The Physical Security Interoperability Alliance (PSIA) released a new PKOC Explainer Video, created to offer a clear and visual overview of the Public Key Open Credential (PKOC) specification in comparison to symmetric credential options. The video demonstrates the limitations of symmetric encryption in traditional access control credentials and explains how PKOC’s public/private key model enhances security through asymmetric verification.

“As our audience for PSIA specifications grows, we aim to help more people understand what PKOC addresses,” said David Bunzel, executive director, PSIA. “This video was produced to simplify a complex topic — showing how PKOC works and why asymmetric credential verification represents a meaningful step forward for the industry.”

PKOC is a free specification, developed to support secure, interoperable and cost-effective credentialing within the physical security ecosystem. This video is intended as an introductory resource for manufacturers, integrators, consultants and end users seeking to understand the role of asymmetric encryption in modern credential systems.
