Abstract: Multi-party signing and encapsulation of messages (transactions/documents) that support multiple asynchronous signers and multiple recipients. There must be some mechanisms and protocols to create and distribute protected transactions/documents between participants with flexible verification of such transactions/documents.The main objectives of our new model of a Multi-party transaction protocol to support for secure creation, distribution, verification and different legal assurance levels of signatures of multi-party (sequential and parallel) processing of transactions between multiple signers and verifiers. Therefore, it may be used for protection of various electronic transactions or documents exchanged between multiple participants.
