An error in the mixed adversary protocol by Fitzi, Hirt and Maurer
Abstract: We point out an error in the multiparty computation protocol for mixed
adversaries and zero error from the Crypto 98 paper by Fitzi, Hirt and
Maurer. We show that the protocol only works under a stronger
requirement on the adversary than the one claimed. Hence the bound on
the adversary's corruption capability given there is not tight.
Subsequent work has shown, however, a new bound which is indeed tight.
Category / Keywords: multiparty computation.
