Am I in Good Company? A Privacy-Protecting Protocol for Cooperating Ubiquitous Computing Devices

Abstract

A portable device carries important secrets in encrypted form; to unlock it, a threshold secret sharing scheme is used, requiring the presence of several other devices. We explore the design space for the protocol through which these devices communicate wirelessly, under the additional constraint that eavesdroppers should not be able to recognize and track the user carrying these devices.
