AI Technical Summary

Technical Problem

Existing air interface frame encryption technology cannot prevent eavesdroppers from continuously obtaining sensitive information from encrypted data packets, while eavesdropping coding technology is difficult to deploy in multi-user wireless networks, which allows eavesdroppers to continuously eavesdrop on the air interface frames of specific users and expose sensitive information.

Method used

By generating an air interface address that changes with the number of unicast transmissions, the sender of the air interface frame marks the air interface frame, and the receiver verifies the air interface frame using a preset verification method, ensuring that only legitimate receivers can obtain service data, and eavesdroppers cannot determine the identity of the receiver.

Benefits of technology

It effectively prevents eavesdroppers from discovering the identity of the sender or receiver of the air interface frame, protecting communication privacy and preventing the leakage of sensitive information.

Abstract

Embodiments of the present application provide a unicast transmission method and system based on an air interface frame, electronic equipment and a storage medium, relating to the technical field of information security. The method comprises: a network device responding to a network access request initiated by a terminal, so that the network device and the terminal both obtain an initial air interface address; a sending end of the air interface frame generating an air interface address that changes with the number of unicast transmissions, marking the air interface frame according to the air interface address, and unicasting the marked air interface frame to a receiving end of the air interface frame; the receiving end of the air interface frame verifying the received air interface frame according to a preset verification method, and obtaining service data in the air interface frame after the verification is passed. The embodiments of the present application can effectively prevent an eavesdropper from eavesdropping the identity of the sending end or the receiving end of the air interface frame.
