Abstract: In this paper, a novel multisignature scheme based on chaotic maps is proposed. The purpose of multisignatures is to manage the complexities of a document signed by numerous signatories. The chaotic system is an encryption method proposed in recent years that has received widespread attention in the field of cryptography. This paper first examines the methods of multisignatures and chaotic maps, and then proposes a multisignature scheme that was designed using chaotic maps. During the processing of a multisignature scheme, to authenticate the precision of the received document, the signatory must first obtain the signed document, and then utilize the characteristics of chaotic maps to recover the original document. If the recovered document is meaningful, this indicates that no errors exist in the signature, thus the signatures are valid and the document can be signed. If the recovered document is not sufficiently clear, signing is denied. At present, because no relevant literature exists that has proposed utilizing chaotic maps to establish a multisignature system; this paper aims to develop a novel research method.
