What I wanted to say is the method "generates primes that are close to
uniformly distributed over the set of primes in the specified interval",
as stated in Maurer's papers. In other words, the distribution of primes
created is similar that that when using the method of picking uniformly at
random candidates in an interval and passing the Miller-Rabin test
(except, of cours, there is no probability of error (picking a
pseudo-prime)), which most crypto libraries do.
