Abstract
The researcher introduced an enhanced classical Arabic-based encryption technique that is essentially designed for Arab nations. The new algorithm uses the shared key technique where the Keyword system Modulus is employed to add randomness and confusion to the table of alphabets being used. The results proved that the technique is resistant to brute force and cryptanalysis attacks. The time needed to break the algorithm is huge and the possibilities of decrypting the cipher text using the language frequency and language characteristics are hard and unfeasible. The technique assumes the existence of a secure channel for the keyword exchange.
