A Remark on a Signature Scheme where Forgery can be Proved

A new type of signature scheme, a signature scheme where forgery by an unexpectedly powerful attacker is provable, was suggested in [WaPf1_89]: if the signature of an honest participant Alice is forged, she can prove this forgery with arbitrarily high probability. The possibility of proving forgeries does not depend on any unproven assumptions. Th
