N2 - Physical layer key generation (PLKG) is one of the promising security solutions for communications in the Internet of Things IoT. Among implementations for the PLKG, a low-cost, integrated, and portable design is still lacking. To this end, we build a cheap and moderately complex testbed with ESP32, which supports on-chip channel estimation. In the proposed testbed, four tasks are created to achieve channel probing and message exchanging for the PLKG. Considering independent clocks and packet mismatches in the real world, we implement a PLKG prototype that generates secret keys at a rate of 19.45 bit/s. Experimental results show that the generated keys can pass all commonly-used National Institute of Standards and Technology (NIST) randomness tests, and the transmitted information cannot be decrypted by the illegitimate user.
