Cloud computing is a general term for anything that involves delivering hosted services over the Internet. It is being forecasted that more and more users will rent computing as a service, moving the processing power and storage to centralized infrastructures rather than located in client hardware. This is already enabling start-ups and other companies to start web services without having to invest upfront in dedicated infrastructure. However, a major barrier for cloud adoption is real and perceived lack of security. Digital certificates are an essential part of the foundation that enables secure digital communications, providing secure access to data, applications and cloud infrastructures. Digital certificates are an established, standards-based method to enhance trust over vulnerable networks. They are the digital equivalent of a driver’s license or any other form of identity issued by a trusted third party in the physical world. In this paper we have discussed the cloud security by certificate authority technique.
