Pair-wise key establishment using Random Number & distinct random functions in WSNs

Abstract

Accomplishing Security in WSNs (Wireless Sensor Networks) is still untapped and is one of the very crucial tasks in field of Research & Development. WSNs constitute various resource-constrained sensor nodes which communicate among themselves through wireless links and have limited computational abilities, memory storage and physical capabilities. Exponential growth in field of intrusion and eavesdropping has lead to challenging task for secure communication. So paying heed on distributing keys among sensor nodes before establishing connection is the key issue. So this proposed paper has come up with a new robust key pre-distribution scheme using Random Prime Numbers & Functions which resolves threat without breaching security aspects. This new proposed mechanism has the power to achieve pair-wise keys between two sensor nodes using Algebraic, Exponential, Logarithmic and Discontinuous function with the key role of random prime number generation and functions which prevents eavesdroppers from performing security hacks. Thus it's very difficult to get spoofed.
