Abstract
The present invention disclosed a method operable on a multiparty signing system for performing a multiparty signing act on a digital content. The multiparty signing system disclosed in the present invention comprises at least two multiparty signing servers configured with methods to perform the multiparty signing act of a digital content to sign. The multiparty signing system can be configured to perform the multiparty signing act by a private signing key split to at least two key shares, wherein each key share is held by each of the at least two multiparty signing servers. The multiparty signing system is also configured to communicate with at least one computerized node employed to conduct an approval process for approving the multiparty signing act. The approval process can be configured to conduct the approval process by employing a secure multiparty computation, wherein the approval process is configured to utilize secret shares held by the at least one computerized node. In such cases, the multiparty signing act is approved in case the approval process ended successfully.
