Cryptographic Algorithms to Secure Networks - A Technical Survey on Research Perspectives

Cryptology - the art of secret writing is a branch of science with the fundamental objective as “To enable people to communicate securely over a public insecure channel”. Cryptology guarantees secure communication. This paper is to make a survey paper on the evolution of cryptographic systems and the cryptanalysis that lead to the failure of each system over time from the classical cryptosystems till modern cryptosystem. The paper also lights on the new research scopes for budding scholars. The survey takes into account the discovery, the acceptance of the system by the society, the drawbacks thus lead to the discovery of the next cryptosystem. This paper outlines a good idea on the earlier cryptosystems and also gives a spark for new research fields that are yet to be touched and discovered.
