Emerging new computing technology cloud offers storage services. Data sharing with others in secure and efficient manner is important function in cloud storage. For this the new expandable public-key cryptosystems which derives fixed-size cipher texts. Using expandable public-key cryptosystems transform the multiple keys of the classes as single secret key. The generated single secret key sent to others or be stored in a smart card with very limited secure storage. If a user needs to classify their cipher texts into more than n classes, user can register for additional key pairs.
