Cryptography and Encryption Techniques- A Survey

Abstract

Today security plays an vital role to protect your information from intruders and hackers. Information security is the most extreme basic issue in guaranteeing safe transmission of data through web. Also network security issues are now becoming important as security is moving towards digital information era. As more and more users connect to the internet it attracts a lot of cyber-attacks. After noticing constant reports of data, theft and hacking, enhancing security of data has become mandatory. The encryption techniques and various algorithms are used to provide the required security to the applications. This paper deals with the overview on network security and various techniques through which network security can be enhanced i.e. Cryptography. Cryptography provides Confidentiality, Integrity, Non-repudiation and Authentication.
