Abstract: Secure distributed storage is a newly developed cloud administration that aims to give cloud clients with data that is not under their control flexible information access while also safeguarding the secrecy of reevaluated information. One of the most promising methods for ensuring the assistance is CP-ABE (Ciphertext-Policy Attribute-Based Encryption). Despite this, using CP-ABE may inevitably lead to a cyber attack known as misuse of access accreditation. We analyse two important incidents of access eligibility abuse in this study, one was on the side of moderately power and another in behalf of cloud clients, due to CP's built-in ABE's "go big or go away" decoding component. We introduce CryptCloud+, the first changeable, accountable power, to stop abuse.
