Medical Image Encryption Scheme Based on Arnold Transformation and ID-AK Protocol

Providing security on transmitted medical image over public channels has become an essential part of computeraided diagnosis systems. In this paper, we propose an efficient image encryption scheme for medical applications based on Arnold transformation and pairing-free identitybased authenticated key agreement protocol. This allows user to send and receive medical images over public channel safely, while maintaining patient privacy. We then provide the numerical analysis results to prove the robustness of our scheme. These results are carried out via both theoretic analysis and experimental simulations based on MATLAB . The analysis demonstrates that our scheme meets the effectiveness and security requirements of image encryption.
