Aggregate key generation on cloud data storage using PKC Encryption & Decryption
Keywords:
Cloud storage, Key Gen, Encrypt, Decrypt, Public-key cryptography (PKC).Abstract
The novelty is that one can aggregate any set of secret keys and make them as compact as a single key, but encompassing the puissance of all the keys being aggregated. In other words, the secret key holder can relinquish a constant-size aggregate key for flexible culls of cipher text set in cloud storage, but the other encrypted files outside the set remain confidential. Data sharing is a paramount functionality in cloud storage. In this article, we show how to securely, efficiently, and flexibly share data with others in cloud storage. We describe incipient public-key cryptosystems which engender constant-size (single key) cipher texts such that efficient delegation of decryption rights for any set of cipher texts are possible. This compact aggregate key can be conveniently sent to security channels with very inhibited secure storage. We provide formal security analysis of our schemes in the standard model. We withal describe other application of our schemes.
