ABSTRACT

An emerging form of cloud administration, secure distributed storage looks to protect sensitive data while still making it easily accessible to users regardless of where their data resides. A promising method that could be used to confirm the administration’s credibility is Encryption Using Ciphertext-Policy Attributes (CP- ABE). However, due to the “win or bust” decoding feature of CP-ABE, its use may result in an inevitable security breach known as the abuse of access certification (for example, unscrambling rights). On the one hand, side of the semi-believed specialist, the other is in, and favour of the an online client; both are studied in this paper. We propose CryptCloud+, a CP-ABE-based distributed storage framework with white-box recognizability and reviewing, to help curb abuse. We also detail the security analysis and provide experimental evidence of our framework value.
