We describe the hardware implementation of a novel algorithm for computing the discrete logarithm modulo 2^k. The circuit has a total latency of less than k table-lookup-determined shift-and-add modulo 2^k operations. We introduce a one-to-one mapping between k-bit binary integers and k-bit encodings of a factorization of the integers employing the discrete logarithm. We compare the physical layout result for the circuit when k=8, 16, 32, and 64.
