Protection against Mobile Adversaries in Mobile Ad-hoc Networks
Ronghua Shi, Yanhua Yan · 2008
A proactive secret sharing scheme (PSS) is very important to withstand mobile adversary in mobile ad-hoc networks (MANETs). It allows a set of nodes to update all shares by generating a new set of shares for the same secret key from the old shares without reconstructing the secret key and it allows the nodes to recovery the lost shares. After periodical renewal, it makes the mobile adversary which wants to get the secret key of the system to attack another set of nodes in a new period. In this paper, we presented a PSS synchronization structure in an MANET environment and we supply the scheme with the improved share recovery procedure for perfection. Finally we analyze the protocol and outline our future work.
