Per-user keys-DSA Algorithm

Per-user keys

Given a set of parameters, the second phase computes private and public keys for a single user:

Choose x by some random method, where 0 < x < q.
Calculate y = gx mod p.
Public key is (p, q, g, y). Private key is x.

There exist efficient algorithms for computing the modular exponentiations h(p�1)/q mod p and gx mod p, such as exponentiation by squaring.
