Secure Data Distribution with Proxy Re-Encryption in Cloud Computing

Cloud storage services allow users to outsource their data to cloud servers to save local data storage costs. However, unlike using local storage devices, users do not physically manage the data stored on cloud servers However, a way to make sure the cloud user’s knowledge security is turning into the most obstacles that hinder cloud computing from extensive adoption. Proxy reencryption is a promising solution to secure the info sharing within the cloud computing. It enables an information owner to write shared data in cloud beneath its own public key, that is any remodeled by a semi trusted cloud server into associate coding meant for the legitimate recipient for access management. This paper offers a solid and provoking survey of proxy reencryption from completely different views to offer a much better understanding of this primitive. Specifically, we reviewed the progressive of the proxy reencryption by investigation the design philosophy, examining the safety models and comparing the potency and security proofs of existing schemes.
