New Results on Unconditionally Secure Multireceiver Manual Authentication
Shuhong Wang and Reihaneh Safavi-Naini
Abstract
Manual authentication is a recently proposed model of communication motivated by the settings where the only trusted infrastructure is a low bandwidth authenticated channel, possibly realized by
the aid of a human, that connects the sender and the receiver who are
otherwise connected through an insecure channel and do not have any
shared key or public key infrastructure. A good example of such scenarios is pairing of devices in Bluetooth. Manual authentication systems
are studied in computational and information theoretic security model
and protocols with provable security have been proposed. In this paper
we extend the results in information theoretic model in two directions.
Firstly, we extend a single receiver scenario to multireceiver case where
the sender wants to authenticate the same message to a group of receivers. We show new attacks (compared to single receiver case) that
can launched in this model and demonstrate that the single receiver
