Exponentiation

Definition

Exponentiation is a mathematical procedure where a base number is repeatedly multiplied by itself according to a power, known as the exponent. In the realm of cryptography, modular exponentiation serves as a foundational component for public-key schemes like RSA and Diffie-Hellman. This computationally demanding operation underpins numerous secure digital signing and key agreement protocols. It is central to modern asymmetric encryption.
