Apparatuses and communication methods of key generation

A wireless communication method of key generation by a base station, comprising:

• performing a physical layer key generation with a user equipment that has obtained sensor data from a non-3GPP sensor coupled to a target object, wherein the sensor data comprises medical information about the target object;
• obtaining cryptographic information based on the physical layer key generation;
• transmitting a 5G reflected-sensing signal to the target object;
• and
• receiving an encrypted packet from a user equipment, wherein the encrypted packet comprises the sensor data and the reflected-sensing signal, wherein the sensor data and reflected-sensing signal are combined and encrypted together using the cryptographic information;
• wherein the wireless communication method further comprises:
• processing the encrypted packet using the cryptographic information to obtain a combination of the sensor data and the reflected-sensing signal.

A user equipment, comprising:

• a memory;
• a transceiver;
• and
• a processor coupled to the memory and the transceiver;
• wherein the user equipment is configured to perform:
• obtaining sensor data from a non-3GPP sensor coupled to a target object, wherein the sensor data comprises medical information about the target object:
• performing a physical layer key generation with a base station;
• obtaining cryptographic information based on the key generation;
• receiving a 5G reflected-sensing signal from the target object;
• combining the reflected-sensing signal and the sensor data;
• encrypting the sensor data and the reflected-sensing signal using the cryptographic information to generate an encrypted packet;
• and
• transmitting the encrypted packet to the base station;
• wherein encrypting the sensor data and the reflected-sensing signal using the cryptographic information to generate the encrypted packet comprises:
• encrypting a combination of the reflected-sensing signal and the sensor data using the cryptographic information to generate the encrypted packet, wherein the encrypted packet comprises the combination of the reflected-sensing signal and the sensor data.
