Method for minimizing system confidentiality interruption probability using energy station

Abstract

The invention relates to a method for minimizing system confidentiality interruption probability using energy station, comprising: 1) transmitting by an energy station wireless energy to a source node prior to a Theta T time wherein theta represents a time allocation factor ranging from zero (not included) and one (not included) and T represents a time slot; 2) estimating the channel state information of a communication system by the energy station through the listening of the pilot frequencies at the source node, a legal receiving node and an eavesdropping receiving node; through the utilization of the estimated and obtained channel state information, designing a corresponding best beam former w2 by the energy station; 4) in the coming (1-theta)T time, transmitting by the source node the wireless signals to the legal receiving node and eavesdropping by the eavesdropping receiving node the wireless signals; and using the beam former w2 by the energy station to transmit wireless interfering signals to the legal receiving node and the eavesdropping receiving node so as to minimize the system confidentiality interruption probability. According to the invention, an energy station is used to make the physical layers more secure, therefore, raising the confidentiality security performance of the entire communication system substantially.

Description

technical field [0001] The invention relates to the field of communications, in particular to a method for minimizing the system security interruption probability by using an energy station. Background technique [0002] With the rapid development of wireless communication technology, various wireless communication devices have increased dramatically, and the security problems of wireless communication have become increasingly serious. The traditional wireless communication security mechanism is mainly related to encryption technology based on cryptography, but with the rapid improvement of computer computing power, the confidentiality foundation of this technology has become unreliable, and physical layer security technology has emerged as the times require. [0003] From the perspective of information theory, the physical layer security technology of wireless communication uses the uniqueness and reciprocity of physical channels to realize information encryption and identi...
