Routing Authentication Chain Mechanism to Resist AODV Black Hole Attacks
Kunyu Liu, Liang Zhou · 2020
The black hole attack is a main kind of attack against the ad hoc on demand distance vector (AODV) protocol in ad hoc networks. A much greater threat is a joint attack of multiple black holes. To prevent black hole attacks, this paper proposes an authentication chain mechanism based on the secure recursive function, by which the successive nodes of a route are unified only on the deterministic state transition relation of the recursive function to implement a unique association for security, such that the whole route forms an authentication chain. With the mechanism of this paper, even if a pseudorandom linear sequence is adopted as a kind of simple recursive function, as long as its linear complexity is greater than the number of nodes in the authenticating chain, the attacker cannot obtain continuous state values of more than two times the linear complexity of the sequence, Thus the secure authentication of the route can be guaranteed. Therefore, the mechanism and method presented in this paper represent a novel and effective approach to defend against black hole attacks.
