Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In addition, technical solutions between various embodiments may be combined with each other, but must be realized by a person skilled in the art, and when the technical solutions are contradictory or cannot be realized, such a combination should not be considered to exist, and is not within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating an authorization method of an embedded device according to a first embodiment of the present invention. In the embodiment of the invention, the authorization method of the embedded device comprises the following steps:
s101, acquiring information to be authorized of the embedded equipment;
s102, determining an authorization scheme for the embedded equipment according to the information to be authorized;
s103, authorizing the embedded device according to the authorization scheme.
Specifically, when the artificial intelligence algorithm is used for authorizing a plurality of embedded devices, the information to be authorized of the embedded devices is obtained. The information to be authorized comprises hardware resources of the embedded equipment, use occasions, different safety requirements, convenience of an authorization process and the like. It is understood that the above-mentioned information to be authorized can be set according to actual requirements, and is not limited herein. And then determining an authorization scheme for the embedded device according to the information to be authorized, wherein the authorization schemes in the scheme are three, namely a hardware encryption chip scheme, a single license scheme and a combination scheme of otp and license, and any authorization scheme can be used for independently authorizing each device. And finally, authorizing the embedded equipment according to the determined authorization scheme, so that the authorization requirements of different embedded equipment can be met, and the authorization flexibility and convenience are improved. The single license scheme, the otp and license combination scheme and the hardware encryption chip scheme have successively higher security level. It can be understood that, in the above scheme, the model file of the artificial intelligence algorithm is also encrypted, the current mainstream of the artificial intelligence algorithm is the deep learning algorithm, and the most valuable part of the deep learning algorithm is the model file obtained after the training of a large amount of data, so that the model file needs to be encrypted to prevent the equipment manufacturer from copying the model file. The above artificial intelligence algorithm is implanted by the intelligent algorithm company at the algorithm implantation end, and in the authorization, the intelligent algorithm company needs to provide sdk algorithm modules, wherein sdk comprises an algorithm library, a use document of the algorithm library, a corresponding tool, demo of the algorithm library and the like.
Further, when the authorization scheme is a hardware encryption chip scheme, the authorizing the embedded device according to the authorization scheme specifically includes:
acquiring the hardware encryption chip information;
analyzing the burning information in the hardware encryption chip to obtain authorization scheme information, wherein the authorization scheme information comprises an authorization time limit, an authorization algorithm function and an authorization algorithm resource; and
and authorizing the embedded equipment according to the authorization scheme information.
In this embodiment, when the hardware encryption chip scheme is adopted, the authorization date, the authorization function, and the authorized resources need to be written into the hardware encryption chip in advance, then the hardware encryption chip is externally connected to the embedded device, and after the algorithm module runs, the contents of the hardware encryption chip are read at regular time, so as to perform the relevant authorization. Considering that each embedded device needs to be externally connected with an encryption chip, the security is very high, the embedded device does not need to provide machine codes, and does not need to be imported by the license, the embedded device is convenient to use, and the cost of a hardware chip needs to be additionally increased. As described above, the hardware encryption chip can only write 1 time and read many times.
Referring to FIG. 2, FIG. 2 is a flowchart illustrating a single license scheme authorization method according to the present invention. In a specific embodiment, when the authorization scheme is a single opinion scheme, the authorizing the embedded device according to the authorization scheme specifically includes:
s201, acquiring a machine code of the embedded equipment;
s202, after receiving the license file generated by the encrypted machine code, importing the license file into the embedded device, and decrypting the license file; and
s203, authorizing the embedded device according to the decrypted license file.
In the embodiment, the obtained machine code is encrypted at the algorithm implantation end, the authorization time limit, the authorization algorithm function and the authorization algorithm resource are added to the encrypted data, secondary encryption is performed to form the authorization document file, and the authorization document file can be imported into the embedded device to be authorized. And the intelligent algorithm module on the embedded equipment decrypts the license file twice and authorizes the embedded equipment according to the license file decrypted twice.
Referring to FIG. 3, FIG. 3 is a flowchart illustrating a method for authorizing by the otp and conference combination scheme according to the present invention. Specifically, when the authorization scheme is a combination scheme of otp and conference, authorizing the embedded device according to the authorization scheme specifically includes:
s301, acquiring a machine code of the embedded equipment;
s302, after the encrypted machine code is written into otp resources, extracting the machine code of the embedded device to be authorized from otp resources;
s303, after receiving the license file generated according to the machine code of the embedded device to be authorized, importing the license file into the embedded device, and decrypting the license file; and
s304, authorizing the embedded device according to the decrypted license file.
Specifically, if the main chip provides otp resources, since otp has the characteristics of writing once and reading many times, the machine code is encrypted by a HASH algorithm (such as md5), the encrypted value is stored in otp resources, after the device is started, the algorithm module obtains the machine code of the device and encrypts the machine code by the same HASH algorithm, the obtained encrypted value is compared with the value read by otp, if the obtained encrypted value is the same as the value read by otp, the device is authorized, the algorithm can be normally used, otherwise, the algorithm cannot normally work. Considering that the HASH algorithm is an irreversible algorithm, the security is very high by using the otp authorization method, but the unique machine code of the device needs to be written otp, so that the aim of individually authorizing each device is fulfilled.
Specifically, the obtained machine code is encrypted at the algorithm embedding end, and the encrypted machine code can be written into otp resources. The encrypted data can increase the authorization time limit, the authorization algorithm function and the authorization algorithm resource, and carry out secondary encryption to form an authorization document file, and the authorization document file is imported into the embedded device to be authorized. After receiving the license file generated according to the machine code of the embedded device to be authorized, extracting the machine code of the embedded device to be authorized from the otp resource, importing the license file into the embedded device, decrypting the license file, and then authorizing the embedded device according to the decrypted license file.
Further, the acquiring the machine code of the embedded device specifically includes:
acquiring ID codes of main chips in a plurality of embedded devices;
determining whether the ID codes of the plurality of main chips are unique;
when the ID codes of the main chips are unique, the ID codes are used as machine codes of the embedded equipment;
and when at least two ID codes of the plurality of main chips are the same, the IP address or the mac address of the operation of the embedded equipment is used as the machine code of the embedded equipment.
In this embodiment, if the main chip can provide the ID code of the main chip and the ID codes of different main chips are different, the ID code of the main chip is used as the device machine code. If the main chip can not provide the ID code or the ID codes of different main chips are not unique, the IP address or the mac address of the embedded device can be used as the machine code considering that the IP address or the mac address of different devices in the operation process is unique.
Further, after decrypting the license file, the method further includes:
carrying out secondary decryption on the decryption result of the license file to obtain an authorized machine code;
comparing whether the authorized machine code is the same as the machine code of the embedded device;
and if the authorized machine code is the same as the machine code of the embedded device, authorizing the embedded device according to the decrypted license file.
Specifically, after decrypting the license file, obtaining an authorization time limit, an authorization function and an authorization algorithm resource, and performing secondary decryption on a decryption result of the license file to obtain an authorized machine code, comparing the authorized machine code with the machine code of the front equipment, if the authorized machine code is the same as the machine code of the front equipment, working according to the authorization time limit, the authorization function and the authorization resource, otherwise, working normally. If the simple license authorization is soft authorization, the method is used in the situation that the authorization level of the algorithm is not particularly high.
