英文摘要	Undeniable signature is a variant of digital signature that can only be verified only with the signer's consent and it is useful to protect signer's benefit. In this paper we proposes a new signature scheme named 'multi-undeniable signatures' based on general undeniable signature that can protect jointed copyright of a group users. We describe its definition and security model, then construct a practical scheme based on Elgamal encryption. Our work extends application areas of undeniable signatures. ? 2011 IEEE.; EI; 0
