It certianly isn't alone in this. Most public signature schemes, with the
exception of RSA have some form of subliminal channel. Further, recent
papers suggest that DSA was strengthened against subliminal channels -
they're still there, but they could have been worse.
DSA authenticated DH is a good patent free substitute for RSA.
