Summary: | The invention relates to the technical field of wireless channel keys, in particular to a physical layer key generation method, device and system, computer equipment and a medium. The method comprises the following steps: performing signal interaction with a second communication end based on channel reciprocity to generate an initial key; receiving encrypted data after the second communication end encrypts the signal interaction data by using the initial key; calculating a difference value between data obtained by decrypting the encrypted data and subcarriers with different serial numbers in the signal interaction data, encrypting a serial number corresponding to the difference value meeting a preset condition by adopting an initial key, and then sending the serial number to a second communication end; and negotiating based on the subcarrier difference value corresponding to the serial number meeting the preset condition and a subcarrier difference value generated after the second communication end decrypts a |
