In any kind of communication, security is the most important thing in today’s world. Bulk of data security and data hiding algorithms have been developed in the last decade, which worked as motivation for the research. The scenario of present day of information security system includes confidentiality, authenticity, integrity, non-repudiation [1]-[3].
This present work focus is enlightening the technique to secure data or message with authenticity and integrity [4]-[6]. With the growth of internet and network, the need for secure data transmission become more and more essential and important, as security is a major concern in the internet world. Data likely to be kept hide from all people except from the authorized user cannot be sent in plain text [7]-[8]. So the plain text should be codified by the process of encryption.
Every single type of data has its own features; therefore several kinds of techniques should be used to protect confidential data from unauthorized access. Here we are introducing a new algorithm which is based on simple graph operation. In this algorithm encryption is done on binary file so it can be applicable for any type of data such a text as well as multimedia data. Here the idea of cryptography is using key, conversion of plain text into cipher text called encryption and the reverse, means cipher text to plain text called decryption [9]-[12].

In todays world for any kind of communication, security is the most important thing. There are huge number of data security and data hiding algorithms have been developed in the last decade, which worked as motivation for the research.
This present work focus in technique to secure data or message with authenticity. With the growth of worldwide communicational network and internet, the necessity for secure data transfer become more and more essential and important, as security of data is a major concern in todays internet world. Data must be kept in hidden form from the unauthorised user or any kind of hacker attack, so we need to make our data safe and secure by implementing more secure encryption technique.
Every kind of data has its own characteristics, so we need different kind of encryption techniques to make secure our data. In this algorithm we are introducing a new kind of techniques using simple arithmetics operations.
