摘要：This paper demonstrates the sharing of data in cloud in a safety and unique way. The data sharing incloud is a requisite functionality and providing security to this data during data sharing. It is an important and essentialfunctionality, because the data might be susceptible to privacy and security issues which will minimizes the efficiency.The present work guarantees solutions to above concerns such that efficiency, privacy and security during sharing ofdata. A new public key encryption called key aggregation technique is discussed in this work. Key aggregationtechnique produces constant size ciphertexts, so that decryption of any set of ciphertexts is possible. Here, theindividuals can aggregate any number of secret keys into a single one by holding the power of all keys. One who holdsthe aggregated key can share the key for accessing of files by maintaining the confidentiality of other files which hewouldn’t like to share. This aggregated key can be sent to others for decryption of ciphertext sets.
