Abstract
The process of rekeying is required to preserve forward and backward secrecy which induces computational and communication overhead. In dynamic environments, the members move from one position to another or frequent join/leave in the multicast service increases the key management overhead (rekey). When the members become more dynamic, the rate of rekeying increases and hence the overhead increases. This study proposes an Adaptive Secure Authenticated Key Establishment (ASAKE) Mechanism which reduces the effect of state-full member expectation, out-of-sync problem and overhead per rekeying. Also, any change or dynamism in the multicast service group membership results in rekeying and hence in overheads. ASAKE reduces the frequency of rekeying by using a multicrypt and predictive rekeying mechanism and introduces an novel adaptive architecture which keeps the trade-off between 1-affects-n problem and key translation overhead in balance. The performance analysis of the proposed ASAKEshows reduced effect of mobility on the key management protocol. The performance analysis also show that ASAKE is highly scalable and the rekey overhead saved by ASAKE is significant over other standard key establishment protocols.
