Abstract

The invention provides a detection method, applied to an electronic device. The method comprises the following steps: acquiring an audio signal; analyzing the audio signal, thus obtaining energy distribution features; based on the energy distribution features and standard energy distribution features, determining that whether audio side channel attack aiming at the electronic device exists or not, wherein the standard energy distribution features are energy distribution features shown by the audio signal of the electronic device when the audio side channel attack aiming at the electronic device does not exist. The invention further provides a detection device, the electronic device and a computer readable storage medium.

Description

technical field [0001] The present disclosure relates to a detection method, a detection device, electronic equipment and a computer-readable medium. Background technique [0002] In the past few years, the processing power, operating system, networking function and sensor accuracy of intelligent electronic devices have been greatly improved, but while improving the device performance and user experience, it has also increased the vulnerability of the system. [0003] Audio side-channel attack is a new technology developed recently. By mixing attack codes in the application program to control the speaker and microphone of the electronic device, a miniature smart sonar is formed to track the behavior and operation of the user, making the electronic device Reduced device security. [0004] However, timely detection of audio side-channel attacks on electronic devices has always been a difficult problem in the industry. Contents of the invention [0005] One aspect of the pr...
