Note: registration fees required by IWCE to attend these sessions  

P25 Foundations:

Monday March 5^th **8:30 AM to 11:30 AM** Room N320GH

Offers an overview of the P25 Standards, Interfaces and applications for P25 Conventional and Trunked technologies.  New P25 standards document releases and future work direction will be covered.  The 2018 Focus will be on ISSI/CSSI interoperability between P25 Systems, New Link Layer Encryption and Key fill device standards, P25 for Emergency Communications, and use of P25 in System Procurement and Upgrades.

P25 User Experience:

Monday March 5^th **2:30 PM to 5:30 PM **Room N320GH

Offers Project 25 user experiences and P25 system case studies.  It is structured as a series of presentations from a diverse user group including Federal, State and Local government Systems.  Presentations include P25 system description, its scope, capabilities, agencies served, development history, interoperability achieved, issues resolved, and lessons learned.  Governance structure, and revenue sources will be presented as well as costs for user agency participation.  P25 System interface to Public Safety Broad-band data, and migration will be shared.

P25 Security: New Standards, Applications, Interoperability:

Wednesday March 7^th 4:15 PM to 5:30 PM Room N220E

P25 System Security and Encryption has become increasingly important to protect mission critical communications from unauthorized listeners.  The session will cover: P25 Security Standards updates, enhanced sharing between Key management facilities and devices; and a future new P25 Link Layer Encryption standard.  P25 Authentication and AES encryption applications will be detailed.  Proper planning and coordination is essential to maintain effective communications interoperability.  The panel will address guidelines and best practices for Encryption planning and radio programming applications.

P25 System of the Month: Central Indiana Counties

Summary:

The three-county system has realized many great benefits from sharing common infrastructure utilizing the P25 architecture.  Previously all three counties were required to maintain radios in their respective Public Safety Answering Points (PSAPs) and create patches to the respective jurisdictions.  Patching proved problematic and unreliable at best.  A great many of the field units did not have direct communications with the neighboring jurisdictions, especially during large or critical events.  This created a First Responder safety issue, which the counties realized needed to be addressed as soon as practical.

Since the counties have upgraded to P25, the three counties now share talkgroups including public works talkgroups to allow for greater efficiency.  The counties have created several mutual aid (MA) talkgroups that can roam across all systems in the event of a disaster or large-scale event like the Super Bowl.

An additional benefit of the three counties upgrading to P25 is the ability to have interoperable communications with the State of Indiana’s P25 system.  This system is utilized by hundreds of agencies throughout Indiana as well as Federal Public Safety partners.  No longer do officers need to have multiple radios available to communicate to these important partners.

Project 25 Technology Interest Group Releases New Whitepaper:

Project 25 Radio Authentication

The paper was authored by:

Jim Holthaus, Vice President, Chief Technical Officer, BK Technologies

Project 25 radio standards now provide a method of authenticating subscriber radios for operation on P25 trunked radio systems.  This paper explores the need for and functionality of P25 Link Layer Authentication services on trunked radio systems.

For decades, public safety communications system operators were protected from unauthorized access through the restrictions that equipment manufacturers placed on radio programming equipment.  So even if an unauthorized individual had radio equipment and programming software, without the so called ‘system key’, programming a radio for an individual radio system was not possible.  In general, this level of protection works quite well for many public safety agencies.  However, the use of the system key is only as reliable as the methods used to protect unauthorized access to such a key. 

As the technological abilities of those wishing to steal service or disrupt public safety communications systems expand, additional measures to protect unauthorized access to public safety communications systems are required.

Public Safety and government radio users, through the Project 25 Standards process have requested inclusion of additional measures to prohibit unauthorized access to P25 systems.  The Project 25 standard provides this protection through the use of authentication technology.  The Project 25 standard defines a challenge/response system that allows the radio system and/or subscriber radio to authenticate itself before service is granted.
