Information Security for Scalable Data Sharing

Information sharing is an important functionality in cloud storage. Here, In this paper, we show how to share data securely, efficiently, and flexibly. A new public-key cryptosystems is demonstrated which produce cipher texts with constant-size such that efficient delegation of decryption rights for any set of ciphertexts are possible. The novelty is that one can aggregate any set of secret keys and make them as a single key, but encompassing the power of all the keys being aggregated. That is, the secret key holder can generate a constant-size aggregate key for flexible choices of ciphertext set in cloud storage, but the other encrypted files with cipher text outside the set can be secure. This compact aggregate key can be sent to others or be stored in a smart card with very limited secure storage. Privacy analysis of our schemes in the standard model and describe other application of our proposed schemes is provided. In particular, our system gives the first public-key patient-controlled encryption for flexible hierarchy, which was yet to be known.
