An Efficient and Secure Transmission Model Based on Compressive Sensing

摘要

Compressive sensing (CS) can compress and reconstruct sparse or compressible signals with fewer samples than those of Nyquist-Shannon theorem requires. In order to meet the requirements of storage, energy-efficiency and security of wireless sensor networks (WSNs) simultaneously, we propose an efficient and secure transmission model based on compressive sensing and hash-chain theory. Compared with the traditional compressive sensing, only the initial key and the hash function are used in the sensor node to decrease the storage space. And the characteristics of hash-chain assure the security of data transmission. The numerical experiments are performed to show the feasibility and the effectiveness of the proposed model.
