Finite Field Arithmetic

Definition

Finite field arithmetic is a branch of mathematics dealing with calculations within a finite set of numbers. This arithmetic operates on a limited number of elements, where results of addition, subtraction, multiplication, and division always remain within that set. It is a foundational component of modern cryptography, essential for securing digital transactions and communications. In blockchain technology, finite field arithmetic is critical for implementing elliptic curve cryptography, which underpins the security of digital signatures and addresses, ensuring the integrity and authenticity of transactions.
