In a large sensor network of 1024 nodes, 32 clusters are formed, with each cluster consisting of 32 nodes. Each CH employees 32x32 2-D matrix based secured symmetric keys to communicate with each member of the cluster; while 32x32 2-D matrix based bivariate polynomils to communicate among the CHs? Is this a feasible solution to provide increasing level of security based on criticality of data? Explain clearly.
What will be an ideal response?
Data at each CH is more critical than sensor devices and hence deserves higher level of security provided by the bivariate polynomial. Therefore, the use of different key approach for the system is desirable.
