Design of Hybrid Cryptography System based on Vigenère Cipher and Polybius Cipher

The Cryptography is gotten from a Greek word which implies the craft of ensuring data by changing it into a muddled organization and unreadable format. It is a mix of arithmetic and software engineering. The dynamite growth of the Internet has made an expanded familiarity with intrigue uncertainty issues. Even though security is the measure worries over the internet, numerous applications have been created and structured without considering fundamental destinations of data security that is confidentiality, authentication, and protection. As our day by day exercises become increasingly more dependent upon data networks, the significance of an understanding of such security issues and trouble will also increase. To forestall some undesirable clients or individuals to gain admittance to the data, cryptography is required. .This paper introduces a new hybrid security cipher by combining the two most important Ciphers such as Polybius Cipher and Vigenère Cipher. This hybrid encryption cipher provides greater security as compared to classic ciphers.

I. Introduction

In the present direction of the world, the innovations have progressed so much that the vast majority of the people incline toward utilizing the internet as the essential intends to consign data starting with one end then onto the next over the world. There are numerous potential approaches to communicate data utilizing the internet: through messages, talks, and so on. The data change is made very snap, quick and exact utilizing the internet. In any case, one of the primary tests with sending data over the internet is the "security risk" it presents, for example, the individual or privy data can be packed away or hacked from various perspectives. In this way, it turns out to be essential to mull over data security, as it is one of the most vital variables that need consideration during the process of data transfer [1].
