面向隐蔽通信系统的节点多维属性感知路由算法OA

Mainstream anonymous communication systems suffer from de-anonymization risks and inherent design limitations,making them in-sufficient to satisfy the covert communication requirements of specific authorized users.To address this issue,covert communication systems have therefore emerged.This paper investigates the centralized routing management requirements in covert communication systems and proposes a Multi-Attribute-Aware Routing Algorithm(MAARA).The zero-trust concept is introduced to construct a continuous node trust evaluation model.Based on this foundation,a multi-attribute-aware path generation mechanism is designed.Extensive simulation experiments demonstrate that the proposed algorithm can improve overall path performance and security while maintaining communication covertness.Furthermore,it en-ables flexible trade-offs between path preference and anonymity requirements.The proposed approach facilitates the fulfillment of high-security and high-reliability covert communication requirements for specific authorized users.
