In the epoch of advanced electronic and communication systems, it is being observed most of the times that the information is being assaulted with worms and viruses. To shield the data, a secure and advanced cryptosystem is required to devoid any type of dilemma. There are several tools and techniques that are being used, to meet the challenging needs for a highly secure transmission and reception system. In the spirit of algebraic abstraction, this paper advocates the definition and use of higher levels of abstraction in cryptography (and beyond). If contrasted with the standard bottom-up approach to defining models of computation, algorithms, complexity, efficiency, and then security of cryptographic schemes, our approach is top-down and axiomatic, where lower abstraction levels inherit the definitions and theorems (e.g. a composition theorem) from the higher level, but the definition or concretization of low levels is not required for proving theorems at the higher levels. The goal is to strive for simpler definitions, higher generality of results, simpler proofs, improved elegance, possibly better didactic suitability, and to derive new insights from the abstract viewpoint. Previously security was mainly concerned with the exchange of messages that took place in communication. After that some techniques came into existence that provided more reliable and superior results. But the prerequisite for a more secret system is increase in amount day by day. As the communication system is being more complex, according to the demand more advanced and protected cryptograms are important. In the following paper diverse cryptographic techniques have been analysed that serve the purpose of security from 1900 B.C up to the present day visual.
