WebDec 23, 2024 · Exercise 4.2. For the AES algorithm, some computations are done by Galois Fields (GF). With the following problems, we practice some basic computations. Compute the multiplication and addition table for the prime field G F ( 7). A multiplication table is a square (here: 7 × 7) table which has as its rows and columns all field elements. Web2 Corollary. Let L ⊃ F ⊃ K be fields, with L/K galois. Then: (i) L/F is galois. (ii) F/K is galois iff gF = F for every g ∈ Aut KL; in other words, a subfield of L/K is normal over K …
