Tutorial 4 - ICEDEG 2024
Title: Trust in Digital Government Services Revisited — Will PKI and Blockchain Incorporate in the Zero-Trust Era
Target Audience
This tutorial targets policymakers, decision-makers, public officials, researchers, and practitioners from government, academia, civil society organizations, and enterprises working on government oversight and monitoring at any level familiar with digitalization and digital transformation. No prerequisite technical knowledge is required. Participants should have a basic knowledge of digital government services from the policy-making and architectural point of view.
Importance of Topic
As governments navigate the challenges of the digital world partly brought on by citizens' demand for customized, personalized digital experiences, they need a platform that encourages trust and observability.
Outline
- PKI vs. Blockchain fundamentals: Introduce centralized and decentralized trust for digital government services and analyze their potential incorporation
- PKI Governance: Discuss the most-renowned national trust models and their practicality with digital government services.
- PKI Design best practices: Address the best practices in terms of national PKI design for digital government based on a benchmark study
Certificate Lifecycle Management process (lab activity): Deploy a 2 tier PKI to test Certificate Verification and Chain Building, Certificate Revocation Lists (CRLs), and Online Certificate Status Protocol (OCSP) - PKI operations (lab activity):
- Install and configure offline root CA
- Publish root CA certificate and CRL to CDP and AIA URLs
- Install and configure subordinate CA
- Post-install health checks
- CA Security
- National blockchain applications: Discuss the use of blockchain technology as a hub for national digital government services (based on a benchmark study)
- Blockchain building blocks: Introduce the consensus mechanisms and the distributed storage techniques used in common blockchain platforms
- Deploy a simple blockchain network (lab activity): A set of instructions will be presented and analyzed to demonstrate how customized ERC-20 and ERC-721 tokens can be created and used
- Integration of PKI and Blockchain for Zero-Trust architectures: Discuss the potential beyond the combined use of PKI and Blockchain for digital government services
- Self-Sovereign Identity, the showcase (lab activity): Illustrate the practical combination of PKI and Blockchain in the context of Self-Sovereign Identity for digital government services
