Modified Autonomous Key Management Scheme with Reduced Communication/Computation Costs in MANET

The growing applications of Mobile Ad hoc Network (MANET) has made the security issue increasingly more important. B. Zhu et al. proposes a key management scheme using Shamir´s secret sharing scheme to construct an Autonomous Key Management (AKM)hierarchy structure. However, Shamir´s secret sharing in AKM to control key hierarchy needs larger message transmission costs. In this paper, we modify the secret sharing scheme and apply it to AKM for reducing communication and computation cost.
