The proposed work has been done by using two extra<br />rounds and depending on round statuse ( even or odd) , messages are detected<br />to be used. The key is placed in agreed positions, then the remaining positions<br />are filled with the message, and then certain sums are calculated to represent<br />the encrypted text. Speed, complexity, histogram calculations for images, and<br />NIST calculations for texts were calculated, and the results were compared,<br />where the complexity of the algorithms was as follows ((P)15 × (256)10)2 × (P)11<br />× (256)14 and ((256)15 × (256)10)2 × (256)11 × (256)14 for GF(P) and GF(28)<br />respectively , From that, it has been discovered that the proposed algorithm<br />(Magic Square of order five with multi message length) is better than the rest of<br />the algorithms as it has excellent complexity and a slight difference in the<br />speed.https://ijccce.uotechnology.edu.iq/article_169704_ef5c643b891c64f0d5c84192fd796c30.pdf
