SUMMARY:Byzantine Multiple Access Channels
DESCRIPTION:Speaker: Neha Sangwan\n\nAbstract: \nWireless Internet of thing
 s (IoTs) consists of devices with varying levels of security connected ove
 r a shared communication medium. This can allow compromised devices to dev
 iate from the communication protocol and potentially disrupt the communica
 tion of other devices. The existing theoretical models of communication\, 
 for the most part\, assume users/devices which do not deviate maliciously 
 from the prescribed protocols. While attacks by external adversaries such 
 as jammers and eavesdroppers have been studied\, insider/ Byzantine attack
 s have not received much attention. This is precisely the form that attack
 s on IoTs take.  As a first step towards this\, we consider the uplink of 
 a network and model it using a  multiple access channel where users may de
 viate maliciously. In this talk\, we will investigate this model under dif
 ferent security guarantees: 1) When can honest devices communicate reliabl
 y even in the presence of malicious devices? 2) Is it possible to identify
  the malicious devices (when present) so that they can be taken offline? 3
 ) When is it possible to detect the presence of malicious devices (without
  necessarily identifying them)?\n\nThe talk is based on joint work with Ma
 yank Bakshi\, Bikash Kumar Dey and Vinod Prabhakaran.\n
