In compressive sensing, a signal can be reconstructed from a small set of non-adaptive, linear measurements if the signal can be represented as a sparse objective in some orthonormal basis. The authors propose a compressive sensing based secure data transmission scheme in this paper. Only simple linear operations are required in the encryption end and complex computations are transferred to the resource-rich decryption end. The encryption phase and decryption phase are described in detail. They also provide the perfect secrecy proof and the experiment results of signal and image encryption to verify the effectiveness of the proposed scheme.
