In group theory, the Pohlig–Hellman algorithm, sometimes credited as the Silver–Pohlig–Hellman algorithm, is a special-purpose algorithm for computing discrete logarithms in a finite abelian group whose order is a smooth integer. The algorithm was introduced by Roland Silver, but first published by Stephen Pohlig and Martin Hellman (independent of Silver). WebIn the medium-term, transitioning to Elliptic Curve Diffie-Hellman (DH ECC) key ex-change with appropriate parameters avoids all known feasible crypt-analytic attacks. Current elliptic curve discrete-log algorithms for strong curves do not gain as much of an advantage from pre-computation [6]. On the other hand, it is important to pay
