WebIf the order of a curve defined over a field F p is equal to p, then that means the curve is anomalous, and there's an attack (called Smart's attack) that we can apply to solve the discrete log easily. So we can apply this to the curve defined over F p. This also implies that every point generated by the curve also has an order of p.
