Within cloud environments, Searchable Encryption (SE) serves as a vital tool for protecting data while maintaining its accessibility. The Cipher text-Policy Attribute-Based Keyword Search (CP-ABKS) relies on Ciphertext-Policy Attribute-Based Encryption (CP-ABE) to allow for keyword retrieval and precise access control. However, existing CP-ABKS setups face challenges due to their dependence on a single attribute authority for user certificate validation and secret key distribution. This reliance leads to performance bottlenecks in distributed cloud setups. To address this issue, our research introduces a secure Multi-authority CP-ABKS (MABKS) system. This system aims to overcome these limitations and reduce computational and storage overhead on resource-constrained devices within cloud infrastructures. Additionally, enhancements have been made to the MABKS system to enable the detection of fraudulent attribute authorities and facilitate attribute updates
