Information security is the most burning topic in the field of computer science and engineering. Encoding is a very easy process but decoding is not so easy unless we know the apt key. Key management is very important in cryptology. Generating dynamic keys is most essential now a days and also the cipher text.

In mathematics the Z transforms converts discrete data sequence, which is real or complex in to complex domain. It is useful in many areas such as digital Signal processing, control theory, economics etc.

Automata theory is the study of abstract computing devices or machines. In computer science we find many examples of finite state system and the theory of finite state systems, as a useful design tool for these systems.

In the present paper an innovative technique for encrypting and hiding the data is proposed based on finite state machines and Z transformation. The efficacy of the proposed method is analysed, and the analysis shows an improved cryptographic protection in digital signals.

Abstract


Information security is the most burning topic in the field of computer science and engineering. Encoding is a very easy process but decoding is not so easy unless we know the apt key. Key management is very important in cryptology. Generating dynamic keys is most essential now a days and also the cipher text.

In mathematics the Z transforms converts discrete data sequence, which is real or complex in to complex domain. It is useful in many areas such as digital Signal processing, control theory, economics etc.

Automata theory is the study of abstract computing devices or machines. In computer science we find many examples of finite state system and the theory of finite state systems, as a useful design tool for these systems.

In the present paper an innovative technique for encrypting and hiding the data is proposed based on finite state machines and Z transformation. The efficacy of the proposed method is analysed, and the analysis shows an improved cryptographic protection in digital signals.
