Abstract

In this letter, we point out that key substitution attacks should be taken into account for multisignature schemes, which implies that the existing security notions for multisignature schemes are not sufficient. As an example, we show that the multisignature scheme proposed by Boldyreva at PKC'03 is susceptible to key substitution attacks.
