Physical layer security modulation method and device, electronic equipment and storage medium

Abstract

The embodiment of the invention provides a physical layer security modulation method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining to-be-sent target information; decomposing the target information into two paths of orthogonal modulation information; for each path of modulation information, determining a plurality of preset channels for sendingthe path of modulation information; For each path of modulation information, adjusting the modulation information through the adjustment parameters of each preset channel of the modulation information to obtain target modulation information corresponding to each preset channel; and for each path of target modulation information, sending the target modulation information through a preset channel corresponding to the target modulation information, so that a target information receiving end obtains the target information according to the received target modulation information. Based on physicallayer safety communication, the method does not depend on a secret key and an algorithm in the information sending process, equivalently, a signal source of an eavesdropper is directly cut off, and therefore the communication mode of the method has better anti-interception performance.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a physical layer security modulation method, device, electronic equipment and storage medium. Background technique [0002] The purpose of communication is to safely and quickly transmit information from the sending end to the receiving end through channels. Due to the limitation of the channel, the information must be modulated to a certain frequency band before it can be transmitted, so the appropriate modulation mode becomes an important factor affecting the communication quality. [0003] Due to the open wireless medium, security is an important issue in wireless networks. In order to improve the security of the information sending process, in the prior art, usually at a higher network layer, the sending information of the information sending end is encrypted by an encryption algorithm, and sent to the information receiving end, so as to prevent eavesdroppers ...

Problems solved by technology

[0004] However, the inventor found that in the way of using encryption algorithms in the prior art, since the encryption technology depends on the length of the secret key and the complexity of the algorithm, if the length of the secret key and the complexity of the algorithm are increased, the system overhead will be very high
