Abstract

In the cloud, data is usually stored in ciphertext for security. Attribute-based encryption (ABE) is a popular solution for allowing legal data users to access encrypted data, but it has high overhead and is vulnerable to data leakage. The authors propose an anonymous authorization credential and Lagrange interpolation polynomial-based access control scheme in which an access privilege and one secret share are applied for reconstructing the user's decryption key. Because the credential is anonymously bounded with its owner, only the legal authorized user can access and decrypt the encrypted data without leaking any private information.
