2026 Agenda

Project 25 Standards define "Defense in Depth" security for the nation's First Responders through a triad of three unique P25 Communication Security Services, each with an integral key management and delivery process. It is important to understand the unique capabilities that each service offers and how they can be combined and applied offering: confidentiality, Integrity, and availability for P25 voice, data, and network information.

The P25 Communications Services Security Triad:
• Voice and Data Encryption (256 bit AES): Encrypts and protects the voice and data information sent over the air.
• Link Layer Authentication (LLA): Protects the System from access by unauthorized users.
• Link Layer Encryption (LLE, Currently in development): Protects the data and User ID information sent on the Control Channel of the system.

The profile of each service will include a detailed definition of what is protected and how that benefits the First Responder. Veteran system administrators from Connecticut and Pennsylvania will share their keys to successful application including agency policies, radio programming, and encryption key delivery and management. Interoperability with non-encrypted (Clear) radios for multi-agency task forces and incidents will be included. Finally, the P25 Standards development status for new Link Layer Encryption and improved P25 Encryption Key Management functions for Over the Air and manual key delivery will be shared.
