Image encryption technique using lagrange interpolation

Abstract EN

A new proposed technique used to encrypt the private image for secure transfer information.

The proposed technique was designed using the Lagrange interpolation polynomial calculation in key generation and in encryption.

A three stage for encryption and coding was proposed to complete the encryption of private image.

RC6, Quadtree and Xor techniques were used in building the proposed technique.

A short time in operation with a good visual encryption view encryption was got from implementing the proposed technique.
