| Abstract(in English) | A new multi-signature scheme is proposed. The length of a signature computed following the scheme is independent of the number of the signers and constant. Forgery of a signature is computationally equivalent to computation of the secret pieces of information of its signers. The scheme can be constructed with Okamoto's signature scheme or Schnorr's signature scheme. When m signers sign a document, each of them should be assigned an index in{1, 2, ..., m}, which, for example, can be determined by the lexicographical order of their ID's. This index is independent of the order of signing. |
