A wireless networks of thousands of
inexpensive miniature devices capable of computation, communication and sensing
their use throughout society “could well dwarf previous milestones in the
information revolution” .It Provide a bridge between the real physical and
virtual worlds. A new scalable key management scheme forWSNs which provides
good secure connectivity coverage. For this purpose, we make use of the unital
design theory. Allow the ability to
observe the previously unobservable at a fine resolution over large
spatio-temporal scales. Have a wide
range of potential applications to industry, science, transportation, civil
infrastructure, and security. Our scheme exhibits a nice threshold property:
when the number of compromised nodes is less than the threshold, the
probability that any node other than these compromised nodes is affected is
close to zero. This desirable property lowers the initial payoff of smaller
scale network breaches to an adversary, and makes it necessary for the
adversary to attack a significant proportion of the network..Sensor networks
are being deployed for a wide variety of applications, including military
sensing and tracking, environment monitoring, patient monitoring and tracking,
smart environments.Key pre distribution is an important topic that constitutes
the basis of security in wireless sensor networks. Many security mechanisms
such as encryption and authentication can be provided by accessing to shared
keys. Several techniques are Key pre distribution is an important topic that

issue. Previously proposed to address this issue.
