Field Arithmetic

Definition ∞ Field Arithmetic refers to the mathematical operations performed within a finite field, which is a set of numbers where addition, subtraction, multiplication, and division are well-defined and always result in an element within that same set. These operations are foundational to many cryptographic algorithms, ensuring computational predictability and security. Finite fields are crucial for constructing robust cryptographic primitives, enabling the integrity and confidentiality of digital information. The closure property of these fields is particularly important for cryptographic constructions.
