Security Analysis of Medical Images using ECC over RSA

The security of medical images is very important to maintain the confidentiality and privacy patient information. Medical practitioners are required adopt policies for access patient’s electronic This paper provides analysis Images based on Elliptic curve cryptography. cryptography (ECC) a complex method involves intense computation which makes it robust intruder attack. In this paper, ECC Image Encryption algorithm performed varieties like MRI, CT scan X-ray. Security presented Histogram, Entropy, NPCR UACI measures compared with traditional RSA. Histogram after encryption using has uniform distribution reflects that information original image hidden properly. Entropy achieved 7.86 – 7.99 99.62 99.64 % respectively close their ideal values. Results reveal more powerful useful authentication key distribution. However, can be used exchange secret rather than encryption.
