Exploiting Blockchain Technology for Attribute Management in Access Control Systems.

Access Control systems are a key resource in computer secu-rity to properly manage the access to digital resources. Blockchain tech-nology, instead, is a novel technology to decentralise the control and man-agement of a shared state, representing anything from a data repositoryto a distributed virtual machine. We propose to integrate traditionalAccess Control systems with blockchain technology to allow the com-bined system to inherit the desirable properties blockchain technologyprovides, mainly transparency and, consequently, auditability. Depend-ing on the application scenario considered, for some systems it may notbe desirable to employ a fully decentralised approach. As such, in thispaper we outline how our proposal can be adapted to allow for the mini-mal possible integration of blockchain technology in a traditional AccessControl system. In particular, we consider the scenario where AttributeManagers only may be managed on chain through smart contracts. Weprovide a proof of concept implementation based on Ethereum, and showits performance through experimental results.
