REMOTE DEBUGGING FOR THE INTERNET OF THINGS

Abstract: an internet of things (iot) device is deployed with embedded software. a debug client device stores an end-to-end encryption key that corresponds to an end-to-end encryption key stored on the iot device. the debug client encrypts a debug instruction using the end-to-end encryption key and encrypts additional data using a point-to-point encryption key. the encrypted debug instruction and the encrypted additional data are sent to a debug server over a network. the debug server decrypts the additional data and identifies the iot device from among multiple iot devices. the debug server generates a message to the iot device including the encrypted debug instruction, encrypts the message, and transmits the message to the iot device. the iot device decrypts the message using a first decryption key associated with the debug server, retrieves the encrypted message payload, and decrypts the message payload using the stored end-to-end encryption key.
