Getting Started

In the last decade, technology has rapidly evolved. Statistics show that 64.2 zettabytes of data were generated in 2020 (1 zettabyte is equivalent to 1021 bytes or 1012 gigabytes), and it is predicted that by 2025, the digital data generated will reach 181 zettabytes [1, 2]. Electronic communication has become an essential part of our lives, and due to its rapid evolution, all manner of security issues has arisen. Because digital messages, in all of their forms, are sent daily over public networks across the world, the need for secure channels and security mechanisms has also increased. Digital devices and communications should have digital signatures that make them easy to authenticate. Modern cryptography provides solutions for all these requirements.
