  • Abstract:
  • Cloud computing technology is widely used so that the data can be outsourced on cloud can accessed easily. Different members can share that data through different virtual machines but present on single physical machine. But the thing is user don’t have physical control over the outsourced data. The need is to share data securely among users. The cloud service provider and users authentication is necessary to make sure no loss or leak of users data. New public–key encryption which is called as Key- aggregate cryptosystem (KAC) is introduced. Key-aggregate cryptosystem produce constant size ciphertexts such that efficient delegation of decryption rights for any set of ciphertext are possible. Any set of secret keys can be aggregated and make them as single key, which encompasses power of all the keys being aggregated. This aggregate key can be sent to the others for decryption of ciphertext set and remaining encrypted files outside the set are remains confidential.
