follows:
[0060] Step 5.1: Start the transaction.
[0061] Step 5.2: Execute TCG cmd, such as SET method, to update SPtable.
[0062] Step 5.3: Update the local SP data and update SP_A according to the TCG cmd.
[0063] Step 5.4, Case 1: The TCG module receives the abort cmd, restores SP_A using SP_B, restores the local SP, and the rollback is successful.
[0064] Step 5.5, Case 2: Upon receiving the Endtransaction cmd, use SP_A to update SP_B, and the changes will take effect.
[0065] In this embodiment, the Transaction function provides a relatively convenient and simple way to modify and make changes to the SP, and it is also a convenient way to handle erroneous behavior. In this embodiment, the changes made to the TCG SP within the Transaction can be rolled back to the version before the Transaction when the Session aborts.
[0066] It should be understood that, although Figures 1-5 The steps in the flowchart are shown sequentially as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order in which these steps are executed, and they can be performed in other orders. Figures 1-5 At least some of the steps in the process may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least some of the sub-steps or stages of other steps.
[0067] In one embodiment, such as Figure 6 As shown, a Transaction function implementation device 600 for an SSD TCG module is provided, the device comprising:
[0068] Data storage module 601, wherein the data storage module opens two spaces in the non-user data area to store two identical SP data, including the first SP data and the second SP data;
[0069] Data update module 602, the data update module is used to update only the first SP data when changes occur within the Transaction;
[0070] Data recovery module 603, the data recovery module is used to recover the first SP data and local SP data using the second SP data when the Transaction is terminated;
[0071] The data replication module 604 is used to ensure that changes to the first SP data take effect immediately and to replicate the first SP data to the second SP data when the Transaction is closed.
[0072] In one embodiment, the data update module 602 is further configured to:
[0073] Enable the Transaction function, execute the TCG command and update the SP table;
[0074] Update local SP data and first SP data according to TCG cmd.
[0075] In one embodiment, the data recovery module 603 is further configured to:
[0076] When the TCG module receives the abort cmd, it uses the second SP data to restore the first SP data and restores the local SP data, thus successfully rolling back.
[0077] In one embodiment, the data replication module 604 is further configured to:
[0078] When the TCG module receives the End transaction cmd, it copies the updated first SP data to the second SP data to make the two SP data consistent.
