Abstract

The embodiment of the present invention relates to a method, device and equipment for secure multi-hop data transmission based on power line communication, including obtaining channel state information and communication parameters of each communication channel on a multi-hop broadband power line, and constructing and communicating with each communication channel according to each communication parameter One-to-one corresponding channel transfer function, each communication parameter combined with the MK model to construct an actual channel model for each channel transfer function; establish a power line communication system model based on the actual channel model; input the joint transceiver matrix into the power line communication system model to obtain the objective function; The function uses an iterative distributed algorithm to optimize and solve, and obtains the safe rate of multi-hop data secure transmission on the power line communication system model; enables the power line to transmit data at a safe rate, ensures safe communication, and prevents eavesdropping users from stealing data. The technical problem of low security of data transmission under the multi-hop broadband power line communication system in the prior art is solved.

Description

technical field [0001] The present invention relates to the technical field of data transmission security, in particular to a multi-hop data security transmission method, device and equipment based on power line communication. Background technique [0002] Multi-hop broadband power line communication refers to the use of power lines as the medium of signal transmission. When sending signals, the modulation technology is used to modulate the data, and the signal carrying information is loaded on the current, and then the power line is used for transmission; the signal is received at the receiving end At the same time, let the received signal pass through the filter first, then take out the modulated signal, and then pass through the demodulation technology to obtain the original communication signal, and transmit it to the telephone or computer to realize the transmission of information. [0003] At present, power lines have been distributed in every household, and the scope ...
