Q. Explain the random key distribution?
The triple key management mechanisms ensure a better and complete security solution using the random key distribution mechanism. In this case, a "node identity is mapped into the indices one way function using its keys, and "indirect validation with the probability of using a randomly generated identity p" which compels an intruder to make 1/p trials before gaining a usable Sybil identity to compromise the network". The polynomial-based Single-space pairwise key distribution technique has shown drastic resistance to Sybil attacks provide extensive proof that integrating a pre key distribution mechanism and cryptographic schemes into the security paradigm of WSN provides a completely secure network against attacks.
