*Yawn*. It's a combination of a discrete-log-over-GF(2^k) public key
algorithm and an LFSR-based stream cipher. Because they use the same
generator polynomials, they claim i's somehow "integrated" and new,
but the relationship actually ends up making it weaker. The home-brew
stream cipher has been tweaked (adding stuttering in various ways)
to fix the more blatant problems that have been found, but there's
nothing really new there.
It's a cute idea which might be fun to play with, but it's definitely
not worth paying for.
