February 2017

Now a day mostly people are doing their daily routine digitally, because current era is based on information and communication technology. But security is one of the most important and challenging issues in this technological world. As per the literature analysis there is a demand for a encryption which should be strong and efficient. Cryptography is a private secure communication in the public world. Cryptography is a technique of protecting secure information from hacking and cracking by unauthorized individuals and converting it into unintelligible form. It provides authentication, identification to user data, confidentiality and also provides security and privacy to the data stored. It is an emerging technology in the area of network security. There is a broad range of cryptographic algorithms that are used for securing networks and presently continuous researches on the new cryptographic algorithms are going on for evolving more advanced techniques for secures communication. The main objective of this paper is to study the basic terms used in cryptography, its purpose and to compare the encryption techniques used in cryptography.
