Bull dolphin, I'll honestly say, I don't know.
The description of SmartSig from the Wave web site:
SmartSignature facilitates the use of digital certificates with its point-and-click signing ceremony. The software seamlessly accesses a certificate and validates a user as authorized to sign a particular document. Documents are stamped and expiration dates are checked, giving the certificate holder the ability to sign global contracts electronically. SmartSignature works with Adobe Acrobat 4.0 and Acrobat Reader 4.0 and higher.
I'm not sure the mechanism of this, but I don't think it involves Wave's TAN.
