Abstract

Cloud storage is a model of data storage in which the digital data is stored in logical pools, the physical storage spans multiple servers and physical environment is managed by the hosting company. One of the major functions of cloud storage is sharing of data. In this paper, we use a new public key cryptosystem which use a constant size ciphertext. This can provide an efficient decryption mechanism. Any set of keys can be aggregated and can be made as compact as possible. The user who holds the key can release the constant size key that is aggregated for the different choices of ciphertexts within the cloud storage. Even though, the users can release those aggregate keys, the other files that are encrypted will be kept confidential. The aggregated key can be securely stored in the smart cards.
