Review and Open issues of Cryptographic Algorithms in Cyber Security

Security has been a primary focus in all the areas of communications and also has become a big problem for all kind of companies dealing with heterogeneous data. To overcome the security issues, we have cybersecurity specialists and experts around the world but the finding and hiring these people are difficult due to expenses accordance with projects. The researchers have focused on some of the issues of cryptographic algorithms to review it and provide solutions in terms of research and development. Furthermore, we discuss cryptographic algorithms which may help to reduce security issues around the world, but some issues are rigorous, so will discuss here and review it according to standard encryption and decryption methods in cryptography. Some of the encryption and decryption algorithms consider and explain some excellent examples for the researchers to find it for a better comparison in the field of cybersecurity. Our effort may help researchers to enhance security capabilities in terms of cryptographic algorithms in general. We provide a summary of different algorithms in this paper and elaborate open issues together with discussions that may help us to reduce problems of security issues.
