【Abstract】 Based on ElGamal’s digital signature scheme, a new sequential digital multisignature and a new broadcasting digital multisignature which based on DLP are proposed. The initial stage of the schemes is simple and the signatures of the schemes are random, so the schemes are highly application and security.更多还原
