Empowering Tanzania’s Digital Future with Secure and Scalable Public Key Infrastructure
About the Customer
The Tanzania Communications Regulatory Authority (TCRA) is the regulatory body responsible for overseeing the communications sector in Tanzania. TCRA's mandate includes regulating telecommunications, broadcasting, and postal services, ensuring that these sectors operate efficiently, securely, and in the public's best interest. As Tanzania advances its digital transformation agenda, TCRA plays a pivotal role in ensuring that digital communications and transactions within the country are secure, reliable, and trusted.
Business Scenario
As Tanzania embarked on its journey towards a more digitally driven economy, the need for a secure and trustworthy digital environment became paramount. TCRA recognized that establishing a National Public Key Infrastructure (NPKI) was essential to secure digital identities, facilitate secure online transactions, and support e-government initiatives. However, the challenge lay in designing, implementing, and managing an NPKI system that could meet the high security standards required, while also being scalable to accommodate future growth.
Key challenges included:
Ensuring the security and integrity of digital identities across various sectors. | Integrating the NPKI system with existing governmental and private sector IT infrastructure. | Training officials and stakeholders to manage and operate the NPKI system effectively. | Complying with international standards and local regulations to establish a trusted digital ecosystem. |
eMudhra Solution
eMudhra was selected as the partner to design and implement the National Public Key Infrastructure for Tanzania. Leveraging its extensive experience in digital identity and cybersecurity, eMudhra provided a comprehensive solution that addressed TCRA’s needs.
The solution included:
- emCA (Certification Authority): Implemented as the backbone of the NPKI, emCA manages the entire lifecycle of digital certificates, ensuring their secure issuance, management, and revocation.
- emRA (Registration Authority): Deployed to handle the registration and vetting process for digital certificate requests, emRA ensures that only verified entities are granted digital certificates.
- emBridge: A versatile client tool installed across various platforms (Windows, Mac, Linux) to facilitate secure communication between the client systems and the central NPKI infrastructure.
- emRA Encryption Utility: Utilized for encrypting and decrypting sensitive data during the transmission and storage process, enhancing the overall security of the NPKI.
To ensure the successful implementation and operation of the NPKI, eMudhra also provided extensive training to TCRA officials. The training covered all aspects of the NPKI system, including the use of emCA, emRA, emBridge, and encryption utilities, enabling the officials to effectively manage the infrastructure.
Solution Architecture
The architecture of the NPKI solution deployed by eMudhra is a multi-layered system designed to ensure security, scalability, and interoperability. The key components of the architecture include:
- Certification Authority (CA): emCA forms the core of the NPKI, handling certificate issuance, renewal, and revocation. It is integrated with Hardware Security Modules (HSMs) to securely store cryptographic keys.
- Registration Authority (RA): emRA is responsible for managing the certificate lifecycle, from registration to approval, ensuring that only authenticated users and entities receive certificates.
- Client Integration via emBridge: emBridge facilitates secure communication between client systems (across different operating systems) and the central NPKI system. It supports REST API integrations, making it adaptable to various client environments.
- Data Encryption and Security: The emRA Encryption Utility is used to encrypt sensitive data, ensuring confidentiality and integrity during transmission and storage.
