Implementation of cryptographic algorithm for secured communication in tamil language using python program Available to Purchase

The field of Cryptography serves as a crucial aid in all the circumstances where a secured and a safer communication has to be constructed. The word ‘Crypto’ means ‘hidden’ and ‘graph’ means ‘to write’. So far, several cryptographic algorithms have been put forth and implemented, thereby establishing more private communications in English language and in Machine language as well. Since, technology provides the facility to communicate in any desired language, these existing algorithms must be developed and practiced in many languages at a broader extent. But considering the complexity of each language, developing a cryptographic algorithm has not been carried out. Tamil happens to be one of the classical languages. We have developed a cryptographic algorithm to ensure secured communication in Tamil language. But still, manual encryption could become difficult for us to handle in all the situations. In order to overcome this kind of complication, we aim at executing this encryption and decryption algorithm with the help of a programming language. This will reduce the human energy and time consumption which will also be far easier and accurate than the manual performance. Thus, in this paper, we have developed a Python program that will encrypt the message given in Tamil language which shall be the extended version of classical Julius Caesar’s method. But because of the larger alphabet structure, the disadvantages occurred while implementing this algorithm in English does not seem to hold for Tamil language. Moreover, we have implemented dual key pattern and uyir mei decomposition technique to strengthen the security. Hence, this would be highly helpful for anyone to communicate with Tamil script itself in a secured manner that too without any hassle.
