COOPERATIVE TRANSMISSION SYSTEM FOR DETERMINING SECRECY RATE PREVENTING AVOIDING EAVESDROPPING BY EVE-NODE

摘要

Provided are a cooperative transmission system for determining an encryption rate for avoiding eavesdropping by an eavesdropping node and an operation method thereof. According to the present invention, the cooperative transmission system and the operation method thereof may reduce the likelihood of eavesdropping of an eavesdropping device without a repeater transmitting an intentional jamming signal in a network by determining a transmission encryption rate based on a transmission distance between the cooperative transmission system and a reception node and the number of cooperative nodes to be used for the cooperative transmission, transmitting data and the determined transmission encryption rate to first cooperative nodes, and allowing each of the first cooperative nodes to transmit the data to the reception node according to the determined transmission encryption rate.
