A Light Weight and Secure Color Image Cryptography using ECC Algorithm
Subscribe/Renew Journal
Elliptic curve cryptography (ECC) is an algorithm based on the algebraic structure of elliptic curves over finite fields. It provides security to information using shorter keys than other known public-key crypto-algorithms without decreasing the security level. This makes ECC a good choice for the implementation in security services. This paper proposed a hybrid cryptographic approach for color images using ECC algorithm and some mathematical computations. It also compared the various existing image cryptographic techniques and the various issues involved. Regardless there are several related works in the literature, to our knowledge this is the first hybrid approach in order to encrypt and decrypt the color images using some mathematical computations.
