摘要：Cloud computing technology is widely used so that the data can be outsourced on cloud can accessedeasily. Different users can share that data through different virtual machines which present on single physical machine.But the thing is user don’t have control over the outsourced data. The main purpose is to share data securely amongusers. The cloud service provider and users Authentication is necessary to make sure no loss or leak of users data incloud. Privacy preserving in cloud is important. Cryptography helps the data owner to share the data to the requesteduser in safe way. For that the data owner encrypts the data and uploads on server. The encryption and decryption keysmay be different or same for different set of data. For decrypting the required data only the set of decryption keys areshared. Here a public key cryptosystems which generates a ciphertext which is of constant size. The difference is onecan collect a set of secret keys and make them as small size as a single key with holding the same ability of all the keysthat are formed in a group as aggregate key.
