The Public Key Infrastructure (PKI) Regulations, developed by NITDA, establish standards for Certificate Authorities (CAs) to facilitate secure digital communications and transactions. They provide protocols for accreditation, certificate issuance, key management (including revocation and renewal), and cryptographic engineering controls. Detailed security measures, audit requirements, and liability provisions are laid out to uphold trust in electronic signatures, authentication processes, and overall e-commerce activities. The Regulation specifies roles and obligations for all PKI participants, the aim to bolster confidence in Nigeria’s digital transactions.
