Title of the Talk:
Programmable Trust: Reimagining Certificate Lifecycles for Cloud Native Security

Abstract :
Cloud native systems demand a security model that moves at the speed of infrastructure. Static certificates and long validity periods no longer align with elastic workloads, microservices, and distributed identity boundaries. To remain resilient, organizations must redesign how cryptographic trust is issued, validated, and retired.
This keynote examines how short lived, automatically provisioned certificates can transform service authentication and strengthen zero trust architectures. By embedding automated rotation, workload identity verification, and policy driven enforcement into certificate lifecycles, enterprises can significantly reduce credential persistence and limit breach impact.
The session will connect applied cryptography principles with real world cloud identity systems, highlighting how programmable trust enables agility without sacrificing assurance. Attendees will gain a practical perspective on building scalable, secure certificate ecosystems that support modern distributed applications while maintaining strong cybersecurity foundations.
