Abstract/Summary
When the original message is transformed or converted into an unintelligible form, this process is called encipthering. The unintelligible form of the original message is known as the cryptogram. The process of deciphering involves reconverting the cryptogram into its unintelligible form. This thesis presents a program in Turbo Pascal version 5.5 in enciphering and deciphering a cryptogram. The program contains three different methods that one could use in enciphering and deciphering a cryptogram. These methods are as follows: (a.) Transposition (Route Cipher) (b.) Monoalphabetic Substitution and (c.) Polyalphabetic Substitution. Two of the formulas stated in the definitions in this thesis, are results given by Frederick Gass in his article Solving a Jules Verne Cryptogram . The researchers provided some statistical formulas and definitions, since the reference mentioned above does not have enough mathematical definitions.
