    Abstract

    We consider a basic system to securely and remotely control many IoT devices. Specifically, we require that: (1) a system manager broadcasts information to IoT devices, e.g., wireless environment, only the designated devices can identify operations sent from the manager; (2) each IoT device can detect (malicious) manipulation of the broadcast information and hence prevents maliciously generated operations from being executed. In this paper, we introduce anonymous broadcast authentication (ABA) as a core cryptographic primitive of the basic remote-control system. Specifically, we formally define the syntax and security notions for ABA so that it achieves the above requirements. We then show provably-secure ABA constructions and their implementations to provide their practical performance. Our promising results show that the ABA constructions can remotely control devices over a typical wireless network within a second.
