This document summarizes three papers on security in wireless sensor networks. The first paper discusses problems in WSNs and the need to understand constraints like memory, power, communication and security requirements. While efforts have addressed key management, cryptography and DoS attacks, challenges remain around immediate node compromise detection. The second paper discusses WSN applications and proposes secure group management where nodes jointly track objects. The third paper focuses on architecting security solutions from the start given opportunities in early design stages, single administrative domains simplifying threats, and exploiting redundancy, scale and physical environment characteristics.

To many thought provoking
problems, Wireless Sensor
Networks have become a
feasible solution. However,the
deployment of new technology
without security has often
proved to be immoderately
dangerous. WSN have recently
attracted a lot of interest to the
researchers due to wide range
of applications.
In order to acquire useful
security mechanisms it is
mandatory to understand the
following constraints first-
Memory and power
limitations, Unreliable
communication, and Security
requirements.
Although many efforts have been
made on key management
cryptography and defence against
DoS attack, some challenges are
still need to be addressed. The
current cryptographic mechanisms
detect and defend against node
compromise but there are still
some compromise activities that
cannot be detected immediately.

Secure group management. Each
node in a wireless sensor network
is limited in its computing and
com-munication capabilities.
However, interesting in-net-work
data aggregation and analysis can
be performed by groups of nodes.
For example, a group of nodes
might be responsible for jointly
tracking a vehicle through the
network.
First, we have the opportunity to
architect security solutions into these
systems from the outset, since they are
still in their early design and research
stages. Second, many applications are
likely to involve the deploy-ment of
sensor networks under a single
administra-tive domain, simplifying the
threat model. Third, it may be possible
to exploit redundancy, scale, and the
physical characteristics of the
environment in the
Solutions.
