New ElGamal Type Broadcasting Digital Multisignature Scheme
Yixian Yang · Jisuanji gongcheng · 2007
All of the existing ElGamal type broadcasting digital multisignature schemes have a problem: Data should be exchanged many times among signers to get the same signature parameter which would lead to high communication and insecurity. A new sequential multisignature scheme based on discrete logarithm problem without the mentioned problem is proposed. The new scheme is applicable and secure.
