INTRODUCTION

In wireless sensor network collecting data from sensor node is complex process because attacker can compromise the network easily q-composite key pre-distribution techniques used in existing techniques.

If attacker captures fraction of nodes than he will compromise .

Here we are going to strength the authentication mechanism by three tier security scheme.

Blundo scheme provides clear security guarantee in wireless sensor networks and having polynomial pools.

Here attacker compromising network is complex because he have to get at least one polynomial from mobile pool.

A wireless sensor network (WSN) of spatially distributed  autonomous sensor to monitor physical or environmental conditions, such as temperature, sound, pressure, etc.

WSN

MOBILE SINK Mobile sink are vital in many WSN application

for efficient data accumulation for distinguishing and revoking compromised sensors.

The problem of authentication and pairwise key establishment in sensor networks with is still not solved in the face of mobile sink replication attacks.

The problem with the basic:• probabilistic key pre-distribution scheme

-q-composite key pre-distribution schemes. -random pairwise keys scheme

Existing system and challenges

THE THREE-TIER SECURITY SCHEME

In the proposed scheme, we use two separate polynomial pools:

•The mobile polynomial pool

•The static polynomial pool.

Stationary access nodes, which will enable these mobile sinks to access the sensor network for data gathering.

Fig. The three-tier security scheme in WSN with mobile sinks.

The three-tier security scheme provides better network resilience and also provides pairwise key establishment.

To avoid Mobile sink replication attack they used the three tier security scheme.

Advantages

The three-tier security scheme more robust against a stationary access node replication attack

The authentication mechanism between the stationary access nodes and sensor nodes using one-way hashing algorithm.

Using two separate key pools and having few sensor nodes that carry keys from the mobile key pool.

we proposed a general three-tier security framework for authentication and pairwise key establishment between mobile sinks and sensor nodes.

conclusion

We have further improved the security performance of the proposed scheme against stationary access node replication attack by strengthening the authentication mechanism between stationary access nodes and sensor nodes.The proposed key distribution scheme reduces thecomputational cost in the nodes.

FUTURE SCOPE

Wireless sensor network promise exciting new applications in the near future.

WSN become more and more crucial to everyday life availability faults become less tolerable.

High availability of the nodes critical and must hold even under malicious conditions.
