Cloud computing has been a paradigm shift in the information technology domain. It offers potential benefits to users in terms of instant availability, scalability and resource sharing, while potentially posing security issues. Data is key point in cloud computing for both parties i.e. cloud service provider and application users. So to provide extra security level to data is the main duty of CSP. In this paper, the authors have proposed a technique where data is prime issue and concept of signcryption is here proposed for data security over a cloud.
