Cloud computing is a newfound service which has rapid growth in IT industry recent years. With the development of social network, group data sharing system been developed to store and process large amounts data. Due cloud provided by third party, server semi-trusted. In this paper, we propose secure identity-based dynamic scheme for computing, based on transplanted signature algorithm perform identity authorization authentication. order make members share efficiently, utilize multi-owner searchable encryption mechanism realize sharing. The security analysis shows that our proposed can resist many possible attacks. addition, performance be implemented with low computational cost.
