Secure Data Sharing With Efficient Cloud Storage

Abstract

In the cloud, for achieving access control and keeping data confidential, the data owners could adopt attribute-based encryption to encrypt the stored data We propose key-aggregate cryptosystem (KAC), a special type of public-key encryption. In KAC, users encrypt files not only under a public key and also with private key. In this we explain how to compress secret keys in public-key cryptosystem which supports delegation of secret keys for different cipher text classes in cloud storage.Our approach is more flexible than hierarchical key assignment which can only save spaces if all key-holders share a similar set of privileges.Here the aggregate key is of constant size. In addition, the proposed scheme is proven to be secure based on kmultilinear Decisional Diffie-Hellman assumption. On the other hand, we implement our scheme over the integers.
