N2  - With the development of technology, studies to ensure privacy and security have gained importance. Fortransmitting information between sender and recipient sides without getting third parts many methods have beendeveloped. In this study, according to irreducible polynomial that is determined between the parties (sender andrecipient), the pixel values of grayscale images which are of size 128x128 that are expressed by finite field elementsover Galois Field (28) (GF(28)). Polynomial coefficients of each finite field element considered as 8-bit binary number,than this number is converted to decimal number. These decimal numbers are replaced with the original grayscalepixel values than encrypted image is sent to the recipient. In this study Matlab is used to getting finite field elements,encryption and decryption process. Thanks to improved method encrypted grayscale images are decrypted as lossless.
