Detailed Description
In order that those skilled in the art will better understand the present invention, a technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in which it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. 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.

Example 1
According to an embodiment of the present invention, there is provided a method embodiment of a key generation method, it should be noted that the steps shown in the flowchart of the drawings may be performed in a computer system such as a set of computer executable instructions, and that although a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in an order different from that shown or described herein.
Fig. 1 is a flowchart of a key generation method according to an embodiment of the present invention, as shown in fig. 1, the key generation method including the steps of:
step S102, dividing the fiber cross sections to obtain a plurality of sub-fiber cross sections.
In the above steps, as shown in fig. 2, the optical fiber cross section is uniformly divided into more than one area, and the optical fiber cross section may be divided into nine parts by using a well-shaped dividing method (as shown in fig. 2), or may be divided into nine parts by using a common dividing method such as a ring-shaped dividing method and a cross-shaped dividing method.
It should be noted that, the optical fiber cross section may be split unevenly by a predetermined method, so as to obtain illumination intensity data of multiple sub-optical fiber cross sections that are more convenient to process.
And step S104, acquiring the illumination intensity of the cross sections of the plurality of sub-optical fibers.
Optionally, in the above steps, the illumination intensities of the multiple areas (i.e., the sub-fiber cross sections) separated in each of the foregoing steps are obtained separately, so as to obtain an array of the illumination intensities refracted by one fiber cross section.
Step S106, the illumination intensity is processed by a predetermined algorithm to generate a target key.
It can be seen from the above that, in the embodiment of the present invention, the fiber cross sections may be divided to obtain a plurality of sub-fiber cross sections; then the illumination intensity of the cross sections of a plurality of sub-optical fibers can be obtained; finally, the illumination intensity may be processed using a predetermined algorithm to generate the target key. The key generation method provided by the embodiment of the invention achieves the purpose of generating the key by utilizing the randomness principle of the light intensities of the multiple sub-cross sections obtained by dividing the optical fiber cross section, thereby realizing the technical effect of improving the information security of the user account, and further solving the technical problem of reduced user information security caused by easy interpretation of the traditional encryption method in the related technology.
As an alternative embodiment, before dividing the fiber cross-section into a plurality of sub-fiber cross-sections, the method further comprises: and intercepting the target optical fiber to obtain the cross section of the optical fiber.
For example, the whole optical fiber may be physically cut by conventional means, and the cross section of the optical fiber may be obtained, where the cross section of the optical fiber may be irregular and uneven by the cutting by conventional means, so that the intensity of the light that is refracted out may have strong randomness.
In addition, the optical fiber section corresponding to the optical fiber cross section can be directly used as the optical fiber cross section near one end of the optical power meter.
FIG. 3 is a schematic illustration of an irregular cross-section of an optical fiber according to an embodiment of the present invention, as shown in FIG. 3, the cross-section of the optical fiber taken by conventional means is generally irregular, and its shape has a strong randomness, so that the key generated by subsequent processing is extremely difficult to crack.
As an alternative embodiment, obtaining illumination intensities of a plurality of sub-fiber cross-sections includes: triggering a predetermined light source to activate to emit a light beam toward the fiber cross-section; the method comprises the steps of receiving outgoing light beams of a plurality of sub-optical fiber cross sections by utilizing a light receiving device to obtain illumination intensity, wherein the light receiving device is positioned on the light output side of the optical fiber cross sections, the distance between the light receiving device and the optical fiber cross sections is a preset distance, and a preset light source is positioned on one side of the optical fiber cross sections away from the light receiving device.
Fig. 4 is a schematic view of an apparatus for acquiring illumination intensity according to an embodiment of the present invention, as shown in fig. 4, the other side of the cross section of the optical fiber to be refracted of the cut-out optical fiber section may be first irradiated with a light source at a fixed light intensity, and then an optical power meter (i.e., a light receiving device) is placed at a predetermined distance from the cross section of the optical fiber to receive the illumination intensity.
As an alternative embodiment, processing the illumination intensity with a predetermined algorithm to generate a target key includes: arranging the illumination intensities according to a preset strategy to obtain an array corresponding to the illumination intensities; the array is processed using a predetermined algorithm to obtain the target key.
In the above alternative embodiment, the obtained illumination intensities of the respective areas in the cross section of the optical fiber are first formed into an array, and then arranged according to the encryption requirement in a predetermined manner, where it should be noted that the predetermined manner may be a conventional arrangement method such as arrangement according to a preset area number, an ascending order of light intensity, or an arrangement according to a specific algorithm, and then the arranged array is processed by using the predetermined algorithm to generate the target key.
As an alternative embodiment, the predetermined algorithm comprises at least one of: hash algorithm, digital encryption RSA algorithm.
It should be noted that, the hash algorithm in the above embodiment may transform an input of any length (i.e., an array, a sequence, etc.) into an output of a fixed length (i.e., a target key) through the hash algorithm; the digital encryption RSA algorithm is an asymmetric encryption algorithm, and a target key can be generated through calculation by an array.
As an alternative embodiment, after processing the illumination intensity with a predetermined algorithm to generate the target key, the key generation method further includes: the light receiving device and the optical fiber cross section are subjected to a packaging process in a manner of being spaced apart by a predetermined distance.
In the above alternative embodiment, after the target key is generated, in order to save the target key, the fiber cross section of the outgoing light needs to be opposite to the optical power meter and placed in a manner of keeping a predetermined distance, then fixed and packaged, so that an accurate array is obtained again to generate and obtain the key.
It should be noted that, the predetermined distance is the same as the predetermined distance between the cross section of the optical fiber and the optical power meter when the illumination intensity is obtained, because the light intensity of the light refracted by the light attenuates with the distance in the air, if the distance changes, the illumination intensity changes, the initial array cannot be obtained, and the key cannot be generated, and because of this principle, the key generation method provided by the embodiment of the present invention has the advantages of being unable to copy and unable to crack.
As an alternative embodiment, after processing the illumination intensity with a predetermined algorithm to generate the target key, the key generation method further includes: and encrypting the target configuration file by using the target key, wherein the target configuration file is the configuration file corresponding to the equipment where the target optical fiber corresponding to the optical fiber cross section is located.
It can be known from the above that, in the embodiment of the invention, firstly, the hardware characteristics and the software functions are combined, the key is generated by utilizing the randomness of a plurality of factors such as the cross section of the optical fiber, the illumination intensity, the distance, the angle and the like, so that the uniqueness of each model machine key is ensured, the key cannot be obtained in a software decompiling mode, the distance between the cross section and the optical power meter, the rotation angle of the cross section in the catheter and the like are changed after the shell is disassembled (i.e. after the shell is contacted and packaged), and the original value of the key cannot be obtained, therefore, even if a single device key is cracked, the key has no universality, the security of other devices is not influenced, and the account information security of a user is improved.
