"SAFECOM and NCSWIC Release LLA and LLE: Are You Really Secure?"

The US Homeland Security Department's Cybersecurity and Infrastructure Security Agency (CISA) is bringing attention to whether there is true security when using a Land Mobile Radio (LMR). Most Project 25 (P25) radio systems include built-in safeguards, but the availability of software key generators and other attack vectors used by threat actors call for the addition of new P25 features to ensure the security of P25 communications. Link Layer Security (LLS) features such as Link Layer Authentication (LLA) and Link Layer Encryption (LLE) have gained attention from manufacturers and users seeking to improve communications security over the years. The whitepaper titled "LLA and LLE: Are You Really Secure?" describes these features and their impact on safeguarding public safety communications, and presents a case study illustrating why these features should be used to provide added LMR system protections. This article continues to discuss the release of a whitepaper on LLA and LLE.
