Projects Description
Secure
Mobile Systems (Funded by NSF, IBM)
Survivability
and secure communications are essential in a mobile computing environment. We
propose to conduct a series of experiments that will lead to the development of
new authentication and key management techniques for wireless communications.
We study the implementation of various authentication schemes on the overall
system performance. We propose a technique to achieve fault-tolerant mobile
node authentication in an efficient way. We will evaluate how various secure
group communication and access control techniques fit into the wireless world
by conducting scientific experiments in a systematic way.

Network
Security and Quality of Service (QoS) (Funded by ITR NSF, CERIAS, IBM)
We
are doing research on monitoring network domains to ensure that the domain is
not under attack by injecting execssive traffic or by violating service level agreements.
The objective of this research is make a domain safe and provide quality of
service to the users as it is agreed upon with the provider. For scalable
network monitoring, our focus is to develop monitoring schemes that do not
involve core routers in any measurement or poll the core routers for delay,
loss, or bandwidth parameters. The misbehaving flows are detected and
controlled by activating filters and shapers. Security is treated as a Quality
of Service (QoS) parameter. Traffic Conditioner (TC) is an important part of
Differentiated Services (DiffServ) networks. TC marks packets as IN or OUT
profile or set the drop precedence. Based on this core routers give services to
packets. There are several techniques for conditioning. TCP is a very conservative
protocol and we can utilize some of it's features to develop a good TC. TC also
should consider the current measured rate and target rate of an aggregated flow
to set drop precedence. We explore several ideas to improve the performance of
existing TC.

Web
and Data Warehousing Security (Funded by CERIAS)
Data
warehouse is an integrated repository derived from multiple source (operational
and legacy) databases. The data warehouse is created by either replicating the
different source data or transforming them to new representation. This process
involves reading, cleaning, aggregating and storing the data in the warehouse
model. The software tools are used to access the warehouse for strategic
analysis, decision-making, marketing types of applications. It can be used for
inventory control of shelf stock in many departmental stores.
We focus on the
following ideas that can contribute towards warehouse security:
1. Replication control
2. Aggregation and Generalization
3. Exaggeration and Misleading
4. Anonymity
5. User Profile Based Security
This project aims at
developing and implementing efficient authorization and access control mechanisms
for web document and content of the document so that the legitimate users can
access the right data. We plan to investigate user identification,
authentication and access control as important security issue. Mechanisms
will be developed and implemented for both static and dynamic security.
