The cloud computing is Internet based computer, shared software information and resource to world. These cloud environment resources are shared to all servers, and separate users. The cloud computing supports distributed services multi-domain Infrastructure, and multi-users. This paper proposed user authentication to secure data of encryption algorithm with digital signature in cloud computing. This infrastructure guaranteed to secure the information in cloud server. The technology of distributed data processing in which some scalable information resources and capacities are provided as a service, to multiple external customers through Internet technology.
