Produktbeschreibung
Based on recent technological advances,the
manufacturing of a large number of low cost wireless
sensors became technically and economically feasible.
Thousands of these sensors can be networked as a
wireless network for many applications that require
unattended,long-term operations. One of the critical
challenges to making sensor networks more pervasive
and secure is the severe resource constraints.This
dissertation explores specific security issues
associated with sensor networks through four related
themes. First,a taxonomy of security attacks and
countermeasures for sensor networks along with
methodologies for evaluation and design of secure
sensor networks is developed. The second theme
explores the issue of insider attacks on fundamental
services and applications in sensor networks. We look
at the time synchronization service and the object
tracking algorithm.Third theme deals with the
security issues facing the applications that use
sensor networks. The two important applications that
we look at are: health care systems, and the process
control systems.Fourth, we develop a game theoretic
framework to analyze and build a distributed
reputation mechanism for sensor networks.
