WebIntroduction to finite fields . To understand AES and some other modern cryptosystems, it is necessary to understand a bit about finite fields. A field is an algebraic object. The … WebCorollary 4.1. If we consider Ha,b over finite fields of characteristic 3, the ∆ value is always a quadratic non residue. Therefore if A is the set defined in section 2., algorithm 4 is an injective encoding from A into points Ha,b for these finite fields. Remark 4.2. We know that the set of points on Ha,b is not a group.
