Web- Pohlig-Hellman is a generic algorithm that can be used to attack any group-based cryptographic protocol that relies on the discrete logarithm problem. This means that if Pohlig-Hellman were a practical threat to Diffie-Hellman key exchange, it would also be a threat to other cryptographic protocols that use the same problem, such as digital ... WebSTEPHEN C. POHLIG AND MARTIN E. HELLMAN, MEMBER, IEEE Abstract-A cryptographic system is described which is secure if and only if computing logarithms over GF(p) is infeasible.
