Apparently that's a typo.  SymEnc() and SymDec() should be
*authenticated* symmetric encryption and decryption primitives but
apparently their definitions were lost in an edit and one instance was
changed to SymMacEnc() (see line 2).  For simplicity, replace instances
of SymEnc() and SymDec() in Algorithm 4 with SymMacEnc() and SymMacDec().

I don't believe that the talks were recorded (though if someone
surreptitiously made a recording of my talk, I'd love a copy).

Cheers,
