Summary:An image encryption scheme based on a four-wing hyperchaotic system combined with compressed sensing and DNA coding is proposed. The scheme uses compressed sensing (CS) to reduce the image according to a certain scale in the encryption process. The measurement matrix is constructed by combining the Kronecker product (KP) and chaotic system. KP is used to extend the low-dimensional seed matrix to the high-dimensional measurement matrix. The dimensional seed matrix is generated by a four-wing chaotic system. At the same time, the chaotic sequence generated by the chaotic system dynamically controls the DNA coding and then performs the XOR operation. Simulation experiments and performance analysis show that the algorithm has good performance and security. •An image encryption based on compressed sensing and DNA is proposed.•Kronecker Product is used to construct the measurement matrix.•Simulation analysis show that the proposed algorithm has good performance and security.
