Problems solved by technology
For example, in the actual secure communication, the encryption system often adopts a three-dimensional chaotic system, and the real information is hidden in a certain dimension. If the calculation of the time-delay reserve pool is designed and implemented by a one-dimensional dynamic system, there will be a problem of mismatching the number of ports, which cannot Complete training and prediction

Embodiment Construction
[0019] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0020] Taking an image as an example, the standard size of the image is 200x200x3, and then arrange the image into a one-dimensional vector original signal h(t). In this embodiment, the Lorenz system is used for encryption verification.
[0021] Where the Lorenz equation is shown in equation (1):
[0022]
[0023] Where σ=10, γ=28, β=8 / 3.
[0024] First solve the equation (1), select the calculation step size dt=0.01s, and sample to get 3×10 5 data points U(t). Select the x dimension in U(t) as the driving signal, and the z dimension as the encryption signal, and scale the data to (0,1). Then divide U(t) into two parts, and set the first 6000 data points as the training set to U 1 (t), the rest of the data as encrypted data U 2 (t), first encrypt the signal h(t) to be sent, and the encryption equation is as follows:

According to the secure communication implementation method based on series time-delay based reservoir computing. A receiver synchronous decryption system is manufactured by using a method of multiple series time-delay based reservoir computing, the defect that a traditional receiver synchronous decryption system is limited by a sending end encryption system is overcome, and the flexibility of the decryption system is enhanced. A trained reservoir computing module can simulate and synchronize the encryption system through transmission of a scalar signal, learning and stable prediction of three-dimensional encryption system chaotic signals is achieved through one-dimensional time-delay based reservoir computing, and the problem of a three-dimensional data input port is solved. Through different-dimensional learning, chaotic synchronization is realized for the dimension, carrying real information, of the encryption system, so that decryption is realized. Only four real nodes and 48 virtual nodes are needed for series time-delay based reservoir computing, and the problems that a conventional reservoir is large in data size and difficult to achieve through hardware are solved. Finally, secrecy transmission of the image is realized through a chaos masking technology, and original information can be correctly and effectively recovered.
Description
technical field [0001] The invention relates to the interdisciplinary field of machine learning and chaotic secure communication, in particular to the synchronization of chaotic systems, and in particular to a method for implementing secure communication based on multiple time-delay reserve pool calculation series connections. Background technique [0002] Machine learning—reservoir computing can be used at the receiving end in chaotic secure communication, which can effectively remove the restrictions on the traditional receiving end decryption system settings. However, the traditional reserve pool calculation requires the use of a large number of actual nodes, which brings certain difficulties to hardware implementation. Time-delay based reservoir computing (Time-delay based reservoir computing), by using the nonlinear dynamic system to generate a time-delay feedback loop to form a virtual node, can effectively solve the difficult problem of traditional hardware implementa...
