Abstract

The invention provides an information encryption optimization method for reducing transmission energy consumption, and specifically provides a novel security communication strategy suitable for a collaborative environment of multiple unmanned aerial vehicles, which optimizes the Kuznyechik encryption algorithm to reduce the transmission energy consumption, and belongs to the technical field of collaborative data security communication of multiple unmanned aerial vehicles. The method comprises the following steps: step 1: a key scheduling process: performing 32 times of Feistel structure function operation on a 256-bit master key to generate10 256-bit wheel keys; and step 2: data encryption process: executing 9 rounds of Kuznyechik encryption process in total, wherein each round comprises Stransform, L transform and modular two-plus operation on the corresponding wheel keys obtained in step 1, that is, input-K1-SL-K2-SL-...-K9-SL-K10-output. According to method of the invention, the multiplication table of the L transform operation process is mainly simplified, the calculation process is effectively reduced, the algorithms are reduced, the processing speed is improved, and the energy consumption of the unmanned aerial vehicles are reduced.

Description

technical field [0001] The present invention is an information encryption optimization method for reducing transmission energy consumption. Specifically, it is a new type of security communication strategy applicable to multi-UAV collaborative environment, through optimizing encryption algorithm, and then realizing the reduction of transmission energy consumption. The technical field of multi-UAV collaborative data security communication. Background technique [0002] UAVs have the advantages of lightness, convenience, low cost, and good concealment. They are very suitable for performing reconnaissance, search, rescue and other application tasks under obstructed or potentially dangerous complex conditions. However, when a single UAV performs a mission, it may be attacked by the external environment or limited by its own resources, and cannot complete the mission perfectly. The UAV swarm network composed of multiple UAVs can self-organize and perform detection, monitoring, r...
