Digital identity-based multisignature scheme implementation

Digital signature, as an official signature, have many applications in information security, including authentication, data integrity, and non-repudiation. When a private or public document must be signed by a group of people, we call it multisignature scheme if all and every single member of the group signs the document. An identity-based digital multisignature is a multi signer digital signature so that the multiple private keys are generated by a trusted third part from signer’s identities. In this paper, an efficient Java implementation to a recent identity-based multisignature scheme based on RSA is proposed. Keywords-RSA; digital signature; multi-signature scheme; Java.
