Generate type A1 pairing parameters and store them in ''p''.
The group order will be ''n''. The order of the base field is a few bits longer.
To be secure, generic discrete log algorithms must
be infeasible in groups of order ''n'',
and finite field discrete log algorithms
must be infeasible in finite fields of order roughly ''n''^2.
Furthermore, ''n'' should be hard to factorize.
Typical values: ''n'' is a product of two primes, each at least 512 bits long.
