Abstract

This study presents a decentralised ciphertext-policy attribute-based encryption (CP-ABE) scheme designed for secure and efficient access control in resource-constrained Internet-of-Things (IoT) environments. By utilising multi-authority architecture and outsourced computation, the scheme enhances scalability, simplifies key management by eliminating reliance on a certificate authority (CA), and ensures data confidentiality through randomised proxy keys. It is particularly suited for multi-scenario IoT applications involving information sharing, such as smart cities or industrial automation in strategic alliances or conglomerates. Demonstrating security against chosen-plaintext attacks under the decisional bilinear Diffie–Hellman assumption, the scheme offers a practical and scalable solution for decentralised access control.
