The objective of this project to enhance the security features for unauthorized decryption and unauthorized attribute manipulations on data while maintain the features of security. Aiming to make the system more secure and practical for use.
This paper addresses security concerns in Ciphertext-policy attribute-based encryption (CP-ABE) for secure cloud data sharing. It tackles the key escrow problem by introducing a two-party key issuing protocol, preventing compromise by the key authority or cloud service provider. Additionally, the scheme enhances attribute expressiveness through weighted attributes, extending from binary to arbitrary states, reducing access policy complexity. This not only improves data sharing efficiency in cloud computing but also lowers storage costs and encryption complexity for cipher texts. The proposed solution ensures both security and efficiency, making it suitable for practical cloud applications.
