Abstract:

We present a (random) polynomial-time algorithm to generate a random Gaussian integer with the uniform distribution among those with norm at most $N$, along with its prime factorization. The method generalizes to finding a random ideal in the ring of integers of a quadratic number field together with its prime ideal factorization. We also discuss the analogous problem for higher degree number fields.
