An upcoming cloud service called "secure cloud storage" is meant to safeguard the privacy of data that is outsourced while also giving cloud users who have data that is not under their physical control flexible access. Policy Attribute-Based Encryption (CP-ABE) with cipher text is considered one of the most promising methods that may be used to ensure service guarantee security. However, because of CP-ABE's inherent "all-or-nothing" decryption characteristic, using it may inevitably result in a security compromise known as the misuse of access credentials (i.e., decryption privileges). This project looks into two primary scenarios of access credential misuse in this paper: one involves a semi-trusted authority and the other involves a cloud user. Our proposal, called Crypt Cloud, is the first responsible authority and revocable cloud storage solution based on CP-ABE with white-box traceability and auditing to reduce misuse. Additionally, it provides the security analysis and use experiments to show off our system's usefulness
