As the number of Internet of things devices increases, there is a growing importance of securely managing and storing the secret and private keys in these devices. Public-key cryptosystems or symmetric encryption algorithms both use special keys that need to be kept secret from other peers in the network. Additionally, ensuring the integrity of the installed application firmware of these devices is another security problem. In this study, private key storage methods are explained in general. Also, ESP32-S2 device is used for experimental case study for its robust built-in trusted platform module. Secure boot and flash encryption functionalities of ESP32-S2 device, which offers a solution to these security problems, are explained and tested in detail.
