Pairwise Keys Generation Using Prime Number Function in Wireless Sensor Networks

Abstract —Providing security in wireless sensor networks is a very crucial task. Because of its dynamic nature (no fixed topology) and resource constraint devices. Which has limited computational abilities, memory storage and physical restrictions. Advancement in the field of intrusion and evaesdroping has increased challenges for a secure communication between nodes. So, establishments of pair wise keys in a wireless network becomes a vital issue. Hence, securely distributing keys among sensor nodes is a fundamental challenge for providing seamless transmission and security services. Having little resources in our hand, it is always a tough task to design and implement protocols. But this paper proposes a new robust key pre-distribution scheme which resolves this issue without compromising security. This paper presents a new mechanism to achieve pair wise keys between two sensor nodes by using the algebraic, exponential, logarithm functions and prime numbers. The resilience method under this scheme is based on discontinuous functions which is hard to be spoofed. I
