Detailed Description
The present invention will be described in further detail with reference to specific embodiments in order to make the technical field better understand the scheme of the present invention. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
According to the kaleidoscope theory, a certain number of colored glass sheets are arranged in the kaleidoscope, the number and the quality of the fragments in the same kaleidoscope are not changed, and infinite new patterns and new designs can be formed only by rotating the kaleidoscope to enable the fragments to be newly combined. Therefore, the generation of random seeds can be performed according to this theory.
As shown in fig. 1, a random seed generating apparatus includes,
the application module is used for sending an application for acquiring the random seeds and sending the application to the kaleidoscope module;
the kaleidoscope module consists of a light-emitting source, kaleidoscope equipment, a picture collecting module and a sending module, and is started after receiving the application of the application module, the light-emitting source irradiates the kaleidoscope, and meanwhile, the kaleidoscope randomly rotates to generate pictures, the generated pictures are collected and obtained by the picture collecting module, and then the collected pictures are sent out by the sending module;
and the analysis module is used for acquiring the picture from the sending module and analyzing the received picture into the 16-system format content, wherein the acquired 16-system format content is the random seed.
The light-emitting light source is a composite light source composed of at least two lights with different colors, namely, the light-emitting light source is composed of at least two devices capable of emitting lights with different colors.
The kaleidoscope equipment of the kaleidoscope module is provided with glass fragments, the glass fragments are randomly placed once before being used every time, the number of the glass fragments placed every time is more than or equal to 2, and the glass fragments are taken out after being used every time.
The picture collecting module adopts a photosensitive element or a projection element, and when the luminous light source irradiates on the kaleidoscope device, the photosensitive element or the projection element collects and displays pictures formed in the kaleidoscope device.
In the invention, after visible light passes through the kaleidoscope, a static picture can be obtained, the 16-system format of the picture file is the generated random seed, and when a new seed is generated, the kaleidoscope only needs to be rotated to obtain a new picture as the new random seed.
The reason for generating data in the form of pictures is that the picture format includes a large amount of data, and besides the kaleidoscope picture, the picture format is also affected by the illumination during sampling, so that the randomness of the picture is increased, and the data length included in the picture format can meet the length requirement of most random seeds at present.
In order to increase randomness and non-repeatability, the glass fragments added into the kaleidoscope each time can be randomly screened, and each group of fragments is immediately destroyed after being used, so that the possibility of repetition of random seeds is basically eliminated. In addition, randomness can be increased through random rotation speed and rotation time, and actions such as vibration can be added to increase the random degree of distribution of the glass fragments in the kaleidoscope. Other means of increasing randomness based on this principle are included.
As shown in fig. 2, a method for generating random seeds, which generates random pictures by injecting a composite light source into a kaleidoscope as a mechanism for generating random seeds. Thereby effectively and simply generating the unrepeatable true random seeds with high randomness in a large quantity.
The realization process is as follows,
firstly, applying for obtaining random seeds through an application module;
secondly, after the kaleidoscope module receives the application information, the kaleidoscope module starts to rotate randomly and generates random pictures;
and thirdly, the analysis module analyzes the acquired random picture and analyzes the random picture into 16-system format content, wherein the acquired 16-system format content is the random seed.
And before the kaleidoscope module in the second step starts to rotate, automatically putting at least two pieces of glass fragments into kaleidoscope equipment, and enabling the kaleidoscope equipment to be matched with the kaleidoscope equipment to form random pictures.
The kaleidoscope module in the second step rotates randomly, namely, the rotation speed and the rotation time of kaleidoscope equipment are random, so that the acquired pictures are random in shape.
The kaleidoscope module is also provided with a vibration device, when the kaleidoscope device starts to rotate randomly, the vibration device is started and enables glass fragments in the kaleidoscope device to be randomly distributed, and the vibration device is made of a micro device comprising a micro vibration motor.
At present, most of the generation methods of random seeds adopt reproducible random seed generation such as system time or user actions, and due to the possibility of reproduction, the random seeds generated by the methods cannot completely ensure the safety of the random seeds. In the invention, visible light passes through the kaleidoscope, the data of the whole picture generated after the visible light passes through the kaleidoscope is acquired as random seeds, and then the random seeds can be reduced according to the requirement through an algorithm to reach the required random number length. According to the kaleidoscope principle, random seeds generated by the method can hardly reappear, the generated pictures provide a large amount of original random data, the requirements of various random values can be flexibly met, and the method can simply generate a large amount of true random seeds.
The present invention can be easily implemented by those skilled in the art from the above detailed description. It should be understood, however, that the intention is not to limit the invention to the particular embodiments described. On the basis of the disclosed embodiments, a person skilled in the art can combine different technical features at will, thereby implementing different technical solutions.
In addition to the technical features described in the specification, the technology is known to those skilled in the art.
