An Enhanced Image Encryption Scheme Based on ECC and PWLCM

Abstract

Elliptic curve cryptography (ECC) is an effective approach to protect privacy and security of information. Digital Image encryption is an important issue widely used to protect the data and to ensure the security. Several encryption and decryption cryptosystems are available to keep image secure from unauthorized user. Elliptic Curve Cryptography (ECC) has proven to be the best solution for public key encryption. It provides a good level of security with smaller key size. In this paper we attempt to develop an enhanced Image Encryption Scheme based on ECC and PWLCM (Piecewise Linear Chaotic Map). Here, we generate a key image to enhance data security using ECC and PWLCM. From the experiment results and security analysis, we prove that our scheme cannot only achieve good encryption, but also resist the exhaustive, statistical and differential attacks.

Security Analysis of Medical Images using ECC over RSA

“…There are many security issues related to image processing and transmission [12]. Therefore, the other modern encryption techniques like Chaotic map based [1,21,7], ECC based [7,14], Secure force algorithm [11], SIT [10] are evolved and became very popular in recent years for image encryption.…”
