MID-Crypt: A Cryptographic Algorithm for Advanced Medical Images Protection

Privacy-preserving of medical information (such as records and images) is an essential right for patients to ensure security against undesired access parties. This typically protected by law through firm regulations set healthcare authorities. However, sensitive-private data usually requires the application further privacy mechanisms such encipherment (encryption) techniques. ’Medical images’ one example highly demanding standards. due quality nature carried among these images, which are with few features tonal variety. Hence, several state-of-the-art encryption images have been proposed developed; however, only a were efficient promising. paper presents hybrid crypto-algorithm, MID-Crypt, secure image communicated between laboratories doctors’ accounts. MID-Crypt designed efficiently hide provide high-security Specifically, uses mix Elliptic-curve Diffie–Hellman (ECDH) masking Advanced Encryption Standard (AES) updatable keys encryption. Besides, key management module used organize public private keys, patient’s digital signature provides authenticity, integrity guaranteed using Merkle tree. Also, we evaluated our algorithm in terms performance indicators including, peak signal-to-noise ratio (PSNR) analysis, correlation entropy histogram timing analysis. Consequently, empirical results revealed superiority scoring best values PSNR, correlation, entropy, overhead. Finally, compared measures other studies, comparison distinguishable common attacks side-channel (SCA), differential attacks, man-in-the-middle (MITM), algebraic attacks.
