Reversible authentication of wireless sensor network based on prediction-error histogram and CRC

Abstract

In this paper, a reversible authentication scheme for wireless sensor network (WSN) is proposed. Firstly, the WSN data stream is divided into some authentication groups, and each authentication group is composed of a generator group and a carrier group. Then the cyclical redundancy check (CRC) code of generator group is produced as the authentication information. In the carrier group, using the prediction-error-based histogram shifting algorithm, the authentication information is reversibly embedded into the fluctuation region of prediction-error histogram (PEH), not the smooth region. Experimental results and analysis demonstrate that compared with previous schemes, the proposed scheme achieves better performances on computation complex, false tampering alarm and attraction to attackers.
