All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, shall fall within the scope of the present invention.
It should be noted that the terms "first," "second," and the like in the description and the claims of the present invention and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Fig. 1 is a flowchart of a radar starting method according to an embodiment of the present invention, where the method may be applied to a case of controlling radar firmware to operate a radar, where the method may be performed by a radar starting apparatus, where the radar starting apparatus may be implemented in hardware and/or software, where the radar starting apparatus may be configured in any electronic device having a network communication function, where the electronic device may be a radar device, such as a millimeter wave radar, and the like. As shown in fig. 1, the radar starting method of the present embodiment may include the following processes:
s110, determining a target machine code ciphertext from target radar firmware, wherein the target machine code is generated by encrypting and hashing according to a preset hardware serial number of the target radar.
The radar firmware refers to a radar driving program stored in the radar, and specific operation logic can be realized only through the radar firmware. Referring to fig. 2, the radar firmware may include three parts, a boot program, a key, and an executable main program. For the preset hardware serial number of the target radar, the preset hardware serial number of the target radar can be encrypted and hashed in advance to generate a target machine code, and the generated target machine code ciphertext is stored in the target radar firmware. The machine code may be a serial number formed by encrypting and hashing a hardware serial number.
Alternatively, the preset hardware serial number may be one or a combination of a hard disk serial number of the target radar and a chip serial number of the radar chip. For example, the preset hardware serial number may be a chip ID of a radar chip in the target radar, a hard disk ID in the target radar, or other hardware unique identifiers, and in order to increase complexity of the machine code, the hard disk serial number and the chip serial number of the radar chip may be combined to be used as the preset hardware serial number, so as to encrypt and hash the machine code.
Optionally, the target machine code is obtained by performing confusion processing on a preset hardware serial number of the target radar and a salt value given to the target radar in random generation, and the salt values adopted when different radars generate the machine code are different. Or the target machine code is obtained by carrying out preset hash processing on a preset hardware serial number of the target radar.
And randomly generating a salt value corresponding to each target radar aiming at each target radar, wherein each radar has different salt values, and acquiring a preset hardware serial number of the target radar, wherein the length of the salt value of the target radar is kept the same as that of the preset hardware serial number adopted when the target radar generates a machine code. And carrying out confusion processing on the preset hardware serial number of the target radar and the salt value given by the random generation of the target radar to obtain a target machine code corresponding to the target radar which is randomly generated.
Illustratively, a simple confusion approach is provided for target radars: the radar chip ID in the target radar is 123456789, the salt value randomly generated by aiming at the target radar is abcdefghi, and the machine code obtained after confusion is 1a2b3c4d5e6f7g8h9i.
Optionally, as the method for confusing the hardware serial number and the salt value is changeable, on the premise of no leakage, an attacker cannot forge the machine code, namely cannot forge the machine code on a new radar device, thereby achieving the function of spoofing the bootstrap program, and therefore, the confusing mode adopted in the generation of the target radar machine code can be encrypted, and the leakage of the target radar machine code is avoided as much as possible.
Optionally, determining the target machine code ciphertext from the target radar firmware includes: starting a bootstrap program in the target radar firmware; and loading the target machine code ciphertext into the secret key of the target radar firmware through a bootstrap program.
Referring to fig. 2, for a target radar, a key pair (such as an RSA key pair) used by the target radar may be generated in advance, and each radar may generate one or more sets of key pairs, but it is necessary to ensure that encryption and decryption are used with the same set of key pairs. For the target machine code plaintext of the target radar generated in advance, the target machine code plaintext can be encrypted by using a public key in a pre-generated key pair, and the encrypted target machine code ciphertext is stored in a key of the target radar firmware, for example, in a 0x8000-0x8100 space of the radar firmware.
Referring to fig. 2, the function of the boot strap in the radar firmware is to load and decrypt the encrypted executable main program, complete the hardware verification, and boot the main program to start. Therefore, when loading the target machine code ciphertext, it is necessary to first start the boot program in the target radar firmware, acquire the target machine code ciphertext from the key of the target radar firmware through the boot program, and load the acquired target machine code ciphertext through the boot program.
S120, decrypting the target machine code ciphertext to obtain a target machine code plaintext, and extracting a first hardware serial number from the target machine code plaintext.
Optionally, decrypting the target machine code ciphertext to obtain the target machine code plaintext includes: loading a preset private key associated with a target machine code ciphertext from a security chip of a target radar; and decrypting the target machine code ciphertext by adopting a preset private key associated with the target machine code ciphertext to obtain a target machine code plaintext, wherein the target machine code ciphertext is obtained by encrypting the target machine code plaintext by adopting a public key in a public-private key pair to which the preset private key belongs.
The preset private key associated with the target machine code ciphertext can be stored in the designated storage space, and the private key is stored in the security chip associated with the target radar for enhancing the security. Meanwhile, the public key in the public-private key pair to which the preset private key belongs can be adopted to encrypt the target machine code plaintext to obtain the target machine code ciphertext. The private key exists in the security chip and cannot be read maliciously, so that an attacker cannot decrypt the machine code without actively revealing the private key.
Optionally, extracting the first hardware serial number from the plaintext of the target machine code includes: reversely extracting a hardware serial number which is confused with the target machine code plaintext from the target machine code plaintext according to a confusion mode adopted when the target machine code plaintext is generated; the reverse extracted hardware serial number is determined as the first hardware serial number.
S130, reading a second hardware serial number from a hardware serial number memory of the target radar.
The first hardware serial number is a serial number which is encrypted and hashed and hidden in the machine code based on a preset hardware serial number of the target radar in advance, and the second hardware serial number is a preset hardware serial number of the radar stored in the target radar register. In the case where the target radar firmware of the target radar is not copied to the target radar, the hardware serial number hidden in the machine code stored in the target radar firmware should be identical to the hardware serial number in the register of the target radar, and if not identical, it is likely that the target radar firmware in the target radar is copied from other radars.
And S140, starting and controlling the target radar according to the first hardware serial number and the second hardware serial number.
Optionally, performing start control on the target radar according to the first hardware serial number and the second hardware serial number may include the following steps A1-A2:
and A1, comparing the first hardware serial number with the second hardware serial number.
And step A2, if the first hardware serial number is the same as the second hardware serial number, decrypting the encrypted executable main program in the target radar firmware by adopting a target machine code plaintext, and loading and starting the decrypted executable main program in the target radar so as to start the target radar.
And step A3, if the first hardware serial number is different from the second hardware serial number, performing damage to the encrypted executable main program so as to inhibit the starting of the target radar.
Referring to fig. 2, a target machine code stored in a key of a target radar firmware may be used as an encryption key, and the target machine code may be used as the encryption key to encrypt (e.g., AES encrypt) a key executable main program of the target radar firmware, to obtain an encrypted executable main program. Because the machine code of each radar is different, the resulting encrypted executable main program is also different.
Referring to fig. 2 and 3, the boot program starts, the machine code ciphertext is loaded from the 0x8000 location of the target radar firmware, and the RSA private key is read from the security chip. And (3) using an RSA private key to secret the machine ciphertext to obtain a machine code plaintext, wherein the machine code plaintext is formed by mixing a hardware serial number of a radar chip with a salt value, and reversely extracting the hardware serial number of the chip according to a mixing method. The chip unique hardware serial number is read and compared with the chip serial number extracted from the machine code plaintext. If the machine code is the same, the machine code is used for decrypting the main program, and the main program is started in a jumping mode, so that the equipment is started safely. If not, the secure boot fails, entering a self-destruction process. Self-destruction may be the deletion of the main program or the destruction of the main program by means of contaminated data.
According to the technical scheme, a target machine code ciphertext is determined from target radar firmware, and the target machine code ciphertext is generated by encryption and hash according to a preset hardware serial number of a target radar; decrypting the target machine code ciphertext to obtain a target machine code plaintext, extracting a first hardware serial number from the target machine code plaintext, reading a second hardware serial number from a hardware serial number memory of the target radar, and further performing starting control on the target radar through the first hardware serial number and the second hardware serial number, wherein even if radar hardware is plagiarized, radar firmware is copied to a piece of repeated radar hardware, because the hardware serial number cannot be resolved from the machine code of the radar, the radar cannot pass verification when the executable main program needs to be operated, and therefore the radar cannot be started normally, and moreover, the difficulty of forging the machine code is high, so that the radar firmware can be effectively prevented from being copied to another radar device to operate the main program.
