Connecticut Brushfire P25 Interoperability Case Study

State of Connecticut Statewide Brush Fires 2024:

P25 Interoperability Success

State Regional Coordinator: “One of the biggest challenges during large-scale incidents involving numerous agencies is maintaining clear, consistent communication. However, due to years of strategic pre- planning by the engineers at CTS, we were able to bypass this common obstacle, resulting in outstanding coordination and response efforts.”

“During the brush fire event(s), we were able to work seamlessly with partners from multiple jurisdictions, including out-of-state and even international resources”.

Starting in October, 2024, unprecedented brush fires broke out throughout the state. The response included units from throughout the United States as well as internationally.

Tragically, one firefighter lost his life.

Coordinating this large response over a large area required the use of the trunked radio system. The system supports multiple manufacturers subscriber units. During these incidents, subscribers from at least four different P25 manufacturers were utilized- seamlessly. Learning from other incidents, the State developed and requires the implementation of an “interoperability template” in each and every subscriber unit on the system. These common sets of channels and talkgroups permit interoperability on the fly without the need for reprogramming at an incident.

Security Triad for P25 LMR: Encryption, Access, Cyber IDs

Today Project 25 offers Defense in Depth 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 Security Triad assures access control, privacy protection, information modification prevention, and timely reliable access for the nation's Telecommunicators and First Responders.

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): 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. Keys to successful application including agency policies, radio programming, and encryption key delivery and management will be detailed. Interoperability with Non encrypted (Clear) radios for Multi-agency task forces and incidents will be included. Finally, the current P25 Standards development status and product availability will be shared.
