Ah good.

Well as you know, RSA keys are described as follows:

Private key description: (n, d) is the (modulus, private key exponent)
Public key description:  (n, e) is the (modulus, public key exponent)

In DSA as per:

Private key description: (x, g, p, q) is the (private key, generator,
modulus, sub-group order)
Public key description: (y, g, p, q) is the (public key, generator,
modulus, sub-group order)

So I think the naming is doable.  To start with what do you think of the
terms:

g=generator
p=modulus
q=subGroupOrder
