Multilanguage block ciphering using two dimensional substitution array

In order to send information securely and to protect the same from the understanding of other, people around the world are using the various cryptography method of writing information. But for getting the Cipher by adopting the Multilanguage Encryption Technique (MULET) [1], one has to apply two types of Replacement called `Character´ and `Numerical´. The resultant Cipher is a stream cipher. The Multilanguage Two Dimensional Array Substitution method (MTDAS), which is being introduced in this article replaces two different arrays in to single two dimensional array, it supports more number of cipher alphabets for the same Mapping array value and it ensures the versatility [6] of the classical cryptography. The resultant Cipher´s length will be a block cipher and at the same time it conforms to Multi-language. Hence, others will find it very difficult to understand the information and their efforts to decipher the information will prove futile. By using this new method it is possible to encrypt information in all the languages in the world that are in the Unicode [10].
