Abstract

In this paper, we develop and analyze a computationally secure self-healing key distribution scheme with revocation capability, adopting the idea of access polynomial and a one-way hash chain. The main emphasis of our proposed scheme is that it achieves a stronger security goal, namely it can resist collusion against any number of users, while having a significant improvement in the communication overhead as compared to the existing schemes. Our design uses constant storage and hence is especially suitable for unreliable environments in which devices have limited resources. The security analysis is in an existing security model.
