Abstract. Let B be a ring with 1, C the center of B, G an automorphism group of B of order n for some integer n, CG the set of elements in C fixed under G, ∆ = ∆(B,G,f) a crossed product over B where f is a factor set from G×G to U(CG). It is shown that ∆ is an H-separable extension of B and V∆(B) is a commutative subring of ∆ if and only if C is a Galois algebra over CG with Galois group G|C G
