We directly reduced the Duursma-Lee algorithm applying the theory of divison from the defination of Tate Pairing. Then we introduced a new equavalent defination of Tate pairing of supersingular elliptic curve over finite fields with characteristic three or two, that it has lower final exponent. We proposed two refined algorithms of the modified Duursma-Lee algorithm.
