FPIC P25 Transition to AES Encryption White Paper

An excerpt form the FPIC Whitepaper is below

Encryption is the primary means for protecting the confidentiality and providing authentication of sensitive land mobile radio (LMR) voice and data communications. In 2001, the National Institute of Standards and Technology (NIST) established the Advanced Encryption Standard (AES) as the new recommendation for encryption for all federal departments and agencies. In 2005, NIST withdrew its approval of the Data Encryption Standard (DES) and incorporated AES as the new encryption algorithm under the Federal Information Processing Standard (FIPS). However, 18 years later, law enforcement and public safety agencies across all levels of government continue to use DES—a compromised and insecure encryption algorithm.

Most federal agencies have implemented, and are actively using AES for all LMR transactions, but budgetary constraints for many non-federal departments and agencies have continually inhibited the timely and necessary transition to AES.

The transition to AES encryption is the only solution that would provide a lowest common denominator of available interoperable encryption for LMR voice and data communications for all public safety entities at all levels of government.
