Today Cloud Computing has became common and most confidential data is changing into centralized into clouds hence for maintaining privacy and security of shared data primarily searchable cryptography is wide used. Sharing of knowledge is a crucial property of cloud computing. we are able to store information on varied information storage servers like e- mail servers and files servers in encrypted form to minimize security and privacy threats however this implies that if we want to get increased amount of security we have to limit the functionality. For instance, if a client desires to retrieve solely documents containing few words, it absolutely was not noted however information storage server perform the search and answer the question while not loss of knowledge and data. As per the property of low maintenance cost, cloud computing delivers an economically suitable and efficient way for sharing various information among cloud users. In this paper, we show how to securely, efficiently and flexibly we share data with others in cloud storage. Unfortunately, sharing data in a multi-user manner while preserving data and data privacy from an untrusted cloud is still a large limitation, due to the change of the membership. In this paper we are introducing an aggregate key for communication in different groups of cloud.
