Abstract

The invention discloses a secret communication method based on double-end deployment multi-layer time-delay reserve pool calculation, which comprises the following steps of: simultaneously deploying a time-delay reserve pool calculation model formed by a plurality of series-connected time-delay reserve pools to a receiving end and a sending end, and simultaneously training the time-delay reserve pool calculation models of the receiving end and the sending end by adopting a training set L (t); the sending end chaotic system continuously generates a new chaotic signal, the Ux (t) is reserved as a drive set to drive the time-delay reserve pool calculation model of the sending end to obtain a chaotic sequence Uz (t) for encryption, and meanwhile, the Ux (t) is sent to the time-delay reserve pool calculation model of the receiving end to synchronously generate a chaotic sequence for decryption consistent with the Uz (t); the sending end encrypts communication data to be transmitted by adopting the chaos sequence for encryption; and the receiving end decrypts the received encrypted communication data by adopting the chaotic sequence for decryption. According to the invention, high-quality chaos synchronization of the transmitting end and the receiving end can be realized, so that transmitted useful information can be stably demodulated.

Description

technical field [0001] The invention relates to the cross-technical field of machine learning and chaotic secure communication, in particular to a secure communication method based on dual-end deployment and multi-layer time-delay reserve pool calculation. Background technique [0002] The core of chaotic secure communication lies in the chaotic synchronization between encryption system and decryption system. In the traditional mechanism, the transmitter and the receiver generally need to configure the chaotic dynamic system separately, and through the design of the coupling mechanism, the chaos synchronization is realized, so as to demodulate the useful information transmitted. However, the traditional mechanism has the following disadvantages: 1. The selection of the encryption system and the security system is not flexible. Once implemented in hardware, it is difficult to replace it at low cost; 2. The implementation of the coupling mechanism is relatively complicated, an...
