Generic on-line/off-line threshold signatures

By Chris Crutchfield, David Molnar, David Turner and David Wagner


1 Introduction We present generic on-line/off-line threshold signatures to improve the perfor-mance of threshold signature schemes, and we show how to construct such signatures from existing threshold signature schemes. In a threshold signature scheme,given a group of n players, and a threshold t < n, no subset of the players of sizeat most t can generate a signature. In other words, unlike standard signatureschemes-- in which a single player must protect his or her secret key-- at mos
