A Perturbed Compressed Sensing based Authentication Mechanism in Multi-hop Wireless Sensor Networks

The design of high efficient security mechanisms in resource constrained multi-hop Wireless Sensor Networks (WSNs) has always been a hot topic. Recently, compressed sensing (CS) has drawn great attentions for it can jointly compress and encrypt data with low energy cost and low computational and storage overhead. However, existing work only focuses on the data confidentiality rather than data authentication, integrity, etc. In order to achieve authentication and integrity without any extra communication overhead, this paper proposes a secure data transmission mechanism based on perturbed CS by introducing perturbations for authentication. We conduct extensive experiments to evaluate the performance of the proposed mechanism; the experimental results demonstrate the proposed secure mechanism can achieve authentication and integrity in multi-hop WSNs.
