abstract = {Security of digital images has become one of the most important issues in network technologies. Different techniques have been evolved over the past few years to provide security for digital images through concealing information, image scrambling and image encryption. The aim of this work is to enhance the network security level by using the cryptographic method based on the Least Square Approximation technique (LSA). This work is one of the first attempts due to the use of the least squares polynomial of fifth degree technique as data interpolation in the image cryptography process. It has been proven in this study that a high level of correlation exists amongst the original and the corresponding decrypted images. The achieved high values of the measured Peak Signal to Noise Ratio (PSNR) for the decrypted images in this study are an indication to the high accuracy of the proposed technique in comparison to other cryptographic techniques. The output of the encrypted technique in this study reveals its reliability and robustness against security attacks.},
