This document is a comprehensive guide that provides readers new to the topic of encryption with a discussion of the basic issues related to establishing and maintaining effective encryption for Project 25 (P25) interoperable land mobile radio (LMR) communications systems. The document is an update and combination of previously published documents issued by the FPIC, SAFECOM, and the National Council of Statewide Interoperability Coordinators (NCSWIC) in 2016.
The document can be used as a guide for planning, implementing, and managing an LMR encryption strategy and presents real-world examples of why encryption is important and necessary for protecting sensitive information during critical operations. Finally, the document discusses encryption best practices for P25 LMR systems and information that should be considered when evaluating encryption solutions.
