EIBAS: An efficient identity-based broadcast authentication scheme in wireless sensor networks

Author: Kyung-Ah Shim, Young-Ran Lee, Cheol-Min Park

Abstract
In this paper, we propose an efficient identity-based broadcast authentication scheme, EIBAS, to achieve security requirements in wireless sensor networks. To minimize communication and computational costs, we use a pairing-optimal identity-based signature scheme with message recovery, where the original message of the signature is not required to be transmitted together with the signature, as it can be recovered according to the verification/message recovery process. The EIBAS scheme achieves a minimization of communication overhead, allowing the total energy consumption to be reduced by up to 48.5% compared to previous identity-based broadcast authentication schemes.
