海上复杂环境下的隐蔽通信技术综述OA

With the rapid development of wireless communication field and the continuous enrichment of information services,information security issues have also emerged.How to ensure the concealment of information in communication is receiving increas-ing attention.Covert communication is also known as low probability of detection(LPD)communication,it uses information hiding technology to prevent eavesdroppers from discovering communication signals,thus ensuring the covert transmission of information between both parties.This article provides a comprehensive introduction to civilian and military covert communication technologies,and proposes a covert communication scheme based on communication relay drones for complex marine environments.
