Abstract
Self-healing group key distribution is a recent attended research topic in the literature. Common approaches for self-healing schemes use redundancy into broadcast message which would allow user nodes to recover previous session keys, lost due to communication errors. The redundant information lead to communication overhead, but this paper aims to address this concept, by one-way functions, without redundancy. We apply our idea in identity-based cryptography and pairing operations. Our proposal can enable a node in lossy network to recover its lost session keys efficiently along with providing acceptable forward/backward secrecy and collusion resistance.
