Zambia is accelerating its digital transformation. On Monday, September 7, the country announced the launch of its National Public Key Infrastructure (NPKI), a system designed to strengthen the security and reliability of digital exchanges.
The objective is notably to guarantee the integrity of electronic documents, strengthen user authentication, and reduce the risks of identity theft and document forgery.
Digital Certificates to Secure Exchanges
The NPKI relies on the use of digital certificates to verify the identity of an individual, an organization, or an online service.
This infrastructure is expected to facilitate the deployment of electronic signatures and enhance the security of document exchanges and digital transactions, both within public administration and the private sector.
Zambian authorities are considering its use by several categories of stakeholders, including government services, financial institutions, telecommunications operators, and businesses.
The aim is to create a digital environment in which users can verify with greater certainty the identity of the parties they interact with and the authenticity of exchanged documents.
Trust: A New Challenge for Digital Transformation
The launch of the NPKI comes as African countries continue to develop their digital infrastructure.
According to the AfricaNenda Foundation’s 2025 report on instant payment systems, 36 systems were operational across the continent as of June 2025. These systems are increasingly regarded as one of the components of digital public infrastructure, particularly in the area of payments.
With the growing number of remote services, electronic transactions, and online document exchanges, digital trust is becoming a central issue.
It is no longer enough to allow citizens and businesses to conduct transactions remotely. It is also necessary to ensure that the parties involved are who they claim to be and that the information transmitted has not been altered.
A Recognized Tool for Digital Public Infrastructure
The World Bank considers public key infrastructure and electronic signatures to be important components of digital public infrastructure.
In a note published in 2024, the institution highlighted their role in authenticating digital interactions and protecting the integrity of documents. Their effectiveness, however, depends on the existence of a legal framework that recognizes the validity of electronic signatures and transactions.
For Zambia, the implementation of the NPKI therefore represents another step toward building a more reliable and secure digital ecosystem.
The Challenge of Adoption
The launch of this infrastructure alone, however, does not guarantee its widespread adoption.
Zambian officials have already identified several challenges, including funding, a shortage of available technical expertise, and dependence on foreign suppliers.
The success of the system will therefore depend on the country’s ability to ensure sustainable funding, develop local expertise, and encourage its integration across government agencies, businesses, and financial institutions.
With the NPKI, Zambia is nevertheless laying another cornerstone of its digital transformation, making trust, authentication, and the security of digital exchanges key priorities of its national digital infrastructure.
