Comments on: EIBAS - an efficient identity broadcast authentication scheme in wireless sensor networks

Yalin Chen and Jue-Sam Chou

Abstract: Recently, Shm et al. Proposed an efficient identity-based broadcast authentication scheme based on Tso et al.ís IBS scheme with message recovery to achieve security requirements in wireless sensor networks. They claim that their scheme can achieve security requirements and mitigated DOS attack by limiting the times of signature verification failures in wireless sensor networks (WSN). However, we found that the scheme cannot attain the security level as they claimed. We will demonstrate it in this article.
