Providing efficient measurable key by using unital based key predistribution scheme for wireless sensor networks

Resource limitations and potential WSNs application and key management are the challenging issues for WSNs.Network scalability is one of the important things in designing a key management scheme.So we are proposed a new scalable key management scheme for WSNs; by this we will achieve a good secure connectivity.For this purpose we used one theory that is called Unital design theory.We have to show mapping from unital to key pre-distribution, by this mapping we will achieved high network scalability and sharing probability.So, that they have extended their work still more by finding another theory that is Unital based key pre-distribution scheme, by using this they achieved high network scalability and sharing probability.They had conducted some of the analysis and simulation and the results had been compared with that of the existing system, by using different criteria such as, 1. Storage overhead 2. Network scalability 3. Network connectivity 4. Average secure path length 5. Network resiliency So, the system had shown good network scalability and sharing probability.
