[0061] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application usually described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, each other embodiment obtained by those skilled in the art without making creative work belongs to the scope of protection of the present application.
[0062] After research, it was found that, currently, in the process of importing virtual materials into products, the product needs to be restarted after importing the virtual materials in order to use the corresponding effects of the virtual materials and obtain the import results; among them, after the virtual materials are written into the product, due to the lack of storage space protection, it is easy for the storage space to be accidentally cleared, which will cause the data stored in the product storage space to be erased when the product goes offline, resulting in the product being unable to be authorized and authenticated.
[0063] In addition, after the product imports virtual materials, the product will be vulnerable to attacks because the instruction response function of the virtual materials still exists. The writing process of virtual materials lacks a confidentiality mechanism, and the virtual materials covering the user's security information are at risk of leakage, which reduces the security and accuracy of writing virtual materials into the product, and thus reduces the stability of the product.
[0064] Based on this, an embodiment of the present application provides a method for writing virtual materials, in which the upper end encrypts the data of the virtual materials and sends it to the product end, so that the product end writes the target virtual materials into a non-volatile storage space set in the product end, and performs a consistency check on the target virtual materials after writing them. After the check is passed, the target virtual materials are activated, so that the target virtual materials take effect in the product end, thereby improving the security and accuracy of writing virtual materials into products, and thereby improving the stability of the products.
[0065] See also Figure 1 , Figure 1 This is one of the flow charts of a method for writing virtual materials provided in an embodiment of the present application. Figure 1 As shown in, the virtual material writing method provided in the embodiment of the present application is generally applied to the virtual material writing system, the writing system includes a host computer end and a product end, and the writing method includes:
[0066] S101. The host computer encrypts the data of the pre-imported virtual material to obtain the target virtual material, and sends the target virtual material to the product end.
[0067] In the embodiments of the present application, virtual materials refer to data information for realizing specific functions of a product; the product end generally refers to a device with information processing and control capabilities.
[0068] Exemplarily, the virtual materials may include but are not limited to files, information data, program packages and security data, etc.; the product end may include but is not limited to a vehicle device, a processing device, a computing device and a control device, etc.
[0069] The product end is generally configured with at least one processor and one controller, and is also configured with other devices or modules; the host computer end communicates data with the product end through a preset communication bus.
[0070] In this step, during the specific implementation, first, the external side will pre-import the virtual materials to the host computer side according to the corresponding requirements for the product side; then, the host computer side will encrypt the virtual materials using a preset encryption algorithm to obtain the target virtual materials; finally, the target virtual materials will be sent to the product side using the communication bus pre-established between the host computer side and the product side.
[0071] In one implementation of the present application, during specific implementation, step S101 may include:
[0072] S1011. The host computer encrypts the pre-imported virtual material data using a preset encryption method to obtain a target virtual material, and sends the name data corresponding to the target virtual material to the product end.
[0073] In the embodiment of the present application, the preset encryption algorithm may include a secure hash algorithm, such as the SHA-512 algorithm (Secure Hash Algorithm 512).
[0074] Specifically, when the encryption algorithm is the SHA-512 algorithm, the virtual material is encrypted through the following steps to obtain the target virtual material: first, the virtual material is padded to a specific length and divided into blocks of a fixed size; then, a set of initial hash values (e.g., H0, H1, ..., H7) is set, and the initial hash value is a constant specified by NIST; thereafter, a series of operations including logical operations, modular addition, displacement and rotation are applied to each message block; finally, after all blocks are processed, the final hash values are connected as output to obtain the target virtual material.
[0075] In this step, after obtaining the target virtual material, the name data corresponding to the target virtual material is first sent to the product end, so that the product end creates a blank virtual material based on the name data.
[0076] S1012: In response to the product end having created the virtual material corresponding to the name data, sending content data corresponding to the target virtual material to the product end.
[0077] In this step, when a response signal is obtained from the production end indicating that the virtual material corresponding to the name data has been created, the content data corresponding to the target virtual material is sent to the product end.
[0078] As an example of sending the name data corresponding to the target virtual material to the product end, assume that the certificate file (target virtual material) is sent to the vehicle device end (product end). First, the host computer sends the file name data corresponding to the certificate file to the vehicle device end; then, after the host computer receives the response signal that the file name data has been written into the vehicle device, the content data corresponding to the certificate file is sent to the vehicle device end; finally, the host computer receives the response signal that the content data has been written into the vehicle device.
[0079] S102: The product end receives the target virtual material, and writes the target virtual material into a non-volatile storage space provided in the product end.
[0080] In the embodiment of the present application, the non-volatile storage space refers to a FLASH storage space, which can save data after the device is powered off. FLASH storage is based on floating gate transistor technology. Each storage cell consists of a floating gate and a control gate. By applying voltage to the control gate, electrons can be "tunneled" into or out of the floating gate, thereby changing its charge state. These two states represent 0 and 1 in binary data.
[0081] A security area is reserved in advance in the non-volatile storage space for storing target virtual materials, and the data in the security area is set to be non-erasable.
[0082] In this step, during the specific implementation, first, the product end receives the name data corresponding to the target virtual material and determines the material type of the target virtual material; then, based on the material type and name data, a blank virtual material is created in the non-volatile storage space set in the product end; thereafter, the received content data sent by the host computer end is written into the blank virtual material to write the target virtual material into the non-volatile storage space; finally, the writing result of the target virtual material is sent to the host computer end.
[0083] In an embodiment of the present application, the target virtual material may include but is not limited to name data and content data; here, the data frame in the target virtual material may include a start frame, an intermediate frame and an end frame, wherein the start frame and the end frame in the data frame must exist, the intermediate frame can be 0 frames or multiple frames, and the start frame and the end frame are used by the product end to determine the start and end of each data frame of the target virtual material.
[0084] Furthermore, while the product end receives the target virtual material sent by the host computer end and writes the target virtual material into the non-volatile storage space, the product end can also receive external virtual materials sent by the user, and in response to receiving the external virtual material, write the external virtual material into the non-volatile storage space.
[0085] In one implementation of the present application, during specific implementation, step S102 may include:
[0086] S1021. The product end receives name data corresponding to the target virtual material, and determines a material type corresponding to the target virtual material based on the name data.
[0087] In this step, the product end receives the name data corresponding to the target virtual material sent by the host computer end, and determines the material type corresponding to the target virtual material based on the name data.
[0088] When receiving the name data corresponding to the target virtual material, the product end sequentially receives the start frame, the middle frame and the end frame corresponding to the name data to record the data corresponding to the middle frame.
[0089] For example, when sending a security password certificate file (target virtual material) to the vehicle device end (product end), based on the name corresponding to the security password certificate, it can be determined that the material type corresponding to the target virtual material is the security certificate type.
[0090] S1022. Based on the material type and the name data, create a blank virtual material in a non-volatile storage space set in the product end.
[0091] In this step, the product end creates a blank virtual material in a non-volatile storage space (FLASH storage space) provided in the product end based on the material type and name data; wherein the blank virtual material is used to write content data corresponding to the target virtual material.
[0092] Furthermore, after creating the blank virtual material, the product end writes the name data and sends the result of creating the blank virtual material to the host computer end.
[0093] S1023. In response to receiving the content data corresponding to the target virtual material, write the content data into the blank virtual material to write the target virtual material into the non-volatile storage space, and send the writing result of the target virtual material to the host computer.
[0094] In this step, during the specific implementation, first, the product end receives the content data corresponding to the target virtual material sent by the host computer end; then, the start frame, middle frame and end frame corresponding to the content data are written into the blank virtual material in sequence, so as to write the target virtual material into the non-volatile storage space; finally, the writing result of the target virtual material is sent to the host computer end.
[0095] S103: In response to the target virtual materials being written into the non-volatile storage space, a consistency check is performed on the target virtual materials to obtain a check result.
[0096] In an embodiment of the present application, the verification method for consistency verification of the target virtual material is determined by the host computer end and the product end through negotiation in advance for the target virtual material; wherein, the consistency verification may include multiple verification methods. In an embodiment of the present application, the consistency verification between the host computer end and the product end is generally a hash value verification.
[0097] In one implementation of the present application, during specific implementation, step S103 may include:
[0098] S1031. In response to the target virtual materials being written into the non-volatile storage space, a calibrated virtual material corresponding to the target virtual material is obtained in a cloud server, and a first hash value corresponding to the calibrated virtual material is calculated.
[0099] In this step, to ensure the consistency of the target virtual material in the non-volatile storage space, the product end obtains the calibrated virtual material corresponding to the target virtual material from the cloud server, and uses a preset cryptographic hash function to calculate the first hash value corresponding to the data in the calibrated virtual material.
[0100] In the embodiment of the present application, the hash value generally refers to an MD5 (Message-Digest Algorithm 5) hash value. The cryptographic hash function can receive a message of any length and generate a 128-bit (16-byte) fixed-length hash value or "message digest".
[0101] S1032: Calculate a second hash value corresponding to the data in the target virtual material, and compare the second hash value with the first hash value for consistency, to obtain a verification result of a consistency verification of the target virtual material.
[0102] In this step, during the specific implementation, first, based on the data in the target virtual material, a second hash value corresponding to the data is calculated using a preset cryptographic hash function; then, the second hash value is compared with the first hash value for consistency; finally, a verification result of the consistency verification of the target virtual material is obtained.
[0103] Among them, when the second hash value is inconsistent with the first hash value, the verification result of the consistency check on the target virtual material is determined to be failed; when the second hash value is consistent with the first hash value, the verification result of the consistency check on the target virtual material is determined to be passed.
[0104] S1033. Send the verification result to the host computer.
[0105] In this step, the product end sends the consistency verification result of the target virtual material and the calibrated virtual material to the host computer end through a preset communication bus.
[0106] S104: In response to the verification result being that the consistency verification is passed, activating the target virtual material to make the target virtual material effective in the product end.
[0107] In this step, during the specific implementation, first, in response to the verification result of the target virtual material being through the consistency check, the target virtual material is activated in the product end so that the target virtual material takes effect in the product end; then, the effectiveness status of the target virtual material is sent to the upper computer end; finally, based on the effective target virtual material, the product end is activated for the corresponding function or indication of the target virtual material.
[0108] Optional, see Figure 2 , Figure 2 This is a second flow chart of a method for writing virtual materials provided in an embodiment of the present application. Figure 2 As shown in, in addition to the method for writing virtual materials described in steps S101 to S104, the embodiment of the present application also includes step S105. Specifically, step S105 is used to illustrate a method for ensuring that the target virtual material cannot be written or deleted after the target virtual material takes effect in the product end, so as to improve the security of the target virtual material being written to the product end.
[0109] S105. In response to the target virtual material becoming effective, the product end closes access rights to the target virtual material and activates a protection mechanism for the non-volatile storage space to ensure that the target virtual material cannot be written or deleted.
[0110] In this step, during the specific implementation, first, the product side responds to the target virtual material being effective by closing the access rights for writing the target virtual material, that is, when the host computer side issues relevant instructions for the target virtual material again, the product side will not respond; then, the protection mechanism of the non-volatile storage space is enabled to ensure that the target virtual material stored in the non-volatile storage space cannot be written or deleted; finally, the product side sends the instruction information of the above actions to the host computer side.
[0111] The method for writing virtual materials provided in the embodiment of the present application encrypts the data of the virtual materials through the upper end and sends it to the product end, so that the product end writes the target virtual materials into the non-volatile storage space set in the product end, and performs a consistency check on the target virtual materials after writing them. After the check is passed, the target virtual materials are activated, so that the target virtual materials take effect in the product end, thereby improving the security and accuracy of writing virtual materials into products, and further improving the stability of the products.

[0119] The pre-imported virtual material is encrypted using a preset encryption method to obtain the target virtual material.

[0121] Send the name data corresponding to the target virtual material to the product end;
[0122] In response to the product end having created the virtual material corresponding to the name data, the content data corresponding to the target virtual material is sent to the product end.
