Coding theory is about ways to properly relay information. It is a comprehensive theory that is the result of numerous mathematical developments. Research is conducted with a focus on algebra, including coding theory as a mathematical theory and related group theory, and ring theory. Research is also conducted into analytic number theory as it relates to ciphers.
