Anonymous Broadcast Authentication With One-to-Many Transmission to Control IoT Devices

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