Embodiment Construction
[0028] Hereinafter, preferred embodiments of the present disclosure will be described in detail with reference to the drawings. In the following description, the same reference numerals are given to the same components, and repeated descriptions are omitted. In addition, the drawings are only schematic diagrams, and the ratio of dimensions between components, the shape of components, and the like may be different from the actual ones.
[0029] figure 1 is a schematic diagram showing a communication network model of a wireless energy transfer communication network involved in an example of the present disclosure. In some examples, such as figure 1 As shown, the base station can have one. Users can include at least one. The base station and each user are equipped with an antenna. In addition, the base station and all users work in the same frequency band. Attackers can include at least one.
[0030] In some examples, figure 1 In the signal model shown, a base station (su...

This disclosure describes a defense method for a wireless energy transmission communication network that damages the power supply system, including: the user sends a login request signal to the base station, the base station performs channel estimation, allocates corresponding transmission time periods for multiple users, and notifies the user of the allocation result; based on Channel estimation calculates the first credible throughput; in the process of broadcasting the distribution result, the attacker intercepts the distribution result and destroys the power supply system of the target user; when the first credible throughput reaches the first threshold required by the system, the base station broadcasts the energy signal, and the user Receive the energy signal and transmit the data signal within the corresponding transmission time period; the base station receives the data signal, calculates the safety interruption probability and the second credible throughput; monitors the second credible throughput of the target user, when the target user's second credible throughput If the throughput does not reach the second threshold required by the system, redistribute the transmission time period to reduce the transmission time period of the target user, so as to reduce the impact of the target user on the total throughput and improve the security of the entire system.
Description
technical field [0001] The present disclosure relates to the technical field of wireless communication, and in particular to a defense method and system for a wireless energy transmission communication network from damaging a power supply system. Background technique [0002] A wireless powered communication network (WPCN) is a communication network that obtains energy by collecting signals in the environment, and uses the obtained energy as an energy supply for a user end. [0003] In the existing literature, a mechanism has not been explicitly applied to satisfy certain security requirements of wireless energy transfer communication networks. For example, after the registration period, the AP (hybrid access point or base station, ie the transmitter) does not include an additional mechanism to verify the identity of the transmitter. Therefore, there are security holes in the wireless power transmission communication network (WPCN). [0004] In a wireless power transfer co...
