Really short digital signatures



Hi,

Is there any reasonably common and safe method of generating digital signatures which are really short? By "short" I mean it would be ideal if it could be around 16 bytes and by "common" that it is already present in some open source library.

I know DSA has smaller signatures than RSA, but from what I've found it looks like it still needs at least 512-bit or 1024-bit signatures to be reasonably safe. Is using smaller DSA parameters the best I could do?
