Abstract

Sensitive data exposure on the Internet has increased due to the quick development of Internet-based services and applications. Users can save money and save time by using cloud storage instead of keeping local storage, however there are significant privacy and security issues. Data owners may create fine-grained access controls with Ciphertext-Policy Attribute-Based Encryption (CP-ABE), which guarantees that only authorized users can decode the data. This makes it a potential solution. For further protection, especially in cloud contexts, CP-ABE can be used with RSA to add temporal data sensitivity, fine-grained access control, and robust cryptographic foundations. In addition to enforcing stringent access control, this study suggests a unique CP-ABE with RSA (CARSA) approach that identifies the users participating in the decryption process. The proposed CARSA system is shown to be more efficient by experimental assessment, with encryption and decryption timings of 1610 ms and 1098 ms for a 256-bit key length, respectively. By contrast, current methods take 1134 ms and 1691 ms, respectively. According to the findings, CARSA offers improved speed in cloud-based settings while guaranteeing strong data security
