SECURING DISTRIBUTED SYSTEMS UNDER CONTESTED ENVIRONMENTS

Bharat Bhargava, Purdue University

Abstract

This research presents solutions to Integrity, Security, Reliability and Confidentiality/Privacy of data and communication in distributed systems. The solution helps in providing right data at the right time to meet the mission requirements of the user. We identified ideas to make distributed systems continue operations under contested environments under threat of attacks (single or multiple/collusive) on communications and sites. We explored both wired and wireless communication. The ideas for graceful degradation, adapting to type, extent, duration and timing of attack to deal with anti-access and area denial problem. The challenges in contested environments is subdivided into two sets of complementary terms; Anti-Access and Area Denial. We proposed research solution for accomplishing design and objectives of PACE (Primary, Alternate, Contingency, and Emergency). Adaptability research to provide continuity of operations due to multiple network partitions or site failures is presented. Using ideas of active bundle (data and access privileges/policies) we ensure that data can only be accessed by persons with correct security clearance.

Biography

Bharat Bhargava is a professor of computer science at Purdue University. He is leading a Northrup Grumman sponsored consortium on Real Applications of Machine Learning (REALM) with MIT, CMU and Stanford.

He is contributing to Department of Defense on The Science of Artificial Intelligence and Learning for Open-world Novelty (SAIL-ON) and another project with NGC on explainable AI and adversarial machine learning.
