Medical Images are Safe – an Enhanced Chaotic Scrambling Approach

In this study, the pseudo random number generators (PRNGs), namely, the linear congruential generator (LCG) and XOR shift generator (XSG ) are improved and combined with improved logistic 2D coupled chaotic map to provide enhanced chaos based encryption. The proposed scheme encrypts the Digital Imaging and Communication in Medicine (DICOM) images to protect the patient confidentiality during the storage and transfer in radiological i nformation system (RIS). The cipher image was measured with various security analyses and tested with different test suites to prove its randomness.
