Two-Round Multi-Signatures from Okamoto Signatures
Mathematics, 2023 Multi-signatures (MS) are a special type of public-key signature (PKS) in which multiple signers participate cooperatively to generate a signature for a single message. Recently, applications that use an MS scheme to strengthen the security of blockchain
