摘要

Blockchain-as-a-Service (BaaS) facilitates cost-effective service delivery across multiple blockchain networks, but secure and controlled cross-chain access remains a challenge. This paper presents a secure and scalable service-level access control framework for interoperable blockchains (SLAC-IB). It is a cross-chain access control framework which utilizes role capability based access control (RCBAC) mechanism for granular, scalable, and adaptable management of cross-chain interactions. SLAC-IB integrates with Hyperledger Cacti to enable secure service invocation and asset sharing, supported by a set of protocols that utilize existing public key infrastructure of the participating blockchain networks. The security properties of the protocol are verified using BAN logic and simulated in Scyther to ensure its robustness against potential attacks. The performance of SLAC-IB is validated through implementation in a Hyperledger Fabric-based environment. Experimental results show that SLAC-IB achieves throughput of more than 1,500 requests per second with response times under 90 milliseconds in caching-enabled scenarios, demonstrating robustness, scalability, and efficiency in high-demand decentralized ecosystems. These results highlight SLAC-IB’s potential for secure cross-chain access control in IoT, cloud, and other large-scale systems.
