Modern Cryptographic Schemes: Applications and Comparative Study

Abstract

Cryptography and encryption have been used for secure communication. In the modern world, cryptography is a very important tool for protecting information in computer systems. With the invention of the World Wide Web or Internet, computer systems are highly interconnected and accessible from any part of the world. As more systems get interconnected, more threat actors try to gain access to critical information stored on the network. It is the responsibility of data owners or organizations to keep this data securely and encryption is the main tool used to secure information. In this paper, we will focus on different techniques and the modern application of cryptography. We will study different cryptographic schemes: symmetric, asymmetric (sometimes referred to as public key), and hybrid systems. The paper will present a comparative study for these schemes and their applications in network protocols. Moreover, we will highlight the concept of Quantum Cryptography, which takes advantage of quantum physics at the physical layer.

Keywords: Cryptography, Data security, Decryption, Encryption, Hybrid encryption.
