A function is bijective if and only if has an inverse
30-Nov-2015 We say that f is bijective if it is both injective and surjective. Definition 2. Let f : A ? B. A function g : B ? A is the inverse of f if f ...

PRACTICAL BIJECTIVE S-BOX DESIGN
Our construction is based on using non-bijective power functions over the finite field. 1 Introduction. A vectorial Boolean function is a map from n.
Week 2
A function is said to be bijective if it is injective and surjective. Definition 0.5 (Equivalence). We say that two sets A and B are equivalent.

A surjective function is also called an surjection. A bijective function is also called a bijection. Proposition 3.1. Let A and B be finite sets and f : A ? B.
