Embodiment
[0063] An anti-active eavesdropping physical layer security technology based on orthogonal characteristic parameter authentication is applicable to the OFDM-QPSK system, and OFDM uses K subcarriers. System model such as figure 1 As shown, there are three nodes: the source node Alice, the legitimate receiving node Bob, and the eavesdropping node Eve, which are abbreviated as A, B, and E respectively in the following. There is a two-way wireless connection between Alice and Bob, and there is also a two-way wireless connection between Alice and Eve; and the distance between Bob and Eve is far away, there is no direct path, and they cannot listen to the signals sent by each other. The two-way transmission between any pair of nodes adopts time-division duplex mode. The transmission from Alice to Bob within a time slot is divided into two phases. The length of the first stage is T 1 , the length of the second stage is T 2 , satisfying T=T 1 +T 2 .

The present application belongs to the technical field of wireless communication, and in particular relates to an anti-active eavesdropping physical layer secure transmission method of the Industrial Internet of Things. The traditional physical layer security transmission scheme is only for passive eavesdropping. Once the eavesdropper obtains the key, the eavesdropper can eavesdrop without being discovered by legitimate users; and it is not effective in dealing with active eavesdropping attacks. This application provides an anti-active eavesdropping physical layer security transmission method of the Industrial Internet of Things, including: initiated by a legal receiving node, orthogonal encryption and distribution of security parameters; authentication of orthogonal characteristic parameters, so that the source node restores security parameters; Initiated by the source node, the security parameter is encrypted for data transmission; the legitimate receiving node completes the recovery of the data. Ensure that eavesdroppers cannot obtain data information through passive eavesdropping and active deception.
Description
technical field [0001] The present application belongs to the technical field of wireless communication, and in particular relates to an anti-active eavesdropping physical layer secure transmission method of the Industrial Internet of Things. Background technique [0002] Due to the characteristics of open space, time-varying topology, and broadcasting characteristics of wireless communication systems, the communication is easy to be eavesdropped. The traditional cryptography encryption method that relies on computational complexity is facing elimination due to the continuous improvement of computer computing power. The physical layer security communication technology does not depend on computational complexity. At the same time, the computational overhead is small and the delay is short. Advantage. [0003] Someone proposed a physical layer authentication system for OFDM pilot signals based on independent check codes, and resisted spoofing attacks through interactive proto...
