Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and in particular to an encrypted login method, device, electronic device, and storage medium for a vehicle infotainment system. Background Technology

[0002] Currently, secure login technology for in-vehicle infotainment systems mainly relies on traditional encryption methods and operating system security mechanisms, but this has significant limitations:

[0003] 1. Lack of dynamic binding mechanism: Most in-vehicle systems use preset passwords or fixed keys for user login authentication, lacking a dynamic binding mechanism. For example, although GAC's in-vehicle Ethernet dynamic login solution introduces public key authentication, the private key is still centrally managed by the server, failing to achieve unique binding to the terminal hardware. Attackers can obtain the key through reverse engineering or man-in-the-middle attacks, posing a risk of large-scale intrusion due to unified key leakage.

[0004] 2. Secure boot and anti-tampering technologies have limitations. While automotive operating systems such as QNX (a real-time operating system) provide Secure Boot and QTD (QNX Trusted Disk) integrity protection, they do not associate them with the chip's physical identifier. QTD technology verifies file system block hashes based on Merkle trees and relies on RootHash signature protection, but it can only detect tampering and cannot achieve dynamic authentication during the boot phase. Such mechanisms cannot prevent legitimate images from running on unauthorized devices and are not integrated with the user login process.

[0005] 3. Balancing development / debugging with production security is difficult. During the development phase, traditional solutions rely on fixed backdoor passwords or open permissions. For example, the Mazda CMU in-vehicle infotainment system suffered from an SQL injection vulnerability, allowing attackers to execute arbitrary code with root privileges. Existing technologies lack secure, isolated debugging channels, making them vulnerable to exploitation by hackers.

[0006] 4. The keys lack a hardware binding mechanism. Even when using the Vehicle Identification Number (VIN) as an authentication factor, most solutions simply store it statically in the OEM partition without dynamically associating it with the chip's unique identifier. For example, PATEO's vehicle networking patent relies on a Direct Memory Access (DMA) controller to manage serial port data, but it does not involve key generation logic. Hackers can bypass verification by cloning the entire device's flash memory data. Summary of the Invention

[0007] The purpose of this invention is to provide an encrypted login method, device, electronic device, and storage medium for a vehicle infotainment system, so as to at least solve the problem of poor security in existing vehicle infotainment system login technologies and help ensure the security of the vehicle infotainment system.

[0022] Optionally, the step of generating the dynamic key based on the vehicle's VIN code using a preset encryption method, and then completing the login to the vehicle system based at least on the dynamic key, specifically includes:

[0023] Calculate the hash value corresponding to the vehicle's VIN code and convert the hash value into a hash string in a first preset base;

[0024] Obtain the hash character at a preset position within the hash string and convert the hash character into an index character in a second preset base;

[0026] Extract a pre-defined length of encoded string from the encoded result and use the encoded string as the dynamic key to complete the login to the vehicle system based at least on the dynamic key.

[0027] Secondly, the present invention also provides an encrypted login device for a vehicle infotainment system, comprising at least:

[0028] A configuration acquisition module is used to acquire the chip serial number of the vehicle infotainment system configuration chip, so as to generate a serial configuration file based at least on the chip serial number;

[0029] A standard configuration module is used to obtain the verification value of the sequence configuration file, so as to generate a standard configuration file based at least on the sequence configuration file and the verification value;

[0030] The startup verification module is used to verify the standard configuration file in response to the startup of the vehicle system in order to obtain the verification result;

[0031] The login verification module is used to set environment variables based on the verification result and to complete the login to the vehicle system based at least on the environment variables.

[0054] Figure 1 This is a flowchart of an encrypted login method for a vehicle infotainment system provided by an embodiment of the present invention. This embodiment is applicable to encrypted login scenarios for various types of vehicle infotainment systems. The encrypted login method for this vehicle infotainment system can be, but is not limited to, executed by the encrypted login device of the vehicle infotainment system in this embodiment of the present invention. This execution entity can be implemented in software and / or hardware. Figure 1 As shown, the encrypted login method of this vehicle infotainment system includes at least the following steps:

[0055] S1. Obtain the chip serial number of the vehicle infotainment system configuration chip, and generate a serial configuration file based at least on the chip serial number.

[0056] The in-vehicle infotainment system (IVR) chip can be a Qualcomm chip, typically stored in registers. The chip serial number can be a unique identifier for the Qualcomm chip. In one specific implementation, the chip serial number can be read via a dedicated pipeline job. The serial configuration file can be a syscfg.bin file. It is understood that after the syscfg.bin configuration file is generated, it can be written to a separate syscfg partition (or to an encrypted storage area stored in the security chip (eSE / TPM)), allowing it to be securely read directly during subsequent verification of the standard configuration file.

[0057] S2. Obtain the checksum of the sequence configuration file, and generate a standard configuration file based at least on the sequence configuration file and the checksum.

[0058] The checksum can be obtained by reading the first 60 bytes of the syscfg.bin configuration file within the syscfg partition, hashing the first 60 bytes using the SHA-256 algorithm, and then obtaining the checksum. The standard configuration file generation method involves appending a checksum to the sequence configuration file.

[0059] S3. In response to the startup of the vehicle's infotainment system, verify the standard configuration file to obtain the verification result.

[0060] The verification sequence configuration file can be used to verify the verification values ​​in the verification sequence configuration file. By comparing the locally reserved hash value with the verification value, the verification is considered successful if they match, and unsuccessful otherwise. In another specific implementation, the verification result may optionally include at least a verification failure result and a verification success result.

[0061] S4. Set environment variables based on the verification results, and complete the login to the vehicle system based at least on the environment variables.

[0062] The environmental variables are used to determine the operating environment of the vehicle infotainment system. The operating environment of the vehicle infotainment system may include a development environment and a production environment. In another specific implementation, optionally, the environmental variables include at least environment success variables and environment failure variables.

[0063] The technical solution provided in this embodiment first obtains the chip serial number of the vehicle infotainment system configuration chip to generate a serial configuration file based at least on the chip serial number; second, obtains the verification value of the serial configuration file to generate a standard configuration file based at least on the serial configuration file and the verification value; then, in response to the startup of the vehicle infotainment system, verifies the standard configuration file to obtain the verification result; finally, sets environment variables based on the verification result and completes the login to the vehicle infotainment system based at least on the environment variables.

[0064] Therefore, this embodiment, on the one hand, generates a serial configuration file based on the chip serial number, and on the other hand, generates a standard configuration file based on the serial configuration file and the checksum. This enables a strong binding relationship between the configuration file and the vehicle's configuration chip, effectively preventing unauthorized devices from starting. On the other hand, this embodiment sets environment variables through the checksum results, which can effectively isolate the development / production environment and further ensure the security of the vehicle's infotainment system.

[0065] Based on the above embodiments or implementation methods Figure 2 This is a flowchart of another encrypted login method for a vehicle infotainment system provided in an embodiment of the present invention. Figure 7 This is a timing diagram of an encrypted login method for a vehicle infotainment system provided in an embodiment of the present invention. This embodiment is based on the above embodiment with additions. Figure 2 and Figure 7 As shown, the encrypted login method of this vehicle infotainment system includes at least the following steps:

[0066] S1. Obtain the chip serial number of the vehicle infotainment system configuration chip, and generate a serial configuration file based at least on the chip serial number.

[0067] Understandably, when generating the serial configuration file, the first step is to copy / download gen_syscfg_img.py (a utility script) from the local machine or a specified address. Further, developers manually configure relevant parameters such as release_addr (version address), applicant_email (applicant email), adb_value (ADB function configuration), uart_value (serial port function configuration), and selinux_value (SELinux security configuration). Further still, developers set adb_value and uart_value based on the on / off states of ENABLE_ADB and ENABLE_UART. Finally, after setting adb_value and uart_value, gen_syscfg_img.py can be called to process the DEVICE_ID (chip serial number) to generate the filename syscfg.bin and its associated info filename, thereby generating the syscfg.bin configuration file.

[0068] S2. Obtain the checksum of the sequence configuration file, and generate a standard configuration file based at least on the sequence configuration file and the checksum.

[0069] As an alternative, this embodiment can also use a device unique certificate (PKI system) signature configuration file instead of a verification value to avoid serial number forgery.

[0070] S3. In response to the startup of the vehicle's infotainment system, verify the standard configuration file to obtain the verification result.

[0071] S41. Set the environment variable as an environment success variable based on the successful verification result.

[0072] Setting an environment variable as a success variable can be achieved by setting the corresponding environment variable value to 1. For example, when ENV_OK is set to 1, it is considered that the current environment variable is a success variable.

[0073] S42. At least after the environment variables are set to the environment success variables, the vehicle system enters the development environment and directly completes the login of the vehicle system.

[0074] Understandably, when the vehicle infotainment system is in a development environment, it can automatically log in without requiring a dynamic password.

[0075] Therefore, this embodiment, on the one hand, generates a serial configuration file based on the chip serial number, and on the other hand, generates a standard configuration file based on the serial configuration file and the checksum. This enables a strong binding relationship between the configuration file and the vehicle's configuration chip, effectively preventing unauthorized devices from starting. On the other hand, this embodiment sets environment variables through the checksum results, which can effectively isolate the development / production environment and further ensure the security of the vehicle's infotainment system.

[0076] See also Figure 7 Based on the above embodiments or implementation methods, Figure 3 This is a flowchart of another encrypted login method for a vehicle infotainment system provided by an embodiment of the present invention. This embodiment is based on the above embodiment and includes additional steps. Figure 3 As shown, the encrypted login method of this vehicle infotainment system includes at least the following steps:

[0077] S1. Obtain the chip serial number of the vehicle infotainment system configuration chip, and generate a serial configuration file based at least on the chip serial number.

[0078] S2. Obtain the checksum of the sequence configuration file, and generate a standard configuration file based at least on the sequence configuration file and the checksum.

[0079] S3. In response to the startup of the vehicle's infotainment system, verify the standard configuration file to obtain the verification result.

[0080] S43. Set the environment variable as the environment failure variable based on the verification failure result.

[0081] Setting an environment variable as an environment failure variable can be achieved by setting the corresponding environment variable value to 0. For example, when ENV_OK is 0, it is considered that the current environment variable is an environment failure variable.

[0082] S44. At least after the environment variable is set to the environment failure variable, the vehicle system enters the production environment and reads the vehicle VIN code.

[0083] Among them, the vehicle identification number (VIN) can be a vehicle identification code that can uniquely identify a vehicle.

[0084] S45. Generate a dynamic key based on the vehicle's VIN code using a preset encryption method, and complete the login to the vehicle system based on at least the dynamic key.

[0085] The dynamic key can be generated differently for different vehicle VIN codes, achieving one key per vehicle. As an alternative, this embodiment can also generate a dynamic key based on real-time vehicle data (such as GPS location and timestamps). In yet another specific implementation, step S45 may optionally include:

[0086] (45-1) Calculate the hash value corresponding to the vehicle's VIN code and convert the hash value into a hash string in the first preset base.

[0087] The hash value can be calculated using the SHA256 hash algorithm. The first preset base can be hexadecimal.

[0088] (45-2) Obtain the hash character at a preset position within the hash string and convert the hash character into an index character in the second preset base.

[0089] The preset position can be the 16th character (index 15). The second preset base can be decimal.

[0090] (45-3) Perform encoding operations on the index characters to obtain the encoding results.

[0091] The encoding operation can be Base64 encoding.

[0092] (45-4) Extract the encoded string of a preset length from the encoded result and use the encoded string as a dynamic key to complete the login of the vehicle system based on at least the dynamic key.

[0093] The encoded string can be obtained by extracting 16 characters (preset length) from the index position in the encoded result as the dynamic key.

[0094] In yet another specific implementation, the technical solution provided by this embodiment can be specifically as follows:

[0095] First, obtain the chip serial number via `getserial` or hardware methods. Next, use the Jennifer's job pipeline tool to read and input the serial number to obtain the `syscfg.bin` configuration file. Then, connect the hardware, enter the serial port, type `reset -f` to enter fastboot mode, and use `fastboot flash syscfg syscfg.bin` to flash the `syscfg` file to the partition. After the vehicle's infotainment system boots, connect to the serial port. If the `syscfg` file has been flashed, login is possible without a password. If the `syscfg` file has not been flashed, login is required. Further, the vehicle's VIN is extracted and the following calculation process is executed: B = VIN's SHA256 hash value (hexadecimal string); C = B converted to binary and then base64 encoded, removing newlines; char_index = the 16th character of B; if char_index is "af", it is converted to decimal (a=10, b=11, ..., f=15); password = starting from the +1 character of C, 16 characters are extracted; the dynamic password is output: cBgUpEHi3H2+ucW4. Finally, the vehicle system login is completed based on the dynamic password.

[0096] In summary, this embodiment generates a serial configuration file based on the chip serial number and a standard configuration file based on the serial configuration file and the checksum, which enables a strong binding relationship between the configuration file and the vehicle's infotainment system chip, effectively preventing unauthorized devices from starting. Furthermore, this embodiment sets environment variables through the checksum results, effectively isolating the development / production environments and further ensuring the security of the vehicle's infotainment system.

Finally, it sets environment variables based on the verification result through a login verification module, and completes login to the vehicle infotainment system based at least on the environment variables.

[0111] Therefore, this embodiment, on the one hand, generates a serial configuration file based on the chip serial number, and on the other hand, generates a standard configuration file based on the serial configuration file and the checksum. This enables a strong binding relationship between the configuration file and the vehicle's configuration chip, effectively preventing unauthorized devices from starting.
