MUTUAL AUTHENTICATION AND ENCRYPTION KEY GENERATION IN WIRELESS AMBIENT POWER (AMP) DEVICES

Abstract: a method for receiving, by an ambient power (amp) device that harvests environmental energy, an identification (id) request frame from a powered wireless device. the id request frame includes one or more frame-exchange parameters and an authentication and key management (akm) method. the method includes retrieving, from memory, a secret that is shared with the powered wireless device, determining, using the secret, one or more first akm parameters, and transmitting, to the powered wireless device, by the amp device, an id response frame including an id of the amp device, at least one of the one or more frame-exchange parameters and the one or more akm parameters with which the powered wireless device is to be mutually authenticated with the amp device and to generate an encryption key to initiate an encrypted wireless communication session.
