Model-Driven Approach for Generating Smart Contracts for Access Control

Published in: 2023 Fifth International Conference on Blockchain Computing and Applications (BCCA)

Oct 24, 2023

Access controls are principles and policies that are deployed on a system to ensure privileged access to system resources. Role-based access controls are a type of access controls which ensure access to resources based on users' roles. There has been a recent interest in generating smart contracts for the design of access controls. Smart contracts are computerized applications or protocols which execute automatically between contributory entities without an intermediary interference. The smart ...

There is a widespread debate about sustainability and economic growth without posing threats on the planet and humanity. United Arab Emirates (UAE) has set a vital example to be part of UN Sustainable Development Goals (SDGs) as according to Agenda 2030. This paper assesses the policies and plans on accelerating the implementation of the circular economy model in four main sectors—manufacturing, food, infrastructure, and transport. The overall discussion has highlighted the UAE government pla...

Modelling multi-party role-based access control policies for icontractml smart contracts

Published in: 2023 38th IEEE/ACM International Conference on Automated Software Engineering Workshops (ASEW)

We propose a simple modelling language extending iContractML 2.0 for access control policies on smart contracts. The language supports multi-party authorisation and dynamic role-based access control (RBAC) where role members can be added or removed at runtime. Models in this language can be mapped to both Solidity and DAML in a model-driven approach to RBACs.

This research paper aims to investigate smart contracts and Blockchain technology to build a privacy-sensitive application focusing on a Digital Medication Plan (DMR) containing prescriptions. The DMR is used just as a use case. However, the proposed model applies to any context where confidential information is shared and authentication or proof of validity is necessary. We start by presenting the problem to understand the necessity of digitalizing the medication plans and how Blockchain techn...
