The quick progress of this technology becomes vital in upcoming years. Cryptography is where security engineering meets mathematics. It gives us the tools that most modern security protocols rely on. It is perhaps the most important enabling technology for securing distributed systems, yet it is surprisingly difficult to do correctly. Any form of data on a network is private to an individual, and attackers can access it while sharing it with the intended receiver. The demand for availability, confidentiality, Integrity and non-repudiation required for handling is increased. This paper discussed brief about cryptographic methodology and a new model for enhancing cryptographic goals that can be used to secure applications.
