Public key infrastructure: The cornerstone of modern authentication and authorization
Year: 2025
Type: article
Abstract: Public Key Infrastructure (PKI) is the cornerstone of modern digital security, providing essential mechanisms for authentication and authorization across diverse technological landscapes. With the rising complexity of digital environments and the increasing adoption of cloud services, IoT devices, and Zero Trust architectures, PKI has evolved to meet emerging security challenges. The implementation of PKI encompasses crucial components, including public-private key pairs, certificate authorities, and X.509 certificates, which enable secure communication, identity verification, and access control. Organizations are increasingly leveraging automated certificate management solutions and integrating PKI with advanced authentication standards to address the growing demands of certificate lifecycle management while maintaining robust security postures in distributed environments.
