Pohlig Hellman Algorithm – Algorithm Hall of Fame

WebApr 19, 2015 · Both methods are quite slow for large p. Pohlig-Hellman is a significant improvement when p-1 has many factors. I.e. assume that. p-1 = n r. Then what Pohlig and Hellman propose is to solve the equation. y n == (g n) z (mod p). If we take logarithms to the basis g on both sides, this is the same as. n log g (y) == log g (y n) == nz (mod p-1).
