I'm probably being too literal here, but I don't get where the 'G' appears in the "following equations"?

The calculation of the DAC is given by the following equations where G represents the Exclusive-OR of two vectors. 

 01  = e(D1)
 02  = e(D2 + 01)
 03  = e(D3 + 02)
 On  = e(Dn + 0n-1)

The algorithm also seems to call for DES encryption and a secret key. I think the the duality of the term 'digest' is screwing me here. "64-bit hashing algorithm" seems to turn up better hits.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
