The P25 Steering Committee, the Compliance Assessment Process and Procedures Task Group (CAPPTG), and the Joint SAFECOM-NCSWIC P25 User Needs Working Group (UNWG) release Project 25 Link Layer Encryption Informational Session
Link Layer Encryption (LLE) is a security service that provides confidentiality for user identities, voice, data, supplementary services, and other information sent over the control channel. This informational session, held on October 11, 2023, was developed to provide a greater understanding of how LLE will work upon completion of the LLE Project 25 (P25) Standard and how it may interface with current P25 land mobile radio (LMR) systems. The P25 LLE Informational Session is led by Telecommunications Industry Association subject matter experts (SME). These SME engineers are members of the APCO Project 25 Interface Committee (APIC) Encryption Task Group (ETG) and are currently developing the LLE P25 standard. The informational session provides a roadmap for public safety users around the development of the LLE P25 standard, how LLE will work to protect the security of P25 land mobile radio (LMR) systems, and a high-level overview of this emerging technology. Find the P25 LLE Informational Session on the CISA YouTube channel and on the CISA website at cisa.gov/safecom/project-25 and cisa.gov/safecom/encryption under the Project 25 menu.
