Problems solved by technology

However, the beam of the phased array is only related to the direction and has no effect on the distance
Therefore, it can only bring system security in the direction dimension.

Embodiment

[0074] see figure 2 , the present invention is based on the system safety performance evaluation method of FDA's disguise and deception, comprising the following steps:

[0075] Step 1: Use the carrier frequency of a certain element of the FDA antenna as the reference carrier frequency, and add different frequency offsets to the carrier frequency of other elements, and then transmit the signal carrying information through the FDA antenna go out.

[0076] In this step, the FDA antenna adopts a uniform linear FDA antenna, such as image 3 As shown, and the first element of the antenna array is used as the reference element. In this way, the transmitted signal of the nth antenna element is expressed as:

[0077]

[0078] Among them, P S is the total transmission power of the signal transmitter; is the transmitted confidential information symbol; f n = f 0 +nΔf is the transmitting frequency of the nth antenna element; t represents time; N is the total number of antenna...

Abstract

The invention relates to physical layer information security technology of wireless communication. The invention discloses a system safety performance evaluation method based on FDA camouflage and deception, comprising the following steps: Step 1: taking the carrier frequency of a certain array element of the FDA antenna as the reference carrier frequency, and the carrier frequency of other array elements as the reference carrier frequency Add different frequency offsets on the basis of the carrier frequency, and then transmit the signal carrying information through the FDA antenna; Step 2: The legal user D designs its signal receiver according to the characteristics of the signal transmitter, and performs information analysis on the received signal step 3: eavesdropping user E judges the signal received by its receiver, and uses OFDM signal processing method according to the characteristics of the received signal to demodulate the received signal; step 4: calculate according to step 2 and step 3 respectively The receiving signal-to-noise ratio of legitimate users and eavesdropping users is calculated, and then the safe transmission rate of the system is calculated to evaluate the system security performance. The invention ensures the safe transmission of information.

Description

technical field [0001] The present invention relates to the physical layer information security technology of wireless communication, in particular to the technology of misleading the eavesdropping user's information reception according to the characteristics of the signal transmitted by the frequency control array antenna, and enhancing the security communication performance of the system, specifically the system security performance based on FDA camouflage and deception assessment method. Background technique [0002] The openness of the wireless communication channel makes the transmitted confidential information easily intercepted by eavesdroppers. At the same time, the continuous increase of cybercrime incidents on mobile terminals has also exposed the huge hidden dangers of information security in wireless communication networks. Therefore, information security issues have attracted much attention. [0003] Traditional encryption technology only provides computationa...
