English Abstract

Users of Internet daily send and receive many images through social media.

These images are vulnerable to hack and tamper by attackers.

Therefore, it is necessary to develop methods to protect these images against attackers.

In this thesis, a non-traditional encryption method for encrypting images is presented that makes images more protected and secured.

The main idea in this work is based on building strong encryption algorithm through implementing the substitution and transposition operations on colors' values of the pixels.

These operations are implemented depending on extracted chains from the secret key used in the algorithm.

Also, the proposed encryption method uses proportionally large random key (minimum 2048 bits size).

This key adds more difficulties in the face of attackers.

The required programs have been written to implement the proposed encryption method.

Set of numerical (such as Signal to Noise Ratio (SNR), the Normalized Mean Absolute Error (NMAE)), statistical analysis (color histogram) and visual tests have been used to evaluate the proposed encryption method.

The comparison results between the proposed method and other well-known encryption methods showed that proposed method can be used effectively to provide good protection for the image
