ABSTRACT

The advancement of blockchain technology has increased the importance of security and access control in enterprise environments. Hyperledger Fabric, a widely used permissioned blockchain platform, shows limitations in access control. Its current Role-Based Access Control (RBAC) lacks flexibility for enterprise needs, presenting issues in policy management complexity and cross-channel access difficulties. Moreover, access control decision functionality is limited, and integration with existing enterprise identity systems is challenging. This study explores the application of Lattice-Based Access Control (LBAC) using X.509 certificates in Hyperledger Fabric to address these issues. The research proposes encoding LBAC security levels and category information in X.509 certificate extension fields. This approach enables fine-grained, flexible access control while integrating with Fabric's existing authentication framework. This research aims to significantly enhance Hyperledger Fabric's security and flexibility.
