Further\, CPS usually consists of multiple\nagents th at collaborate and share information with each other\, thus\nmaking them v ulnerable to privacy breach and leakage of confidential\ndata. This talk w ill focus on the need\, design and analysis of security\nand privacy mecha nisms in CPS.\n\nIn the first part of the talk\, we will present a securit y problem for\nreal-time resource-constrained autonomous systems (for exam ple\, a UAV)\,\nwhich can reserve only limited computational resources and time for\nsecurity and control purposes. In such scenarios\, the control and\nsecurity tasks usually compete with each other for limited resources and\nthere exists a trade-off between security and control performance. We \ncharacterise the optimal trade-off and identify attack regimes in which\ nthe system should prefer control tasks over security tasks\, and vice\nve rsa.\n\nThe second part will focus on privacy in cooperative dynamical\nmu lti-agent CPS. We present a noise adding differentially private\nmechanism to preserve the privacy of agents' state over time\, and\nanalyse the eff ect of the privacy mechanism on the system performance.\nNext\, we show th at a fundamental trade-off exists between privacy and\ncooperation level\, and it is beneficial for the agents to reduce\ncooperation if they want t o be more private.\n\nNew Delhi\, Delhi\, India LOCATION:New Delhi\, Delhi\, India ORGANIZER:shaunak.sen@ee.iitd.ac.in SEQUENCE:0 SUMMARY:[Legacy Report] SECURITY AND PRIVACY IN CYBER-PHYSICAL SYSTEMS URL;VALUE=URI:https://events.vtools.ieee.org/m/155206 X-ALT-DESC:Description: <br /><p>ABSTRACT:&nbsp\;Cyber-Physical&nbsp\;Syste ms&nbsp\;(CPS)&nbsp\;are&nbsp\;engineered&nbsp\;systems&nbsp\;resulting<br />from&nbsp\;a&nbsp\;seamless&nbsp\;integration&nbsp\;between&nbsp\;physi cal&nbsp\;processes&nbsp\;and&nbsp\;cyber<br />technologies&nbsp\;such&nbs p\;as&nbsp\;communication&nbsp\;networks&nbsp\;and&nbsp\;computational&nbs p\;hardware.<br />This&nbsp\;tight&nbsp\;integration&nbsp\;exposes&nbsp\;t he&nbsp\;CPS&nbsp\;to&nbsp\;a&nbsp\;variety&nbsp\;of&nbsp\;attacks\,&nbsp\ ;both&nbsp\;on<br />the&nbsp\;physical&nbsp\;and&nbsp\;cyber&nbsp\;compone nts\,&nbsp\;which&nbsp\;can&nbsp\;result&nbsp\;in&nbsp\;significant<br />p erformance&nbsp\;degradation.&nbsp\;Further\,&nbsp\;CPS&nbsp\;usually&nbsp \;consists&nbsp\;of&nbsp\;multiple<br />agents&nbsp\;that&nbsp\;collaborat e&nbsp\;and&nbsp\;share&nbsp\;information&nbsp\;with&nbsp\;each&nbsp\;othe r\,&nbsp\;thus<br />making&nbsp\;them&nbsp\;vulnerable&nbsp\;to&nbsp\;priv acy&nbsp\;breach&nbsp\;and&nbsp\;leakage&nbsp\;of&nbsp\;confidential<br /> data.&nbsp\;This&nbsp\;talk&nbsp\;will&nbsp\;focus&nbsp\;on&nbsp\;the&nbsp \;need\,&nbsp\;design&nbsp\;and&nbsp\;analysis&nbsp\;of&nbsp\;security<br />and&nbsp\;privacy&nbsp\;mechanisms&nbsp\;in&nbsp\;CPS.</p>\n<p>In&nbsp\; the&nbsp\;first&nbsp\;part&nbsp\;of&nbsp\;the&nbsp\;talk\,&nbsp\;we&nbsp\; will&nbsp\;present&nbsp\;a&nbsp\;security&nbsp\;problem&nbsp\;for<br />rea l-time&nbsp\;resource-constrained&nbsp\;autonomous&nbsp\;systems&nbsp\;(fo r&nbsp\;example\,&nbsp\;a&nbsp\;UAV)\,<br />which&nbsp\;can&nbsp\;reserve& nbsp\;only&nbsp\;limited&nbsp\;computational&nbsp\;resources&nbsp\;and&nbs p\;time&nbsp\;for<br />security&nbsp\;and&nbsp\;control&nbsp\;purposes.&nb sp\;In&nbsp\;such&nbsp\;scenarios\,&nbsp\;the&nbsp\;control&nbsp\;and<br / >security&nbsp\;tasks&nbsp\;usually&nbsp\;compete&nbsp\;with&nbsp\;each&nb sp\;other&nbsp\;for&nbsp\;limited&nbsp\;resources&nbsp\;and<br />there&nbs p\;exists&nbsp\;a&nbsp\;trade-off&nbsp\;between&nbsp\;security&nbsp\;and&n bsp\;control&nbsp\;performance.&nbsp\;We<br />characterise&nbsp\;the&nbsp\ ;optimal&nbsp\;trade-off&nbsp\;and&nbsp\;identify&nbsp\;attack&nbsp\;regim es&nbsp\;in&nbsp\;which<br />the&nbsp\;system&nbsp\;should&nbsp\;prefer&nb sp\;control&nbsp\;tasks&nbsp\;over&nbsp\;security&nbsp\;tasks\,&nbsp\;and& nbsp\;vice<br />versa.</p>\n<p>The&nbsp\;second&nbsp\;part&nbsp\;will&nbsp \;focus&nbsp\;on&nbsp\;privacy&nbsp\;in&nbsp\;cooperative&nbsp\;dynamical< br />multi-agent&nbsp\;CPS.&nbsp\;We&nbsp\;present&nbsp\;a&nbsp\;noise&nbs p\;adding&nbsp\;differentially&nbsp\;private<br />mechanism&nbsp\;to&nbsp\ ;preserve&nbsp\;the&nbsp\;privacy&nbsp\;of&nbsp\;agents'&nbsp\;state&nbsp\ ;over&nbsp\;time\,&nbsp\;and<br />analyse&nbsp\;the&nbsp\;effect&nbsp\;of& nbsp\;the&nbsp\;privacy&nbsp\;mechanism&nbsp\;on&nbsp\;the&nbsp\;system&nb sp\;performance.<br />Next\,&nbsp\;we&nbsp\;show&nbsp\;that&nbsp\;a&nbsp\; fundamental&nbsp\;trade-off&nbsp\;exists&nbsp\;between&nbsp\;privacy&nbsp\ ;and<br />cooperation&nbsp\;level\,&nbsp\;and&nbsp\;it&nbsp\;is&nbsp\;bene ficial&nbsp\;for&nbsp\;the&nbsp\;agents&nbsp\;to&nbsp\;reduce<br />coopera tion&nbsp\;if&nbsp\;they&nbsp\;want&nbsp\;to&nbsp\;be&nbsp\;more&nbsp\;pri vate.</p> END:VEVENT END:VCALENDAR
