A Compressive Sensing Scheme Based on Zadoff-Chu Measurement Matrix

This paper proposes a compressive sensing framework based on encrypted discrete cosine transform (DCT) sparse and encrypted measurement matrix using partial chaotic Zadoff-Chu matrix transform (ZCMT) for image data. In our proposed scheme, a ZCMT is encrypted by a chaotic sequence, in which the initial value is generated by hashing the transformed image data. In the receiver side, the conventional OMP algorithm is employed to recover the original image data. The PSNR and security performances are evaluated by computer simulation. The simulation results are show that the proposed secure CS scheme has better performances that those of the other measurement matrices schemes.
