Abstract

“Security and Privacy are of special concern when a service request migrates across multiple domains such as in Cloud. The request and data may navigate across multiple networks (internet and mobile) and untrustworthy sites/service providers. Privacy need to be enforced such that if requested neither the identity of service provider nor the requestor is identified, the routing between is kept secure and privacy of data disseminated across cross domains is preserved.

I will focus on attacks on networks as a major theme. Since networks are vulnerable to attacks from users and malicious hosts, we need to develop monitoring schemes based on low cost probes that use only edge to edge measurements. Stripes and overlay-based schemes are used to infer delay and loss at egress routers and detect congestions and misbehaved flows due to Service Level Agreement (SLA) violations. Research results provide guidelines that allow in integrating schemes that can deal with intrusions and preserve QoS. Filters at ingress routers are used to block violating flows. In mobile ad hoc networks malicious attackers can prevent the integrity of the route establishment. The research challenge is to identify and isolate the attackers. A reverse Labeling Restriction (RLR) is presented to deal with malicious activity by attackers that might collude. Wormhole attacks, authentication, and privacy preserving data dissemination, anonymity of sender and receiver, identity management and wormhole attacks will be briefly discussed. This talk is based on joint work with hard working students at Purdue.”

Biography

Prof. Bharat Bhargava is a professor at Purdue since 1984. He built one of the first electronic medical care record systems in IU hospital. He has worked on reliability and integrity issues in distributed systems and has built several systems such as RAID (Reliable and Adaptable) and Promise (P2P). With Prof. Ramamoorthy and Kim, he founded the IEEE Symposium on Reliable Distributed Systems in 1981, with Prof. Adam and Yesha, he founded the Digital Library conference in 1990 and the conference on Knowledge and Information Management in 1992. He is a fellow of IEEE and has received the technical achievement award, golden core award, and distinguished service award from computer society. He is a fellow of Institute of Electrical and Telecommunication Engineers (IETE) and fellow of CERIAS security center. His passion is to advance the career of all students and specially minority students. He is using the cloud technology to assist blind and hearing impaired persons. At Purdue he has been inducted in the book of great teachers and his name is engraved on a display in Purdue Union. He has received the graduate mentoring, engagement award, and diversity awards from College of Science.More information is available at http://www.cs.purdue.edu/people/bb.
