Abstract
Classical encryption methods depend on two basic encryption method, namely MONO ALPHABET and POLY ALPHABET.
In this research, we developed a hybrid encryption algorithm to overcome the weaknesses in both methods and employed the basic methods of themselves. The output ciphertext is characterized with the high security when it does not give the expected results using the basics to break the code, namely, (adoptig the frequencies of the language used i.e. Frequency Analysis, besides Coincidence and Kasiski test).
The problem of distributing the secret key has been also overcome by adopting a new technique to hide the key inside the encrypted text in a nearly proposed way. Experimental result has been demonstrated that it is difficult to determine the used encryption method ,in this algorithm we used MATLAB.
