At present market, with the help of science, the information technology has developed rapidly as well as the information security as an important part of information technology is also strongly affecting people’s work and life. When the development of science and technology brings convenience to characters, it also exposes many security issues. In recent years, information security incidents such as information leakage, SQL injection vulnerabilities, network penetration, and hacking attacks have triggered irreparable losses to enterprises, society, and individuals. In our paper, a symmetric key encryption with fuzzy based session key has been proposed for satisfying the key issues like security; increase the strength of symmetric key. Here the session key is generated using fuzzy logic. Now the encryption is done by using this session key and symmetric key. Here a new authentication scheme is developed to generate cipher text. Different types of experiments to test the robustness of keys and encryption technique and comparative study with existing standard techniques have been done with satisfactory results. This paper has taken steps to develop an attack capability for use within a cyber challenge environment. The principles discussed within this paper aim to be applicable to all challenges against mathematical cryptanalysis and cryptographic protocol in general and also it is used to cover threat modeling, construction of cyber security test beds and take footsteps against offensive cyber operations.
