In the proposed scheme, the partial key [d.sub.P] = s + x[H.sub.1] ([ID.sub.P], [omega], [pk.sub.P]) is used instead of [ID.sub.P] to ensure the Patient's anonymity.
Unlike usual proofs in which every user with a unique partial key signcrypts one message, in our proof each node aggregate-signcrypts a number of messages [m.sub.i][for all]i by generating a special key [k.sub.i] for every message.

Indeed, McLachlan points out, the data suggest that two binding sites exist and that both "would have to be occupied for the synergy to occur."
